Introduction
The WILI-O skin was special designed for Point-to-Point (PtP) and Point-to-Multi-Point (PtmP) network scenarios, has additional useful testing tools for created link monitoring.
WILI-O Point to Point Bridging
A bridge in Point-to-Point (PtP) configuration connect two networks in different locations through a single wireless link. This allows two widely separated sites to share resources, including a single high-speed connection to the Internet.
WILI-O Point to Multi Point Bridging
A bridge in Point-to-Multi-Point (PtMP) configuration can connect three or more networks in scattered buildings through wireless links. This allows numerous sites in a wide area to share resources, including a single high-speed connection to the Internet.
WILI-O Access
The WILI device requests an IP address via DHCP by default. If no response is received from the DHCP server then the access point uses the default address 192.168.2.66. If your network has a DHCP server, the IP address will be automatically assigned to the WILI device from DHCP server IP address range. Use WILIBOX Java utility (integrated in the WILI Scout utility) WILI Discovery to locate the device on the network and view its IP address. After the IP address of the WILI device was determinated enter that IP address into a web browser on a computer on the same subnet to login into the WILI device web management:
After successful administrator login you will see the main page of the WILI-O device Web management interface. The WILI-O device now is ready for configuration. For instructions on changing the administrator’s password refer to the corresponding section Account.
General Skin Operation
There are three general actions to manage configuration file using the skin: Refresh status, Apply configuration changes, Save&Reboot to save new device configuration and reboot the device.
Refresh
Pages that displays statistical information or other pages that may change frequently and do not have any configurable items may have a Refresh button. Use this button when need to refresh page information.
For example the information on Wireless Statistics page changes frequently, so refreshing the page often may be beneficial.
Apply
Configuration pages contain a page-wide Apply button at the top of the screen that applies all changes made on a single page to a temporary configuration cache. In previous skin versions, it may have been necessary to click a Change button in multiple sections on the page. This is no longer necessary.
| The Apply button does not save the configuration permanently, only temporary. Once the Apply button is clicked, the SAVE&REBOOT should be used to save the configuration to the device. |
Multiple consecutive pages can be edited by using the Apply button before clicking the SAVE&REBOOT button.
Save & Reboot
After the Apply button is used on any page, the new button SAVE&REBOOT appears near the LOGOUT button on the main menu area. The SAVE&REBOOT button saves all temporary changes made by clicking Apply button to the actual device configuration file and reboots the device.
WILI-O Skin Structure
The main Web management menu is displayed after successfully login into the system (see the figure below). From this menu all essential configuration pages are accessed.

Network
The IP configuration as described below is required for WILI-O management purposes. Use the Configuration | Network menu to setup network settings of the WILI-O device:
IP address – specify the WILI-O IP address [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a static IP address of 192.168.2.66.
Subnet mask – specify the access point’s subnet mask [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a subnet mask of 255.255.255.0.
Default gateway – specify the IP address of the access point’s gateway [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a gateway IP address of 192.168.2.1.
DNS server 1 – specify the IP address of the primary DNS server. The DNS (Domain Name Service) service translates Internet host names into their IP addresses.
DNS server 2 – specify the IP address of the secondary DNS server.
The section Operating mode allows to change operating mode for each WILI-O radio interface:
Operating mode – specify the operating mode of the particular WILI-O radio [Master/Slave]. The device mode depends on the network topology.
- Master – in this mode WILI-O device acts as an Access Point.
- Slave – in this mode WILI-O device connects to a network composed of many Access Points with roaming.
WDS peers – to manage WDS peers.
- Add – add a new WDS peer.
- Delete – remove selected WDS peers.
WDS peer MAC – specify the MAC address of the WILI-O WDS peer [MAC address].
Wireless Basic
 | Before changing radio settings manually verify that your settings will comply with local government regulations. At all times, it is the responsibility of the end-user to ensure that the installation complies with local radio regulations. Refer to the Regulatory Domain/Channels for information about regulatory domains. |
Use the Configuration | Wireless Basic menu to configure country code and wireless settings for each radio such as SSID, IEEE network mode, throughput enhancement, data rates, quality of service and channel:
Country code – choose from drop-down list the country in which you will use the WILI-O device. According to the country chosen the regulatory domain settings change. You are not allowed to select radio channels and RF output power values other the permitted values for your country and regulatory domain.
The next section of the Wireless Basic page includes parameters of each radio interface of the WILI-O device:
Enable radio – specify the status pf the particular radio interface of the WILI-O device.
IEEE mode – specify the wireless network mode. The list of IEEE modes will conform to the wireless network modes supported by the WILI-O radio.
| | The IEEE mode list varies depending on the selected country code in accordance with the regulatory domain. |
Throughput enhancements – enable the Atheros super features [Fast Frame, Packet Bursting, Dynamic Turbo]. Atheros Super AG® enhanced technologies offers the highest actual throughput - 1.5 to 2 times faster than standard 802.11g or 802.11a/g products in the wireless LAN.
- Fast Frames – packet aggregation and timing modifications. The fast frames is only available on A, G and auto IEEE modes.
- Packet Bursting – more data frames per given time period. The packet bursting is only available on A, G and auto IEEE modes.
- Dynamic Turbo – maximizes throughput using multiple channels. Dynamic Turbo is only available on A and G IEEE modes.
SSID – specify the unique name for the wireless network [string]. Default SSID is "WILI-O-R1" but you should change this to a personal wireless network name.
Broadcast SSID – when selected the WILI-O SSID is visible during network scans on a wireless station. When unselected, the WILI-O SSID is not visible and not broadcasted to wireless stations.
Current channel – displays the channel at which the device is operating currently.
Channel – select the channel, or function ‘auto’ from the drop-down list. Multiple frequency channels are available to avoid interference between nearby access points. If you wish to operate more than one access point in overlapping coverage areas, we recommend a distance of at least four channels between the chosen channels. For example, for three Access Points in close proximity choose channels 1, 6 and 11. The auto channel function is used to find the best channel for wireless device communication (either an unused channel or if all are in use that with the lowest measured signal strength).
| | The available channel’s list varies depending on the selected country code and IEEE mode of the WILI-O device. |
The default channel bandwidth for 802.11 radio is 20MHz in 11a mode and 22MHz in 11g mode (for the turbo modes these are the double ones). It is possible to narrow down the bandwidth twice or four times by choosing Half/Quarter rates. Although this will drop down the data transfer rates, the power density will be increased and it may help to achieve greater operation distances (see figure below).
| | The Half/Quarter rates are only available on A and G IEEE mode, the Dynamic Turbo option should be disabled. |
Quality of service (WMM) – enable to support quality of service for prioritizing traffic from the Ethernet to the access point.
Automatic data rate mode – specify the automatic data rate mode status. If this option is specified the WILI-O will use all data rates lower or equal to the value of Data rate (described below).
Data rate, Mbps – select the device data transmission rates in Mbps from the drop-down list.
Wireless Security
Wi-Fi Protected Access (WPA) provides a higher level of protection for wireless LAN client stations as it includes methods for mutual authentication, strong encryption, and data integrity. WPA takes the original master key only as a starting point and derives its encryption keys dynamically from this master key. WPA regularly changes and rotates the encryption keys so that the same encryption key is never used twice. Key exchange is done automatically transparent to the user.
The WPA2 is the second generation of WPA security; providing enterprise and consumer Wi-Fi users with a high level of assurance that only authorized users can access their wireless networks. WPA2 is based on the final IEEE 802.11i amendment to the 802.11 standard.
Use the Configuration | Wireless Security menu to setup wireless security on each radio interface of the WILI-O device:
Authentication method – choose the wireless security and the key selection method from the drop-down list.
- None – do not choose any of wireless security on the particular WILI-O radio interface.
- WPA-PSK-TKIP – choose the WPA security with passphrase, encrypted by the TKIP (Temporal Key Integrity Protocol) algorithm.
- WPA-PSK-CCMP – choose the WPA security with passphrase, encrypted by the AES in Counter mode with CBC-MAC (Temporal Key Integrity Protocol) algorithm.
- WPA2-PSK-TKIP – choose the WPA2 security with passphrase, encrypted by the TKIP (Temporal Key Integrity Protocol) algorithm.
- WPA2-PSK-CCMP – choose the WPA security with passphrase, encrypted by the AES in Counter mode with CBC-MAC (Temporal Key Integrity Protocol) algorithm.
Passphrase – specify the WPA or WPA2 passphrase [8-63 characters]. The passphrase will be converted to pre-shared key format, selected above.
Wireless Advanced
The advanced wireless settings are only for more technically advanced users who have a sufficient knowledge about wireless LAN. These settings should not be changed unless you know what effect the changes will have on WILI-O device.
Use the Configuration | Wireless Advanced menu to setup wireless security on each radio interface of the WILI-O device:
Transmit power – specify the radio transmit power at which the WILI-O transmits data in dBm using slider or enter the value manually. When entering transmit power value manually, the slider position will change according to the entered value. The transmit power level that is actually used is limited to the maximum value allowed by your country's regulatory agency.
ACK timeout – specify the ACK timeout using slider or enter the value manually [integer, 20-520]. This is the amount of time the WILI-O will wait to hear a response from the wireless device. The too low value of the ACK timeout will give very low throughput. A high value may slowdown the link. A low value is far worse then a value slightly too high. ACK Timeout value should be tuned to the optimal value for the maximum system throughput.
Fragmentation – specify the Fragmentation threshold using slider or enter the value manually [256-2346 bytes, or word ‘off’]. This is the maximum size for a packet before data is fragmented into multiple packets. This value should remain at its default setting of 2346. Setting the Fragmentation threshold too low may result in poor network performance. Only minor modifications of this value are recommended.
RTS – specify the RTS threshold using slider or enter the value manually [0-2347bytes, or word ‘off’]. The RTS threshold determines the packet size of a transmission and, through the use of an access point, helps control traffic flow. The default value is 2347 (2347 means that RTS is disabled).
Services
The Configuration | Services menu is used to setup WILI-O system services:
SSH
Use the Configuration | Services menu to setup the SSH service. By default the SSH server is enabled on the 22 port:
Enable SSH – specify the SSH service status.
Port – specify the port for incoming SSH connections [0-65535]. Default: 22.
| | With this service disabled, you would not be able to connect to the WILI-O using the SSH service (e.g. to access the CLI interface). |
Syslog
Use the Configuration | Services menu to configure device to save log messages to the local or remote file using standard syslog facility:
Message level – specify the message level you need to trace. The level determines the importance of the message and the volume of messages generated by the WILI-O. The levels are in order of increasing importance [emergency, alert, critical, error, warning, notice, information, debug]. Default: info.
The WILI-O can be configured to send system log messages to a remote server:
Forward enabled – choose to disable/enable remote log.
Host IP address – specify the remote host IP address where syslog messages will be sent [IP address].
Host port – specify the port to which syslog messages will be forwarded [0-65535]. Default: 514.
Forward message level – specify the message level that will be send to the remote syslog server. The level determines the importance of the message and the volume of messages generated by the WILI-O. The levels are in order of increasing importance [emergency/alert/critical/error/warning/notice/information/debug]. Default: info.
Forward backup enabled – choose to disable/enable remote log backup.
Forward host IP address – specify the backup host IP address where syslog messages will be send to[IP address].
Forward host port – specify the port to which syslog messages will be forwarded [0-65535]. Default: 514.
HTTP
Using the Configuration | Services menu the management of the WILI-O through the HTTP service can be forbidden:
Enable management through HTTP – specify the status of the WILI-O management through HHTP.
| | The WILI-O management through HTTPS is always enabled. |
Expert
| | The Expert Settings are for the advanced users only as after the modification of the configuration file the WILI-O device may get inaccessible or stop operating. |
The modification of the configuration file should be used only in one of the configuration modes either in Skin or in Expert. By default the Skin configuration is enabled:
Configuration editing mode – choose the configuration file editing mode:
- Skin mode – the configuration changes are made using Skin GUI. The possibility to modify configuration file manually and upload custom or backup configuration file is disabled.
- Expert mode – the configuration file changes are made manually or custom/backup file can be uploaded. The possibility to modify configuration file using the Skin GUI is disabled.
| | The configuration file modification in Expert mode has no relation with the Skin configuration. In this case, if you want to configure device using the Skin, after the configuration file was modified in Expert mode, the Skin will not recognize the configuration file and will rewrite some sections that Skin has influence on. Therefore after the configuration in Expert mode, when administrator logs in web management, the Skin rewrites configuration file with Skin configuration sections and offers to Apply changes which overwrite configuration file modified in Expert mode. |
Use Configuration | Expert menu for configuration file download/upload and for edit the device configuration file manually. Editing the configuration file directly can be useful if you need configuration options that are too advanced to be included into the web configuration, or for fine tuning after the web configuration has been used to apply general settings.
Upload new configuration file – use Browse… to specify the system configuration file you want to upload and click the Upload button. The system configuration is uploaded on the system, but does not take affect until the device is rebooted.
Download running configuration file – click to download current device configuration file to your local PC. When needed, that device configuration file could be uploaded to device to have identical configuration that had on configuration download date.
The Edit Configuration section is for editing the configuration file manually. The configuration file entry field is active and ready for editing.
| | Refer to the respective document WILI-S User’s Guide for detailed information about the syntax of the configuration file. |
Save – click to save a modified configuration file to the device flash memory. Modified WILI-O system configuration will become active after device reboot. The system information massage appears with direction to reboot the device. Use the Save&Reboot button to reboot the device and apply device configuration changes.
| | Incorrect configuration file modifications (keys and values) may cause the WILI-O device to stop working. In this case try to upload a known good configuration file or perform a reset to factory defaults (please refer to the respective section Maintenance). |
Reset – use this button to cancel recent changes of the configuration file text. This button is functional before using Save button.
Read active – load the last saved configuration file from device flash memory.
Read backup – load the next-to-last saved configuration file from device flash memory.
Adjust edit area height – select a desired height of the edit area.

License
When the device is installed and ready for use, the valid license file should be uploaded on the device to activate a full set of the device features.
The license status is displayed on the device System Information page:
License status – displays the license validity status:
- valid – this license status means that devise has full functionality of the purchased WILI-S firmware release. With a valid license, you can get all service releases of the purchased FW version for free.
- not valid – this license status provides only a very limited functionality.
| | The device license will be still valid after resetting the device to defaults. |
If the device has an invalid license uploaded, only very limited set of the device functionality is enabled:
- It runs only with a default configuration. Only a single BSSID is allowed; DHCP client runs on WAN interface, DHCP servers run on LAN and Wireless interfaces.
- It is impossible to change the configuration. All features are locked down until a valid license is presented. Any changes made in configuration will be stored in the flash memory of the device. Thus only a default setting will be used after the reboot.
To manage the license file, use the System | License menu:
License status – displays the validity status of current license.
Download current license file – click to download current device license file to your local PC.
License File Upload – click for the license file upload on the device.
To upload a new valid license file on the device use the Upload button under the Upload New License section:
Browse… – click to specify the license file you want to upload on the device.
Upload – click to upload the chosen license file on the device.
| | Be sure for certain you are uploading a valid license file. |
After the new license file is uploaded, the device must be rebooted for changes to take effect. For instructions how to reboot the device, refer to the section Reboot on the Maintenance page.
| | In case the fault license file has been uploaded, the device becomes inactive after reboot and the default configuration will be uploaded with the dynamic IP address given by the local DHCP server. |
Skins
The are two types of skins: build-in and custom. The build-in skins come with a WILI device firmware and are undeletable so even after the device reset to factory defaults the build-in skins will remain. The custom skins are fully manageable - they can be uploaded and deleted from the system by the administrator.
Use the System | Skins page for skin activation, upload or download.
Skin name – displays the name of the particular skin.'
Active – marks which skin is activated on the system.
Type – specifies the type of particular skin:
- build-in – skins that are built in device firmware and cannot be removed. The built-in skins will remain even after device reset to factory defaults.
- custom – skins developed under customers' needs and uploaded to the device manually.
Activate – load and activate selected skin on the system. After the selected skin will be activated, the new web interface appearance will be displayed. The activated skin will be loaded with the running device configuration. If the skin with a different device functionality (for example from WILI-O to WILI-AP) it is recommended to reset the running configuration to the default skin configuration.
| | Take a note that after device configuration reset to the skin default values the IP address of the device and even the administrator's credentials will be changed to the default values of the activated skin. |
| | It is recommended to refresh your browser (Ctrl+F5) after the successful activation of a skin. |
Delete – remove the selected skins from the system. The build-in skins are not removable, only custom skins can be deleted.
Download – download the selected skin to your local PC.
Use the Upload New Skin section to upload custom skins on the WILI device system:
Browse… – click the button to select the new skin archive from a folder on the PC.

Management VLAN
Access to the WILI-O for management purposes can further be limited using VLAN tagging. By defining Management VLAN, the device will only accept management frames that have the appropriate Management VLAN ID. All other frames using any management protocol will be rejected.
Use the System | Management | Management VLAN menu to configure the Management VLAN settings:
Enable VLAN – specify the status of the VLAN tagging for management traffic only.
VLAN ID – specify the VLAN ID [2-4095]. When device interfaces are configured with a specific VLAN ID value, only management frames that matching configured VLAN ID will be accepted by device.
Restrict Management VLAN to interfaces – select interfaces that will be restricted with management VLAN.
| | When you specify a new management VLAN, your HTTP connection to the device is lost. For this reason, you should have a connection between your management station and a port in the new management VLAN or connect to the new management VLAN through a multi-VLAN router. |
RCMS Settings
Remote Configuration Management System (RCMS) is a centralized monitoring and management system for wireless network equipment based on the WILI operating system. The communication between managed devices and the RCMS server is always initiated by an RCMS client service running on every WILI-O device.
Use the System | Management | RCMS menu to configure the RCMS client on the WILI-O device:
Enable RCMS – select to enable RCMS agent settings.
RCMS server URL – specify the URL of the RCMS server that heartbeat notifications will be sent to.
Heartbeat interval – specify the interval, in seconds, between subsequent heartbeat notifications [number]. Default: 30.
Heartbeat timeout – specify the maximum number of seconds to wait for a response from the RCMS server before considering the connection as having timed out [number]. Default: 60.
Statistics update interval – specify the number of seconds in which the statistics will be send to the RCMS server [number]. Default: 300.
Statistics items –
- Name – specify the name of the statistic.

Reset – click to reset the device to factory default values.
Cancel – click to cancel reset process.
Troubleshooting File
WILI skin has an ability to generate a troubleshooting file that contains a valuable information about device configuration, routes, log files, command outputs and etc. Using the troubleshooting file the device itself gathers information instead of you. This is helpful for submitting problems to WILIBOX support team.
Download – click to download the troubleshooting file to your local PC.
Tools
Use the Tools menu to use the following WILI-O device applications:
- Site Survey – to view the list of wireless networks in local graphical area.
- Antenna Alignment – to align WILI-O device antenna.
- Traffic Generator – to perform throughput test.
- Traffic Monitor - to display the connection tracking data.
Site Survey
The Site Survey test shows overview information for wireless networks in a local geographic area.
Using this test, an administrator can scan for working access points, check their operating channels, WEP encryption and see signal/noise levels. An administrator can use this feature to identify a clear channel to set the WILI-S based device to that will not receive interference from adjacent APs.
| | Note that Site Survey function can take several minutes to perform. |
A Site Survey test is performed every time on the startup of the device, therefore the results of the last performed Site Survey test and its time can be found on the page. Thus, to obtain the results, the initiation of the scan is not necessary.
To perform the Site Survey test currently, click the Scan button:
Choose wireless interface – choose the interface on which the Site Survey test will be performed form the drop-down list.
| | The Site Survey is impossible if the selected wireless interface is disabled. |
Scan – click to perform the Site Survey test.
Antenna Alignment
The antenna alignment test measures signal quality between the bridge/access point and other wireless networking devices. For best results during the antenna alignment test, turn off all wireless networking devices within range of the device except the device(s) with which you are trying to align the antenna. Watch the constantly updated display in the antenna alignment test window as you adjust the antenna.
Choose wireless interface – select the wireless interface on which the Antenna Alignment test will be performed.
| | The Antenna Alignment is impossible if the selected wireless interface is disabled |
The Antenna Alignment test results appear when you click the Start button, and finishes when you click Stop button.
Traffic Generator
This test generates TCP/UDP traffic and measures throughput from client to server with current established point-to-point link conditions.
The throughput test requires two endpoints: server on remote point-to-point link host and the client. Operating mode is selected using
Operating mode – specify the operating mode of particular throughput test [server/client].
Throughput test Client endpoint supports the following settings:
Protocol – specify the network protocol of the throughput test [TCP/UDP].
Host – specify the IP address of the device which acts as throughput test server [IP address]. T
Duplex traffic – specify to perform throughput test with simultaneous data transmission in both directions.
Start – click to start the throughput test.
Stop – click to stop the throughput test.
Show Results – click to view the results of the throughput test.
| | Do not forget to stop Server’s side after the throughput test is finished, as the test may influence on the WILI-O device performance. |
Results – displays table of the throughput results.
The throughput test can be used as the primary tool for verification of selected Data rates and ACK timeout settings. Specify the values on the appropriate sections, apply the changes using the Set button and perform the throughput test. The changes will be saved permanently to configuration file after pressing the Save button.
Choose wireless interface – select the wireless interface on which the data rates for throughput test will be set.
Choose data rate – choose the data rate for throughput test.
Current data rate – displays the chosen value of data rates.
Set – set the selected data rate value on running device configuration.
Save – click to save specified values on the configuration file.
| | After the throughput test is performed save the chosen data rates to the configuration file and reboot the device. |
Choose wireless interface – select the wireless interface on which the data rates for throughput test will be set.
ACK timeout – enter the ACK timeout manually or using the slide.
Set – set the selected data rate value on running device configuration.
Save – click to save specified values on the configuration file.
| | After the throughput test is performed save the chosen ACK timeout values to the configuration file and reboot the device. |
Traffic Monitor
Use this tool for connection tracking, based on the IPtables conntrack module. The traffic monitor table displays only those IP Conntrack table entries that are in [ASSURED] state.
To view traffic monitor data, the IP Conntrack module must be loaded using shell command:
# modprobe ip_conntrack
Once loaded the IP Conntrack module will remain until device reboot. Do not forget to disable IP Conntrack module, as it may influence on the WILI-O device performance. To disable this module use command on shell:
# rmmod ip_conntrack
To enable IP Conntrack module once for all, setup WILI device configuration file using the Expert Settings with the following System Modules configuration keys:
modules.status=enabled modules.1.status=enabled modules.1.name=ip_conntrack modules.1.arguments=hashsize=8192
| | Refer to the respective document WILI-S User’s Guide for detailed information about the syntax of the configuration file. |
Use the Refresh button to view the connection tracker’s file data:
The filter options will allow you to specify any of protocol, source IP or port ,and destination IP or port. There is an ability to filter data using multiple keywords by entering them separated by space, e.g. “tcp 200”. Enter these keywords, use Search button and table will be refreshed according the filter results:
| | Do not forget to disable IP Conntrack module, as it may influence on the WILI device performance. |
