How do I troubleshoot my wireless connection to CDRouter when I'm using WPA-RADIUS or WPA2-RADIUS security?

When setting up a wireless connection that uses WPA-RADIUS or WPA2-RADIUS secruity, there are a few configuration options that must be addressed in order for the connection to be properly established. To debug your wireless connection, please try the following steps:

  1. It's a good idea to check that your wireless card detects the router and that it's using WPA or WPA2. To do this, run: 

      # /sbin/iwlist wlan0 scan

    You should get a result with your router's SSID. This result should also include the field "IE". If it does not, confirm that your router is running WPA-RADIUS or WPA2-RADIUS. If it is or you do not see a router with your SSID, restart DriverLoader and re-scan.

  2. Ensure that your router has the same RADIUS password configured as the testvar radiusSecret.

  3. Make sure that testvar enableRADIUSServer is set to "yes".

  4. If you are running CDRouter-Multiport and the RADIUS server is on the LAN side:

    1. Confirm that radiusHost is set to the testvar_group LAN interface running the RADIUS server.

    2. On the testvar_group LAN interface running the RADIUS server, check that the testvar hostIp is configured and is on the same network as the LAN interface. If not, confirm that the hostGateway testvar is configured and is on the same network as the LAN. Also, confirm that the testvar hostMask is configured with the same network mask as the LAN.

    3. Check that the testvar lanUseEAPOL is configured and set to "yes" on your wireless interface.

    4. Confirm that the RADIUS host configured on the RUT is the same address as the hostIp configured on the LAN interface running the RADIUS server.

    5. If your main LAN interface is wireless, you will need to set testvar startOtherLanFirst to "yes". On a related note, make sure that the LAN interface running the RADIUS server is the first one configured and not after a wireless interface. The RADIUS server needs to be brought up before any wireless interfaces using WPA-RADIUS or WPA2-RADIUS authentication.

  5. If the RADIUS server is configured on the WAN side, make sure that testvar lanUseEAPOL is set globally and that the RADIUS server configured on the device under test is the same as the value for testvar remoteHost.

By following the above steps, you should be able to properly set up a wireless connection using WPA-RADIUS or WPA2-RADIUS security using CDRouter.
