Can I use CDRouter's wireless interfaces without broadcasting my SSID?
WirelessSome wireless routers allow the the SSID to be hidden from normal wireless scans. This mode is often called "Disable SSID broadcast", "Invisible mode", etc. and is usually implemented by including a null SSID in the 802.11 beacon.
This mode is currently supported in CDRouter 5.0 and later releases. The testvar lanChannel must be included in your configuration file when testing devices with hidden SSIDs. The lanChannel testvar specifies the wireless channel used by a specific access point, and when in conjunction with the testvars lanSSID and lanBSSID enable CDRouter to associate with devices using hidden SSIDs.
testvar lanSSID hidden_test_SSID testvar lanBSSID 00:22:b0:b8:8d:8b testvar lanChannel 6
Valid values for lanChannel are: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 149, 153, 157, 161, and 165.
Note that CDRouter may not be able to associate with devices that use automatic channel detection/selection if the lanChannel differs from the channel that is used. We recommend configuring a specific channel on the DUT when using the lanChannel testvar to avoid association issues.
