Thread: What does it mean when SSIDs appear and disappear and channels change?

  1. #1

    Default What does it mean when SSIDs appear and disappear and channels change?

    I'm using inSSIDer to look at the wireless setup in my workplace. The SSID is hidden, but my laptop is set up properly to connect to them with WPA2 Enterprise.

    When looking at inSSIDer, I see a several of BSSIDs, but the SSID (the hidden one) will display briefly and then disappear. Also, the channels on the BSSIDs changes from 1 to 6 or from 6 to 11.

    Any idea what is going on?

    Whether you set the SSID to be hidden or not, it is still broadcast at intervals, which is why hiding the SSID as a security measure is pointless. Perhaps inSSIDer is just responding to the occasional transmission of the SSID by briefly displaying it.

    As to the channel changing, is the wireless AP set to auto-select the channel to use? It may be changing it itself.
