Hi Khan,


Here is some info to get you started;


WLAN interference can be generated by microwave ovens, 2.4 GHz cordless phones, Bluetooth devices, or other electronic equipment that operates in the 2.4 GHz band. Interference also typically comes from other access points (APs) and client devices that belong in the WLAN but that are far enough away so that their signal is weakened or has become corrupted. APs that are not part of the network infrastructure can also cause WLAN interference and are identified as rogue APs. When a site survey is performed, these devices have to be identified and have to be eliminated.

Please remember to rate helpful posts......

I recently ran across a very inexpensive ($100 US) USB-based spectrum analyzer.


I heard about it from someone at Cisco (not an official endorsement, of course):


You can find the unit here:

A spectrum analyzer will look at the RAW RF signals. If you suspect foreign signal interference, this might be worth looking into.
