We have 2 Cisco WLC 4404s and 38 LAP1242AG access points. Approx. half of the APs associate with one WLC and the other half on the other. We are experiencing speed fluctuations when stationary and lose of connection and speed fluctuations when walking around. Cisco has "verified" that all of my setting are correct (but the engineer didnt seem to sure of himself). We do not believe this to be related to any interference. Any help would be greatly appreciated.
