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.
What code are you running and what device and driver's are being used to test. You have to be more specific as to the issue. Is the issue all over or in certain areas. Is it some clients or all. Do you have a floor plan with ap locations we can view?
We are running 4.2.130. The devices we are using are laptops (IBM and HP). We can see the symptoms on both. It seems like it is happening everywhere. I am confident that coverage is not an issue. We have more than enough access points.
