I have an LAP1250 that was running fine for about a year. then about three weeks ago users reported no or low signal strength. After looking at netstumbler, I discovered that the AP was not broadcasting and the users were attaching to an AP way down the office. I reset the AP and then after about a week it stopped broadcasting again and when looking at netstumbler the MAC is listed as not detected. Looking at the AP through the WLC it shows enabled UP but no one can associate to it. Looking at the client list on WLC there are a couple of clients listed as associated but, the linktest fails so, i assume that they are really not associated.
I am never really sure when is stops so, i cannot find anything in the logs and the device is not under warranty,
Any suggestions on troubleshooting this issue would be appreciated.
