Hi, I've recently set up a guest wireless in my office, using a WLC 2504 controlling 4 1142 APs. They have been working great for about a month, but as of yesterday, the Wifi signal from 2 of the APs began to pulse - 5 seconds on, 1 second off - which makes it unusable. They are connected as such:
WLC direct to 3750, to another 3750 (~200ft run), to 1142 AP1 (~100ft) THIS AP IS PULSING
WLC direct to 3750, to another 3750 (~25ft run), 1142 AP2 (~50ft) THIS AP IS PULSING
WLC direct to 3750, to another 3750 (~25ft run), to 1142 AP3 (~200ft) THIS AP IS WORKING NORMALLY
WLC direct to 3750, to media transfer, 1000ft fibre to media transfer, to 3750 (~6ft), to 1142 AP (200ft) THIS AP IS WORKING NORMALLY
All APs are receiving PoE from their last 3750 (at default levels). I've cycled the individual APs, as well as the WLC, but the issue remains.
Except for the initial 3750 directly connected, all other 3750's are different.
I not very familiar with the WLC/APs, so if you need more information to help me, please ask.
When I say pulsating, I'm speaking in regards to the WiFi signal of the AP 1142. The signal comes up for about 5 seconds, then disappears. After a second or two, it's back, but disappears again. All of the APs are set at power level 1, and nothing else on the 3750's have PoE enable, so the power should be stable.
I don't see anything that sticks out in the log, but I am not very familiar with the WLC. I've attached a copy of the log so you can take a look. I had to reboot the WLC this morning so the logs are a bit short.
I would just do a continuous ping and see of you still have connectivity even though your device fails I show the SSID. If the ping does not drop, then it's probably your device. Upgrade the driver perhaps.
