I have a 4 AP30 wireless network for Internal and Guest users. These are connected to a Cisco 2960 switch(s) with spanning tree turned off.
Originally, I had 5 APs and one decided to freak out, causing the switches to freak out and take the internal network down. I disconnected the guilty one and everything worked fine for several weeks.
Until today.
Another AP did the same thing. When I unplugged/rebooted it, everything worked fine. I pugged it back in, it all went down. I tried different switches and ports. Same results.
Brought the AP back to my office and it works great with no issues.
So what could be causing this? I thought it was something in the switches but it doesn't seem to be. I've wiped out and redone the Wireless profile twice in case there was something screwy in there.
Sophos originally thought it was looping, causing excessive broadcast across the network? I agreed that could be it and removed the problem AP. But now a second AP is doing the same thing.
All the APs are set to auto channel. Would setting them to different channels stop the potential looping? I'm sure it wouldn't hurt. But if looping is the issue, why?
Has anyone else had this issue? If this were only a wireless issue, I could work around it but when the network goes down, my client gets cranky.
Thanks for reading and hopefully some of y'all have some insight so I can stop chasing my own tail.
