Wireless failing everyday

Every day at least once and sometimes twice, I have several access points that reboot. They all do it at precisely the same time and it is usually the same AP's - about 8 of them.

I have other access points that do not go down.

Any ideas? Could this be a firmware issue?

Re: Wireless failing everyday

Are those APs connected to WLC or standalone?

Are all of them plugged into the same network branch?

New Member

Re: Wireless failing everyday

The AP's are all on the same subnet but they are standalone. They are plugged into different switches

Re: Wireless failing everyday

Have you tried to syslog a couple of them to a log server to get a clue?

Are they perfectly working right before rebooting?

New Member

Re: Wireless failing everyday

I have them logging to syslog and there are NO error messages.

And they are working perfectly before they reboot

Re: Wireless failing everyday

This sounds more like a routing or spanning-tree issue. What do the switch and/or router logs say?

It could also be caused by network congestion that is affecting routing or spanning-tree. Are you running any backups over the network or other bandwidth intensive jobs at that time?

Re: Wireless failing everyday

There are no errors on any of the switches.

I thinking that it could be congestion, but the access points are spread all over the network. Different buildings, different switches, etc.

Re: Wireless failing everyday

If you are not seeing any errors, what are the interface counters indicating?

Also, are you using dynamic routing? what do the route tables look like?

Re: Wireless failing everyday

I hate to sound ignorant, but how do I do what you are asking? Like the interface counters and the routing questions?

Re: Wireless failing everyday

on the switches & routers:

Without knowing how your network is built, I can only speculate at this point

The interface counters:
