Troubleshooting an AP

unknown

Hi everyone - I'm going to open up a support ticket on this, but thought I would poke around a bit myself first. Basically the problem is that I have an AP that needs to be rebooted once or twice a day. The AP, an R710, is in our school library. Users have excellent signal, but the network just goes wonky. Pinging internal or external devices times out, comes back for a bit, huge response times. Reboot the AP and all is well. I checked the switch that the AP is plugged into for any port errors, but no problems there.

Any tips on what to use to troubleshoot? Going to fire up Wireshark when this happens next time, but was also wondering about interference, etc. The AP is mounted very close to cell phone towers on our roof, but I've read that this shouldn't be a problem or would always be a problem.

Thanks

Hi there,

Would there happen to be any microwave ovens nearby?

Hi,

how are you managing this R710? ZD or vSZ?

unknown

Sorry, ZD3000 with latest OS. I have a total of 66 APs

unknown

There is, but it's not in use when this happens necessarily

Thanks. Which release you are running? 10.2.1.0.xxx?

unknown

Version: 10.2.1.0 build 183

no bugs in version. can you please confirm APs are getting enough power? also are you having issues to a specific device type or all connected devices? have you tried login into the AP via cli when clients dropped? Sorry your issue is not really straighforward so I have to ask these questions to understand what exactly going on? Thanks

How do you confirm they are getting enough power? Devices are MacBooks and iPads. I have not tried to login to the cli when this happens. Thanks for your help!

what PoE switches you are using? if cisco, run "terminal monitor" and then shut no shut the port. see if you are seeing any logs for insufficient power. second option is to run "show power inline" or if Ruckus switches "show inline power" see how much power is given to APs. If you dont have multiple APs experiencing same issues in the environment, this may be an AP issue. Thanks

If its just the same 2 APs - I wonder if there is a code issue/memory problem, etc. you could consider factory defaulting them and re-loading the code to reconnect to the system and see if it resolves it. Otherwise, could consider RMA.

If its possible you could swap a working AP for the problematic one and see if the issue moves or stays the same which could help identify if its the AP or something behind it on the network.
