Site configuration - AP radios off


Userlevel 4
I've setup a site configuration and have the problem that the radios stay turned off. We have two SSIDs (Bridged@AP). Admin mode is on, SSIDs are enabeled on both radios.

The customer use firmware 8.32.14.0002. Did anyone had the same issue?

From time to time this could happen. Most the time the accesspoint did not know his controller. In case of a site survey I would think that you only have one controller, right?

Check that the controller is there configured, if this not work, delete the accesspoint and do a clear to factory default on the accesspoint, add it again to your controller, add the controller's IP to this field and then it should work.

Hi Hartmut,
are the radios still "off" or in "scanning"-mode (See "Active Wirless AP)?
We had trouble in V9 with AP3825, wile some AP are hang in "scanning-mode" - but this should be fixet with the actual V9-release.

If the error will be furthermore, if the AP was reset to factory defaults?

Thanks for the replies, but the is a misunderstand of the term site. I did not mean a site survey.

The site "concept" mean controlling ap im remote branches/remote locations. You can define sites for every branch with different SSID, policies and individual RADIUS config. Now we switched from using sites to a standard configuration with a new VNS and a topologies in Bridged@AP mode. After this config change everythings works fine.

I like to use sites in future to setup local RADIUS servers and only use one central RADIUS server as backup. After moving to firmware 9.x we will try the setting up sites again.

Hamut,

Check your antenna set up in the AP properties tab. Usually when the radios are in off mode following a reboot or system outage, the AP may have lost the antenna type. I have seen this occurrence before following a switch reboot.

Thanks Don, this could only happen to AP model with external antennas. Customer has only AP model with integrated antenna, so this is not the cause of the problem.

Hartmut,

Keep us posted. If you still have issues after upgrading to 9.x we will get a case opened for you. I have two sites customers that I have worked with on 9.21.07 without any issues.

Hello Doug,

I have tested the site feature with 9.21.x successfully, too. But the customer only have some downtime windows so we can't switch to 9.x now. I will update this thread if i have any other findings.

Thanks, the only issue I'm aware of in the 8 and early 9 was if Radar (in-service) was enabled on the AP in Sites mode.

If they are reporting to the controller, but not broadcasting, it is usually a MTU issue. When I send AP's to a remote site, I set the MTU on the AP to 1400. Hope this helps anyone in need

Hello Joseph thats a good idea. I know the right MTU size is important, but I've checked during my short remote session. I will tell my customer to check this.

+1 for MTU isssue - the AP is "green" on the GUI but radio is off.

Check the log - reboot the AP - do you get "Blacklist successfully sent..." then it's OK - if not it's an MTU issue.
