Aironet 1200 WAP not broadcasting


I have three Aironet 1200 WAP's that I recently upgraded from VxWorks to IOS. After the upgrade two of the three will not broadcast their SSID. They will also not let anyone connect to the access point. I reset them several times, re-imaged them with different IOS versions but no dice. Can somebody point me into the right direction how to fix this?

Hi Axel,

What IOS version are these running? With versions starting around 12.3(7) this is the default behaviour. Maybe this is what you are running into. Have a look;

Changes to the Default Configuration - Radios Disabled and No Default SSID

In this release, the radio or radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radio or radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points.

From this doc;

Hope this helps!

Simple troubleshooting step:

Compare the config ('show run') of your working AP to the non-working APs and look for differences the 'dot11 ssid' and 'interface dot11radio 0' parameters. As a general rule, only the ip address, hostname, radio channel and (depending on the environment) power settings should be different on each AP in a small office deployment.

On a side note, the upgrade from vxworks to IOS often results in a lot of unnecessary garbage in the configuration, so often it is a good idea to wipe and reconfigure the APs post-upgrade to clean things up.
