2602 lightweight AP losing config on reboot

[fowlermp1]

Anyone encountered an issue with the 2602E access points losing config everytime they lose power?

I have a 5508 WLC running 7.4.121.0 code and two 2602E Flexconnect access points that everytime they lose power they default their configuration. The APs are located at a remote site connected via MPLS and are configured for FlexConnect with local switching. The 2602Es will re-associate with the WLC since the DHCP option 43 points them to it, they just show up with the default config.

I have three 2602E models at the site but only two of them are doing this, the third comes back up and associates and has retained its configuration. I also have several 1142 models at the site and they behave normally.

Hi,

is there are any secondary controllers in your environment? The primary and secondary controllers for a FlexConnect access point must have the same configuration. Otherwise, the access point might lose its configuration.

There are no secondary controllers, just the primary. These two access points lose all configuration, name, ap group, flexconnect group,flexconnect setting, everything. Its like they are new out of the box and associating for the first time. I have a third 2602E located att the same site and have tested it via power reset and reboots and it retains all config. Both the AP that retains its info and the two that dont are all running the same code/boot version/etc. I cant see any difference in their configuration.

Hi,

I have this problem too.  Have you solved your issue?

Thanks,

Eric, I had this issue after converting an AAP to LWAP. Once the AP was joined to the controller I could configure all the AP settings, shut the power off to the AP and it would loose its configuration. To fix it I pushed the code from the controller down to the AP and that did the trick.

There are different ways to approach this.... many times, just deleting the images and uploading a new rcv images can fix the issue.  Other times, it might be crash files that is taking up a lot of the flash and or erasing the nvram and deleting the images and uploading the rcv is the fix.  When those don't work, then its time to RMA.

Eric,

I was never able to fix the issue. luckily for me, the APs were still under warranty and we had them RMA replacements. I believe the NVRAM was bad in the two. We havent run into any  more that are doing it in the batch we had.

I had the same problem on two AIR-LAP1242AG

I solved by formatting flash memory and reloading the image BEFORE rebooting the device

format flash:
