WLC 2504 7.4.1 AP randomly shutdown itself

In past, WLC 2504 ran on software version 7.0.116 is working fine but it has an issue with WIN8.

I found that the issue solved by upgrade to version 7.4 and now I upgrade the controller already.

After upgrade I receiving many case about the access points are randomly shutdown anytime everyday. It means disappear on the dashboard.

I am trying to search a message for cause but not see.

Anyone see this issue and how to solve this.

Thanks in advance.

There were certain known bugs in 7.4.x.x affected certain AP models. If you are using 1142 this may be the bug you are hitting CSCud97983

Anyway it most likley to be a bug.. so check with cisco TAC & get a release which will fix those.

Re: WLC 2504 7.4.1 AP randomly shutdown itself

The one thing to understand is that you would probably of been better off upgrading to the latest v7.0.x to solve your issues. That is the most stable version for v7.x. Moving to v7.2.x, v7.3.x, v7.4.c and v7.5.x is just for features needed or ap support. v7.0.x is the only MD release and all the other trains will never be MD:). Just keep that in mind.

Re: WLC 2504 7.4.1 AP randomly shutdown itself

Dear Scott

I have some questions here.. I read about win 8 and the bug  CSCua29504

The solution as say Ratchapas consist in upgrade the WLC. But I remember you wrote we can use TKIP for WPA Auth. and it works fine... I'm correct?

Re: WLC 2504 7.4.1 AP randomly shutdown itself

Hi Daniel,

TKIP for WPA auth is working fine.

In tomorrow, I will upgrade to 7.5.102.0 and will share the result.

Normally, what is a recommend while upgrading on the wireless controller? (such as disconnect all of access point or can upgrade the wireless controller while access points are associating)

Thanks

Push the new firmware to the WLC and then invoke Pre-Image download to all the AP.

One the Pre-Image download is complete, reboot the controller.

Re: WLC 2504 7.4.1 AP randomly shutdown itself

Hi Leo Laohoo,

Invoke pre-image download to AP, What do you mean?

I will download th the new image to WLC after finish it shows save and restart to take effect, right?

I will restart while the AP is online, can I do?

For today I have plan to upgrade to 7.4.110.0

Re: WLC 2504 7.4.1 AP randomly shutdown itself

What Leo means is that you can download the code to the aps while they are still on and servicing clients.. Lessens downtime .. Read this

7.5 is not intended for bug fix... if you need bug fix then get 7.4.110.0 which posted today.

Thanks

Re: WLC 2504 7.4.1 AP randomly shutdown itself

If you update to v7.4.110.0, make sure you also update the FUS image. This will take 35-45 minutes to complete before the WLC comes back online.

Will this fix your issue though, I don't know. You will have to try and then let it run for a while to see.
