Currently have two 6000 controllers and two 3200 controllers. All of the controllers except for one has had no issue upgrading to the 188.8.131.52 firmware.
I upgraded to 184.108.40.206 from 220.127.116.11 and on one of the 3200 controllers I am having a bit of issues with it. I upgraded the controller and was not able to access the webpage or SSH after the controller came back online. I was able to ping the controller though.
I have accessed the controller via the console and completely blown away the config, re-setup the interfaces at least to get it onto the network, added another user than just the admin account..etc.. I can plug the controller in and watch the interface start to ping from my workstation. After a few minutes, I am able to access the webpage and login through both the admin and added usernames. I can SSH into the controller as well. After 2-3 minutes, when I click on a link in webpage (say the configuration tab or something in the menu), I get an error from my browser stating I can no longer access the web page. Nothing from then on happens. I can't SSH anymore, can't browse the webpages of the controller. The other admin here is able to SSH into the controller and then after 2-3 minutes...they basically get booted out of the controller and can no longer access it either; through the webpage or SSH.
Any ideas or suggestions? Note: I have completely cleared the config already to default settings and set controller back up only on the interface where I need access to the network and added a username to the device. That's it.
