12.3(2)JA 'disappearing' GUI?

[jason_fingerman]

I am trying to upgrade my 350s and 1200s from 12.2(15)JA to 12.3(2)JA using the WLSE. When I update the access point the HTTP interface is there at first. After 15 minutes or so, I lose the web interface. I can still browse the various pages but they contain no information... no MAC addresses, SSIDs, IP info, etc. Anyone else having problems such as this?

You can restore the IOS GUI by following the Reloading the Access Point Image Using the MODE Button or Reloading the Bridge Image Using the MODE Button procedures listed in the Configuration Guide; however, any existing configuration in the device are lost.
