I upgraded the 4402 to version 6 by upgrading to 4.1.192 mesh and then to 6. I could see 4.1.192 but after upgrading I could not get into the gui. I could telnet in but that was pretty brutal. What did I do wrong?

Hi Gary,

You upgraded from a Mesh firmware to LWAP firmware?

Have you tried http:// and https://?

I know you don't want to hear this, but you may want to try blowing away the config (cold boot with a console cable attached, you'll see the prompt when it asks you to log on).

Actually when 6 installs it blows away the config. I had to come in and hook up the console cable. I usually hook one up to a laptop so I can always get to the controller but I didn't this time. I thought it was something I did but this controller proceeded to upgrade a controller in another building 20 miles away. The users complained they couldn't log in. When I got there and hooked up the console cable and rebooted version 6 got installed on there and the config was blown away. I had to tell it to boot from the secondary because I have some 1000 series APs still there. I had to recreate it and now everything is fine.
