Okay peoples I need help please

I have a 3802i That doesnt feel like it is responding to commands.
My goal is to update to Autonomous but I believe the process has changed since I last did this.
Apparently Mobile express is the thing now.

I have downloaded the latest Mobile Express AIR-AP3800-K9-ME-8-10-151-0.tar and .zip but not for the life of me can I get an upload
or access it via GUI. I have tried using the ap-type command to see what the details are but no love.... after 6 hours its doing me in.
