Hi I'm new to this forum and and would like some advise on my problem. I'm sure its not new, so here goes. My problems began when I downloaded the ICS system 4.0.5, I suddenly couldn't connect to the internet and yje connection with my other computer were cut off, the message showed unknown network. Resetting the router got my computers back on the internet, but the tablet still couldn't connect. My original tablet worked fine with honeycomb 3.2.8, it was sent back to Archos when the system wouldn't work, who could find no faults in connecting on four different routers at the repair centre. They however replaced the tablet but unfortunately its also exhibiting the same faults. It would be appreciated if any member could give me advice on how to get this tablet working, or on how I could revert to the honeycomb system.
