I can't believe it, the same thing has happened to me 5 days after purchase. Searched on this forum and found this thread. I typed in the move command for the config files as suggested. It worked perfectly. There is problem here with the system software though. Mine also happened when battery power ran out and the system shut down. On recharge and reboot, no network. It seems to be corrupting the files on shutdown. I'm delighted with finding the solution on this board though. However I suspect many others will just return the aAo as faulty. How do we notify acer or Linpus about the problem?
