Just bought an acer aspire one AO751h two weeks ago.
Removed Vista and installed 9.04 immediately.
Worked great.
Wireless was automatic.
Now, no wireless.
Tried on four different wifi's.
The error says there is not wireless signal.
I did nothing as far as the wireless network is concerned.
I did add programs via Synaptic.

How do I tell if it's software or if the card is kaput?
