I recently bought an Acer One Aspire netbook at Dick Smith in Brisbane, Australia and encountered with a similar problem, however I had just found a solution. At first when the wireless adapter on the netbook detected my router's connection, it asked for a wep key, which at the time, I did not know what it was so I typed whatever I thought it was. Ever since then, I was able to get the correct wep key, so I clicked on the connection found, and thought that a way to re enter the new wep key was to point at the found connection, and click what showed on the left hand side 'change advanced settings'. I clicked on the second tab (I think it was wireless connection), clicked on the original connection found, right clicked, and entered the new wep key in the fields found by clicking the 2nd tab on the connection. It worked; but only temporarily as the netbook would show a 'not connected' icon even though I was able to browse on the Internet, and the connection would drop out every 5 mins. A solution to this problem , is to click 'change advanced settings' on the wireless networks window, click on the 'wireless connection' tab, and remove your main connection's router. Then, refresh for a new list of available connections, click on the main connection again, and re enter the wep key NOW and you will find that not only the icon shows as 'connected', no more dropping out occurs, and the netbook connects automatically to the Internet whenever it is switched on; pretty much permanently =-) Hope this helped. I also recommend the previous posts on turning off adapter power save mode + getting your connection right as soon as you open your new acer aspire one netbook/re do everything if you had made attempts.
