With any version of Ubuntu I try it seems that I have an issue with wifi.
Try as I might, I cannot make the wifi stay connected. I have since installed iwScanner and I can see that my wifi network is on a different channel to the others in range. I can also see a signal strength of about -60 consistently except every minute or so (sometimes as often as 10seconds apart) it drops to -100 or essentially nothing.
If I boot the same machine into Windows 7 it seems to work okay, other laptops seem to work okay.
It is a Linksys WUSB54GC v.3 which seems according to the community docs to be supported. I am not really that far away from the router and besides my mobile phone connects to the wifi network fine from the same distance.
The router is getting old so I had considered maybe it was a problem with the router (Draytek) but then I should have issues with the other machines.
Network is not broadcasting its SSID and is using WPA2
Also the dropouts to -100 signal are much more frequent when I try to connect to the network using network manager. Every ~2 seconds consistently.
