Hmm, well I have setup this new part wireless network "propely" now, but am still having some trouble. I am using my Belkin USB Wireless-G adaptor to type this, but a few minutes ago it went wrong.
Basically, whilst using it it seems to diconnect itself from USB
. I'll just hear the windows noise for a device being disconnected from USB followed by the connection noise. Upon reconnecting itself (it randomly does this) I get a message "hi-speed device plugged into non hi-speed port" and the connection cannot be re-established. When I switch off and back on, I can get it back, but this is very inconvenient. Any ideas about this? I am using WPA-PSK security now, however it did this last night on isketch too when I was using WEP, so it suggests it isn't to do with this. Total noob, sorry
