I just got a new computer. Yay.
The problem is I can't get the Inventel wireless adaptor to work. I've follolwed the official instructions from Orange and those don't work. The thing is, the computer is unaware I've even connected the adaptor.
Someone help!
EDIT: Using a Wanadoo livebox. The CD says Livebox 0.25.

UPDATE: Situation resolved. I'll be using my Dad's 3 dongle until we can get us a new adapter.
