Not especially related to my new Mac, is the fact that I recently discovered Wanadoo wireless only works with Wanadoo systems. Hard to believe but true. This meant that:
1. I must use the external wireless adaptor provided by Wanadoo - no others will work
2. My Wanadoo wireless setup will only work with other Wanadoo signals. So when I went to my sister's house, it could see her BT network but wouldn't connect to it. When I emailed Wanadoo to check, they confirmed that this will be the case everywhere. So don't imagine you can be wireless with Wanadoo in airports and coffee shops etc - nope - not unless they happen to be Wanadoo. Be warned!
3. and of course, Wanadoo wireless won't work at all with Macs, so I had to buy a new Netgear modem/router anyway.
So much for the freedom of being with Wanadoo.
