Dick has a 7 year old ThinkPad, and he can't get on WPA2 Wi-Fi networks. Leo suggests buying a USB WiFi Dongle. That'll take the WPA2 signal for him.
The chatroom says that it's possible to change out the Wi-Fi card on the laptop, but Leo says it's cheaper to go the dongle route. Dick just has to be sure he's using the latest Service Pack of XP (SP3). He'll also get better reception that way.
