Well I bought & installed a NetGear DGN2200 last night and it works perfectly. 54Mbps Wifi connection from the laptop, and it completely auto-configured itself - just plugged it in, switched it on, and 2 minutes later connected to the internet. All I did was change the admin password to stop any drive-by chancers from getting into it.
It's 802.11n 2.4GHz BTW.
