I was having issues connecting my printer but after the beta fw update, all my PC's and laptops now work just fine to the USB port in the rear. Working with Win XP Pro, Home and Media edition as well as Vista.
Wireless: 3 laptops, 1 netbook and two PC's
Wired: 1 PC
Thanks it was driving me crazy. I was on the phone with tec support for over an hour yesterday and in the end they said the router was defective to send it back
