Here's a question for all you computer guys. I currently have a wireless network setup in my house 802.11b which I use with my laptop and Tivo. I would like to upgrade to 802.11g for my laptop while leaving the 802.11b running for the Tivo. Reason being because I have all the hardware already in place for the Tivo. Would this work? I know I would have to buy the router and a network card for the laptop. Thanks!!
