I didn't know I could connect a wireless router WITHOUT putting a wireless card into my PC. My understanding from HP was that I had to do that. I most certainly have zero interest in making my PC wireless. But I am also purchasing a laptop which comes with 802.11n already installed. So I figured that Wireless N was the way to go, so that the laptop can function as fast as possible. I do understand that the PS3 has the slower connectivity and won't use the Wireless N functionality. Sadly, I don't understand a word you said about skipping the wireless card in the computer & just using a bit of ethernet cable to connect (connect what?) and use the wireless for the PS3. I thought I had to put the wireless card into the PC in order for it to "talk" to the router and that the router goes on my desk after the cable modem. I'm also concerned about my wireless phone. It's 5.8GHz. Will the router or the PS3 interfere?
I'm rapidly coming to the conclusion that I should pay The Geek Squad to come and do this for me, methinks.
