thomas--plugging the cablemodem directly into the ethernet port was a good way to isolate the search problems from airport problems. jum's experience with network problems is extensive--he was the one who solved a problem I'd had for months (turned out to be my ISP). FWIW, I tried every p2p app I could until jum figured out what was going on, but experience proved LW, its developers and users were the best for the Mac, especially when there were problems. YMMV. If you were able to connect directly with the firewall turned off and still showed no incoming connections after 15 minutes, there really is something wrong.
