I just bought a Dir 615 and have managed to successfully connect 2 laptops running Vista, a desktop running XP through direct cable, an I-phone and an I Pod. I have another laptop running XP that I can't get to connect properly. The messages tell me that I am connected with excellent signal strength, but when I try to access the internet it doesn't work. I can successfully connect if I use a cable through the Dir 615, but the wireless won't work for me. Any suggestions?
