Ok, my technological know-how is non-existent, so please bare with me. I own a Powerbook G4 (12" 1.5 ghz) as well as an HP PC Pentium 4 (2 ghz). I have DSL internet service, using a Speedstream modem. I have the modem connected to a Belkin switch which runs a line to the PC and another line to an Airport Express (which transmits to the Powerbook). A few days ago I could not get onto the internet with the Powerbook. To this day I still can't get on the internet using the Airport Express, but I can using the ethernet connection. However, I cannot connect the PC and the Powerbook to the internet at the same time. I never had this type of a problem before. As long as I disconnect the Powerbook from the internet I can access it with the PC and vice-versa. I do not want this scenario. I need to have access to the internet with both computers at the same time. I would like to get this resolved soon, for I am expecting a new iMac any day now, and my internet provider (soon to be ex provider if they keep up their crappy customer service) has been of no help whatsoever. Can anyone shed some light as to what is going on here and what I could do to fix the problem? Thank you in advance.
