Installed tiger on saturday night with everything going well except one thing, I can't log on into my wireless network anymore. It will show full bars that my wireless is connected, then drop. Plus, everytime that my powerbook was on my network, it would kick my desktop PC off as well. So I would turn wireless on my powerbook, and with that no longer on the network, the pc would join fine. But once the powerbook was back on, BAM, kicks everything off. Hooking it up with an ethernet cable produced the same thing. So I lose the Dlink router and setup my airport express as a router. I set it up with the powerbook and now it can get on the web fine. No problems. So now my current setup has my airport express running the show, both the powerbook and pc are working fine. (and seems to be running the internet faster with the express, both of them) So I'm not the best with networking, just the basics, but I have no idea what to do to get my dlink router to work again. Any others have this problem? or any solutions?
