Wireless Access

I just bought a Linksys wrt54gs a wireless broadband router, and i ve been trying to connect my ipaq rx3115 to it, and apparently it is connected, at least the wifi icon shows green, as it is connected, but when i try to access the binternet it doesnt connect to anything or show any message...what can i do? what could be wrong?

For starters, do you know if the Linksys WRT54GS is properly connected to your ISP and the Internet? Check the documentation that came with the Linksys, and use a PC to log on to the router to check its settings.
I would assume the router has a status page to show its connection to your ISP, and also a status page to show what systems are connected to it. Is your iPaq listed in the connected systems display?
