Wireless wont connect

[HTRN]

Ok I'll try and make this understandable, but I'm not a network person AT ALL.

I hooked up a netgear wireless router , and it works, got one pc wired to it.

I put in a usb wireless fob into a pc and got it working, the monitor it the tray see's the netgear router, and I enter my password and it connects. Now the other tray Icon ( the little pc monitor with the wireless signal) connects but says limited or no connectivity. I've tryed uninstalling everything, renewing the IP , but still it doesnt see any wireless to connect to?

Any ideals ???? I hate wireless
