I have wireless connection but browser comes up with error

[cecil]

my laptop doesn't want to connect to the internet even though I suposedly have a wireless connection I am running xp pro on it and I tried with IE. firefox and MSN messenger but still will not connect... I am able to disconnect the eithernet from my desk top and it works that way so I assume there is someting wrong with my wireless card or something? my wireless card is a 802.11g wireless cardbus pc adapter... I had this problem before and i left it for a couple days and was able to use it agian (odd) anyone have any ideas?

Thanks
