I do have a onnectivity problem on my o2 ...

I am having a problem with my o2 xda atom running wm5.0

I have a wireless router at home connected to a cable modem. I have set up
the wifi card on the pda. I go to wi-fi utility and I can ping sites on the
internet. No problems there.

Then I start Internet Explorer. I try to go to a web page and I get a
message box saying "The page cannot be found. Check the name and try again".
There is nothing at all wrong with the name, it IE does this for every web
page.

It seems IE doesn't know it is supposed to use the wifi card to connect to
the internet. How do I tell it to do this? Or if that's not the problem, can
someone tell me how to fix this?pls mail the solution to harsivrules@gmail.com
