Says I am connected to a wifi signal, but I get "page can not be displayed"

[ComputerDummy#1]

I have a HP laptop with D-links router. The wifi signal was working for a few months and all of a sudden it stopped working. I have tried to reinstall the router and checked everything i could think of but it still isn't working???? I have windows xp and i checked to make sure all my wireless setup was right but still not able to get internet unless i plug straight into the modem. Please offer any advice you can think of. My ex-boyfriend was good with computers, but he isn;'t around and i don't know what to do. Thanks!

If you get the internet through the modem by bypassing the router then it's likely the router has gone bad. Suggest you replace it.
