Laptop or wireless router not working?

Items:
Apple Ibook , osx10, built in airport
router: d-link wireless router

problem:
apple ibook hooks up via wireless to my friends wireless routers, but not to my own........my mothers pc hooks up fine to my wireless router, but not my mac.......the laptop recognizes the router as it appears in the list yet it says its connected but nothing works (internet/messenger programs) ......when i hook up to the router on my mac via wire, it works fine..........so my router works and the airport works (as seen on my friends' routers)

anyone know wuts going on?

 

Is your mothers PC being hooked up wirelessly or wired? If wireless I would look at the possibility of some type of encryption setup that may not be configured on the MAC. If its being hooked up wired maybe your router itself is having wireless problems?

 

I am having the same problem, except..I went out and bought a cheap little wireless adapter and it works. it may be something with the drivers for the card you´re using. For the life of me, I can´t figure out my problem, however, I would borrow someone´s network adapter just to see if that will work in your computer, if not, then you know where the problem is, if it does work, then you have a whole new problem or you can just use a different card. Also, I did answer another link under Linksys and you may want to look at that one as it might be a winsock issue...there is a download there that may help.

 

Try to re-enter your WEP/WPA settings on the Mac, if your not using the encrytion, try to renew the DCHP, I think you will find it under Internet Connections under TCP/IP settings.
