Locked

We use wightcable and she has virgin media, they use a netgear router (not sure of the model)

I scanned it and everything. I took the laptop back to my house and the internet works fine here, but at my grans it dosent load those websites etc when using wireless, but my laptop works fine on both networks o.O Is it possible that the router isn't compatible or the mtu size?

This only happens when it is using the wireless connection, but when it is pluged in via the ethernet it works fine.... I tryed uninstalling the wireless driver and reinstalled it

Im unable to ping websites like google etc but when i open ie8 i can view them fine. Certain websites wont load either (only parts of them) for example i cant load ebays sign/register in page or face books sign in page. I cant download any updates (windows,spybots search and destroy,java, cant even download firefox but can view its pages) The computer has just been restored to its origoanl state using acers recovery partition. Running windows xp

Everytime i try to login to the admin account (Not Administrator) the welcome screen keeps loading. I can login to the guest account (The only other account on the system). I tryed to add another account but it promts for the admin account password, i entered it and then it will keep loading/crash again. My main concern is loosing work that id need for college, any one got any idea how to fix this problem or just backup the files from the admin account?
