i have been the internet (for a couple of months) with no problems, everything was working fine but a couple of weeks ago my 'access' started to change and say local only, stopping me from viewing certain websites, pictures would not load and would then take to to the 'cannot display webpage'. when i try to diagnose it, it either says that windows could not find a problem with the connection, 'the problem has been resolved' (though it doesn't say what the problem actually was, and it isn't resolved as a couple of minutes later it will do it again), or it gives me the option to reset the network adapter and then says it has been resolved again (it hasn't). im running windows vista. using wireless internet connection and it always says that my signal strength is excellent.
i have no idea what it could be as i had not been doing anything differently with it when the problem started, help please.
