I use a Toshiba Satellite M40 Laptop. The model number is PSM40C-SF300E.
The laptop is three years old and has never given me any problems up until now. I used a wireless internet connection primarily on my computer and it worked perfectly. We recently secured the wireless network, and my laptop worked on it for about a day. I tried again the next morning and my laptop would "connect" to the WiFi, but it wouldn't open any webpages, connect to Windows Live Messenger, etc. I figured it must have been something to do with the router/network so I plugged the ethernet cable directly into my computer. It "connected" but once again didn't load any of the pages.
I called Toshiba and they said it was a router issue, called the ISP and they said it was a router problem. I'm on holidays right now and the computer can connect to the WiFi but still nothing loads so it is obviously not a router issue.
Are there any possible settings I may have accidentally changed? Any possible solution to this problem would be very, very helpful. Thanks in advance,
