2 computers on wireless network and one doesn't connect now. Help, please!?

-Ok, I have a Netgear router in the basement that splits to different things throughout the house (x-box, Dish DVR, etc) and also to a brainless wireless router upstairs. We have two laptops and both connected just fine to the network until a couple of days ago. The older laptop works fine but the newer one connects to the wireless router but doesn't connect to the internet. I tried connecting hard wire from the laptop to the Netgear router in the basement and still the same thing. No problems connecting to the internet with anything else in the house. The newer laptop is running Vista and there haven't been any new downloads lately or new programs. I also did a system restore to about 3 weeks ago before the problem started and still the same thing. I could understand if the wireless card went bad then it would not connect to the wireless router at all. Just baffles me to no end. Any help or suggestions would be greatly appreciated. Thanks.It could be the Wireless LAN Adapter has stopped working.



My mother got a brand new desktop with a built-in Wireless Adapter and a month or so it went out.



I'm not sure how she fixed the problem, but that could be the reason it's not working.
Check your network adapters in your Device Manager, see if the drivers are still there. You may need to reinstall them. you may have lost your driver when you did a system restore. Its just a guess Another guess is , do you have your wireless button on your laptop turned off? They are easy to bump and turn off if you arent carefull ,, just picking it up to go to a different room or something simple like that could do it if you put your thumb in the wrong place,,,another thing to check is open your web browser and make sure the "Work Offline" box isnt checked.
