How to check if there are problems with the WiFi card?

I have a Sager 8150 with the Intel 6230 Wireless card. The wifi was working perfectly fine last night, but now it will only find and recognize the various networks, but won't connect. The troubleshooter finds no problems with it, and I can connect using an ethernet cable (which is what I'm doing right now). Is there any software to help check this problem out, or am I going to have to open it up and check it out? I wouldn't even know what to look for. Everybody else in the house is able to also connect wirelessly.

 

I have seen similar issues like that and found that it was actually tied to the Windows software. Are you running on Windows 7 Home Premium? Pro? Ultimate? I only seemed to run into the issue when it was the Windows 7 Home Premium because of the way it was identifying the networks. If you open up your network and sharing center is it labeling the network as "connected with no internet access" or is it not connecting at all?

 

It wasn't connecting at all, though I just got it working by reinstalling the driver that Sager has on their website.

 

Good to hear! My next question was the driver but sounds like you are on top of it!
