Networking & Wi-Fi

[Derp]

Earlier today I noticed that after I opened my laptop out of sleep, my wifi was disconnected. I thought nothing of it, restarted my computer and it worked once again. Fast forward a few hours and I once again open my laptop and the wifi is not working. I restart again, to no prevail. My computer recognizes that there are connections available, it just will no longer connect to any. When I try to connect it gives me the "Windows cannot connect to..." message. Of course, the troubleshooter is useless. My computer has an Atheros AR9002WB-1NG wireless adapter. I am running Windows 7 Home Premium, if that makes a difference.

Things I know:

1) My wireless adapter driver is up to date

2) Restarting my computer does nothing to fix the problem

3) Restarting my router/modem does nothing. I have tried two different routers on two totally different connections, both with the same result. I have two other devices (a MacBook and Sony Blu-Ray player) that both connect and run fine on both of the wireless connections. 

4) System restore does nothing. I restored to two different points prior to my problems, but nothing changed.

5) Changing the power management settings did nothing. 

6) Previous to the problems, I didn't make any changes to the system. The last windows update was on the 16th, just started seeing problems today (the 20th)

7) And yes, the wireless switch is on.

So, I am at a loss for solutions. In summary, my computer can recognize wireless networks but not connect to them, a wired connection works, I have tried every troubleshooting method I have found, and it still will not connect.

Good troubleshooting so far! What's your full model number? "P775D" is only partial, but it should be on a label on the bottom.

The wireless adapter driver might be up to date, but have you tried redownloading it and reinstalling it? Sometimes that can help even if it's the same version.

S5378 is the rest of the model number. I did try uninstalling it and reinstalling it. I even tried installing previous versions. Thanks for your help Peter. I think my computer may just be derpy. Last resort I'm going to try a complete system restore to factory default...grr...pain in the butt.

You may want to boot into Safe Mode with Networking to determine if it's an additional application causing the problem. If it works there, we can determine which application is causing the problem. If it doesn't work in Safe Mode, I'd say doing a full system recovery or contacting customer support is the way to go.
