Re: Computer is unable to connect to any networks

Welcome to TSF,

Thanks for the information that you have provided, very helpful.

The Wi-Fi adapter is not showing in your ipconfig/ all output.

Not having any AV or Security Software is not safe. Please download free MSE:
Microsoft Security Essentials - Free Antivirus for Windows

Scan your computer for any possible infections. Along with MSE, please install and run SuperAntiSpyware, the Free Edition. There's no need to post the logs.

See if those helps and find out if you're able to wireless connect. Please let us know if it helps or not.

Re: Computer is unable to connect to any networks

Along with my previous suggestion, download the latest driver of your Intel device from Intel Site, then log on to Safe Mode with Networking by restarting your computer then tapping F8 and selecting this Option.

In this mode, go to Device Manager, uninstall your Intel Driver, then install the new driver. Log back on to Normal Mode and see if you can replicate the issue or not.

Can you please to a print screen of your Device Manager make sure to expand Network Adapters?

Re: Computer is unable to connect to any networks

Good to see, they are all there.
Can you please post another ipconfig /all in a text file?

Re: Computer is unable to connect to any networks

Have you done a System Restore yet? Restore it to a point where you were able to wireless connect.

If that's unsuccessful, please assign Static IP to your WLAN setting.

Please keep us posted.

Re: Computer is unable to connect to any networks

Please check your Add/Remove Programs and see there's any AV/Security/Firewall software installed such as McAfee, Norton, Eset etc.....

Post all of them here.

Re: Computer is unable to connect to any networks

You may try removing the network security from your router then try connecting. If you're able to connect try WEP apply the same security to your computer then try to connect again to your own SSID. Now try WPA2.

Pls give us an update.

Re: Computer is unable to connect to any networks

I can't remember if I have given you an advise to update your router's firmware, it might help.
Connecting to unsecured network is not safe at all. There might be some disagreement between your Wi-Fi adapter with your router :grin:. Others would replace their Wi-Fi adapter just to be on a safe side.

Re: Computer is unable to connect to any networks

Thanks for the update cpkotso.

I would just like to update. I got back to my apartment after winter break. The problem is with password protected wireless networks. I have no problem connecting with either Wired connection, or a wireless network with no password.
