G780 wireless stopped working; networks found but can't connect

I have a G780 bought early this year. It came with Windows 8, which I am still using. Everything was working just fine until today. All of a sudden I can't connect to my wireless networks (I have a router that can have a "guest network" in addition to the normal one, and I can't connect to either of these). I had been fiddling with some of the settings last night, but everything had still been working fine. I can connect with other devices so I know the networks are working.

 

The networks do show up in the list of available networks, but whenever I try and connect it just doesn't work. To make sure I wasn't just typing the passwords incorrectly I tried disabling all security on one of the networks (so it was a totally open network with no password), and the laptop still can't connect. I've tried restarting the wireless router, restarting the computer, updating the driver for the wireless card, uninstalling the drivers and reinstalling them, enabling and disabling the wireless card, unchecking the option to allow the computer to turn off the wireless card to save power, and as a last ditch effort I even did this Windows 8 "Refresh" option which uninstalls all programs you've installed and resets options to the defaults. That also included uninstalling my antivirus program, so I've tried connecting without that, too. Nothing has made any difference.

 

Edited to add that I also downloaded and ran the diagnostic tool from the Lenovo site for my laptop and version of Windows for wireless networking issues and it didn't show anything.

 

I would really appreciate any insight as to what to do next. I'm pretty much at my wits' end with this.

Re: G780 wireless stopped working; networks found but can't connect

hi Maltiriel,

 

Thanks for using Lenovo Community Forums!

 

Can you try doing a system restore, maybe set it 2 days back or when you last work with the Wireless with no issues,

If that doesn't help,

 

Pull up the page on the right where it shows you all available wireless networks,

  > Look for your Network and do a right click make sure you "Forget" the network first,

  >Now Try following this Article and Connect to your Wifi Manually,

http://www.op97.org/technology/documents/1HowtoManuallyConnecttoaWirelessNetwork.pdf

 

Can you also share what it says when you connect to your network

thanks,

 

Best Regards

Solid Cruver

Re: G780 wireless stopped working; networks found but can't connect

Hi, thanks so much for the response.

 

I forgot to add that I did try removing/forgetting the network profiles (multiple times) and then readding both manually as in the link you provided and through the wireless connection app or whatever it is (page on the right as you called it). I was working on this for several hours last night so I tried a lot of things...

 

Every time it just says "Can't connect to network". There's no detailed error message unfortunately. Also, I don't know if it's relevant but for one of my networks, which uses WEP, it never asks for the password. Just tries to connect and can't. For the other one, using WPA2, it does ask for the password. Just in case that's helpful.

 

Would the laptop be set up to be able to do system restores automatically? I don't think I ever set anything up to do that... Where would I look for the option to do that?

Re: G780 wireless stopped working; networks found but can't connect

hi Maltiriel,

 

For some changes like system updates and some application installation they have a protocol to save a restore point,

 

 On your desktop screen press (WIndows key+R) to pull up the run command.

          type rstrui then hit enter, Click next and it should give you the date and time of available Restore points,

          There is also a check box at the lower left where it says show more restore points that you can click that to check for more restore points,

          Choose a date that is Most Recent that you know your wireless is ok,

 

Best Regards

Solid Cruver,

Unfortunately it says that no restore points have been created.

Re: G780 wireless stopped working; networks found but can't connect

This is the strangest thing ever. I decided to give it a try again just for the heck of it and magically it suddenly works. I can now connect to both networks just fine. I did nothing after my last try last night except put the computer into hibernation... I don't know how it's working now, but I appreciate the help! I'm going to go create a restore point right now, just in case. Thanks for your replies!
