Unable to connect to own wifi network

Hi
I've searched the web endlessly trying to solve this problem with one of my laptops - without any luck at all. Hoping someone here is able to assist.

My main PC, 2 laptops, an iPhone and an iPad all connect to my home wifi network. All worked perfectly until 3 days ago.

The 2 laptops and my PC all run Windows 8.1 (all updated). 3 days ago my Toshiba Qosmio stopped being able to connect to my home network. All other devices still connect perfectly.

The Qosmio doesn't detect my wifi network. I immediately went to the network adapter's (Qualcomm Atheros) website and downloaded the latest driver. Installed it and for a brief (very brief) time it could once again detect and connect to the network. Last 3 days unable to either detect or connect.

It detects other networks fine, and has no problems connecting to any other network - except mine (doesn't even detect mine anymore). It connects to the iPhone (when used as a hotspot) without any issues.

I've uninstalled and re-installed the new driver, re-booted the wireless router (several times), re-set the router to factory settings, used Windows trouble shooter, checked & deleted the netsh profiles. Re-booted the laptop a dozen + times, disabled (& uninstalled software) for the laptop's Bluetooth.

It simply stopped working.

I've tried everything I can find on the web - without any success at all. I've had the laptop sitting only a few cm from the router.


Not sure where else I can go with this now - it has quite defeated me. If anyone has any suggestions, please help. Getting very, very frustrated.

Thanks

how does the LAN work is it connecting? Do you have Reserve IP for each of your devices on your router?

Hi
The LAN works perfectly.

I tried the find new driver, selected the wifi adaptor from the list of devices - it then found the network, when I tried to connect I got the usual "unable to connect to this network" and the network then was no longer detected. Back to square one.
Sat the other Win 8.1 laptop next to it- it connected immediately.

In the end, I reformatted and re-installed Windows 8.1 - it now connects perfectly.
I spent more time trying to fix it than it took to reinstall Windows.
Thanks

Go to Desktop Mode, press Window Key & X key. It will bring up a context menu. Choose "Command Prompt (Administrator)". Then enter the following without quotes: "netsh wlan show all". The output from it, you need to paste into a post on here. If you do not know how to copy from a Command window. Just right click on the top bar of the window, choose "Select All", then "Copy". Then paste the output on here.
