Wireless does not work after upgrade to Windows 8.1

1

I've recently upgraded my Lenovo g700 to Windows 8.1. After this, I cannot connect to my router via wireless (WPA2). Via a cable goes fine, and I can also connect to my mobile when set up as hotspot. I already updated the wireless device as described here and tried the tips here as well, but nothing works.

I'd appreciate any pointers.

Windows version is 64 bits, hardware id of wireless card Qualcomm Atheros is PCI\VEN_1969%DEV_1090&SUBSYS_380317AA&REV_10 and CC_020000.

The router itself works fine for two other laptops (not windows 8) and worked fine with the lenovo when still on windows 8. Please elaborate on what you would want to know about the access point..

1Have you installed the drivers that specifically support Windows 8.1 and/or tired the generic drivers? If that fails to work we need specific wireless device information. – Ramhound – 2014-04-04T19:25:52.963

i have installed the Broadcom 802.11n Network Adapter (Broadcom). i also tried the one from windows. Both are listed as compatible hardware. – Marc – 2014-04-04T19:37:38.373

@Marc Is Windows 32-bit or 64-bit? What's the hardware ID of the wireless card, as shown in the Device Manager? – and31415 – 2014-04-04T19:49:09.863

1If you can connect to your mobile phone as a hotspot then the device is working. This means the problem is the access point itself. Please provide more information about the configuration of the access point. Provide all information in the question itself. – Ramhound – 2014-04-04T20:14:24.383

I've been struggled for this problem for the last two days after I accident upgrade to 8.1 (I upgrade twice and downgrade twice because the same wireless issue), I'm using wired internet for the last two days until now, I finally got the wireless back after I ran update and reboot, luckily I'm, hope you try this too!
