Qualcomm Atheros AR9485WB-EG - wireless adapter occasionally loses connection (Windows 8.1)

Hello,

I have an ASUS S451LB laptop.

Running Windows 8.1.

Using Qualcomm Atheros AR9485WB-EG Wireless Network Adapter.

I have an extremely annoying problem lately - I am surfing the web, connected to my home network through WiFi, and every now and then (approximately once an hour or so) my network connection fails. The network notification doesn't show an exclamation mark or anything, everything seems fine but a connection would not be established and I would not be able to use the internet for about 1-3 minutes. Sometimes the problem would fix itself and my connection would renew, and sometimes I rather not wait and when I open the troubleshooting program it resets my WiFi adapter and reconnects to my home network and everything is normal again.

I have two other laptops connected to my home network (Both HP laptops, one is on win7, the other is 8.1) that do not suffer from this odd wireless behavior. Same goes for my android devices, they never fail the connection to my home network. In addition to that I've also connected to my router directly using cable connection for a few days, and never suffered these connection disturbances. Therefore I presume the problem lies within my ASUS laptop's WiFi adapter.

Yesterday I've tried reinstalling the drivers version 10.0.0.263 (currently the latest), also reinstalled the whole Qualcomm bluetooth connection suite as well and problem still persists.

If anyone could shed some light and help me fix this horrible WiFi adapter issues I'd fly over and buy him a beer personally!!

Hi Sinvany,

I would suggest you to clean install the drivers by uninstalling the drivers from device manager and reinstalling it and check if it helps:

Download drivers from this Asus link:

http://support.asus.com/download.aspx?SLanguage=en&p=3&s=554&m=ASUS+VivoBook++S451LB&os=&hashedid=latm32feTKbHlUm8

You must be logged on as an administrator to perform these steps.

  1. Open Device Manager by pressing Windows key + X, clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌ If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. In Device Manager, locate the device you want to update, and then double-click the device name.
  3. Click the Driver tab, and then click Uninstall drivers and follow the instructions.
  4. Restart the computer install the downloaded drivers and check.

Follow the suggestion from this link. These steps can help if you can’t connect to Wi-Fi, you have limited connectivity, your connection signal is weak or drops intermittently, or you can’t find a network.

    Hi

    Dealing with same issue, asus laptop windows 8.1 upgrade from windows 8.

    It seems that the TKIP encryption was removed for some reason after the upgrade, changed to wpa2(AES), and works like a charm now.

    Thanks.
