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.

    Switch you router to 802.11g mode only.

    I was actually on a different router yesterday that was G mode only and the problem presented itself worse than normal.  It was going offline every 15 minutes or so.  Everything else connected to the router was fine.  

    I don't think changing my home router to g mode only is going to fix the problem, plus it sounds like a band aid fix to something that's going on with the adapter and/or Windows.

    I have the same experience.

    Qualcomm Atheros AR9485WB-EG Wireless Network Adapter in my Sony notebook.

    I had no problems with Windows 8, but after Windows 8.1 update I have problems connecting to my home wifi. There are 10 other devices, windows vista, xp, android phones, tablets with no problems at all.

    I have the latest DriverVer   = 08/15/2013,10.0.0.263

    Tried to install, roll back to previous versions, tune  netsh settings, but with no success. As I can read on other forums this problem is quite common and no one successfully identified the problem yet.

    I can not read event viewer logs because since 8.1 it is flooded with DistributedCOM 10016 Errors

    I regret the moment I installed 8.1  . . .

    I have the same issue with the same wireless adapter (AR9485WB-EG) and it only started after I updated to Windows 8.1

    My flatmate's laptop (which is has the same wireless adapter but is still on Windows 8) doesn't have the same problem and neither do our smartphones (so it isn't our router). I also didn't have this problem with the same laptop under Windows 8.

    None of the methods given to solve the issue given in this post have worked out for me.
