Windows 8.1: WiFi dropping and/or "Limited"

I've just been on a web chat with a Tech from Acer.

I asked the question about disabling iPv6 and he wouldn't commit one way or the other.

He asked me for my serial number and sent me a link to What he said was the latest driver for my  Intel Centrino wireless-N 105 adapter.

When I looked at what he had sent it is a  Wireless LAN_Atheros_10.0.0.263_W81x64_A.zip

Question is would this be compatible with the Intel adapter?

Really confused now!

Have you tried the solution that worked for me by disabling IPv6 and making a change in the power management. Brad that posted the solution had an Asus, so hopefully it will work. I have copied the post below.

I had the same problem with my new ASUS laptop. I fixed it by going into network settings-adapter settings and unclicking "ipv6" then going into power management for the adapter and unclicking "allow computer to turn this device off to save power." Problem solved.

I tried to add screen shots but message came up as too long

But fairly simple

Click Change adapter settings in Network and sharing Center and clear tick by IPv6

Then:-

You can use Device Manager to change the power management settings for a network adapter. To disable this setting in Device Manager, expand Network Adapters, right-click the adapter, click Properties, click the Power Management tab, and then clear the Allow the computer to turn off this device to save power check box.

Qualcomm Atheros AR9485WB-EG is definitely UNSTABLE in my Asus s300CA with the latest 8.1 update.

Additionally, the wireless connection is retarted as 5-8mins...???

and every wifi signal is ticked as "connect automatically" although I didn't do anything like this as you can easily guess... ?

My driver version is 10.0.0.263 dated 15-Aug-2013 !

What's going on windows...???

I'm seeing the same issues using a Qualcomm Atheros AR9485. Tried all of the above as well as switching to the most recent qualcomm distro of drivers (rather than what microsoft gives by default)... I've gotten my stability up from a dropping every 15 minutes to about once every 2 hours. Better, but it's still causing a lot of problems.

I depend on VPN and tunneling for work and every time this happens my tunnels drop and my VPN can get wonky. This is costing me significant time and money - if anybody has any other suggestions or a fix with the above card, please let me know.

P.S. Microsoft has really damaged any faith I had with them. Constant hounding to upgrade to their poorly QA'ed pos OS with no reliable way of going back. As a quality engineer myself it frustrates the **** out of me. I already have to use Linux for work... maybe it will become my home OS as well.

The problem came back.  I tried uninstalling the Centrino Advanced-N 6235 driver and re-installing Wireless_16.5.3_e164.exe, but that didn't help.

Meanwhile, for the work that I do that requires a stable network connection, I will need to tether to my LTE iPhone 5s until someone finds a solution.

I am very disappointed that Microsoft introduced this problem in Windows 8.1 that was not in 8.  Small point-release Windows upgrades didn't used to introduce regressions like a network driver dropping its connection.  No wonder almost all of my co-workers have switched to Mac...for their work machine.

It is a problem with your Intel WiFi card, look back to previous posts about it, the issue with Windows 8.1 is complementary to the Intel card.
