Windows 8.1: WiFi dropping and/or "Limited"

Mine uses a Qualcomm Atheros AR9485WB-EG adapter. I've downloaded the driver version 10.0.0.276 dated 12/12/2013. No better.

It's clear that Microsoft is responsible for this. Whatever changed between 8 and 8.1 and whatever subsequent fix was applied has broken connectivity (it worked fine until a few days ago on 8.1).

Microsoft have, as usual, blamed the wifi card suppliers, but Microsoft ought to take responsibility themselves because this happened when THEY applied THEIR updates to my operating system.

I'm only able to use my laptop when connected directly to my router. What the **** is the use of that?

PS No response at all from Sony - but they're dropping the VAIO, so I suppose I shouldn't be surprised!

Mine is Thinkpad E440 with Windows 8.1 and Intel Wireless N 7260 having disconnect and limited connection issue. 

Yesterday i realized that Wifi driver from intel is released with version 17.0.2.5 which is in the update description is fixed the disconnection issues. 

I reinstall my Laptop with Windows 8.1 and install the latest driver for Wifi to 17.0.2.5 from Lenovo site and my problem is solved! I have posted many questions in Intel and Lenovo forums and finally Intel and Lenovo support solved this problem.

I got 2 days stable connection after fresh install of Windows 8.1 with the latest driver and hopefully for the future. Will keep you posted. 

Thanks!

OH! Very Thanx!!! I have solve same problem on Lenovo Flex 15 IdealPad with Windows 8.1 x64 by reinstalling LATEST (17.0.2.5) version of Intel Wireless N 7260 driver! Thank you alot!

I have this problem too - just started happening with Windows 8.1. Last year I was "blackmailed" by Microsoft to "resolve" another problem. Paid their £99 and, after hours of fiddling was told they couldn't fix it, just had to reinstall the original OS!

Their "support" is absolutely DREADFUL. This problem is NOT a router problem (we've another 2 Windows 7 machines, 2 iPhones and 2 iPads connecting perfectly). It is a Microsoft bug.

The really annoying thing is their condescending attitude. I've got over 40 years IT experience. I've written 4 successful software products and actually know how to program, yet they keep trying to tell me I need to be "qualified" and "trained" by them. Perhaps they should be a bit humble and pay me to train them!
