Windows 8.1: WiFi dropping and/or "Limited"

I did what you recommend here about a month ago and it seemed to help then the problem started again. My internet provider gave me a new modem and everything worked fine again. Well, the problem is back and I could not stay on the internet long enough to change one page.  I ran across your post and decided to give it another try. Mine was already unchecked. However I noticed under the "sharing" tab it now had "Allow other network users to control or disable the shared internet connection"  checked. I unchecked that and my internet/computer are working great again. I am the only person in the household using this computer and have no idea how that ever got checked.

Limited connection means the connection is not working. It could be a hundred different reasons. It is like a car not starting, that just means its broke.

Sometimes its the ISP, bad router data, bad drivers, bad config data.

In your case a switch in networks could have got you new config data from the router which was the issue. Or it may have reset a profile.

Any time someone has a issue with their PC and they need to ask a question the question should be asked on a new thread. It is too hard to troubleshoot not knowing what was done.

One strage thing that has helped for me on 2 separate occasions where wifi connection at home on my home wifi network (Asus RT-AC66U) got unstable:

I just connected my Dell Inspiron Win 8.1 to another wifi network. I don't understand why or how, but this action seemed to stabilize the unacceptably unstable connections each time. First time, it got unstable again due to driver updates, second time is still stable, having tried and rolled back the driver a few times to the last stable that worked for me... I'm btw running 8.1 on a Intel(R) Dual Band Wireless-AC 7260. Latest Intel drivers do not work OK, I've rolled back to driver version 17.0.5.8 as of 2014-06-18 a couple of times...

NO driver updates, NO config changes to stack, OS or whatever - JUST connected to another wifi network and back again and then it had become stable.

(It should also be noted, that all other devices incl a Win 8 laptop are OK - AND that I've tried all tips&tricks seen around here, on tweaking to stabilize Win 8.1 - without luck...)

Actually, it looks like I solved this problem. I reinstalled Windows 8.1 with the recovery partition on my computer (hp touchsmart 14) and while making this, the system deleted all of the former drivers, dns caches...etc (actually the computer has been formatted completely) and after this reinstall process, I did nothing about the wifi driver. I just update windows 8 to windows 8.1 and install some of my computer programs (Office, Visual Studio, MATLAB, COMSOL, SolidWorks). Action center shows me a message that Wifi and bluetooth adapters should be reinstalled but I also didn't do that. In addition to this, before this reinstall process I was using static DNS (I was using Google DNS) but I saw in some forums that changing DNS may also cause this problem. That's why I'm not using any specific DNS now. It's automatically selected by my router or computer (not sure). Also, I checked the version number of my driver that it's not the last update (my wifi driver is Intel 7260N, driver version: 16.10.0.5). 

So now, I haven't encountered any problems for 5 days. Before all of this process I was facing with this problem several times in a day. In addition, according to some forum posts, there may be some conflict between WiFi driver and bluetooth driver that's why switch off my bluetooth device before reinstall process. However now, my bluetooth device is open all with my wifi driver and even this there is no any corruption, speed decrease...etc. That's why I recommend you to reinstall your windows 8.1 and do nothing about the wifi driver.

I hope, it would work:) (sorry for grammar mistakes)

It seems there are a multitude of issues depending upon which wireless adapter your W8.1 machine contains.  My Toshiba Satellite L series laptop has an Atheros AR956x adapter.  I originally got some relief from slow/intermittent wifi connections by going back to a previous (older version) driver.  However, the wifi issue resurfaced again after I discovered that Windows was automatically updating my adapter's driver to a newer version, which I didn't want to happen.  I disabled the automatic updating of the driver, but the problem kept coming back.  Oddly enough I decided to change the settings on my router to standard channel vs wide channel (2.4ghz) and I haven't had any further issues, no matter what driver is installed.  Weird, but it seems my Atheros adapter doesn't like a wide channel signal!  :-)
