Windows 8.1: WiFi dropping and/or "Limited"

I have decided to join this discussion as it was my first port of call when I experienced this issue which started last weekend after upgrading to Windows 8.1.  My network adapter is a Netgear N300 (WNA3100).

I tried every single option on the net practically plus advice from someone on the Microsoft forums but whilst a lot of ideas worked to start with within a couple of hours maximum the issue would return. 

The only thing that reconnected would be to unplug the adapter from itself then reconnect but this of course isn't a fix rather than an annoying reset.

Then I came across this site http://pureinfotech.com/2013/09/16/how-to-fix-wireless-limited-connectivity-windows-81/

I tried the first options but again only a temporary fix.  However I then tried the bottom option which is :

Update: If after trying all of the above solutions, you still having Limited Connectivity problems, changing the following network settings could also help.

Note: Apparently the following changes works best for Surface RT devices. However, you can try this solution on any Windows 8.1 PC, including Surface Pro.

1 Open the Command Prompt as administrator (refer to previous steps).

2 Next, type the following commands (one at a time) press Enter and OK on each one:

netsh int tcp set heuristics disabled

netsh int tcp set global autotuninglevel=disabled

netsh int tcp set global rss=enabled

Then use the following command to verify all the previous settings are disabled:

netsh int tcp show global

3 Restart your device and see try to connect to your network.

It's now been around 15 hours and the connection hasn't been disconnected or become limited once and I have tried rebooting a couple of times and waking the PC from a sleep and all seems well.

Therefore I thought I would post this as it may help others with the same issue.

One thing is though I have absolutely no idea though what I have actually performed here but thought it was time to throw caution to the wind so if anyone has time to explain what the steps may have done I would appreciate it.

I had a similar problem with my Lenovo ThinkPad running Windows 8.1.   LenovoERMDiscovery process was running automatically transmitting large amounts of data to the network.  Once I stopped the service everything was fine.  Hope this helps.

Two Windows 7 machines, 2 Apple iPods, 1 Apple iPhone and 1Blackberry all connect fine to my home wireless network.  Windows 8.1 DellXPS12 often loses the connection, shows limited connection.  Microsoft: Time to spend some time and money on a solution or better diagnostics to identify the problem.

Similar happening to me, 2 cheap Chinese Android phones, IPhone 4,  Sony Vaio with Win 7 are working perfectly with Apple Wireless Router and before with Asus N16 Router, but my Asus Zenbook with Win 8.1 constantly lose connection, especially when I play in COH2.

Hi,

Limited connection means the PC has successfully connected to the router, but the PC wasn't assigned a valid IP address, so you can't actually get to the Internet. It can also indicate that a valid IP address was assigned but that the PC doesn't have Internet connectivity. If you're connected to a home network, try restarting the router.

However Internet connection problems are most commonly caused by disconnected cables or by routers and modems that aren't working correctly.

Try these steps:

Run Ipconfig /all at the command prompt to check if you are able to obtain an IP (internet protocol) address.

a.Go to Start screen type command prompt select command prompt as an Administrator.

 b.Click ‘OK’ to open a MS-DOS command line window.

c. Type "ipconfig /all" (without the quotation marks), and then hit the**‘ENTER’** key.

Why can't I connect to the Internet?

Please revert with the issue status.

Okay, now that several months have passed since the 8.1 update and everyone's routers have been checked and the cables are secure, what is the solution to this problem as it still persists?!

Yeah! Real people want to know.
