Windows 8.1: WiFi dropping and/or "Limited"

I've tried so many different things to fix this and nothing worked. I've adjusted power settings, installed different versions of the drivers, all to no avail. I finally found a link to a Dell support page (even though my computer isn't a Dell) that recommended disabling some of the TCP settings via the command line. This, so far, has resolved the problem for me. Here's hoping it can help someone else as well. 

"Another good fix to address the issue is to disable the TCP settings. Do the following:

• Open command prompt with administrative rights
• Type the following commands and hit enter after each command:
• netsh int tcp set heuristics disabled
• netsh int tcp set global autotuninglevel=disabled
• netsh int tcp set global rss=enabled
• To verify that these settings are disabled, type

netsh int tcp show global and hit enter

Once done, you are advised to reboot your system. This should resolve the problem"

This was only a 'temporary fix' for my Toshiba S55-A5139 

Shortly after applying this 'fix' my WiFi resumed LIMITED Connectivity again.... so I don't know about others, but this isn't what finally fixed my connectivity issues permanently.

I had the same problem with my new (Jan.'15) Dell laptop running Windows 8.1. I tried all the fixes I could find with no luck. Then out of sheer frustration I tried this:

I went to....Control Panel> Network and Internet> Network and Sharing Center. Then I clicked on "Change adapter settings" on the left side of the screen. It the showed my Wifi connection plus "Bluetooth Network Connection". I never use Bluetooth, so I right clicked it, then clicked "Disable". No more "limited access" problem! Hopefully this will solve someone else's limited access issue who hasn't had any luck with all the other fixes.

Hope this helps: https://www.youtube.com/watch?v=xGd7EgyWYZs

You should re-read my post. I was giving you advice about what to add when telling people to downgrade their windows 8 to windows 7. You misunderstood everything I said. It isn't polite to give people advice based off emotion or pure guess work. Nor is it fair to give advice that can cause catastrophic effects without advising them of all potential outcomes.

You said  "I'm actively 'researching' and 'working' towards finding a Permanent FIX for ALL of the People who are experiencing WiFi Connectivity Issues on their Windows 8 and 8.1 systems... so do your 'research' and realize this IS a Software Problem and Micro Soft has been UNIVERSALLY found at fault."

I have researched many fixes. I am not sure why you adopted my advise for you to first suggest downgrading the driver as the only fix in the world. However, that method is advantageous to a OS overwrite since it is a few seconds of work before suggesting downgrading an entire OS. 

If you would like to have a discussion on what can be done to fix a limited connection feel free to start a discussion and we can talk. I am not sure what field of programming you practice or in what field of IT you work in. If you would like to elaborate, the conversation could be more pointed toward the experience level you are at and the field in which you practice.

Here is a good resource you can use to fulfill your quest to find a universal fix -- in case you don't already know about driver programming -- it may give you more understanding about drivers https://code.msdn.microsoft.com/windowshardware/site/search?f%5B0%5D.Type=Topic&f%5B0%5D.Value=Networking.

Also helpful is to understand where there is abstraction and inheritance between the many drivers there are to run a single device. Networking, especially wireless, has a huge N-Tier architecture https://msdn.microsoft.com/en-us/library/windows/hardware/ff564862(v=vs.85).aspx#possible_driver_layers 

Here is a link to the WiFi alliance which has useful information about certified devices and standards that are developed and should be adhered to for consistent connectivity http://www.wi-fi.org/  

I'm going to repeat this one more time only...... I don't have a WiFi Connectivity Issue anymore, because "I" fixed it (after many LOOOOOONG grueling months)....
