Windows 8.1: WiFi dropping and/or "Limited"

"...At that time I will open a new Question thread... as long as the connection remains 'stable' I see no reason to 'fix' what ain't broken.... YKWIM?"

Did you do it:

CMD Admin

pnputil.exe -e

look wifi card OEM#

pnputil.exe -d Oem#.inf

After download Only oryginal driver (wifi card) (not aplication) 

and instal manual in device manager.

If want or not sure, can delete all Oem#.inf

I didn't see an open question asked by you. It is better to open a new thread.

If you can connect but it then drops and a manually disconnect and reconnect solves the issue do this

press windows key + X > device manager > expand network adapters > double click the wireless one > power management tab > uncheck allow windows to turn off this device to save power.

This will prevent windows from sending out notice it can sleep.

Next press windows key + x > command prompt > type these commands and press enter after each one

ipconfig /flushdns

ipconfig /release

ipconfig /renew

if you get a message that there is no adapter or something similar let me know. When you get a chance to open a new question post this info in the question. To copy the info right click the command prompt and choose select all then press enter. This will copy the output of the command prompt

 I would need the output from these two commands

ipconfig /all

and

netsh wlan show networks mode=BSSID

I've already applied the 'power management' fix you suggested above.....

Last night I tried a 'fix' that another user on this Forum suggested and so far I've had no connectivity ILimited connectivity or drops) issues whatsoever... I uninstalled Chrome and re-installed it, but DID NOT sign in to Chrome.... so far, so good. 

The next time I lose connectivity, I will run the ipconfig and netsh commands that you suggested above and import the command results for you to evaluate. At that time I will open a new Question thread... as long as the connection remains 'stable' I see no reason to 'fix' what ain't broken.... YKWIM? 

So far, this particular 'thread' on this Subject has been the most useful for me.... so, that's saying alot..... :)

CMD Admin

pnputil.exe -e

look wifi card OEM#

pnputil.exe -d Oem#.inf

Alternative:

CMD Admin

driverquery.exe 

/?

After download Only oryginal driver (wifi card)

and instal manualu in device manager

If it not working, it is hardware or BIOS power managment problem.

You are referring to an API used by third party driver makers https://msdn.microsoft.com/en-us/library/windows/desktop/ms706593(v=vs.85).aspx which was replaced by https://msdn.microsoft.com/en-us/library/windows/desktop/ms706275(v=vs.85).aspx is for devolopers as part of WDF.

You have hit the head on the nail. Windows provides the tools for the vendors to make a driver that works with Windows. How ever, like many programs there are bugs and programmers don't always get it right the first time.

This is what my point is. Windows doesn't program these drivers the third party companies do. They are responsible for making, supporting and providing updates to the driver. That is why telling Microsoft to fix it will never work. They can't fix what they don't make. Telling the PC vendor they have a broken WNIC and not accepting its Windows fault will force them to get these issue fixed.

Often their stuff works but the router has old firmware that doesn't support certain security or handles security in a way that causes the wireless connection to break. By telling the correct person you start a chain or communication that can get the issue fixed.

Most of these issues were fixed already but since people don't always get an update to a router or other hardware a small amount of people will continue to get issues. Here is an example of an issue that was cause as a result of Windows 8 causing an issue. It was an issue that was always present but due to upgrades in security it wasn't caught until 8 was released http://support.microsoft.com/en-us/kb/2749073

This is what I am trying to convey so these issue are fixed. The way it works is Windows makes the OS. The vendor must provide support for windows and their PC for a year. In this year they can contact all of their hardware vendors and Microsoft to discover the issues and repair the issue.

In a perfect world Microsoft could collect information from your computer and send the data collection to the vendors and force them to fix the issue. However due to privacy laws and other factors they can't collect data in this matter and send it off.

Good luck I will look for your question and be happy to help you
