Windows 10: Weird network problems.

Recently, my PC that uses WiFI adapter, started behaving really weird. My usual network speed is 10Mbps,but my PC is not going above 7 anymore. Also, it is extremely unstable. It works in one moment, than drops all the way down to Kbps i guess, for example, if i am playing online game, my ping was always about 20 ms, but sometimes i get huge ping spikes up to 1000 ms, or like huge ping "waves" that goes 200 to 1000 ms over a few minutes. Also, the worst thing is, my other devices like my tablet and smartphone, are practically useless close to PC, their network is ultra slow. But if i go away from my PC, like 5 meters, it is fine... please help. Also, i am a advanced PC user so do not bother with some dumb suggestion. Thanks in advance.

What is this network device?


This is a weird problem I've been seeing in windows for years now (not just windows 10). I've been unable to figure out what it is, but we're not alone in this, I did some research a while back and a lot of other people were seeing it as well.

Some suggest it's a bug in the network stack. Some suggest it's neighbors who are connecting somehow, but not able to use the network. Regardless, it's not an uncommon problem and doesn't seem to be anything worry about. Here's some examples:

Network Adapter PROBLEM

Hi,

Thank you for posting in Microsoft Community.

First Verify if the WLAN service is started and set to automatic, if the WLAN service is stopped, I would suggest you to start the service and put it to automatic.

Step 1: Please follow the steps to
start the WLAN service.

• 
  Click on Start, type in services.msc
  and press Enter.
  
• 
  Select WLAN Autoconfig from the list, Right click
  properties.
  
• 
  Change the startup type to Automatic.
  
• 
  Click on Start button.
  
• 
  Click on Apply, Ok.
  

Restart the computer and verify if it works.

Also check if all the dependencies are also running. Try the steps to check Dependencies.

• 
  Right-click on WLAN Autoconfig and select Properties.
  
• 
  Click on Dependencies, you will find all the dependency services under box labeled this service depends on the following system components.
  

Step 2: Run an inbuilt Network troubleshooter.

• 
  Press Windows + X key and select
  Control Panel.
  
• 
  Type troubleshooting and select troubleshooting.
  
• 
  Click on view all on the left pane and select
  Network adapter.
  
• 
  Follow the on-screen steps and check.

Weird BSOD problem


Hi Everyone,

I have a weird BSOD problem which I cannot solve for a while(it persists still after upgrade to Windows 10 from Windows 7)

The main strange thing about this is that I get BSOD only after cold boot.
So it acts like this:

1. start PC.
2. Get to Windows Logo Screen
3. BSOD
4. Restart
5. Get to menu where I can try to repair or Start NormallyIf I Choose Repair, it will fail to repair and will try to restoreIf I Choose Start Normally, it will start OK, no BSOD, can work normally, games, browse internet, everything is normal.6. Shutdown PC
7. Next time when I start is all over again i.e. Go to Step 1

I have this problem for a while, so what I tried:

1. Another Windows 7
2. Another HDD
3. Only HDD connected
4. Changed RAM
5. Tried with built in GPU
6. Upgraded to Windows 10

Result is the same as above every time.

Please suggest what could be the cause.
Logs collected with DM_Log_Collector, attached.


Thank you

PS. This thread is a continuation of this one: Frequent multiple errors BSOD. Solved - Windows 7 Help Forums the only thing changed is Windows 10 now. instead of Windows 7. If that helps somehow.
