New PC Keeps Losing Wifi Connection

Hi there

I bought myself a nice new PC at the end of last year; but I'm having big problems with the wifi suddenly cutting out, for no apparent reason. All of a sudden, I get a red X on the wifi symbol in the bottom right of the screen; when I click on it to look for available networks there are none listed - not my router, or any of the neighbours - and yet other devices, like my phone are still connected to the hub - which is still on and seems to be working perfectly.

If you click on "network settings" and look and try to go to "adapter settings", sometimes it will let you - but sometimes you can't even do that. I have a network card in the machine that I thought might be causing the problem, and on the occasions that i have been able to get into the adapter settings after it's happened, it won't let you "re-enable" the network card. I have tried added a wireless dongle to the USB port, and sometimes it will let you connect again via that, but eventually the same thing will happen again - it will randomly cut out when you're in the middle of doing something.

If you try to restart, it just hangs - and the only way to get back online is to hold in the on/off power button for a few seconds, and then turn it back on again.

I've tried changing the internet channel on the router; i've tried reinstalling the drivers for the network card; i've checked for clashes between Malwarebytes and Avast; I've changed the properties on the network card and the dongle to not allow them to turn off for power management reasons; and none of these seem to work.

Would anyone have any ideas? I'm running Windows 10, on an Intel Core i5 6500 s1151 3.2GH.

Thanks in advance for any suggestions!

The only thing I see that looks funny is the first DNS server which appears to be on the wrong network:

 

Networking Dns Servers: 192.168.0.9
192.168.1.254

 

 

Did you manually set your DNS addresses?

 

Have you had Avast run a boot-time scan to rule out an infection of some kind?

 

 
Open Avast, Scan, Scan for Viruses, Change the Quick Scan (in the box in the center of the page) to Boot-time Scan.  Then at the bottom of the page click on Scan Settings.
Set Areas to Scan: to All Harddisks
Make sure both boxes are checked and click on the gray box to the right of the orange ones.  It should turn orange.  Change where it says "Fix Automatically" to "Move to
Chest."  OK.  Now click on Start and then close Avast.  Mute your speakers so it doesn't wake you up when Windows boots.
 
When you reboot you will see the scan start.  It will tell you where it saves its log.  Usually it's C:\ProgramData\AVAST Software\Avast\report\aswBoot.txt but it might change so verify the location.   This is a hidden location so you will need to tell Windows to let you see it:
 
 
Copy and paste the text from the log to a Reply when done.
 
Let's check your system files to amke sure everything is OK:
 
Open an elevated command prompt:
 
 
 
If you open an elevated command prompt it will by default open in c:\Windows\system32
 
Once you have an elevated command prompt:
 
Type(with an Enter after each line):
 DISM  /Online  /Cleanup-Image  /RestoreHealth
 
 (I use two spaces so you can be sure to see where one space goes.)
This will take a while to complete.  Once the prompt returns:
 
Reboot.  Open an elevated Command Prompt again and type (with an Enter after the line):
 
sfc  /scannow
 
 
 
This will also take a few minutes.  
 
When it finishes it will say one of the following:
 
Windows did not find any integrity violations (a good thing)
Windows Resource Protection found corrupt files and repaired them (a good thing)
Windows Resource Protection found corrupt files but was unable to fix some (or all) of them (not a good thing)
 
If you get the last result then type:
 
findstr  /c:"[SR]"  \windows\logs\cbs\cbs.log  >  \junk.txt 
 
Hit Enter.  Then type::
 
 
notepad  \junk.txt 
 
Hit Enter. 
 
 Copy the text from notepad and paste it into a reply.
 
 
After you finish SFC, regardless of the result:
 
 
 
1. Please download the Event Viewer Tool by Vino Rosso
and save it to your Desktop:
2. Right-click VEW.exe and Run AS Administrator
3. Under 'Select log to query', select:
 
* System
4. Under 'Select type to list', select:
* Error
* Warning
 
 
Then use the 'Number of events' as follows:
 
 
1. Click the radio button for 'Number of events'
Type 20 in the 1 to 20 box
Then click the Run button.
Notepad will open with the output log.
 
 
Please post the Output log in your next reply then repeat but select Application.  (Each time you run VEW it overwrites the log so copy the first one to a Reply or rename it before running it a second time.)
 
Let's look at your system and see if there are any obvious problems:
 
 
Get the free version of Speccy:
 
http://www.filehippo...download_speccy (Look in the upper right for the Download
Latest Version button  - Do NOT press the large Start Download button on the upper left!)  
Download, Save and Install it.  Tell it you do not need CCLEANER.    Run Speccy.  When it finishes (the little icon in the bottom left will stop moving), 
File, Save as Text File,  (to your desktop) note the name it gives. OK.  Open the file in notepad and delete the line that gives the serial number of your Operating System.  
(It will be near the top about 10 lines down.) Save the file.  Attach the file to your next post.  (More Reply Options, Choose File, Open, Attach This File)
