Windows 7: Network Connections Constantly Crashing, Need Help!

Network Connections Constantly Crashing, Need Help!

So recently I've been having network issues. It started when I realized that my Network Adapters were not showing in the Network Connections folder, despite being in the device manager and working correctly. I tried every solution on the net to fix this, and nothing seems to work. However, I think I've located the core of the problem and I was wondering if you could help.

This screen shot is from the Action Center Recent Problems page or whatever its called:

Checking for solution provides no help.

However, this shows that the network connections is literally failing every minute. Which I think is the root cause of my main issue. If anyone has any idea how to solve this, Id love some help.

Another screenshot here shows the details of the crashes:

I believe all are the same.

Start with running cmd as admin:
Code:
sfc /scannow
If corruption is found, run this in cmd too and attach the sfcdetails.txt (check desktop) here:
Code:
findstr /c:"[SR]" %windir%\logs\cbs\cbs.log >"%userprofile%\desktop\sfcdetails.txt"

Hi, GokAy

I performed the sfc scan and it says corruption was found. However Im having trouble carrying out the second operation. I assume im supposed to replace the "[SR]" and %userprofile% and maybe remove the quotations, but im not entirely sure. could you clarify please

I am not sure if your issue is related to that one corruption. But searching for dot3api.dll show it is related to 802.3 and
Quote:
IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer's media access control (MAC) of wired Ethernet. This is generally a local area network technology with some wide area network applications.
So likely it is, I will PM our expert on this issue once CBS.zip is uploaded. But also need you to attach CBS.log as described in Windows Update Posting Instructions #4 (log collection).

That does sound like a problem, considering im using ethernet to connect to a TP-Link adapter which then connects to my router via the mains, I think. So this could definitely be the problem. I appreciate the help and your patience so far, GokAy.

The zip file created is 33.9MB, which I think is too large to upload, as the max seems to be 8MB. What should I do?

You can upload to a cloud sharing site; OneDrive or Dropbox works. I guess there is a way to reduce the size but I couldn't be sure:

simply delete the oldest CBSPersist files
If it doesn't help, just upload to cloud as I said.

Ok, I deleted some CBSPersist files from a few days ago, and kept one from earlier today and the log of course. Here is the file:
