Question Internet disconnecting for a few seconds randomly

[Linally]

Good evening!

I have been having this issue for some time now, but lately it has gotten somewhat worse.

Sometimes my internet will randomly disconnect for a few seconds before reconnecting (I am using ethernet cable and my router is a Huawei HG8546M and a Netgear GS108 switch)
It happens much more frequently when I am playing games and much less often when I am working/doing other stuff on the pc. It also happens only on the one pc, with 3 other PCs on the same router working perfectlly. I have tried powering off the router for a few minutes, I have switched to a new ethernet cable and I have upgraded my drivers to the latest version but the problem still persists

I have a USB wifi adapter and when the ethernet internet disconnects I have noticed that I also cannot connect to any available wifi network.

Is it a mobo issue? Is it software related?

Update your post to include full system hardware specs and OS information.

This:

"I am using ethernet cable"

and

"I have a USB wifi adapter "

On that one pc do you have both a wired network adapter and a wireless network adapter enabled?

Only one or the other should be enabled. Only one network adapter should be enabled.

Run "ipconfig /all" (without quotes) via the Command Prompt. Post the results.

I see your point
On that one pc I have the embedded ethernet adapter and the USB wireless network adapter enabled. I use the wireless adapter mainly for printing stuff on a printer which is connected to a different network, and mainly use the ethernet adapter. I have used this configuration for about 2 years, and the disconnection issue first started appearing about 3 months ago. I gather I should only connect the USB adapter when I want to use it and remove it afterwards, but the disconnects happen regardless of whether the USB adapter is plugged in or not.


This is the ipconfig /all result and I am updating the full system specs in a while (PC runs Windows 10 Pro v. 21H1)

Provided that I am following correctly you must disable which ever network adapter is not being used and enable the network adapter to be used.

Then do a restart.

And all the more so if there are two different networks involved.

Windows must be properly configured for the destination network be that network wired or wireless.

I have disabled all network adapters except from the Ethernet which is the one I am using, restarted the PC and done a network reset from windows, but the issue still persists.
I might be mistaken, but I believe that it now occurs much less often than it did before, so I will try disabling the VPN virtual adapters and see if the issue is there

So, I finally fixed the problem after many attempts.

What I found out is this: I used to have Surfshark VPN installed. A few months ago I uninstalled it completely (supposedly) and started using Express VPN since I got it for free from work.

Apparently the TAP for Surfshark while removed from every place it was supposed to be was for some reason not uninstalled completely, and would create a conflict that made my ethernet adapter go haywire every once in a while. I completely removed it and haven't had the problem occur since. If it happens again I will update.
