Windows 10: Ethernet keeps dropping internet connection

This has been driving me nuts for months, please help!
I am running Windows 10 Pro (64 bit), up to date, I have a Dell and their software is keeping all drivers up to date too.
I'm trying to use ethernet rather than WiFi for gigabit speeds across my network, however, the LAN connection keeps saying "No internet" after a few hours. I can unplug aand re-plug in the cable and it works again, however I do a lot of work on my home PC remotely so this isn't an option usually.
The built in card is "realtek PCIe GBE family controller" (currently disabled because...) as it wasn't working, I bought a USB3 to LAN adapter, Realtek USB GbE Family controller", this does exactly the same. Both are set to NOT allow Windows to power it off.
I've tried many cables, I'm on a new ISP with a new router, also same on past ISP and 2 routers. I've tried dynamic IP, static IP, google as DNS, auto dns, drivers from the manufacturer etc etc

At the end of last week I updated my BIOS and reset it, this caused Windows to bluescreen on booting, since then I've reset Windows, re-installed all drivers from new and it's still doing the same, I don't know what to do *Sad
Can anyone help?
I've been at it for months looking at other people's posts bit getting nowhere
thanks

:)

No backups maintained?

BIOS update done and reset back to defaults. Now my pc bluescreens (inaccessible boot device) on reboot. Unfortunately i didn't see your reply about it probably not doing anything for the adapter. Gutted. Hope i can get it going.

 

Try uninstalling your Ethernet Drivers? Also check in the Device Manager for the Ethernet device's duplex setting I think its called? Sure someone will jump on and elaborate on this part but try uninstalling the driver and rebooting.

Best to do it with the cable unplugged and plug back in when it says its installed *Smile

 

Cheers, I uninstalled, restarted and re-installed the drivers yesterday (after re-re-downloading them) and again this afternoon, still the same.
Not sure it's the drivers if it's 2 devices doing it (internal and USB3) and they use different drivers.

 

Good point, slap on the wrist for not seeing that bit lol.

Try a different cable pal.

 

Tried numerous cables, currently got a brand new one in, am on my 3rd router since this started happening too *Sad

 

Defo strange,

Try loading safemode with networking and testing there. Pretty much the only thing left that I can think off pal.
