Windows 10: Ethernet only works after reboot (every other time)

Hello! I was having some trouble with my built-in NIC where internet would disconnect randomly, so I went and purchased a dedicated network card. This card does not have the same issue, my connection is stable and does not drop, but it does not work at all the first time I turn on my PC. In other words, whenever I turn on my PC I have to reboot it to get the network card to show up and internet to work. If I do not do that, my network card does not show up in the Device Manager at all. I'm using my wired connection. My Windows 10 Version is: 10.0.19042 Build 19042 My network card is: Gigabit NIC-GX1 I tried the following things without success: Reinstalled the driver for my card several times clean (removed cable, uninstalled driver and device in Safe Mode, installed driver again) both by letting Windows install automatically and using the official driver from the manufacturer's website;Tried another PCI port on my motherboard, though it did not make much sense in the first place since whenever I reboot, my internet connection stays for good;Went back to the store and replaced the network card for a new one, just in case something was wrong with the first one, but again, I'm guessing it would cause issues all the time, not just on first boot;Tried using Windows Troubleshooting. This one failed immediately with errors showing up (screenshots attached below);Tried ipconfig /release and /renew in elevated CMD (screenshots attached below);Used the Windows 10 built in feature "Network Reset";Disabled "Green Ethernet", "Auto Disable Gigabit", "Power Saving Mode", "Wake on magic packet when system..." in the Advanced Properties section in the device manager for this device.Unchecked "Allow the computer to turn off this device to save power" under power management for my network card;Disable the onboard lan in BIOS. Toggling it makes no difference for the issue; When I first boot my PC, the network card does not show up in the device manager at all and the internet icon shows a little globe with a small sign in the right lower corner: Screenshot by Lightshot Screenshot by Lightshot Windows Troubleshooting comes back with these messages: Screenshot by Lightshot Screenshot by Lightshot Screenshot by Lightshot Screenshot by Lightshot Screenshot by Lightshot When I tried the CMD commands, this is what I got: Screenshot by Lightshot Also, if I try to scan for new devices of reinstall the driver from the manufacturers website, it just does not find the device at all, so rebooting is the only fix I've found so far. After I reboot, I get internet connection right from the start, no issues, error messages, nothing in the event viewer or the reliability monitor. The device appears under device manager, and ipconfig /all shows data as expected: Screenshot by Lightshot Screenshot by Lightshot Please let me know if you have any advice on what to try, or if you had a similar issue before and how you got it fixed. Thank you!

New build, all works but ethernet

Anyway everything works fine except for the ethernet port. Under device manager it is listed as "Ethernet Controller", under the category of "unknown devices" (along with several other unknown devices).

 

Domain network ethernet not working but wifi does?

Hi FreeBooter, I already came across this article and followed the steps with no results, I came across other articles that suggested the same steps but still nothing has worked? Thanks for the reply.

 

IP configuration not valid - interference from ethernet adapter?

Solution 1: No Internet Access In Windows 8.1or Windows 10

Step 1:

Go to Device Manager → Network adapters.
Step 2:

Expand it (Network adapters).


Step 3:

Select your network adapter


Step 4:

Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
(in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
Step 5:

Now on a new window you will need to click on “Browse my computer for driver software”.




Step 6:

Then select “Let me pick from a list of device drivers on my computer”.



Step 7:

Now choose the “Manufacturer’s drivers” from the list of two and then click next.



Step 8:

After the completion of the process just restart your PC and check if the problem is solved or not. If not, goto solution 2.



Solution 2: No Internet Access In Windows 8.1,windows10

Step 1:

Open command prompt.
Step 2:

Just go on hitting the enter after typing the each command.
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disable
netsh int tcp set global rss=enabled
Step 3:

Now to check if the settings are disabled type:
netsh int tcp show global
then hit enter.
Step 4:

Now the thing left is just rebooting your system and just check if the problem is solved or not and just give feedback.*chuckle*Thumbs
