Question No Network on Cold Boot

[FarmerFran]

When cold start my pc and log in I get no network.
If I just restart it is fine. This started maybe a few days ago after owning PC since early 2020

Win10
Gigabyte Z490 Aorus Master

Instead of restarting look at the ethernet port with IPCONFIG /all

I suspect it will have a 169.x.x.x ip address.

Try ipconfig /release
ipconfig /renew.

If this work it is likely some strange delay issue with the dhcp function from the router. You can hide that problem by assigning a static ip to the ethernet port.

says cannot release when not connected (I cannot remember exact wording).

All I do is restart, nothing else and it fixes it. Really weird.

It is strange if the port is in a disconnected state. That is generally a hardware thing.
Check the bios and see if there are any of those stupid green energy things set.

Does it fix it if you do something simple like unplug and replug in the ethernet cable.

No, I tried that and the "MS repair says plug in the cable" Let me 2x check the BIOS

Is this an add-in NIC, USB NIC, or are you using the NIC from the motherboard?
Has Windows updates (or other driver updates) been done recently?
Check NIC power management in device management.
Try a different network cable.
If the NIC light (on motherboard) on while the computer is off?
When you cold start the computer does the NIC light light up during the POST or Windows boot process?
Try switching the cable to a different port on your router.

Run "ipconfig /all" again and post the results.

You should be able to copy and paste the results without needing to retype everything.

Do so first, immediately after boot, when when "no network" occurs.

Then again after the reboot and the network reappears.

Compare the results.

It says no network so it reports no information - I cannot remember the exact wording. After the reboot it reports all the information correctly.

On-board. Tried the cable, ports, resets etc...

I am going to revert the drivers and hope that was it.

EDIT: Switch was flashing, motherboard was not.

It turns out Gigabyte has a new driver posted 1-7-2022. I installed that, so we shall see.

It was not on the site on the 7th and not sure when they actually added it.

EDIT: Did not work

It's a stretch, but I've seen issues with slight power surges/brownouts on the same circuit (UPS/PDU/surge protector/outlet) causing weird issues. Try maybe moving the router to a different outlet??
Have you tried a different router? -or- can you take your router out of the equation and plug directly into the modem?

Also, remove the gigabyte driver completely and see if Windows 10 has a generic driver for it.

And still post the results of "ipconfig /all". Something may be astray within the results.

Have you tried disabling IPv6?
