My LAN connection quit out of the blue, wifi is fine. Well i was getting hammered by a shady cloudfare address (or rather something was hammering an outbound to it) Autofix says "Ethernet" doesn't have a valid IP configuration. I can't even connect to either router. Lights and pins on port of mobo (and others) fine. While trouble shooting,;I came across a step suggesting manually assigning the MAC address - but the option seems to be missing from the advanced tab in properties. It doesn't seem to exist anywhere in gui, tho I could find the address itself easily enough from command line.
I've tried everything else, cables, ports, driver reinstall, ipv6 disable, powering down for a while - everything up to DHCP on this page https://windowsreport.com/ethernet-valid-ip-configuration-windows-10/
I'm gong to try that now but not hopeful. Any help would be appreciated.

Realtek gigabit onboard ethernet intel l218v
Isp: bell Canada 50mbps, home hub 3000 (sagemcom 5566)
Evga 650 g3
Only wired connection, tried others of 5 ports, all wifi works well. Nothing networked.
Thanks
UPDATE: So when trying to restart the DHCP client from services, whether run as admin or not, I get "Windows could not restart the DHCP client on this computer, error 5: access denied - even though mine is the admin and only account on the computer..
The most unusual thing is; The Network settings Physical MAC address function is missing - I feel this is likely telling?
EDIT: Connected a different computer to modem/router, works perfectly.
FINAL EDIT: system restore... In my defense I had it turned off for years, welp time for drive tearing malware n virus sweeps!
