Chosen Solution
I just bought a new motherboard because i was having some major issues with my last one. It unfortunately didn’t come with the driver disk. But i was able to get it all online and its updated. But now im having this issue where i get the error “Ethernet doesnt have a valid IP configuration” At first it woulnt’t even show it was plugged in till i changed “auto disable gigabit” to “relink, battery or ac” and disabled both “Energy efficient Ethernet” and “green Ethernet” Iv tried the following to fix the problem: Disabled/enabled Unchecked “turn on fast start up” Entered in IP and DNS myself Uninstalled and reinstalled driver Restarted the router disabled IPv6 unplugged pc and hit power button for 30 seconds reset windows 10 with keep files (these worked for about ad hour after then went right back) Command prompts netsh winsock resetnetsh int ip resetipconfig /releaseipconfig /flushdnsipconfig /renew I tried to stop/restart DHCP client but i get an error (Error 5: Access is denied) and i run is as admin There are times some of these will work but then it will go right back to no ip config. Iv tried searching the internet for other solutions but these are all the solutions i get but none have worked. The network driver is Realtek PCIe GbE Family Controller
Hi @darkstorm824 , Just wondering if you have any cards installed in the PCIEx1_1 slot (the one closest to the CPU)? This slot shares an IRQ with the LAN controller so maybe if there was one installed, there may be a conflict occurring. See Sect 1.5.2 on p.1-10 in the user manual about assigning IRQs etc if the card has to be there. Also perhaps try installing this unofficial Win 10 driver for the adapter, (scan it first just to be safe). It is looking like a compatibility problem and hopefully not a faulty LAN controller which would be unusual given that it’s a new motherboard. (or it it just new to you?)
