Hey all. Got the rest of my new components yesterday and finished my new build. MSI Z790 MAG Tomahawk DDR5, 13600k, Corsair Dominator DDR5-5600, Samsung 990 Pro NVME, RTX 4070 ti. For the most part everything went OK but I have had issues with the LAN port on the new MOBO and I am really baffled by this. I was wondering if anyone might be able to provide insight. Here goes:
When I first powered up the new machine yesterday I saw the lights on the LAN working. Then when I started the Windows 11 install they went away and wouldn't come back. No ethernet connection even though I KNEW it was working. I literally spent hours troubleshooting. I basically threw the book at it, re-installed the drivers from MSI website several times, changed network settings, uninstalled the drivers and shut down the PC, performed a network reset both from within Win11 and a winsock reset from cmd, cleared CMOS, etc etc. I even chatted with MSI tech support and they had me try some things. NOTHING WORKED. Then I shut down the PC overnight and when I turned it on today, the LAN port worked and I had ethernet connection. WTF! I didn't even do anything other than shut it down. It was the first time I actually had a hard wired ethernet connection on this machine. After that I reset the PC and went into BIOS to enable XMP for my RAM and OC the i5 (slightly), when I exited BIOS and back into windows, LAN port was down again. So I again SHUT DOWN the PC (not a reset, a shut down), and actually unplugged the power cable for a few seconds and then plugged it back in and started it back up...LAN port working again. I actually went though this cycle twice to confirm. It appears that even if I enter the BIOS (and not even make any changes) and then exit to windows, the LAN port doesn't work. It will then work again only if I shut down the machine (a reset won't do it). Any ideas on this one? I have obviously googled this and read that there are known stability issues with the latest Intel network driver that I am using, is that what I chalk this up to and just live with it (for now)?
