I wouldn’t call running a 2.5GB NIC at 100Mb a fix. The easiest fix is just to disable it in the BIOS and spend £10 on a USB NIC that works as advertised 100% of the time without changing any settings. Both Intel and ASUS know about the problem and are doing nothing to address it, I’m surprised a class action has not kicked off.Might be worth trying this, someone with a Asus B650E-I Motherboard fixed it by following the same steps in this video below >> https://www.reddit.com/r/ASUS/comments/15e5bvf/rog_strix_b650ei_motherboard_ethernet_not_working/
