Essential details to remember are that speeds above 100mbps were observed. Understanding how to restart Ubuntu or comparable systems from a USB drive could help determine if audio and LAN issues stem from hardware or software problems. This method won’t alter your current Windows setup.
I’m ready to give it a shot! I think I’ll install the software via USB and launch it through the BIOS.
I prefer using Rufus on Windows. There are dedicated sites for it and for Ubuntu. Rufus allows you to load an OS.iso file onto a USB drive and run it. You can boot from the BIOS and then select "Try Ubuntu" to get a temporary setup where you can test audio and perform a quick speed test in Firefox.
It's odd, but sometimes a cable might not meet the required specs and won't support Gigabit on one NIC while working fine on another. People seem to run into this issue regularly on the forum. It appears more frequent now with the introduction of 2.5Gbit adapters in motherboards. Is it Realtek or Intel? If it's Intel, what revision is it? Early versions had hardware issues that were resolved in REV3 (B3), and one common symptom was dropping to 100Mbit.
I think it's an Intel NIC. The issue isn't reaching 100Mbps—it started at 8Mbps after adjusting speeds in "Speed and Duplex" (which I later changed back). Also, the motherboard audio ports aren't functioning. My best choice seems to be a clean restart and replacing the motherboard from Amazon.
