After upgrading my Xfinity plan to 900 Mbps last week, I have been pulling my hair out trying to figure out why I'm not getting close to that speed on my Windows 10 machine.
Through process of elimination, I have ruled out the router and the cabling. I have tried multiple different modems, all capable of multi-gig speeds, and all with very similar results (about 600 Mbps on average). Xfinity has been out to my house twice and verified all the signals. After the first visit, they recommended I get a different modem, but that didn't solve the problem. During the second visit, they tested the speeds at every point in the chain and were able to show me that the modem is sending a consistent 950 Mbps to the PC.
That got me thinking that maybe it is the ethernet port itself that isn't capable of handling the additional speed. I don't have any other computers in the house, but I realized I could run a speed test on my wired Xbox Series X, which returned 900 Mbps. Then I dug a cheap USB to Ethernet adapter out of my closet and connected that to my main computer again, and I got readings right around 900 Mbps again. So my onboard ethernet definitely seems to be the problem, but why?
I have an ASUS Maximus IX Hero Z270 motherboard, which has an Intel I219-V ethernet connection. I checked that the drivers are updated and also updated my BIOS and confirmed the settings there. I have ordered a cheap PCIE NIC that I'm hoping I can squeeze into my one available PCIE slot (it's going to be a real tight fit next to my CPU cooler). Assuming I can fit it in the slot, I'm hopeful that will solve my problem. Other than installing a new card, is there anything else I could be doing with my onboard ethernet port to try to solve the problem? Or is it just showing its age at nearly 6 years old?
