[SOLVED] Gigabit connection won't go past 100mbps

[Jamie554]

Hey guys don't know where else to turn. I've seen this thread a few times but none of the fixes have worked. I just installed a new mother board today and I have a persistent issue of my pc only detecting 100 mbps this was on my previous mobo too (both support 1000mbps). I can plug the ethernet cable as is right now into my PlayStation 5 and it will get 600mpbs. This tells me it is likely a software issue in my windows 10 but I swear i've tried everything except a fresh install of Windows 10. Any ideas?

If it's related to the motherboard's IO, I doubt it would be related to Windows. Since the cable you're using can also give 600Mbps to a PS5, it means the cable is not the bottleneck either.

I'd say make sure your mobo supports gigabit internet, but you say it does. It might be useful to provide the motherboard model.

My guesses would be either an option in the BIOS or some motherboard drivers. Recent motherboards offer a way to download and install drivers usually provided on a disk through internet in the BIOS options, try doing that if your mobo supports it.

Hey I have a MSI Z390 Plus I had a look on their website and installed their most recent lan driver and chip set driver but does not seem to have made a difference. I had a little dive in my bios and there weren't really any setting for ethernet

There are no real settings related to the speed, other than you can force it to 100mbps. You want to leave this all on auto. The speed is not really negotiated by actual software it is more of a hardware function done by detecting voltage levels.

Testing a cable by plugging it into a different device is not really a valid way to test cable. Cables can be just slightly out of spec and work on some devices and not others. It is going to be the cheapest thing you can try, you have already tried a different motherboard.

Be sure to avoid fake cables. You want pure copper cable (no cca) with wiresize 22-24 (no flat or thin cable). You need nothing special beyond that cat5e will work fine to 1gbit.
