Question download speed won't go over 100Mbps on new build

[redcat123]

Downloaded every driver I could think of on new build and updated windows, my Ethernet Status shows speed at 100.0 Mbps.


Using the exact same cable and location as my old build that got over 800Mbps


Windows 10

Asus TUF Gaming B650-PLUS

The 2.5Gb port may be more sensitive to a marginal cable.
Is this with in-wall cable or a cable direct to your router?

I actually just fixed it, had to hard code it at 1.0 Gbps in my realtek driver settings in device manager under Speed & Duplex in case anyone else gets this issue.

That is not a fix. At some point the other end may still drop to 100Mbit and then you have ZERO connectivity.
You need to fix the cable and leave the adapter on auto.

You didn't answer the question about what your physical connectivity is...
You should start by temporarily running a new (even if long) factory made cable direct from your router. That should be a Cat5e or Cat6a cable, 100% copper with 22-24GA wire. I like the monoprice cables -- https://www.amazon.com/Monoprice-Flexboot-Cat5e-Ethernet-Patch/dp/B00KWS7GAC

Cable runs directly into router and is cat 5e, will order a cat 6 monoprice cable
