sudden slow internet speed on windows 11

I just upgraded to 1Gbps fiber from Starlink, and after doing speed tests on my main computer, I wasn't getting the speeds my router and laptop (Win 11) were getting. I even went as far as finally setting up the 2.5G network card and switch on my network. Turns out both of the Intel network cards, 1G and 2.5G, had bad Windows-supplied drivers. 

The Intel Driver & Support Assistant did not see that the network drivers were outdated, but searching the Network Chip, Intel does have an Ethernet Adapter Complete Driver package at https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html After unzipping the file run Autorun.exe and Click Install Drivers, Yes to UAC, and Ok to the update. This took me from version 1.1.3.28 to 2.1.1.7. Now my speed tests are as expected with ethernet overhead.
