Ubuntu 22.04 - Network - Wired Connection says Cable Unplugged

I have a dual boot system running Windows 10 and Ubuntu 22.04 LTS and I cannot seem to get the wired connection to work correctly. I tried the following:

I installed ethtool

sudo apt-get install ethtool

and simply ran a command

sudo ethtool -s ens5f5 autoneg off speed 100 duplex full

where ens5f5 is my ehternet interface, obtained earlier with ifconfig.

I found that in Can't connect to my home ehternet network with 18.04 - Cable unplugged but when I implement that solution and run a speed test, it is much slower than using the wifi connection. I tried to substitute 1000 for the speed but it returns the error:netlink error: Invalid argument

I am content with the wifi speed but am curious as to why the ethernet connection does not seem to want to work at an acceptable speed.
