Could it be cause I ran a Bloatware remover /setting optimizer app cause my Ethernet net not to work right?

When I first got my new PC I ran one those apps that removes Bloatware, and auto optimize windows setting for performance,at time I didn't notice cause I only had T-Mobile home internet which never would reach 1gig ,now I have spectrum and my desktop only device that only gets to 250Mbps upload my phone gets, 1050upload on wifi, and my laptop with same ethernet cable as using in desktop gets 950D/1000u only my desktop doesn't hmm and it has a 10/100/1000 Ethernet port I tried one those 1gbps USA Ethernet adapters made it worse lol.im lost not sure if a clean windows install would help
