Cable overhead? Pulling the most out of a 1gig internet with 2.5gig ports? (alien.top)

This may sound obvious but as I just had to run some cat7 to get my full 10gig to my nas I thought I would ask.

So I have a 1gig internet connection though spectrum, the cable modem notes that the port is a 2.5 gig port. Would I have any better connection if I connected it to a 2.5 port on my Ubiquity, and used higher cat cables?

Normally you never get your 1gig you pay for, but do you think I might get any more by having the cabling out of it be at 2.5? I normally get 912 Mbps on my speed test, so I know i'm scraping the barrel of what I can improve.

i did find that i got a more reliable/stable connection plugging my fiber media converter into a 10g port rather than a 1gb port on one of my switches. your mileage may vary but it’s worth a try

You’ll always hit slowdowns once you get to the big bad web. Your LAN can be supersonic, but the internet isn’t. I have fttp 1Gig synchronous. It was close to that at install but not anymore. Average 350 with bursts up to 800+.

cat5e can handle 1gbe, 2.5gbe, 5gb and 10gbe over short distances...

“Cat 7” is not a real thing. It’s just high-spec 6A, and the higher spec doesn’t do anything for Ethernet speeds because 10GBaseT is already supported with plain old Cat6A or even Cat6 at shorter distances.
