After seeing that my wireless speeds were much faster than the speeds I was getting over Ethernet, I decided to invest in some new cables. I didn’t know it before, but I saw while I was changing them out that my current cables were Cat 5e. While putting my network together, I had just been grabbing whatever cables I could find in my scrap drawers. Now I have Cat 8 cables and my speeds jumped from 7MB/s to an average of over 40MB/s. It’s a much bigger improvement than I expected, especially for such a small investment.
Also learned this the hard way, when i was starting my “homelab” , I bought a box of (not knowingly that its bad) cheap CCA(copper clad alum) cat6 cables and im wondering why are my access points not negotiating to gigabit, turns out cca are trash and shouldn’t be used on POE or even on high speed trunks, learned my lesson now and swapped my cables to pure copper, they are more expensive like 100$ more expensive but at least they do the job.
CCA shouldn’t be used anywhere ever. It’s garbage cable for garbage people who will pinch a penny and end up spending ten times that in dealing with the issues and the eventual replacement.
