I spent ~$35 on new cables and my LAN speed increased 6x (sh.itjust.works)

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.

Cat 5e

The fact that your old cable was cat5e has no bearing whatsoever on you getting shit speeds before changing cables. The gigabit spec was codified and products were on the market before the cat5e spec was ratified. Gigabit ethernet was literally made for standard cat5. I bet your previous cable was terminated incorrectly, and was only using two of the four pairs, limiting you to 100mbit.

Bingo!

Proper termination can be a bitch.

You pass! I’ve done several thousands of these over the past decade.

[–] [email protected] 5 points 3 months ago

yeah I did this almost 30 years ago and could recite it from scratch, haven’t made a cable since hs

Now do the A spec.

[–] [email protected] 10 points 3 months ago

I have not cared about or terminated A-spec after network cards gained auto MDI/MDIX about 20 years ago.

I forget the order 5 times in the middle of crimping each side, so you're doing better than me.

Ewwww orange first? Why are you making a crossover cable backwards for?

I thought T568B at each end was standard practice these days

[–] [email protected] 5 points 3 months ago

Depends where in the world you are.

We use A in Australia and from what I have seen in western Europe A is also used more.
