I already know that it will not be achieved, but I am most puzzled by the fact (apart from the quality of the contacts) that the speed is the same at 20 m and 1.5 m. In a week I will order a cable and replace the sublime crimper. I also think that the contacts have a big impact, but today I was earning a few and I am not able to jump over the speed of 85 Mbps.

Hello again
I bought a UTP cat 6a - 30m cable, for a test, I put the plugs on, so far with this faulty crimping tool, but it did not work out too bad. almost 520 Mbps - that is, as I suspected the cable's fault. For now, I do not have time to put it in the slats, but if I do it, I will let you know if there is any interference - I hope it won't.

Best regards.

Topic summary

The discussion revolves around troubleshooting low internet speeds experienced on computers connected via UTP Cat 5e RJ45 network cables. The user upgraded their internet speed from 100 Mbps to 500 Mbps but observed speeds only reaching a maximum of 85 Mbps on 20 m cables, while a 1.5 m cable achieved over 520 Mbps. Various responses suggested that the issue likely stemmed from poor cable quality, particularly since the longer cables were found to be copper-clad aluminum and not true twisted pairs. Recommendations included replacing the cables with higher quality options, such as UTP Cat 6a, and ensuring proper crimping of connectors. After testing with a new Cat 6a cable, the user confirmed improved speeds of 520 Mbps, indicating that the original cables were indeed the source of the problem.
