Good evening the problem is this:

I bought two 60ft rj45 cat5e cables.

One worked the other one didn't work. it didn't work on different computers, and when I went to the store to have it checked it immediately worked for the guy who sold it to me. Why do you think it happened? I tested the cable on both my desktop and laptop. I tested it on different points of my arris router. It is an arris DG1670.

I'm using windows 10 on all computers. I want to use it on laptop or desktop. It goes between unplugged and identifying.

Frank.

sounds like a loose connection on the RJ-45 plug itself.
only 2 options I see, replace the entire cable or replace the ends.
first is self explanatory, second is problematic unless you have a crimp tool and ends compounded by the fact that many pre-made cables are stranded copper not solid copper and the crimping then becomes a problematic at best

I have had those too, are you sure it was working? did he actually transfer any data over the cable and verify it was received? did he make the cable?
IDK why his tester worked, but I do know it does not work for you. does the other cable work on all your equipment?

A loose connection is just that loose and sometime it will work and sometime it will not, replacing the ends and testing again will verify if the cable itself has a short.
check the wires in the plug and make sure they are in the right order

You have few options as home user. You buy a premade cable or you reterminate the ends. To really test a cable you need a tool that costs many hundreds if not thousands of dollars. That tool you posted is extremely basic. A home user little way to find a cable problem where it partially connected.

Even buying premade cable you must be very careful, there is a lot of trash on the market. I used to tell people to look for EIA/TIA markings but there is now fraudulent cable being sold with even those. You need to be sure you buy pure copper cable not CCA (copper clad aluminum) and the wire must be 22-24 gauge wire that really thin flat stuff also does not meet the standards.
