In moving my computer I have mixed up the phone cord that went to my router/modem
I have tried all three, of which one did work before. In cable testing the 3 phone cords I got
the following results
1st Cord
Left Side of Tester 2,3,4,5 Right Side of Tester 5,4,3,2
2nd Cord
Left Side of Tester 1,2,3,4,5 Right Side of Tester 1,2,3,4,5
3rd Cord
Left Side of Tester 3,4 Right Side of Testor 3,4
Don't know which one to use, could you please help me with this?

Thank you for your time and knowledge with this problem.

Thanks to you both.
The problem has been solved by my daughter (non techie but has messed with the internet connection more than I so she can watch her TV)
The cord she used was the first one with the opposite run
I.E. 2-5, 3-4, 4-3, 5-2
Most phone connection use the center pair. Not sure what is wrong with the cable with only 5 wires. My guess is the last cord with only 1 pair is best. The second cable likely would work also since the center pair is corrent. The first one may also work since phone lines are fairly tolerant of the leads being swapped.
