The brother's computer has recently begun experiencing problems while playing online games.
I have a switch near the attic that connects one cable to my PC and another 50 or 100 feet to my brother's computer. Everything worked well before, with no lag, but lately he's reported slower speeds—about 150mb down and 50 up, while his is around 45 down and 25 up. Appreciate the advice!
Assuming they're reversed, it might be due to an unusual cause. Checking packet loss with iperf3 on each machine could help identify the problem.
