With an old laptop that I always use, now I realize that the internet is slow downloading single-connection, and I have changed the MTU to 1400 and it is perfect, why is this happening? I already had that feeling for a long time that in M$ the internet went faster
With M$ a MTU 1500 goes perfect
MTU 1500 vs 1400, my connection is 100/100 Mb/s (This happens with any download)
