So more then likely, you need to be looking else where. Next thing I would check is the link lights on the switch or NIC of the machines (switch is probably a better bet). See if it's indicating a 100mb/sec connection or 1000 mb/sec.

I would be surprised if you simply had 5 everywhere. It wasn't that long ago that you moved there. You are correct it is 5e, and I wired the house myself. I bought the cable. I just clump all cat 5 together and and all cat 6 together... >The other thing to check (assuming you did your own wiring) is that the connectors are on properly. I bought a wire checker which does this testing for me. Everything is truly switches. I stopped using hubs a decade ago. John W.
