Got a Mac Mini (mid 2010) and noticed that during file transfer my speeds were just around 11MB/s. All the other computers in the network are 1000, so I changed the cables a few times, changed ports on the Netgear switch (connected to a Tomato router), but no dice. Network utility reports 100Mbit, and changing/forcing it to manually connect at 1000Mbit/s (full-duplex, full-duplex w/traffic, etc., std. frames, jumbo frames, all combinations thereof) cause it to not connect. It'll only connect at 100Mbit speeds. Cable is 6-7ft long, one cat5, other cat5e, tips good, all looks fine from what I can see. Any thoughts?
