RE: [PLUG] How do you set a NIC to only be 10mbs in Linux?
|
mii-tool is a for 100Mb/s cards only.
you have gigabit NICs.
ethtool is probably the command you want to use.
mii == media independent interface
i think it refers to a layer within the NIC that's just above the
transceiver. 802.3u (i think) supports transceivers for media other
than dual twisted pair.

Also make sure you don't have any other media connected to your hub, switch, etc that is 100 mbps full duplex, otherwise you will see a lot of collisions. If this doesn't work, describe your problem in a little more detail.
