I need to find out how my network card is configured. I am not talking about using ifconfig to find the ipaddress etc but I need to know the low level configuration. For example how is my card configured as regards speed? Can I force it to a particular speed (10/100/1000)? Is this a standard and easy to do thing or is it driver dependent?

Thanks

What kind of card and module does it use?
There are some networking drivers and utilities at http://scyld.com/ and at least some of the modules have options to force full duplex etc.

I am not sure of the exact model number of the card without doing some digging but it is an Intel card. The driver is called e1000.

most new ethernet cards and switches are set up for 'auto-sensing'.... They will check the speed of the subnet and set their speed accordingly. A 10/100 card will not go 100mbs/sec if there is another machine on the LAN that has an old 10mbs card. The speed of a LAN is dictated by it's slowest device, including switches. Hubs are 'dumb terminals' which basically spew out everything as fast as they get it (out of all the other ports). This is why switches are so much more expensive, they are smart because they know which port has a particular MAC address and don't spew it out of all the other ports.
