How to tell if my card is gigabit or not

I decided to undertake, slowly, a project to upgrade my home network
to gigabit speed. Starting with the main switch, I want to buy a 16
port gigabit speed switch.

I have a basement server computer with nVidia's CK804 chipset and
network built into the mobo.

My question is how to tell if this thing supports gigabit ethernet, or
not? At the moment I have no other gigabit speed devices. thanks

"lspci" will tell you what sort of Network Controller is on your board.

That's exactly what it said:

root:~ ###lspci|grep Ethernet
00:0a.0 Bridge: nVidia Corporation CK804 Ethernet Controller (rev a3)

Perhaps, one of these will give the details.
# ethtool eth0
# mii-tool eth0

The network card in my system gives the details you are looking for using
ethtool.

It should do; use "ethtool -i eth0" (as root, and assuming that the device is
indeed present as eth0) to check.

Thank you!!!!!!!! This is beautiful!!!

This ethtool is great. I used to use mii-tool for my laptop, which
stopped working in FC7. So I stopped using it, which was bad. Now I
know to use ethtool instead. For my basement server, it says:

root:~ ###ethtool eth0
Settings for eth0:
Supported ports: [ MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
1000baseT/Full
Advertised auto-negotiation: Yes
Speed: 1000Mb/s
Duplex: Full
Port: MII
PHYAD: 9
Transceiver: external
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Link detected: yes

So I think that I am all set for gigabit speed.

Yes. It supports gigabit. My house is wired with Cat5e wiring, a
little haphazard, though. What speed do you think I could attain?

You're likely to be throttled by other factors-- hard drives & OS.
Just because you can send a packet at 1000 MB/sec doesn't mean you can
generate them or process them at 1000 MB/sec.

Why? Is this a hobby? since I find it extremely unlikely that you are
transfering gigabytes of information between your home computers regularly.
It will help not at all with your surfing or getting stuff from outside
your home.

So the network will be totally useless. networks are for transfering
information between computers. gigabit will not speed up transfers between
one computer with a gigabit card and another with a 100Mb card.

No you are not. as I mentioned you need two computers, and all links
between to be gigabit to get any speed improvement.
