Note: DO NOT(!!!) use the "irqpoll"  boot parameter. This causes the network card to lose it's irq, and makes any stability of the network connection impossible.

Note: There is a [[Problem with e1000: Open issue with latency|known issue]] with the e1000, t60/t60p and the 2.6.17 kernel. It is unconfirmed if this issue effects other configurations.<br>

Note: Another possibility is to use "RxIntDelay=5".

For Gentoo users - compile e1000 as a kernel module and add 'options e1000 InterruptThrottleRate=0,0' to /etc/modules.d/e1000

I had serious performance problems on Ubuntu Edgy (ca. 400 kb/s File transfer rate).
+
I compiled version e1000-7.3.20 from http://sourceforge.net/projects/e1000/ and this solved my problem.
+
All other hints above did not improve the file transfer performance (they did improve the ping latency) for me.

+
Note: There are some problems with the driver since kernel 2.6.17 (at least on a Z61p, Z61m). After an ifdown && ifup it doesn't work anymore. A possible workaround is to build the tg3-driver as a module and reload it when this problem occours. (Adding ''pre-up modprobe tg3'' and ''post-down rmmod tg3'' to the corresponding section in /etc/network/interfaces works fine.) Rebooting the machine would also be possible.
+
This is fixed in kernel 2.6.19-rc5.
+
 
+
The T43 with a stock Linux 2.6.18.1 kernel does not have any problems.

Internal Ethernet controller

A variety of Ethernet controllers is integrated into almost all models starting with the introduction of the A, T and X series.

The Ethernet controller is located on either a MiniPCI card, Communications Daughter Card (CDC), or integrated on the systemboard.

3Com

Intel

Broadcom

Realtek
