Realtek 8139 ethernet very slow

[Eliot Stock]

I just bought a Hush PC with a Realtek RTL-8139 in it and put Fedora Core 2. The
driver is 8139too and works out of the box but is very slow. It's inconsistent
- some sites are faster than others, and DNS lookups seem slow. There are
postings from people with the same symptoms here:

1.
http://www.linuxquestions.org/questions/showthread.php?s=&postid=940951#...

and here:

2. http://seclists.org/lists/linux-kernel/2004/May/3109.html

1 Suggests this is power management-related, so I tried stopping the acpid
daemon - no joy. 2 suggests that upgrading to kernel 2.6.6 might fix it, so I
got that out of testing and upgraded, but still no joy.

Realtek's site has some drivers here:

http://www.realtek.com.tw/downloads/downloads1-3.aspx?series=16&Software...)

but they look old, and none explicitly say they're for 2.6 kernels.

lspci shows:

http://www.realtek.com.tw/downloads/downloads1-3.aspx?series=16&Software...)

/etc/modprobe.conf includes:

alias eth0 8139too

What to do?

Cheers,

Eliot Stock.

I suspect you are having ipv6 DNS-related problems.

Add the following to /etc/modprobe.conf

install ipv6 /bin/true

and reboot.   That'll kill ipv6 support.
