Wired LAN Internet access very slow on ArchLinux

This only happens when I access the Internet via wired LAN, which I only do at my dormitory (there I also have to use a proxy). Speed is 40 - 60 KiB/s.

The Windows 7 installation does not show this problem; there speeds can reach a constant 1 MiB/s.

Other than that access is fine. The chip used is (iirc) an Atheros AR8121.

(I also use WLAN at home, there no such issue occurs.)

ifconfig -a:

Help, please?

Re: Wired LAN Internet access very slow on ArchLinux

I do not know if this will help, but could it be related to IPv6?  I have noticed some people getting slow connections when it is enabled.  I can't even get to any websites at my Dad's house if it is enabled.

Try adding     alias net-pf-10 off
to /etc/modprobe.d/modprobe.conf

Re: Wired LAN Internet access very slow on ArchLinux

Thanks for the reply, but I've already disabled IPv6 upon installation.

Hmm. I wish I knew more about networking so I could really help you. If I come across anything, I will be sure to let you know.  If you figure it out, be sure to post back!

Also, check that your hostname is set correctly in /etc/hosts. It should look like:

127.0.0.1 localhost.localdomain localhost <yourhostname>

Re: Wired LAN Internet access very slow on ArchLinux

That was set on installation as well. It appears to me as if nothing was not configured the way the ArchWiki tells to - weird, in a word.
