When I installed Ubuntu on a laptop at home, my Internet performance was
horrible. I had installed Ubuntu before, but never had any issues. I
then installed Etch, same issue, same laptop. I tried other OS's
without any success. I then tried an older version of Debian and it
worked fine. I searched Google and found a little blurp about window
size and routers and the newer kernels.
I don't know if this will help you, but with the machine running, open a
terminal window, go to root mode and cat
/proc/sys/net/ipv4/tcp_window_scaling. If it is set to 1, change it to
0 with echo "0" > /proc/sys/net/ipv4/tcp_window_scaling. Close FF and
try again.
The difference was night and day for me.
There are a few work arounds, but if this works and you want a permanent
solution, add "net.ipv4.tcp_window_scaling=0" to /etc/sysctl.conf.
I know there are other settings, but this worked well for me.
