All right, I installed Ubuntu 8.04, and unlike 7.04, I have a huge problem with slow internet...

I've disabled IPv6 in Ubuntu and Firefox, and it still goes really slow (5 minutes to load google..)

someone help?

You have to open your /etc/sysctl.conf file.

sudo gedit /etc/sysctl.conf

Scroll to the bottom and just add these lines to it.

net.core.rmem_default = 524288
net.core.rmem_max = 524288
net.core.wmem_default = 524288
net.core.wmem_max = 524288
net.ipv4.tcp_wmem = 4096 87380 524288
net.ipv4.tcp_rmem = 4096 87380 524288
net.ipv4.tcp_mem = 524288 524288 524288
net.ipv4.tcp_rfc1337 = 1
net.ipv4.ip_no_pmtu_disc = 0
net.ipv4.tcp_sack = 1
net.ipv4.tcp_fack = 1
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_ecn = 0
net.ipv4.route.flush = 1

run the sysctl to take effect.

sudo sysctl -p

That's it. It works with my adsl connection. For complete article about this, u can google 'speedup ubuntu'
There are numerous blogs explaining things like this

hope this helps
