Slow Internet on Ubuntu

Kevo

Hi
When using a browser in Ubuntu the pages load very slowly. Its strange because its only slow when switching to a different server. Links which lead to a page on the same site work as usual but anything which links to another server takes bout a minute to load. Anybody know why this is?
Thanks,
Kev

This is almost definitely a problem with ipv6.
It occurs often in recent linux distros.
What happens is ipv6 is enabled by default,
but your system has no ipv6 nameserver available,
so it times out before getting the ipv4 name resolved.

Try looking in /etc/modprobe.d/aliases for a line like
alias net-pf-10 ipv6

If you find it, change it to
alias net-pf-10 off and reboot.
This is one of the few configuration changes that requires a reboot under linux.

If it's not there, post back - there are a few other places it might be hiding,
notably /etc/modutils/aliases, or /etc/modules.conf

Hope that's the answer,
good luck.

I tried this too and it seemed to make some improvement when web browsing - thanks!

Ok, I found the file you mentioned but it won't let me edit it. When I open it in the text editor any keys I press do not show up on the screen.

Edit

The file permissions only allow the owner to write to the file. I thought this would mean that I can write to it but at the bottom of the page it says "you are not the owner".

That file is owned by root. Use "sudo" before the edit command - for example, if you're using nano to edit it, type "sudo nano /etc/modprobe.d/aliases", and give your password when prompted.
