Question

I was running Ubuntu 8.x on my desktop and everything worked fine. Im using wired internet and it worked perfectly, pages loaded pretty fast.

However, when I decided to upgrade to 9.10 the upgrade failed at some point, however I was left with what appeared to be Ubuntu 9.10. Since then the internet has been weird. When I go to a website it takes at least 10 seconds for the page to display, however if Im on a site and navigate to other pages on the website it loads quickly. This never happened prior to the upgrade.

I thought this may be due to the upgrade not installing correctly so I did a fresh install of Xubuntu 9.10 but the problems are still the same.

Im writing this on a Vista machine over the wireless network and internet is fine. Does anyone have any ideas of the issue?

Thanks.

This WLAN bug seems to be a common and not yet solved bug that comes with the upgrade on Ubuntu 9.10. So it seems you'll have to either try to downgrade to 9.04 or 8.x again or wait for a patch/bugfix. Some users also said they could workaround the problem using MadWifi drivers.

I heard that Ubuntu/Firefox has issues with IPv6, so disabling that might help. In Firefox you can do that by typing "about:config" into the URL field and then set "network.dns.disableIPv6" to false. To disable it system wide one would need to black list the IPv6 kernel module.

I haven't had the issue myself, so don't trust this answer to much.

Sorry for the cross-post, but I thought it might be helpful ...

Your problem does not seem to be a problem of (K)Ubuntu, but of your router or ISP (see Launchpad for a looong bug report). Therefore, I advise you to not disable IPv6. While this might help in short term, he problem will probably hunt you down again in one or two years when IPv6 takes over from IPv4.

The first thing you should try is updating your router's firmware. This completely solved the problem for me (and others). If this doesn't help, you should bug either your ISP or the router's manufacturer until they fix things.

That sounds like a DNS problem. As an experiment, find out the IP address of a site, then try navigating to it using that address instead of the domain name. If it's DNS, post a new question saying so.

*buntu 9.10 has problems with ipv6 on many installations. The only fix is to disable ipv6. To do this edit /boot/grub/menu.lst (assuming this is an upgrade. A clean install has grub 2 which is slightly different).

Find the line:

#defoptions=quiet splash

and change it to

defoptions=quiet splash ipv6.disable=1
