Very slow Internet issue in 10.10/11.04

[Patrick Quick]

A couple of weeks ago, the kernel of Ubuntu 10.10 AMD64 x.27 updated to x.28. Upon reboot, my Internet speed went to a crawl (Remote Desktop, newsgroups, and any browser were all unusable). I rebooted the machine into Ubuntu 10.10 AMD64 kernel x.27 from GRUB and my speed went back to normal (22MB Comcast). Earlier this week I updated the machine again to 11.04 AMD64 beta and the exact problem has returned. Everything else runs fine on all of the recent kernels and I have installed no new software or hardware since this has occurred outside of the obvious updates with 11.04. Short of rebooting the machine to a kernel prior to x.27 (which still solves the problem in 10.10 and 11.04), do you have any suggestions to fix this?

I have a gateway Model: LT3103u with the AMD64 chip. Ubuntu 10.10 Internet performance was terrible when on battery. Using apt-get was very painful timing out all time. Updated to 11.04 beta and same problem.

Actually, after looking at the distribution numbers, my errors started when I received a kernal update for 10.10 a couple of weeks ago and remain affected in 11.04 with all of the current updates instead of the numbers I listed above. Sorry. Posted from work and not from the affected computer where I could be more accurate. I have another machine that I left at 10.04, albeit the 32bit version, that works fine and is blazing fast while plugged in the same router port as the AMD64 one or if just plugged into the modem.

This issue hit me about 4-5 days ago after a reboot. Both firefox and and chrome are affected. Websites that typically load in 1-2 seconds are taking 2-5 minutes to load fully. Some sites simply timeout and are thus unreachable. Disabling IP6 did not fix the problem.

It seemed like a DNS related problem so I took a wild gamble and used Google to provide DNS. Curiously my Internet browsing works at regular speeds again. I can now reach sites that i haven't been able to load for days and the Internet browsing in Firefox and Chrome is fast. Either of these links will guide you through it. No reboot required. It just works... Takes about 15-30 seconds to setup. It may be a temporary workaround as I haven't rebooted yet. I used the DNS servers address 8.8.8.8, 8.8.4.4

Have the same problem with a Dell Studio 1537. Slow name resolution in battery mode (connection, pings, etc, keep on). It fixs changing to Google DNS's (goes slow but better than before).

Greatings.

Same problem with 11.04, change DNS goes a little bit better but that's not really acceptable for my 10 mbit connexion, please ubuntu team correct this bug !!!

I have try the 2.6.39 kernel, that's the same,

I have try to disable IPv6 in ubuntu and firefox,

The problem is the same on my notebook with wireless, but with my notebook with win7 no problem at all.

Assigning to linux kernel.

This Report appears to detail the exact situation that I have been experiencing recently with a relatively new AMD64 clean installation of 11.04; but, for the sake of rigor, I have filed a (possibly duplicate) bug #824818 with complete Logs attached.

Patrick:
You submitted this Bug report back in April; have you had any luck finding a solution that actually WORKS? The suggestions noted above don't address the issue completely and I would prefer not to gum up the developers with unnecessary chatter if there's a workable solution out there for the current Kernel Builds.

Thank you!
