I came to the conclusion that this issue is related to ath5k driver with AR2413 wireless chip communicating with the Netgear WGR614 router via WPA2 protocol. The wireless chip here does matter, since I have another notebook (ubuntu 10.10, on 2.6.35* kernel, ath5k with a different chip though) that does not have the said problems.
Discovered that ssh and rsync also suffer from the throttled traffic when run wirelessly. In fact, rsyncing both from and to the affected machine stalls, as well as sshing to it. That only happens while on the wireless connection. We are talking about the aforementioned Netgear's LAN in all the cases. I downloaded a 1 year old 2.6.35 kernel. It seemed to be better, however, sshing to the machine would also freeze in the middle of the session. This is very weird taking good numbers from the connection speed test ( testmy.net ) into account makes it more weird. Not sure what to do next. My nest suspicion would the combination the wireless card, router and the WAP2 authentication protocol. I will try turning the latter off and or trying other ones. -- Sent with mutt, composed in gnu emacs Please do not send me Microsoft Office/Apple iWork documents.

In all of these firefox 7, chromium, epiphany and konqueror are pretty fast, except on Narwhal when visiting some websites I noticed that on 11.04: 0) never happened on the affected laptop before 11.04 1) pages without js are rendered alright 2) when js is disabled on firefox4 it seems to speed up some not all, though, e.g. it does for cnews.ru, but not for launchpad.net (which never loads) 3) w3m-img,elinks,lynx are fast and load those pages in questions alright 4)none of these problems exist on 10.04 or 10.10 with web browsers of the same versions 5) it is an Ubuntu 11.04 only issue, does not happen on older version of Ubuntu 6) does not seem to be an ipv4/ipv6 issue, since on firefox I set ipv6.disable to true On the affected machine (as well as on the others) I got a custom kernel installed. uname -a: Linux 2.6.38.5-mine #1 SMP Wed May 4 12:28:50 CDT 2011 i686 i686 i386 GNU/Linux --- Architecture: i386 DistroRelease: Ubuntu 11.04 Package: linux (not installed) ProcEnviron: LANGUAGE=en_US:en LANG=en_US.UTF-8 SHELL=/bin/bash Tags: natty Uname: Linux 3.1.0-rc6-mine+ i686 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: Upgraded to natty on 2011-05-06 (160 days ago) UserGroups: adm admin audio cdrom dialout dip floppy fuse lpadmin netdev plugdev powerdev scanner video voice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/788274/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
