After upgrading my home router from an old device with 802.11g(?) to a model supporting 802.11n, I could not connect to wireless anymore, could not even ping the router itself.
Noticing the line in /var/log/syslog and googling for ... iwlwifi ... Tx aggregation enabled on ra = ... tid = 0 I noticed this bug report. As suggested here, creating a file with one line so: $ cat /etc/modprobe.d/iwlwifi.conf options iwlwifi 11n_disable=1 allowed things to work just fine. My kernel version: $ uname -a Linux psz-laptop 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:32:50 UTC 2012 i686 i686 i386 GNU/Linux --- I tried to use "apport-collect 974838" but it told me this bug was not mine. Instead I attach extracts from /var/log/syslog: syslog.old-without-802.11N Logs with the old 802.11g(?) router syslog-bad Logs with new 802.11n router, cannot connect syslog-good Logs with new 802.11n router and with 11n_disable=1 workaround --- Cheers, Paul Paul Szabo p...@maths.usyd.edu.au http://www.maths.usyd.edu.au/u/psz/ School of Mathematics and Statistics University of Sydney Australia ** Attachment added: "Logs with the old 802.11g(?) router" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974838/+attachment/3430322/+files/syslog.old-without-802.11N -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974838 Title: Wireless Dropout - Tx aggregation enabled on ra (workaround: iwlwifi requires 11n_disable=1) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
