Comment 11 for bug 183796

I have been testing Intrepid for quite some time now. I have recently switched to 2.6.27-1-generic to test this particular issue, but the slow network performances are still there. However, as mentioned in the upstream bug report, using the module option qos_enable=0 solves the problem without seemingly affecting network performances in other configurations. Of cours this would have to be tested more thoroughly but I think it would be sound to add
options iwlagn qos_enable=0
to /etc/modprobe.d/options with a comment in this file as a workaround.

Please note that the orignial bug (ping issue) has been closed but that another one monitoring the data transfer rate issue
was opened some times ago
(http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1669)

There hasn't been many activity for this bug report recently however, besides the last comments on qos_enable=0.
