            Bug ID: 192950
           Summary: [iwn] Centrino Advanced-N 6205 slow on 11n, better on
                    11g
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: Needs Triage
          Severity: Affects Only Me
          Priority: ---
         Component: wireless
          Assignee: freebsd-wireless@FreeBSD.org
          Reporter: dieterich.joh@gmail.com

Above mentioned WLAN NIC only manages a maximum upload of 900 kB/s on an 11n
network on the 2.4 GHz band in my tests. By recommendation of adrian@, removing
ht and falling back to 11g mode improves the upload speed to 1.9 MB/s and
download to 2.9 MB/s.

Please see the thread on freebsd-wireless at
http://lists.freebsd.org/pipermail/freebsd-wireless/2014-August/004907.html for
a more detailed description of the problem.
