Comment 16 for bug 201225

I've was having the same problem on my dell 2650 laptop, but after running iwconfig <ifname> rate 54m and turning off cts protection on my AP, i was able to get download speeds of over 6MB/s using the speedtest at http://www.speakeasy.net/speedtest/. when looking at dmesg | grep <ifname> i noticed the interface is flapping between long and short preamble, but it doesn't seem to have an affect on the connection speed or reliability.
