Comment 11 for bug 420678

I have the same "ERROR: No TX rate available." issue on my Intel 5300 on Ubuntu Karmic.
I am using a NETGEAR AP.

I'd like to add that I also have serious speed problems:
In 802.11g the speed is sometimes limited to ~100kb/s even when I am right next to the AP.
ifup and ifdown on the interface helps.
In 802.11n mode the speed is also sometimes limited to absurdly low throughput of ~750kb/s, again down/up-ing helps.

cat wpa_supplicant.conf
ap_scan=1
network={
        ssid="private"
        scan_ssid=1
        proto=RSN
 pairwise=CCMP
        group=TKIP
        psk="removed"
}
