The network was running on channel 14 which Madwifi limits to 802.11b for regulatory reasons (we have permission to use this channel). The strange part was ath9k: Using "iw dev wlan0 stations dump" I could see that the TX rate to the Madwifi node was stuck at 1 Mbit/s. An iperf run confirmed the miserable data rate. I could force the rate with "iwconfig wlan0 rate 11M" to something reasonable (once again measured with iperf). In the latter case, iw still claimed a TX rate of 1Mbit/s but iperf did show the expected data rate. The Madwifi node on the other end was happily selecting 11Mbit/s on its own. Any ideas? -- Regards Joerg __________________________________________________ Do You Yahoo!? Sie sind Spam leid? Yahoo!
