Start on 2.4 GHz AP with HT Only (not just HT40) set. That is, AP that doesn't allow 1 Mbps packets to be sent. Scan, make sure 1 mbps packets are sent.
I configured my AP with the conf file below. Radio is configured for HT20. Is that what you mean?? On channel 3 (off-channel), probe request is sent at 1Mbps On channel 8 (on-channel), probe request (and deauth) is sent at 1Mbps.

Start on 5 GHZ AP with HT Only set. Scan. What rate are probes sent at for 2.4 GHz?
(Using slightly different hostapd.conf config file, of course) On 5Ghz channels, they are sent at 6Mbps On channel 3 (2.4Ghz), they are sent at 1Mbps That seem right?
