Start on 5 GHZ AP with HT Only set. Scan. What rate are probes sent

No HT20 is not the same as HT-Only. I'm not sure how to set that. Jouni?
I found a post from a year or so ago that indicates hostapd doesn't
support this type of thing (that could have changed, of course).
Do you know of any commercial APs that support the HT-only feature?
(And/Or a general strategy for configuring it?)
On 5Ghz channels, they are sent at 6Mbps
On channel 3 (2.4Ghz), they are sent at 1Mbps
That seem right?
Yes, for a HT20 but not HT Only AP.
Seems to me that the probe-request is to any/all APs,
so how could we possibly know that we should send it
at 6Mbps v/s 1Mbps until we discovered and communicated
with it?
Just as there are G-only APs that don't advertise 1-11 Mbps in their
beacons, there are HT-only APs that don't advertise support for 1-11
or 6-54 Mbps in their beacons and *only* support MCS rates.
Well, I don't think my changes would have made this any worse,
so if it worked before, it probably still works.
If anyone knows how to configure such a beast, I'll run some
tests. Or, if someone else has an AP like this, please let
me know if you see any problems with these patches.
Thanks,
Ben
