Could you please answer the part of which channel(pri/sec) you are
trying to use? The screenshot of scan results showed APs on channel
1, 2, 3, 4, 6, 11, and 13+9, so I would assume you are looking at use of
40 MHz channel on 2.4 GHz band. I would also like to see debug log from
hostapd showing why it disables 40 MHz use.

If your configuration is trying to use some other primary channel than
13, I would suggest trying to use the same parameters as the other 40
MHz BSS was using (I would assume that 13+9 meant channel 13 with

In general, I would prefer to get hostapd closer to the 20/40 coex rules
described in IEEE 802.11 rather than providing mechanism for ignoring
these rules. They were added for a good reason and it would be better to
promote responsible use of the shared radio resource.
