I checked all the wireless channels which my adapter supports.
#ifconfig -v ath0_wlan0 list channelChannel 1 : 2412 MHz 11b

I changed my settings to channel 13 since that is using only ht/20. Is that ok
for further testing?

no, you'll have to ask the pfsense people if they provided a UI to set
the channel to HT/20 only.
