I checked all the wireless channels which my adapter supports.
#ifconfig -v ath0_wlan0 list channelChannel 1 : 2412 MHz 11b Channel 7 : 2442 MHz 11gChannel 1 : 2412 MHz 11g Channel 7 : 2442 MHz 11g ht/20Channel 1 : 2412 MHz 11g ht/20 Channel 7 : 2442 MHz 11g ht/40+Channel 1 : 2412 MHz 11g ht/40+ Channel 7 : 2442 MHz 11g ht/40-Channel 2 : 2417 MHz 11b Channel 8 : 2447 MHz 11bChannel 2 : 2417 MHz 11g Channel 8 : 2447 MHz 11gChannel 2 : 2417 MHz 11g ht/20 Channel 8 : 2447 MHz 11g ht/20Channel 2 : 2417 MHz 11g ht/40+ Channel 8 : 2447 MHz 11g ht/40-Channel 3 : 2422 MHz 11b Channel 9 : 2452 MHz 11bChannel 3 : 2422 MHz 11g Channel 9 : 2452 MHz 11gChannel 3 : 2422 MHz 11g ht/20 Channel 9 : 2452 MHz 11g ht/20Channel 3 : 2422 MHz 11g ht/40+ Channel 9 : 2452 MHz 11g ht/40-Channel 4 : 2427 MHz 11b Channel 10 : 2457 MHz 11bChannel 4 : 2427 MHz 11g Channel 10 : 2457 MHz 11gChannel 4 : 2427 MHz 11g ht/20 Channel 10 : 2457 MHz 11g ht/20Channel 4 : 2427 MHz 11g ht/40+ Channel 10 : 2457 MHz 11g ht/40-Channel 5 : 2432 MHz 11b Channel 11 : 2462 MHz 11bChannel 5 : 2432 MHz 11g Channel 11 : 2462 MHz 11gChannel 5 : 2432 MHz 11g ht/20 Channel 11 : 2462 MHz 11g ht/20Channel 5 : 2432 MHz 11g ht/40+ Channel 11 : 2462 MHz 11g ht/40-Channel 5 : 2432 MHz 11g ht/40- Channel 12 : 2467 MHz 11bChannel 6 : 2437 MHz 11b Channel 12 : 2467 MHz 11gChannel 6 : 2437 MHz 11g Channel 12 : 2467 MHz 11g ht/20Channel 6 : 2437 MHz 11g ht/20 Channel 13 : 2472 MHz 11bChannel 6 : 2437 MHz 11g ht/40+ Channel 13 : 2472 MHz 11gChannel 6 : 2437 MHz 11g ht/40- Channel 13 : 2472 MHz 11g ht/20Channel 7 : 2442 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.
