<https://support.metageek.com/hc/en-us/articles/203532644-802-11ac-Channels>
for information
about how the channels line up. FreeBSD should be spitting out the primary
channel, not the "centre"
channel.
At home I use channel 36/vht/40+, and I've tested it with 80MHz too. Eg:
CACHEBOY_HOME 30:de:4b:db:46:0a 36 54M -72:-95
100 EP RSN HTCAP VHTCAP VHTOPMODE VHTPWRENV HECAP HEOPER
MU_EDCA_PARAM_SET RSNXE WME WPS
Can you use iw on your openwrt router to capture what its current config
is?
It's very possible there's some oddness around 80MHz and frame reliability.
I've seen some issues with
the initial association not completing - we don't currently retry the
initial frame exchange during association
(whereas Linux mac80211 does).
Can you try running your AP at 20MHz and 40MHz and see if it improves?
Weird thing... I set the AP to 20MHz:
# iw dev phy1-ap1 info
Interface phy1-ap1
ifindex 28
wdev 0x10000000b
addr 7a:d2:94:80:1f:ec
ssid HolyLan
type AP
wiphy 1
channel 149 (5745 MHz), width: 20 MHz, center1: 5745 MHz
txpower 20.00 dBm
multicast TXQ:
qsz-byt qsz-pkt flows drops marks overlmt hashcol
tx-bytes tx-packets
0 0 67 0 0 0 0 20434
67
Then I reset the client and tried again and it still wants to use channel
153:

What's your country set to on FreeBSD? I am asking as UA is set to
"none" in regdomain.xml which means at best it'll do HT most likely?
I haven't checked the freqbands supported there.
What does ifconfig -v wlan0 show chan and ifconfig -v wlan0 show regdomain
show?
Just a random guess.
