I assume this was -vht160 which if -vht is issued should be a NOP.

you could just try

create_args_wlan0="country PT regdomain ETSI mode 11na -vht160 -vht80"

which sould limit you to vht40 (double check ifconfig once assoc) and see
if that is as stable compared to the ht40 you are currently using.

Remind me, this is on amd64, right?
