Sorry for offtop.
Maybe somebody knows, is it possible to extend channel width to 160MHz
on this chip?

=E2=9D=AF sudo iw wlp5s0 info
Interface wlp5s0
ifindex 3
wdev 0x1
addr 48:e7:da:57:9a:33
type managed
wiphy 0
channel 44 (5220 MHz), width: 80 MHz, center1: 5210 MHz
txpower 3.00 dBm
multicast TXQ:
qsz-byt qsz-pkt flows drops marks overlmt hashcol tx-bytes tx-packets
0 0 0 0 0 0 0 0 0

=E2=9D=AF sudo iw wlp5s0 set channel 36 160MHz
Usage: iw [options] dev <devname> set channel <channel>
[NOHT|HT20|HT40+|HT40-|5MHz|10MHz|80MHz]
Options:
--debug enable netlink debugging

--=20
