charlemagnelasse:

  • Device problem occurs on: PC-Engines APU3
  • Software versions of OpenWrt/LEDE release: LEDE 17.01.4

Just created a monitor interface with an WLE200NX:

config wifi-device 'radio0'
option type 'mac80211'
option channel '5'
option hwmode '11g'
option path 'pci0000:00/0000:00:02.5/0000:04:00.0'
option htmode 'HT40'
option disabled '0'

config wifi-iface
option mode 'monitor'
option device 'radio0'
option ifname 'mon0'

And restarted the device. It was expected that the monitor interface is now in HT40 mode (able to receive on HT40) and on channel 5. But in reality, the device was now on channel 1 and used a 20MHz (non-HT) channel setting:

root@LEDE:/# iw dev
phy#0
Interface mon0
ifindex 7
wdev 0x2
addr 00:11:22:33:44:55
type monitor
channel 1 (2412 MHz), width: 20 MHz (no HT), center1: 2412 MHz
txpower 20.00 dBm
