Problems with WLAN - iwm0

[Michael Neumann]

Hi,

I can't get my WLAN working here with iwm0 on DragonFly 5.8.0. It always shows
"status: no carrier". I double checked with a recent FreeBSD (12.1), and there,
the same commands on the command line work. This is an open WLAN, I haven't
tested it with wpa supplicant.  Note that on FreeBSD I have to explicitly
specify the channel, otherwise I can't get it to work either.

Any ideas?

# dmesg | grep iwm0
