Dear all,
I have been trying to set up a wireless network (tested both managed
and ad-hoc mode) with HT40 enabled using Atheros chipsets and thus
the ath9k driver. In both cases, iw responded with:
Command failed: Invalid argument (-22)
when e.g. executing the command:
iw dev wlan0 ibss join network 5180 HT40+
Is this not implemented or is this a (known) bug?
System:
Linux OpenWrt 3.3.8
driver: ath9k
Best regards,
Erwin
