ath9k driver question & hardware support(-1 channel)

[tasoss]

Hello and nice to meet you.I'm having problems using aircrack.
My laptop's wifi nic uses the mac80211 stack.The driver used is ath9k.
The problem that i face is that mon0 interface's channel is recognised as -1.
I'm using the latest version of kali.
Do i have to patch the drivers?
Is my hardware not supported?
Can you please point me to some documentation?
Thank you!

Make sure that no network software is running, use

Service network-manager stop

And

Airmon-ng check kill
