Any help would be greatly appreciated. Hi, I try to give some initial help. The linux-wireless driver is supported by ath9k driver see [1] and [2]. Unfortunately, you have not sent any log-files at least your dmesg-log. No output of the above userspace commands or userspace-tools versions. No information to VendorID/ProductID (PCI, USB, whatever). It's not clear to me if this is a kernelspace (ath9k-driver) or userspace (CRDA/regulatory) problem. How should someone help you effectively? The linux-wireless wiki has somne informations on how to debug Atheros/Qualcomm ath9k-driver, see [3]. As a debianist I say try Linux v4.16 Debian packages from stretch-backports (and maybe a higher version of wireless-regdb). Try to ask questions the smart way [4] :-). Hope this helps.
