Did you tried to use latest > firmware? > https://github.com/qca/open-ath9k-htc-firmware Yes, it is. I have just tried latest firmware from git, it is still not working as expected. Ubuntu 13.04 comes by default with FW v1.3, I can confirm that I really used the new one, as now the kernel tells me it is FW v1.4 (before it was 1.3). Should I open an issue ticket on open-ath9k-htc-firmware? How can I make sure where the problem comes from?
