Hi Oleksij, Sure thing. I cloned your ath9k-htc-firmware-blob repository and copied the htc_9271.fw file to /usr/lib/firmware/. I then plugged in the TL-WN722N USB adapter, brought up the wireless device with `sudo ip link set dev wlp0s18f2u4 up; echo $?` (return code 0), and sat back and waited. I did not interact with the machine beyond keeping open an SSH session (via a wired interface) and watching the log file. About five minutes later, a similar error occurred as described in my previous email. I've collected some logging output with the command `journalctl -k --since=today`. You may find this log a bit more useful than the dmesg log linked to in my previous email. You can find the log here: http://www.ichimonji10.name/downloads/tl-wn722n-journalctl.txt -Jeremy "Ichimonji10" Audet -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
