Possibly the same issue on https://bugzilla.kernel.org/show_bug.cgi?id=42583
This bug still exists afaik and the link in Comment #8 verifies since the error message is so similar. I have had two of these Atheros USB wifi devices. The first I obtained was a refurb purchased thru ebay. It lasted about 90 days. the secod was a brand new one purchased at HHGreg locally. It has now died after lasting less than a year. If I could find my receipt I would try to get another. As is I do not have a working device anymore. Both were Netgear WNA 1100. Closing resolved needinfo since the device no longer is dead. Another user may wish to re-open and pursue if they have the inclination or hardware
