Those Atheros chips are nothing but trouble and have countless compatibility issues due to their age and lack of support, there is some unofficial drivers out there.
if yours is an Atheros adapter then try finding a better driver here https://www.ath-drivers.eu/
If that fails i suggest you disable the adapter and install a small USB one, or if your system contains an internal adapter thats easily accessible beneath the cover, you can probably find an Intel or other similar adapter.
