Oh, dear! Do you mean the software driver (which is from TI) or the 
actual hardware device (wl1251)?

If it is the software driver then I may have a very small ray of hope 
that if I could manage to replace TI-supplied wl1251 driver with the 
Linux wireless-made driver for TI-1251 then this might solve it, right?

This may have something to do with the wpa_supplicant version I am 
using, which is 5.11 and unfortunately, I don't see a way to 
replace/upgrade it unless I manage to switch to the Linux wireless stack 
(compat-wireless) and use the driver supplied there.

Is there a way to verify this 100%?

If it is the hardware then that is out of the question, at least for 
now. If it is the software driver, then I may have a chance as I pointed 
out above.
