Yeah, your driver (ti wl18xx) is simply not returning an BSSes for any of the scans. That's a driver problem, unless it really can't see any BSSes. Try rmmod-ing the driver module, then modprobing it again, and if that fixes things (because it re-inits the hardware) then the problem is likely in the kernel driver.
