The utility iwconfig is obsolete and not exactly up to date with the latest in 
wireless. I am not an expert on iw, but I think you want 'iw dev wlo1 link'.

I am wondering about the missing firmware stage. Had you not done the 'sudo make 
install' step, or did that step fail to install the firmware?
