I don't see any of the above issues  w/ the 4965 card I have but I don't 
use it often.  Given how little information you've provided it's 
unlikely anyone can help you diagnose your problems and even less likely 
changing the fw would matter.  If you want to pursue these problems I 
suggest you file a PR with details but to be honest I'm not aware of 
anyone actively working on the driver.
