   They can make an adapter for $10 retail, with an actual   
   RealTek chip inside it (not even an RF metal cover over   
   the active circuits). Why would you need to make a fake ?   
      
   Any Wifi without a Bipolar PA after the MAC chip,   
   we don't really know how long those will last. The companies   
   that make the unreliable ones, certainly don't worry their   
   pretty heads about failures. There is an issue with CMOS PAs   
   losing the will to live after three months of operation,   
   which could be an electromigration failure (high current,   
   high temperature, high frequency). I would expect an Intel AX,   
   the people making that should have some electromigration   
   data to make a judgement on the wisdom of their design.   
   Companies which are "fabless", less so.   
      
   It has also been noticed, that the output power level of   
   cheap Wifi adapters, seems to vary a bit when they are   
   brand new. If you bought two, one would reach the basement   
   router, and the other would not. Then, after three months,   
   there would be more separation in performance, between   
   winners and losers.   
      
   We don't have a lot of sites now, to review these things for us.   
   Some useful sites shut down. In one case, the guy doing the   
   work, was getting sick of doing it :-) which is the best reason   
   to quit, if you need to quit.
