Are you saying that your solution will take care of every connection problem that occurs with a laptop that has a crappy internal wirless problem? I wouldn't think so. Besides, how many laptops have been produced that have an intenal wireless card? If all were that bad, the manufactuers would probably not include them with the unit and suggest that one would go with the 'ball and chain' adatpter you have suggested. Also, I have a wireless N router. Can you tell me how I can achieve 300mbs on my laptop with the alfa?
I appreciate your experience with laptops and respect you for that. I, also, am an electronics technician with 23+ years in board level repair, test engineering experience and IT experience. I am sure you are more experienced with laptops than I am. But, when it comes to troubleshooting, I will put my foot down to say that there is not one solution to any problem. All my years of experience has taught me that. Too many variables, too many solutions! Peace!
