well what you should be doing is mentioning your effort's to solve it and adding information !!!!! damn that's just lazy you fail at failing for not even trying or specifying that you have tried !!!!Whats more to say. No functionality at all, not even visible
did you try asking the magical wifi fairy's to solve it ????
1 ) did you check is the firmware loading ,DRIVERS etc etc
2 ) what computer you have ? desktop, laptop or Peewee PC ....
3 ) did you try blacklisting dependent on your machine it maybe be a module conflict problem
4 ) spend some time problem solving and exhaust all options and efforts before moaning
5 ) Did you try unblocking your wifi using rfkill [ is your computer wifi switched on by a switch or by key press [ these are things you need to check ] simple stuff but people over look it sounds stupid but it happens when it comes to linux they are to use to windows spoon-feeding them and expecting windows to sort everything out for them !!! This is linux WELCOME TO THE REAL WORLD !!!!!
6 ) POST INFO ON YOUR efforts using grep,modprobe etc etc and so on and so fourth to discover what is loading and what is not * when posting info only post valid info regarding your wifi not the compete kernel log *
"Try and fail, but don't fail to try."
responses will always be a lot different i.e pleasant, when you actually show you are trying and the help will me made a lot easier
for the community as information is key to solving any problem in linux. the community can not READ MINDS !!!!!!
