I am HAVING A BIG ISSUE WITH WIFI CONNECTION, after clicking under internet interface, I always have the Thunderbolt of interface box always ticketed. however I have the conclusion of not using Thunderbolt on my MACBOOK PRO, at all. also checking on proxies config I notice that the setting for bypass proxy settings and hosts & domains box Alway ave had a command (*.local,169.254/16) However I never contract a private domain non either

had a FTP MODE on my (PASV).
