Wifi wont stay on geek squad stumped for last 4 months!
Been taking my macbook pro (bought Nov.26,2013) for 12 weeks and still cannot fix WiFi loss after being on for 40 seconds or less!
iMac, Mac OS X (10.5.8)
Maybe it is time to try something other than Geek Squad? Seriously, have you tried calling AppleCare? If you aren’t under warranty it will cost but if the problem gets resolved isn’t it worth the $$?
Of course with some extra information maybe we can help here. Where are you having WiFi problems. Do you have success with WiFi anywhere? Have you tried anywhere other than where you have trouble?
