2015 13" MBPr A1502 I am wondering if this is normal since I occasionally lose internet service even though showing full wifi bars— When I click on the wifi bars in the top menu bar the first line is always grayed out. It says "Wi-Fi:" and then continuously cycles between ": On" and "Looking for Networks...", each showing for about 3 seconds. Is this the way it is supposed to operate? I've had this and other issues before and after having this MBPr repaired by Apple a month ago, 3 hours online with Apple support, two visits to Genius bar including a 90 minute visit two days ago.... I was told yesterday that the above situation is normal, but I'm not quite buying it. Can anyone confirm that theirs is [not] doing the same. Thanks!
