Well, as I had said in previous posts in my house AirDrop never worked between my MacBook and my iPhone 5s/ iPad mini no matter what I have tried. Between iPhone and iPad it always works.
When I go to a friend's house Airdrop always works without changing any settings. Just turn on the AirDrop and it works. During Christmas my friend had left and disconnected the router. I went over the house to check it and test a couple of things with AirDrop. Turned on the router but no AirDrop!
I dropped by my friend after he got back and Airdrop was working again. The only difference was the router was on for about 24 hours.
What I did, Ι left Airdrop on so I could see my iPhone on the Mac, prevented MacBook and iPhone going to sleep and returned home.
Airdrop was working at my house.
AirDrop was not working though between my iPad mini and my MacBook + iPhone!
I was not expecting this to last and it didn't. It lasted 1-2 days. I checked AirDrop and iPhone and MacBook don't see each other anymore, but Airdrop between iPad and iPhone started working again.
What I intend to do is use a router I have which is the same with my friend's. Model, firmware, settings - everything and let it run.
I had done this test again but I never let it run for more than a couple of hours as Airdrop was not working.
If I get lucky I will post back.
Another strange thing I want to report is that my Macbook could see the iPhone on the AirDrop page even it the Airdrop on the Mac was set not to be found by anyone which up to now I was translating it to Airdrop off!
P.S. I noticed that my Macbook has the mura issue. Depending how apple responds to that as it is under warranty until 26/1 I will decide if I continue purchasing apple products. We pay a lot for not having things work as the meant to be.
