My laptop connects to my Wifi but my iPhone does not. I connect my macbook air from the basement to the wifi and i get all 3 bars, but then i connect my iPhone from same place in the basement, the iPhone keeps losing the wifi.i had an iphone 4 before so I thought it was just the Antennas of the iPhone 4 that was weak. Now I have the iPhone 6 plus and its the same issue. what do you think is the problem? is it my router? i have a nether WNR1000v2 and it is upstairs, about 50-60 ft away from my room in the basement.
