I have a very similar problem with a 64G stick and an iPhone 5s running iOS 10.3.2. Your solution of placing the phone into airplane mode, then turning on the wifi also works for me. However, this is not a very good solution SANDISK PEOPLE!
Are there any Sandisk engineers monitoring this forum that know how to fix this problem? And dont suggest changing the channel from default…wasted a bunch of time trying all channels, but nothing worked.
This product is pretty worthless in my opinion and I’ve wasted way too much time trying to get it to do the basic thing it is supposed to do!
