Sandisk Stick saying no Internet connection

I have the SanDisk Wireless Stick 64gb and I am still unable to connect to my device from my iPhone 5 since I’ve updated it to IOS even while using LTE network.  What other solution is there so I can be able to use my device and transfered my media?  

I’ve already formatted the device and udated the firmware and contacted chat live support and searched online for other possible solutions.
