I recently got a 5G Gateway S1 TMobile Internet for my home. Using the Internet App and selecting DEVICES to see all devices connected started giving me a “Gateway error code:500”. I finally figured out this occurred when I connected my Amazon Kindle Fire HD8 to the internet. The internet connection is fine on the Kindle but the TMobile App gives the above error when trying to access the DEVICES option. If I turn off the internet connection on the Kindle the DEVICES option works properly again thru the app. We have 2 Kindles which this issue occurs so it is not an issue with the Kindle.
I am using the Internet App on an iPhone.
Has anyone else had this issue with the TMobile Internet App?
