App Works on Hotspot but Not Home Wi-Fi: What It Means

Do the test properly#

The test only means something if only the network changes. Use the same device, the same app and the same account.

Turn on the hotspot on your phone.
On the TV or streaming device, join the hotspot, as you would any Wi-Fi network.
Open the app and try to play something for a minute.
Switch the TV back to your home Wi-Fi and try again.

Samsung's support page lists a hotspot, an Ethernet cable or another Wi-Fi network as ways to test an app that is not working.

This table is our own editorial reasoning, not a manufacturer's diagnosis.

Hotspot	Home Wi-Fi	What it points to	Go to
Works	Fails	Your home network	Home network checks
Fails	Fails	Not the network. Look at the app, your account or the device	Fire TV: apps will not load
Works	Works	The problem has gone. It may have been temporary	Try again later, at the time it usually fails
Fails	Works	The hotspot is the limit, for example your mobile plan. Your home network looks fine	Nothing to fix at home

Work down the list. Stop when the app works.

Restart the modem and router. Amazon's order, in its Fire TV help: unplug both and wait 1 minute, plug in the modem first and wait about 1 minute, then plug in the router and wait about 1 minute.
Test another device on the same Wi-Fi. Open the same app on your phone while it is connected to your home Wi-Fi.
- If it fails there too, the problem is more likely the router or the internet line. Go to step 4.
- If it works there, only this TV has the problem. Forget the Wi-Fi network on the TV and join it again, and move the TV or the router closer. Amazon suggests moving a Fire TV and the router closer for a stronger signal.
Try a cable if your TV has a network port. Samsung's support page suggests testing with Ethernet. Samsung says that if the app works on Ethernet, the problem may be the TV's Wi-Fi.
Look at your router settings (see the box below).
Check the TV's DNS setting. Samsung's Australian support page lists setting the DNS by hand as one of its steps when an app does not work. Write down the current settings first so that you can change them back.
Turn off any VPN on the TV or streaming device for one test.
Ask your internet provider. If nothing in the router explains it, ask your provider whether they filter or block that service on your line.

Note what you tried and what changed. Include the router model and the exact message on the screen.
Send those details to the app's support, and to your internet provider if the hotspot test pointed at your home network.
