If after testing your connection speed you have determined that the difference is too big for you and imposes on your normal internet usage, you may use these steps to troubleshoot the issue for your Fire OS device:
- Try different VPN servers. The closer the server to your location physically, the better the speed.
- Try switching between wired connection (Ethernet) and Wi-Fi.
- Try reinstalling the Atlas VPN application on your device.
- Try changing the connection protocol for your Atlas VPN application:
For Fire OS, please head to Atlas VPN application Settings -> VPN Protocol -> IPSec/IKEv2 or WireGuard to see which one produces better results.
