Slower than expected download speed.
The devices I'm linking to are located nearby, and I'm unsure if AT&T reduces priority for gaming data.
Ensure all games run smoothly for 600ms or longer. Verify no other devices on your network are transmitting data to the internet. If none are detected, review your router's settings. When QoS is active, consider disabling it to test performance improvements.
I can provide general guidance, but I haven't used that particular gadget before—so I can't offer tailored advice. You should visit your router's IP address in your web browser, typically at http://192.168.0.1 or http://192.168.100.1. If those don't work, open a command prompt and run "ipconfig" to see the details. Look for the default gateway listed there; it might be different from the example shown. After accessing it, enter your router's login credentials—defaults are usually on the label underneath, but if changed, contact your network administrator. Once inside, search for settings related to quality of service or network prioritization.
