1. To improve voice quality, try moving the AT&T 5G Cell Booster Pro.

Note: You can purchase a Netgear Powerline to move the device to an area where coverage is needed, if it is too far from the router location. You can also purchase additional AT&T Cell Boosters to improve voice quality, up to 6 per address.

2. Ensure that you are on the AT&T Cell Booster Pro network, and not the Macro Network (which may have poor coverage). The 4G C1, 4G C2 & 5G LEDs will flash white when an active wireless user is using the AT&T Cell Booster Pro network, and will be solid white when the device is ready for use.

3. If your AT&T 5G Cell Booster Pro is connecting correctly, check your internet connection and that the minimum bandwidth requirements are met and that you are not experiencing any internet issues. The bare minimum is 25 Mbps minimum on downlink and 5 Mbps minimum on uplink. Recommended is 100 Mbps down and 5 Mbps up.
