INSTRUCTIONS & INFO

Prenote info

The AT&T Cell Booster Pro has a maximum range of approximately 15,000 square feet. Device range will fluctuate based on walls and other obstructions. Actual range might be limited by factors such as building materials, obstructions, and connected device capability.

1. To improve voice quality, try moving the AT&T 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.

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 & C2 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.
