How do I set up the Adtran 841-T6 router?

Written by Editorial Team | Last Updated: August 2026

Setting up the Adtran 841-T6 Service Delivery Gateway begins by placing the unit on a flat, open indoor surface near a power outlet and connecting the included 12V DC power adapter to an active electrical wall socket. Next, take an Ethernet patch cable—typically connected downstream from your fiber optic ONT—and plug it securely into the 2.5G WAN port located on the rear panel of the gateway device. Allow a few minutes for the system to boot up, synchronize with your internet service provider, and transition the status LED indicators to a solid green state. Finally, connect your computers via Ethernet or join the default Wi-Fi network name printed on the device label using the pre-configured wireless security password.
