Status lights during firmware upgrades
Firmware updates keep your Wi-Fi gateway running smoothly. During the software installation, you’ll lose internet and phone service. The lights will function as follows:
- As firmware is being loaded into flash, the lights will operate normally as described.
- The installation will take a few minutes. During this phase, the Power light will be solid green, the Ethernet light will be solid green, and the rest of the lights (Wireless to Phone 2) will flash solid green one after the other moving from top to bottom and then bottom to top.
The gateway will restart automatically. As the it restarts, the POWER ON light behavior will happen.
