Key Features of Recent Updates Recent optimizations for the F670 series firmware include: Enhanced Data Flow
: Never flash firmware over a Wi-Fi connection. A sudden wireless drop during installation can permanently corrupt the router.
Prevents ISP from pushing re-locks.

Hey everyone,
It is normal for modern, high-speed routers to feel warm, but not so hot that it is painful to touch or causes the internet to drop. 2. Will updating the firmware void my warranty?
Ensure the modem is standing vertically on its stand, not lying flat. Vertical orientation allows better airflow.
Ensure the router has at least on all sides for airflow. Keep the router dust-free using compressed air.
