Why does my ZyXEL Communications NBG4604 Network Router have low signal strength?

T
tinaduncanJul 31, 2025
Low signal strength on your ZyXEL Communications Network Router can be caused by several factors. Interference from objects or other equipment, thick walls, reflective surfaces, the router's position, Bluetooth devices, or placing the router in an enclosed space can all contribute to this issue. To resolve this, try moving your router to a common area, ensuring it's away from walls and metallic objects, keeping it in an upright position and not on the floor, turning off Bluetooth devices one at a time to check for improvements, and making sure it's not in an enclosed space.

How to improve signal strength on ZyXEL Communications NBG4604 Network Router?

To improve the signal strength of your ZyXEL Communications Network Router, consider these points: avoid placing the router in an enclosed space or next to metallic objects, microwaves, cordless phones, or RF transmission devices. Ensure the router is in an upright position and not on the floor. Thick walls can also weaken the signal, so position the router away from walls. Experiment with turning off Bluetooth-equipped devices to see if that improves the connection. Moving the router to a common area, like a living room, may also help.
