Your router can broadcast on different wireless channels. If your neighbour's router is using the same channel as you, this can interfere with your signal and cause some problems.
How to Change the Wireless Channel on Your Router to Improve Wi-Fi Signal
Changing the wireless channel on your router can significantly improve your Wi-Fi connection by reducing interference. For more tips on optimizing your connection, see our comprehensive Wi-Fi guide.

Understanding Your Zyxel VMG 8924 Router
The Zyxel VMG 8924 router is dual-band, offering two wireless frequencies: 2.4GHz and 5GHz. The 5GHz network typically provides a stronger signal and is less prone to interference. You can identify these networks by their names; the 5GHz network includes "5G" in its SSID. For example:

We recommend using the 5GHz network whenever possible for better performance. However, if your device doesn't support 5GHz or you're too far from the router, connect to the 2.4GHz network.
How to Change the Wi-Fi Channel for 2.4GHz and 5GHz
You can change the channel for both 2.4GHz and 5GHz bands on the VMG 8924 router, or only for the 2.4GHz band on the VMG 8324 router. Follow these steps:
- Connect to Your Zyxel Router
Use an Ethernet cable (recommended) or connect via Wi-Fi.
- Access Router Settings
Open a web browser, type 192.168.1.1 in the address bar, and press Enter.
- Login
Enter the username admin and the password 1234 (or your custom password). If the password doesn't work, contact our Technical Support team at 01482 606101 or via Live Chat.
- Navigate to Wireless Settings
Select Network Settings and then Wireless.
- Select the Frequency Band
For VMG 8924, choose either 2.4GHz or 5GHz from the Band setting.
- Change the Channel

I'm changing the channel for 2.4GHz
This band is usually set to auto. To reduce interference, try channels 1, 6, or 11. If issues persist, experiment with other channels, avoiding channels 12 and 13 in the UK.
-
I'm changing the channel for 5GHz (VMG 8924 only)
Start with channels like 36, 40, 44, or 48. Some devices may not support channels above 50.
-
- Apply Changes
Scroll to the bottom and click Apply. Test your connection; it may take 15-20 minutes to see improvements.
You may not notice immediate changes. Test each channel for at least 15-20 minutes before switching. Monitor the signal strength and adjust the channel if necessary.
