How do I change the wireless channel on a Zyxel XMG 3927 & Zyxel EX5401 router?

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.

For details on how to change wireless channels on other routers, please see How do I change my wireless channel?

Changing the wireless channel on your router may help improve your wireless connection, but it could potentially cause more issues while band-steering is enabled. For this reason, we recommend turning off band-steering first by following these instructions.

First, some things you need to know

• The Zyxel router is dual band which means that it has two wireless frequencies as usual: 2.4GHz and 5GHz. However, as band-steering is enabled by default, you'll only see one wireless network to connect to.
   
• Changing the wireless channel while band-steering is turned on isn't recommended as you're not going to know whether this has fixed the problem - the router could end up pushing all devices onto the other band to compensate.
  
  For help turning off band-steering, see this article.
   
• We highly recommend using the router's built in Wi-Fi Analyser so you can choose a channel with the least interference.

How to change the wireless channel

1. Connect a device to your Zyxel router using an Ethernet cable (recommended) or Wi-Fi.
   
   
    
2. Open a new web browser and type 192.168.1.1 into your address bar and press enter or go.
   
   
    
3. You should now see a Zyxel screen asking you to Login - we'll explain where to find these details in the next step.
   
   
    
4. To log into your router, you're going to need the username and password which you can find on the little card that comes with your router. This is normally located on the slot on the back.
   
   
   
   Type in the username and login password, then select Login.
    
    

   Password not working?

   If this password doesn't work, you'll need to factory reset your router. To do this, find a pin and push it into the 'Reset' hole on the back of the router for 10 seconds. After a few minutes when your router has turned back on, go back to Step 1.

   
   
    
5. Once you're logged into the router, you'll see the Home screen. This is where you get an overview of what's happening on your router. At the top right of the screen, select the three black lines to open the Menu.
   
   
    
6. Select Network Setting and then Wireless.
   
   
    
7. A page labelled Wi-Fi will open. Make sure you're editing the right Band (2.4GHz or 5GHz) and then look for Channel in the Wi-Fi Network Settings section. Change this to a different channel number, then click Apply at the bottom.
   
   
    
8. The wireless channel will now be changed for that band.
