If you are using a CBN CH8568 rental modem from SimplyNet, it will arrive with a default Wi-Fi network name (SSID) beginning with CBN-, and a default password printed on the modem's sticker. Many customers prefer to customize both after receiving the modem. Here's how to do it.

📡

Applies to: CBN CH8568 modem. If you have a Sercomm DG4244, see this guide instead.


1. Connect to the Network

Connect your computer or smartphone to your CBN network by Wi-Fi or Ethernet cable (Ethernet is recommended for modem configuration).


2. Access the Admin Portal

In a browser, navigate to the modem's web interface: http://192.168.0.1


3. Log In to the Admin Portal

Locate the sticker on the side bottom of your modem. Find the Username (cusadmin) and Password (the admin password — this is different from your Wi-Fi password). There are two stickers on these modems, make sure you are looking at the correct one


4. Click Wireless


5. Click Security


6. Change the Password (and Network Name)

  • Locate the Wi-Fi Password (or security key) field the 2.4 GHz or 5 GHz network (or both) and enter your new password.
  • Optionally, edit the WiFi Network Name (SSID) to something more personal.


7. Click Apply Changes.


That's it! Note that all connected devices will disconnect once you save the new password, and you will need to reconnect them using the new credentials.
