What are the default settings of the node? Below are the default settings of the node:
 
  • The default IP address is 192.168.1.1. If the upstream device uses the same IP address, the node will automatically use a different ethernet (LAN) IP address to avoid any conflict.
  • Administrator password:
    • The default password is the default WiFi password located on the product label of the Linksys SPNMX56CF when using the Linksys app for the first time.
    • If you're going to access the router via a web browser and you have not customized the router password, you need to click Reset password to create a new one before you can log in.

ADVANCED CONFIGURATION
How do I check a node's current firmware version?
Can I manually upgrade the firmware on the node? No. The node only supports firmware from Community Fibre which is automatically installed.
How can I reset the node to factory defaults? To reset your node to its factory defaults, press and hold the reset button until the light on top of the node turns red, fades, and flashes bright red.

IMPORTANT: Make sure that a bright red flash, followed by three to four quick faded red pulses, and then another bright red flash occurs before you release the button.
How do I recover my admin password? You can recover the admin password through the five-digit recovery code printed on the product label at the bottom of the node.
What is Dynamic Frequency Selection (DFS)? Dynamic Frequency Selection (DFS) is a spectrum-sharing mechanism that allows multiple wireless local area networks (WLANs) to coexist with radar systems. It automatically selects a frequency that does not interfere with certain radar systems while operating in the 5 GHz band. The benefits of using DFS channels are less WiFi interference and better WiFi performance.
How do I enable the DFS feature?
Can I use DFS in my network with other routers on child nodes? Yes, but only if all your child nodes support DFS. If your other child nodes do not support DFS, the child nodes will not be able to connect to your network.
Can my clients connect to the DFS channels? Yes, but only if your clients support DFS channels. Clients that do not support DFS channels can connect to the 2.4 GHz band instead.
Can I set up the node using the Linksys app? No. The node supports ACS. This means it will begin to self-configure when the node is connected from the internet port to the Community Fibre equipment. Click here for setup instructions.

DO NOT try to set up the parent node with the Linksys app while the node is going through the ACS setup because the Linksys app will not detect the node. Wait until the node self-configures and the status light is solid blue, only then can you use the Linksys app to manage your new Linksys network.
Can I add non-Community Fibre child nodes? They will work depending on the ISP firmware features. Contact Community Fibre for more information.
