ADVANCED CONFIGURATION


1.  How do I upgrade the node’s firmware?

It is highly recommended to use automatic updates.  The node has a feature that automatically updates the firmware which is enabled by default.  You can click on the Check for Updates button in the LinksysSmartWiFi.com page to see if a new firmware is available for the node.

2.  How do I check a node's current firmware version?

The firmware version can be found in the Linksys app on the Network Administration screen.  To access the Linksys app, follow the instructions here.  Then, tap on the menu icon and go to Network Administration.


3.  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 then another bright red flash occur before you release the button.


4.  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.  To learn more, click here.

5.  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.

6.  How do I enable the DFS feature?

To learn how to enable the DFS feature, click here.

7.  Can I use DFS in my network with other routers on child nodes?

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.

8.  Can my clients connect to the DFS channels?

Only if your clients support DFS channels.  Clients that do not support DFS channels can connect to the 2.4 GHz band instead.

9.  How do I access the Linksys app dashboard?

To learn how to access the node through the Linksys app, click here.

10.  How do I access the node's LinksysSmartWiFi.com page?

To log in to LinksysSmartWiFi.com, open a web browser, enter "https://myrouter.local" in the Address bar, and press [Enter].  You may also use the node’s default IP address which is "192.168.1.1".  If you have set up an IP address for the node, use that specific IP address.  To learn more, click here.

TROUBLESHOOTING


1.  Can I set up the node using the Linksys app? 

No.  The node supports ACS.  This means when the node is connected from the internet port to the Community Fibre equipment, it will begin to self-configure.

NOTE:  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 can you only then use the Linksys app to manage your new Linksys network.


2.  Can I manually upgrade the firmware on the node?

No.  The node only supports firmware from Community Fibre which is automatically installed. 

3.  Can I add non-Community Fibre child nodes?

They will work depending on the ISP firmware features.  Contact Community Fibre for more information.

4.  Can I use the Linksys MX5500 firmware to update the node?

No.  If you attempt to manually update the node using Linksys MX5500 firmware, it will reject the update.

5.  My Linksys mesh router isn't working with my ISP's 5G router. What should I do?

For the Linksys mesh router to work with a 5G router, your ISP must provide a 5G router with an ethernet port for connection to the parent node.
