How do I add another node to my existing mesh WiFi system?

Additionally, a node that is not from Community Fibre may be added to your network so long as it will be set up as a child node and not as the parent node.

If I have a mixed mesh WiFi network with other mesh WiFi networks as child nodes, can I use WPA3?

Other mesh WiFi nodes may not support these security options, verify that other mixed Linksys nodes in the network support WPA3. Your devices must also support WPA3. It is highly recommended to leave the setting to default, otherwise your other child nodes will disconnect from the mesh WiFi network.

How do I add a wired child node to an existing parent node?

Learn how to add a wired child node using the LinksysSmartWiFi.com page.

How do I upgrade the Linksys SPNMX57CF-UK's firmware?

How do I manually upgrade the firmware of my Linksys SPNMX57CF-UK?

How do I check the node's current firmware version?

You can check it by accessing the Linksys app dashboard using an Android™ or iOS device. Then, tap on the menu icon and go to Network Administration. If you are using a computer, follow these steps.

Why can’t I log in to the web interface using “admin” as the password?

Once the node has an internet connection, the admin password changes to the default WiFi password printed on the product label.

How do 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.

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. 

When should I prioritize the internet connection for my device?

On the Priority page, a message will appear recommending that the Device Prioritization feature be turned OFF if the internet speed is 200 Mbps or greater since the bandwidth is sufficient for your devices. It is ideal to prioritize internet connection for your devices when the internet speed is lower than 200 Mbps.

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.

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 is configured and the status light is solid blue before you can use the Linksys app to manage your network.

Can I add non-Community Fibre child nodes?

Yes. So long as the Linksys Community Fibre node is the device connected to your modem. All other Linksys non-Community Fibre nodes can be added as child nodes.
