FIRMWARE UPGRADE
You can set up the router to automatically upgrade the firmware or you can upgrade it manually.
You can do either of the following:
- Log in to the Linksys app, tap the menu icon, and then tap on Network Administration > Nodes. Then, tap on your router and look for Firmware Version.
- Log in to the router's web interface and go to Router Settings > Connectivity > Basic. Click the drop-down arrow next to Details in the Firmware Update section and look for Current Version.
ADVANCED TROUBLESHOOTING
After you have finished setting up your parent and child nodes through the Linksys app, the child nodes will need a few minutes to connect. Once the child nodes are connected to the network, they will have a solid white light. The app will also update each node's status after the connection is made.
To set up your routers as child nodes, make sure that they are near the parent node (router connected to your modem), within 10 ft of distance. If possible, put them in the same room as the parent node. Once they have been added, you can move them to other locations as needed.
To reset the router, press and hold the reset button for about 10 seconds. The light on the front of the router will flash bright red, then it will dim out in three pulses, followed by one last bright red flash. Once you see the longer red flash, release the reset button and wait for the router to boot up.
You can access the dashboard through the Linksys app on a mobile device or the router's web interface on a computer.
If you are using another router that supports a USB drive, you must connect the drive to the router that is in parent mode. The External Storage feature is only supported when the router is in parent mode. It is not supported when the router is in child mode.
Yes. It supports IPv6 RD and 6to4 tunneling.
