Devices cannot connect to WiFi

If your devices are not connecting to the WiFi, check the following:
Verify the WiFi password
Make sure you are entering the correct WiFi password. The WiFi password is case-sensitive. Change or verify your current WiFi settings using another device that can connect, or connect a desktop computer to a child node’s Ethernet port.
Verify your Wireless Security Mode
Some older client devices may not support WPA3 Personal. If they cannot connect to the WiFi network, try changing the security mode to WPA3/WPA2 Mixed Personal or just WPA2 Personal to restore compatibility.
Avoid outdated QR codes
If you used the QR code from the web interface or the QR code from the bottom of the Linksys node you saved during initial setup, and you have since updated the WiFi password, you will need to log in to the router and download a new QR code with the updated WiFi password. Learn more.
Adjust Instant-Privacy settings
Some WiFi clients can’t reconnect to the WiFi. If you have enabled Instant-Privacy on the Linksys router, your device may have MAC address randomization enabled and therefore will not be able to connect because it's using a different MAC address. Learn more.
Check connection status and physical switches
Child nodes (blinking red light) and/or all WiFi clients can’t reconnect to the network. If your router supports an external Privacy toggle switch, it may be in the lock position. Change it to the unlock position, wait, and check if the child nodes and wireless clients reconnect to the WiFi. This can happen if the router was ever powered OFF and the Privacy toggle switch was set to the lock position. Learn more about Instant-Privacy.
