If a child node keeps losing connectivity to the network, try the following:

• The child node may be too far from another node; try moving the child node closer. Learn more about signal strength in the LinksysNOW web interface. 
• If you have several child nodes in the network, try rebooting the Linksys parent router that is connected to the modem.
• Do you have any specific WiFi features turned on, such as MLO, DFS, or MAC filtering? Try turning off one feature at a time to isolate the issue. To disable these features, check this article.
• If none of the above resolved the problem, and if you will be calling Linksys support, please help us provide the following information:
  • How often do you notice the disconnections? (twice a day, a few times a week, etc.)
  • Do the nodes reconnect on their own, or do you have to reboot the parent or the child node to temporarily resolve the issue?
  • If a child node reconnects on its own, how long does this disconnection last?
  • When this issue occurs, what are the initial observations?
  • What color is the child node LED? Is it blinking or solid?
  • Do you have any wired clients on any of the child nodes?
