The satellite routers on my mesh network aren’t connecting #
Make sure that your satellite devices are powered up and turned on. If they are, trying unplugging and replugging the problematic device and see if it will connect to your network then. If your router app allows you to restart a Wi-Fi point (Google’s Home app, for example, allows this), then reboot that point and see if this helps too.
Google also allows you to run a test to make sure the network is set up properly. You can find Wifi points on the Home app, under Test mesh. If the test comes back with a weak or failed connection, you should try repositioning your satellite routers to be closer to your primary router. This is also a good tactic for any mesh system that keeps dropping its satellite points — they could be too far away from the primary point.
You can also double-check to make sure that your satellite router devices have a different SSID than your primary router. If they were accidentally all assigned the same SSID, then the mesh network may not be able to coordinate properly.
If your router still seems unable to connect, then make sure that nothing significant has changed for your network settings. For example, if your ISP WAN (wide-area network) type changed for some reason, you may have to go back into settings for the router and make sure that the right WAN setting is chosen.
There are additional special cases where certain Wi-Fi technology can interfere with mesh networks, so it’s also a good idea to contact router support directly and explain your situation if nothing is working.
