You should keep The Hub some company by placing it close to your router. The issue might be caused by the Devices being too far away from each other. Get ‘em closer! It will help The Hub pick up some signal.
Now, if you’re setting up your Kit for the first time, you might want to double-check that Wi-Fi password. Can’t find your network? That could be because The Hub only connects to 2.4 GHz Wi-Fi signals. If your router has an option for 2.4 GHz and 5 GHz, be sure to use the 2.4 GHz.
If Wi-Fi isn’t happening, it might be best for you to leave The Hub connected to Ethernet.
