If the Harmony Ultimate Hub isn't connecting to Wi-Fi, try the following:

• Unplug the power adapter from the hub and then plug it back in to reboot it (the hub takes about 30 seconds to reboot).

• Confirm that you entered your router's correct SSID (your Wi-Fi network's name) and password.

• Confirm your Wi-Fi is working by using another device and making sure it connects.

• Move your hub so that it's in range of your router, and remove obstructions that might be causing interference.

• Make sure your network meets the minimum requirements (see answer 360023257754).

• Power cycle your router by unplugging the power adapter and plugging it back in.

• Make sure your smart device is connected to the 2.4GHz frequency on the router, as Harmony Ultimate Hub isn't compatible with 5GHz.
