Unable to Connect - Grill Cannot Connect to Network - D2 Notification

This article explains how to resolve the problem found when pairing an iPhone, 

There are two common causes for Unable to Connect - Grill Cannot Connect to Network:

1. Incorrect network password
2. Trying to pair to a 5GHz network.
   
   

Cause 1: WiFi Password

WiFi network password or grill information was entered incorrectly.

Resolution

Verify that your home WiFi network name and password are correct.

Cause 2: Network Frequency

The grill is attempting to connect to a 5GHz home WiFi network rather than a 2.4GHz network.

Resolution

Many modern routers broadcast on both 5GHz and 2.4GHz bands. Verify that your WiFi network that your grill is attempting to connect to is a 2.4GHz network. Two factors may be causing this confusion:

1. The network name does not always reflect which frequency is being used.
2. Some routers allow 2.4GHz and 5GHz networks to be given the same name. Regardless of the network name, your grill and phone must be on the same network. If your phone is on the 5GHz network and your grill is looking for a 2.4GHz network of the same name, they still won’t pair because they’re not on the same network.
