2.4 GHz

When I got my Ring Doorbell 2 it would not connect to 2.4 GHz but did connect to 5 GHz with no problem. Today it hit me that I had turned 2.4 GHz off since it's a guest network. Today I turned it on and Ring accepted my password and went through the motions but in the end, it kept failing to connect with the 2 left lights flashing. I made sure my phone was on the 2.4 GHz network. I've checked my router and do not see anything out of order. Watching it carefully, the step where the install fails is when it is restoring my internet. The light is blue flashing up then goes to two white left lights flashing. However, I notice that the LTE symbol is still there and then the wifi symbol comes back after the two white left lights are flashing. The problem appears to be getting my wifi started back again on my phone.
