Orbi RBK753S cannot obtain IP address

I tried resetting the router to factory settings and setting it up as a new network. I recreated the same network name as had previously existed with the same password and all my devices immediately connected. I still have no idea why the restart that occurs when power is cut off and restored causes device connections to fail because of an inability to get an IP address but I'll try to figure that out later. However, I ran into another strange situation. My phone was connected to the new network but the list of wifi networks contained a second entry with same network name with a label stating "Available via Orbi." I figured this was left over from the previous network of the same name so I selected the entry with the intention of forgetting it. The only option when I selected it was Connect and, when I tried that, the connection failed and the label now showed "Available via Orbi. Reset password and try again." Selecting the entry still gave only a Connect option, no password entry screen appeared, and the entry failed. This is now the only entry for my network in the list of available networks so I cannot connect my Android phone to wifi. I don't want to reset and reinstall the router all over again- can you tell me how to connect my phone to the wifi network?
