I got a new modem yesterday. I plugged it in and tried to set it up with the xfi app. Needed help and the chat person said it was activated and I had customized it. I didn’t customize it it just copied my previous modem settings and passwords. I had a 2.4 and a 5 network. The app told me to combine the hem and it would auto select for me. It show lots of devices on the network but those devices don’t have service. Help please.
