Cable modem will not connect to the internet after power outage

[egret]

I am having trouble with my Orbi CBR 750. When the power is interrupted at my home the wifi system will not show it self and reconnect to my devices until I reset the modem through Xfinity and turn the router on and off several times. When I run the xfinity troubleshooting app it states that there is no issues and the lights are all white on the modem. It seems like the wifi gets turned off by the power outage? Is there a way to stop this from happening? It is difficult when I am out of town. Thanks for your help.

Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.
