Trouble with 5G Band on Nighthawk AC3200 WiFi Cable Modem Router (C7800)

My modem/router LED light shows that the 5G radio is on - sometimes solid and other times flashing intermittently.  My devices all show that the 5G band network is available.  The same is true for the 2.4G band width other than the LED light constantly is flashing.  The 5G is intermittent with allowing devices to connect but usually with no internet connection, when it occasionally does connect with internet connection is is very slow and usually "in and out" and then losses internet connection completely.  I have disconnected the modem/router power for a few minutes and then reconnect to power to restart.  I have disconnected and reconnected the internet ISP cable.  I checked the Net Genie and find that the ISP, Sparklight Internet, and it shows that they pushed the latest firmware version, V6.01.07.  Everything I can see on this browser site shows the modem/router to be working properly.  I do not know how to further troubleshoot the modem/router which has been functioning properly since late September 2021.  Sparklight pushed a "hard signal reboot" to the modem/router and that didn't work either.  How do I discern if there is a problem with the Sparklight signal coming to the modem/router, if the router is failing, or if it may be an IP address issue originating with the modem/router signal being broadcast?

      I am not exactly a computer tech guru.  I don't recall which channels the two were set up on but I do believe that they were both set to the same channel.  I have no idea how to tell if the Smart Conect is enabled or disabled but can follow most instructions to check if providerd.  I was able to find that Sparklight had pushed the most current firmware version to my modem/router.

       

      If I try to do a factory reset followed by a fresh set up will that cause the Firmware version to revert to an older version?  I only ask because I learned through research on this forum along with verifying on the website that the firmware updates have to be pushed by ISP providers who don't like to do it because of associated cost.

       

      Your assistance if greatly appreciated, thank you.
