Netgear C6250 Connection Keeps Dropping

Hi, the guy at the xfinity service center and the people on netgear customer support and both proving to be useless in helping me with my new modem/router combo. I am experiencing intermittent drops with my connection with the network still being up but no connection to the internet.
The xfinity guy keeps saying there’s no issues.
My event log keeps saying critical and notice and warning, of things like: WiFi Interface [wl1] set to Channel 36 (Side-Band Channel:N/A) - Reason:INTERFERENCE
