Nighthawk c7000v2 Connection Drop (ISP: XFINITY)
Hi Everyone -
I've been facing an ongoing problem since I switched to the NETGEAR nighthawk modem/router. I keep losing connection every hour or every 30 minutes. Whenever I try to connect to the wifi, it would say no internet available. I have reached out to both parties and it goes nowhere. NETGEAR tells me to update the firmware and XFINITY said they can't since the modem isn't their own. It's pretty much been a back-and-forth issue with the firmware stuff. Reached out to XFINITY and everything is good on their end. They're assuming it might be a network issue but I don't know anymore. Please help

How is the Wifi Basic and Advanced settings configured on the modem?
What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?Does same thing happen with wired devices?
What devices do you have connected to the modem?
Please post a copy and paste of the modems connection status and event log page.

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.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlOnly ISPs can update FW on C series modems. Some may have there own policy's that say they won't update user owned modems.
