Why? What happens that forces you to reset the modem/router?

I tried resetting my router, flashing the firmware, playing with QoS, adding a bunch of static IPs, changing WiFi channels, etc. but nothing worked.

The only temporary workaround is to reboot my router.

The comment about firmware is puzzling. The C7800 is a modem/router. Only your ISP can flash it.

 

Your subject says "reset" which is not the same thing as reboot. Which is it?

 

While many questions about routers are generic and could be answered anywhere, some things need specialist knowledge.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Cable Modems & Routers

You might like to search there for messages related to your problem.

I will ask the Netgear moderator to move your message.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

Check for various troubleshooting tips.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

What channels are you using? Auto? 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?

 

Has a power off for 1 minute then back ON with the modem been performed?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on computers and rest of network.

 

Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

What Firmware version is currently loaded?
Please post a copy and paste of the modems connection status page.

You have some Criticals and Warnings that the ISP needs to review and resolve. 

 

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.

This is NETGEAR Nighthawk C7800

It only affected my WiFi devices, but not anything hardwired. I tried resetting my router, flashing the firmware, playing with QoS, adding a bunch of static IPs, changing WiFi channels, etc. but nothing worked.

The only temporary workaround is to reboot my router. This has become very annoying.. If I travel for a few days, my RING disconnects on the same day and stop working until I am back and restart the router. This is really very frustrating as I am thinking about buying a new router (This router cost me around $370)!!

 

My wired devices NEVER disconnects. ONLY WIFI. I tried to open a ticket but it seems I am out of warranty as I bought this probably two years ago.

I looked at the event logs, I see the below data (I will delete my personal info like MAC addresses).. Do you think this is related? If not, then can someone please provide some guidance on what can I do as I am out of ideas.
