Twice in the last two days this has occurred. My router will stop providing internet access to all devices, wired and wireless. Restarting the router via the power button restores access. My gateway (192.168.0.1) is pingable during this time, but trying to access the web UI times out. I dont use QoS, geoblocking, etc. Firmware VersionDumaOS Version1.1.0.22_2.1.343.3.687 I really like the router for the most part, but working remotely I really need the device to stay stable. Especially since a restart takes like 2-4 minutes for the access to be fully restored. My DHCP range starts at .50 which i've also seen mentioned elsewhere so i dont have DHCP competing with any reservations I wish i could provide logs, but they get wiped out after i power off / on the router, and the web UI is inaccessible during the issues.

Does the Internet LED on top turn AMBER when this happens? What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended. Has a factory reset and setup from scratch been performed since last FW update?

It does not, the internet LED remains white. The router simply becomes unresponsive to clients although it can still be pinged.I'm using Shielded CAT 8 from modem to routerMy Modem is a Netgear Nighthawk CM1200I purchased the router maybe 1 month ago. It was already factory reset and then I updated the firmware to the latest

What devices do you have all connected to it? What is the default DHCP IP address pool range now? I recommend using .100 thru .200. How is the WiFi settings configured? Basic and Advanced menus please. Can you please post the following from the CM modem: Please post a copy and paste of the modems connection status and event log page.https://kb.netgear.com/30007/How-do-I-obtain-the-cable-connection-information-from-a-NETGEAR-cable-modem-modem-routerhttps://kb.netgear.com/30008/How-do-I-view-or-clear-the-event-logs-on-my-NETGEAR-cable-modem-or-modem-router Be sure to disable any MAC Address randomizers on phones and pads while at home:https://community.netgear.com/t5/Nighthawk-App/NETGEAR-Mobile-Applications-and-Apple-Devices-FAQ/td-p/2220015/jump-to/first-unread-message

I'm using 192.168.0.21-254. I dont use any DHCP reservations, nor would an IP conflict cause my entire network to lock up;Also keep in mind this impacted both wireless and wired clients. My last lock up occured around 9:10am CST. Looking at my modem logs which i believe are in UTC, i do not see any events around that time. Cable Connection Stats (Keep in mind i did not have to restart modem to resolve issue):

Please try DHCP IP address range .100 to .200 on the XR router. 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. Signal Power is too high on the modem. You'll end up burning it up: https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router I see lots of correctables and un-correctables that should be zeros. 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.https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlhttps://highspeed.tips/docsis-events/
