Has a factory reset and setup from scratch been performed since last FW update?&nbsp;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.https://kb.netgear.com/24089/How-do-I-specify-the-pool-of-IP-addresses-assigned-by-my-Nighthawk-router

None of these are enabled - Armor or Smart Parental Controls or Traffic Meter. I have enabled smart connect though, however if i turn off it does helps me to reach to 400 mbps speed for 5 Ghz wifi n/w.Cable connection:&nbsp;&nbsp;&nbsp;&nbsp;Event log :&nbsp;Factory reset has been performed multiple times with netgear support.

Power levels on some channels are too high:

&nbsp;
Might try adding a coax line splitter or an inline attenuator to help lower the power.&nbsp;
&nbsp;
You have too many Correctables that should be zeros.&nbsp;
Be sure your using good quality RG6 coax cable up to the modem.&nbsp;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#M12853
&nbsp;
You have Criticals and Warnings that the ISP needs to review and resolve.
Have the ISP check the signal and line quality UP to the modem.&nbsp;Be sure the ISP provisions the modem correctly.
Might ask them to help you reduce the power levels on the line.&nbsp;
