MR60 solid amber light and no Wifi

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between MR and MS🛰️ to

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 ISP modem and router been performed since last update?
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 the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Please post a copy and paste of the modems connection status and event log page.

UPDATE: I did a new factory reset, this time following the exact process I went through during initial setup of this router. It worked! Not unexpectedly, I must have screwed up the first factory reset.

I'm still curious what happened. The Sonos systems are still disabled, so I wouldn't mind hearing if anyone else has had issues with those in particular.

Good day!

I posted earlier this year about a problem which may or may not be related to my current one, which just began on Thursday. (Prior post: https://community.netgear.com/t5/Nighthawk-Wi-Fi-6-AX-Mesh/MR60-solid-amber-light-and-no-Wifi/m-p/2297216#M226866)

SETUP: Netgear CM1100 modem connected to desktop computer and Netgear MK63 Wifi-Mesh router system. MR60 router is next to modem in same room as desktop; two MS60 satellites are in separate rooms, approximately 15' and 45' away, all on the first floor. Wifi typically accommodates my work laptop, work iPhone, personal Android cell, personal Samsung tablet, HP printer, and Sonos music system. Since prior issue in February, Wifi has been working relatively well, with the sole exception of occasionally seeing much lower download speeds in room with the router than in room next door (which has a satellite).

CURRENT PROBLEM: Wifi abruptly stopped Thursday afternoon. Router shows solid Amber light; devices showed "connected, no internet". Ethernet connection to desktop computer works fine.

WHAT I'VE DONE:

1. Power-cycled router twice, then power-cycled modem separately, then power-cycled both of them together at least 3 times. No change.

2. Factory reset of modem and router. No change.

WHAT I HAVEN'T YET DONE:

1. Update firmware manually. I have downloaded the necessary files but will note the firmware version on the router is current when I was able to check it on Friday.

2. Cleared event logs. I have attached the modem's event log page but have yet to clear it.

POTENTIAL CLUE? When I hooked up my work laptop directly to the modem (basically unplugged the cable that had gone from my desktop to the modem and plugged the computer end into the work laptop's dock), I cannot connect to the internet. I got a message saying there was no valid IP address. I cannot rule out the possibility that there is an issue with either the ethernet adapter on that laptop or the dock somehow, though. (Dell Precision M5560 with Thunderbird dock)

Attached is the event log from the modem I will attach the cable connection info in separate posts, since it seems to limit me to one attachment per post. Any ideas? At this point, I can't even confidently say whether it's the modem or the router that has the problem.

Thank you for any assistance you can think of!
