AC1750 (C6300) suddenly dropping wifi connection on ALL devices
Bought this dual model/router in early 2020. It's been working fine ever since. Last weekend, we installed a new Nest camera and ever since then (coincidence?) the wifi signal has been dropping on AL...
Thanks for your reply. I have powercycled the modem a couple times before and it did not help previously.
Last time, I took the channels off auto and I selected 9 for the 2.4G (because 1, 6, and 11 were heavily used) and 149 for the 5G. I've attached the images below. I live in a townhome so there are a number of competing neighbors, at least 11 - 18.
Currently, it seems the latest fix is holding without any disconnections -- which was yesterday I reset to factory and kept the default network names ("Netgearxx") as well as found a less congested channel.
I recommend you change to channel 11 since theres only 1 and 48 or 161 since nobody is using that channel. I guess you can use channel 9 however it's not recommended has its not a primary channel. See how it works for you though.
Thank you for the advice. It has now started disconnecting intermittently at the rate of every couple minutes. Here is the event log. I don't know what to make of it. Please advise!

Please post a copy and paste of the modems connection status page.
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.
Be sure to power OFF the modem for 1 minute them back ON.
