Netgear Night Hawk CM1100 does not work with Google Nest Wifi, any guidance? Xfinity gigabit plan
Hi everyone, Asking for some desperate advice here as I have spent the entire weekend googling and reseraching, and still have no luck. I got the brand new Netgear Night Hawk CM1100 (DOCSIS 3...
I have the same problem. I successfully added my Google wifi to the CM1100 and it was working fine. I was having some speed problems with my ISP (Cox) and the ISP performed a "hard line" reset of the router (not a mere power reset). It fixed my speed problems but my Google wifi would not connect to the internet, eventhough it is directly wired to the LAN 1 connection. I ran through the troubleshooting posted on the Google help site and other forums (disconnect power to the modem and wifi, wait a few minutes, reconnect power to the modem, once the modem is operating fully, connect power to the Google wifi). I have completed this procedure several times with no success. My devices are connected to the wifi but cannot reach the internet.
From all of the community forums I have read, this appears to be a problem with the CM1100 modem, not the Google wifi. If I cannot solve this, I plan to return my modem since I have not seen posts that indicate similar problems with other modems. That would be a shame.
Any help on this is greatly appreciated!
Have the ISP check the signal and line quality UP to the modem. Be sure they have provisioned 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.
https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853Power OFF the CM modem and connect 1 wired PC or laptop to the WAN port #1. Remove wifi router for now. Power ON the modem. Check to be sure the computer gets internet services here.
