Nest router not obtaining IP from cable modem

[tree1334]

My Google Nest router stopped providing an internet connection this past Thursday. The cable modem was fine (connected it directly to a laptop using the same Cat5 that was connecting to the router and had great connection). I powercycled the modem and router multiple times. I ended up having to do a factory reset on the router (and subsequently every access point and Google device that it had been connected to for them to be able to rejoin). It worked fine until this morning, when the same thing happened again. This time, even a factory reset didn't work and I even tried a different Google Nest router (I have 3 3-packs). I finally pulled out my old Linksys router and connected it to the modem and it's working fine. Clearly not a modem connection issue. What's going on with my Nest routers? I invested a lot of money in them to have a solid mesh network that covers our whole house, and they've worked fine for the past year (I setup the mesh network last November).

Hi tree1334,

That certainly isn’t the experience we want you to have, and we apologize for the delay. A few questions: are you using a modem/router combo from your Internet service provider (ISP)? Which Google/Nest router are we working with? What device are you using to set up your network (iOS or Android)? Do you have the Internet on your modem?
 

You can do a sequential reboot of your entire network and see if that helps, or please perform a 2-minute power cycle on your entire network to re-establish the connection on your connected devices. Here's how: 
 

1. Disconnect the power from the modem.
2. Disconnect the Ethernet cable and power cord from the parent point.
3. Disconnect the power cord from the child points.
4. Leave everything unplugged for 2 minutes.
5. Connect the power cord to the modem then to your router and points.

Also, you can give these steps a try:

1. If you're using a modem/router combo, set that to bridge mode to avoid double NAT issues.
2. Make sure that there is minimal to no interference (concrete, bulletproof glass, metal, mirror, etc.) and the points are no more than two rooms apart.
3. Remove any special characters in your network name and password.
4. Turn off IPv6:
   1. Open the Google Home app.
   2. Tap the Wi-Fi coin  and then Settings.
   3. Scroll down and tap Advanced networking.
   4. Scroll down to IPv6.
   5. Toggle the switch off Toggle button off.
5. Change your DNS server into 8.8.8.8 on the primary and 8.8.4.4 on the secondary server. Hit the save/ floppy disk icon on the upper right.
6. Unplug the power from your Google Wifi devices for 2 minutes.
7. If the issue persists, try factory resetting your network. Take note that this will delete all network data.

You may skip any step that you’ve done already.

Let us know how it goes.

Best,

Dan
