Nest Router not seeing dhcp wan connection

[Dan86]

Hi,

im wondering if you could help me please.

I've used a google nest WiFi setup for around 12 months now with no issue.

My home internet connection was FTTP 100/40 DHCP.

I have just changed ISP and my new connection is FTTP 1000/50 DHCP.

Using my iPhone via the google home app.

I factory reset the entire google nest network and plugged the router straight into the FTTP port. 
I can see the device, I can join its WiFi, I can scan the QR code but it will not accept the new DHCP connection. It times out.
I also have access to a Ubiquiti UXG-PRO and Netcomm NF18ACV. Both of these routers were factory reset and are setup to DHCP on wan port. As soon as I take the cable out of the google nest router and put it into either of the other routers, I get internet straight away?

I take the cable out and put it back into the nest router and cannot get the wan config to accept the DHCP internet?

I have reset the Google nest router 3 times and get the same issue.

What am I missing? Any help would be greatly appreciated.

Thank you,

Dan

Hi Dan86

Thank you for posting in this community. I can offer some troubleshooting steps to help you solve this situation.

Make sure that you are using the correct steps to set up your wifi router. 

1. Connect the Ethernet cable to your Nest Wifi router's WAN port . Then connect the other end to your modem.
2. Follow these steps about how to change the WAN settings, you can view your WAN IP address and configure settings using one of the connection methods (DHCP).

Hello, thank you for your response, however it did not work.

i am not trying to change my wan settings from dhcp to static or ppoe, my problem is the best router cannot pick up my new dhcp connection.

Hey! Dan86

Here are a few more steps you can try:

Double-Check Google Home App: Make sure the Google Home app is updated to the latest version. Outdated versions might have bugs affecting network setup.

Check ISP Configuration: Contact your new ISP and confirm there are no specific configuration requirements for connecting routers. Some ISPs might require user intervention or specific settings for DHCP to work properly.

Disable Firewall (Temporarily): If comfortable, try temporarily disabling the firewall on the Google Nest Wifi in the app. This might be interfering with DHCP negotiation (be sure to re-enable it later).

additional tip: Since other routers work with your new connection, you have a fallback option. You could use the Ubiquiti UXG-PRO or Netcomm NF18ACV as your main router and put the Google Nest Wifi in bridge mode (if supported) to utilize its mesh functionality.

By trying these steps, you should hopefully be able to get your Google Nest Wifi working with your new DHCP connection. If not, Google Support can provide further guidance.

Let me know how it goes.
