Google Nest Wifi With Vodafone: How to Set It Up Properly (and Fix Double NAT)
12 November 2026 · By Ethan Fernandes
Double NAT or devices dropping with Google Nest Wifi and Vodafone broadband? The right setup for this combination, whether to keep the Vodafone Hub, what full fibre needs, and how to protect your home phone.
Quick fix
The Vodafone Hub has no modem mode, and Google Nest Wifi only supports one unit in bridge mode. On full fibre, the best option is to connect the Nest Wifi straight to the Openreach fibre box (PPPoE, login from Vodafone), as long as you don't need the Vodafone home phone. Otherwise keep the Nest Wifi as the router behind the hub, turn off the hub's Wi-Fi and use its DMZ setting.

Get help todayYou've added Google Nest Wifi to your Vodafone broadband and it isn't quite right: the app warns about double NAT, games report strict or moderate NAT, a work VPN drops, smart devices disappear, or phones hop between the Vodafone Hub's Wi-Fi and the Nest Wifi. The cause is that both are acting as the router. Here's how to set up this exact combination properly.
The short version: The Vodafone Hub has no modem mode, and Google Nest Wifi only supports one unit in bridge mode. On full fibre, the best option is to connect the Nest Wifi straight to the Openreach fibre box (PPPoE, login from Vodafone), as long as you don't need the Vodafone home phone. Otherwise keep the Nest Wifi as the router behind the hub, turn off the hub's Wi-Fi and use its DMZ setting.
Before You Start: Two Questions
- Full fibre or part fibre? On full fibre there's an Openreach fibre box on the wall, and your mesh can connect to it directly. If you're on part-fibre broadband, the Vodafone Hub is also your modem, so it has to stay.
- Do you use the Vodafone home phone? If your home phone plugs into the Vodafone Hub, removing the hub stops the phone working, so keep the hub and use Option 2 below.
Option 1 (Full Fibre, No Home Phone Needed): Nest Wifi Direct
This is the best setup for Google Nest Wifi, because it stays in router mode and every Nest Wifi point keeps working.
- Connect the main Nest Wifi router to the network port on the Openreach fibre box.
- In the Google Home app's advanced networking settings, set the WAN connection to PPPoE and enter the login details. Vodafone uses PPPoE with a username that looks like dsl…@broadband.vodafone.co.uk and a password. Ask Vodafone for them, ideally on live chat so you can copy them exactly: the password is case-sensitive and letters like l and 1 are easy to mix up.
- Restart and check you're online, then unplug the Vodafone Hub.
Option 2 (Keeping the Hub): Nest Wifi as Router, Hub DMZ
Normally you'd use bridge mode, but in bridge mode, Google Nest Wifi and Google Wifi only work as a single unit. Any extra points stop working, which defeats the point of mesh. So instead:
- Connect the main Nest Wifi router to the Vodafone Hub and leave it in router mode.
- Open the hub's settings (the address and admin password are on the hub's sticker or card) and turn off its Wi-Fi.
- Set the hub's DMZ, if it has one, to the Nest Wifi router, to reduce double NAT problems with games and VPNs.
If Vodafone's full fibre at your address runs on the CityFibre network rather than Openreach, the settings differ, so check with Vodafone.
Still Not Right? Quick Checks
- Two Wi-Fi networks? If the Vodafone Hub's Wi-Fi is still on, devices may join it instead of the Nest Wifi. Turn it off, or give it a completely different name.
- Restart in order: the Vodafone Hub first, then the main Nest Wifi unit once the hub is online, then the other units.
- Main unit next to the hub, connected by cable. Other units about halfway to the weak areas, not in them.
- Use cables between units where you can. Wired connections between mesh units give much better speed than wireless.
- Smart plugs and cameras won't connect? Many only use 2.4GHz. See smart device won't connect to Wi-Fi.

Common questions
Yes. Keep the Vodafone Hub as the router and leave the Nest Wifi in router mode with the hub Wi-Fi off, or on full fibre connect the Nest Wifi straight to the Openreach fibre box if you don't need the home phone.
On full fibre, usually yes: connect the Nest Wifi to the Openreach fibre box (PPPoE, login from Vodafone). On part-fibre broadband the hub is also your modem, and if your home phone plugs into the hub it needs to stay.
A PPPoE username, usually starting dsl and ending @broadband.vodafone.co.uk, and a password, both from Vodafone. Ask on live chat so you can copy them exactly.
Yes, if the Vodafone Hub stays connected and the phone plugs into it. If you remove the hub, a home phone that plugs into it stops working.
