Google Nest Wifi With Plusnet: 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 Plusnet broadband? The right setup for this combination, whether to keep the Plusnet Hub Two, what full fibre needs, and how to protect your home phone.
Quick fix
On full fibre the Plusnet Hub Two can't act as a modem, 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, your Plusnet account login), as long as you don't need the Plusnet 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 Plusnet 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 Plusnet Hub Two'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: On full fibre the Plusnet Hub Two can't act as a modem, 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, your Plusnet account login), as long as you don't need the Plusnet 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. On part-fibre broadband, the Hub Two is also your modem. You can either keep it as the router, or set it up as a modem only and let the mesh log in with your Plusnet details.
- Do you use the Plusnet home phone? If your home phone plugs into the Plusnet Hub Two, 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. Plusnet uses PPPoE with your Plusnet account username, in the form username@plusdsl.net, and your account password (not the Wi-Fi password). On full fibre, leave any VLAN setting blank or set it to 0, not 101.
- Restart and check you're online, then unplug the Plusnet Hub Two.
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 Plusnet Hub Two 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.
On part-fibre broadband, the Plusnet Hub Two can act as a modem, so your mesh can log in with your Plusnet details. That isn't needed on full fibre.
Still Not Right? Quick Checks
- Two Wi-Fi networks? If the Plusnet Hub Two'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 Plusnet Hub Two 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 Plusnet Hub Two 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, your Plusnet account login). On part-fibre broadband the hub is also your modem, and if your home phone plugs into the hub it needs to stay.
PPPoE with your Plusnet account username (username@plusdsl.net) and account password, with VLAN blank or 0 on full fibre.
Yes, if the Plusnet Hub Two stays connected and the phone plugs into it. If you remove the hub, a home phone that plugs into it stops working.
