[EASY] Connect UniFi USG to Google Fiber directly using only the UI

[ Edited ]

While there are other, older threads about this, I wanted to start a new one showing UniFi 5.10's new interface on how to connect your USG's WAN to Google Fiber directly without Google's router in the way. This method only uses the UniFi UI.

 

To do so, you need to:

 

  1. Set the VLAN ID to 2
  2. Turn on QoS of 3 (previously had to do this in the config files via SSH)
  3. Make sure your Fiber wall jack has power.

That's it. I was able to do this in minutes.

 

Here's my config which includes Cloudflare's super fast DNS servers:

Previously, you'd have to SSH in and set the QoS value that way; referred to as `egress-qos 0:3` in the config file, but now, this is available in the UI. You also weren't able to get IPv6 working either, but now, it's as simple as making sure your prefix delegation size is 56.

 

Since neither the USG3 or USG4 has PoE, you will need to power the Google Fiber wall jack yourself. I used a PoE injector that came with a UniFi AP, but you can connect any microUSB power adapter to the fiber box itself too. In fact, Google even provided one in the box with the router.

As soon as my fiber modem turned on, I had an IP.

How long did it take for your usg to obtain a WAN IP ?

Re: [EASY] Connect UniFi USG to Google Fiber directly using only the UI

Hi,

i am trying to get these settings to work but not getting anywhere and don’t understand why.

 

i have google fiber 100/100 connection set up. If I use their network+ box I get internet.

 

disconnected the network+ box, and connected the fiberjack to WAN on my USG 3P

 

created a network called WAN

Purpose: WAN

network group: WAN

port: WAN 1

IPV4: Using DHCP 

IPV6: Using DHCPv6

prefix delegation size: 56

DNS server: 1.1.1.1

use VLAN ID: checked, 2

QoS tag: 3

smart queues: disabled 

 

still no internet after provisioning 

tried rebooting USG: no change 

 

any ideas?

Is your Google Fiber wall jack powered? It either powers over USB or PoE, but the UniFi USG does not have PoE.

Yep its powered.

I have no idea what happened but after about 20 min, it suddenly just started working.

I saw other posts of people saying they left it over night and suddenly it worked.

I can only assume there is some sort of a process or batch pass that runs on Google's side that allows it to run but I dont know nearly enough about networking to even begin to say what it would be
