USG 3-P Failover 2 Cellular Hotsptot: HOW TO.
Description

With the new beta WAN2 feature of the 'USG 3P' one can turn the VOIP port into a failover or load balance connection.  This guide shows one way of doing this leveraging your smartphones hotspot feature.

 

Overview

  • Setup  TL-WR810 mini router with cell phone hotspot
  • Configure USG WAN2 Port
  • Plug WAN2 port of USG into mini router
  • Be patient
  • Test failover

Setup Router

I used the TPLink WR810 though i am confident this will work with any router that supports operating in client mode including the routers lower in this travel range https://www.amazon.com/gp/product/B01CVOLGOG/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1

  • Boot the router, when it is booted you should be able to join a wirelss device to it to configure it.  Here is the sequence from my ipad.  Be sure to make sure you use the auto wizard, and remeber to set it to smart IP and use the site survey tool to find your hotspot

  • Enable the hot spot on your phone (this assume you have that enabled by your carrier and you are ok with using your cell phone data!)

  • Start the quick setup wizard, follow this sequence exactly and use trhe site survey to find your phone - if the site survey doesn't see the phone click refresh and double check your cell phone settings.

Be patient on the reboot and if you did everything right you will the following.  If you didn't then you will need to reset the router and start again!

Setup the USG 

First you need to enable the WAN2 setting here:

Once the USG has reprovisioned open up the device and set the port to failover or loadbalance.  In this example we will do failover as this is for emergencies and my phone is not reliable enough for loadbalance.

Initially Wan2 may not appear - have patience grasshopper.

I am not an expert and don't play one on TV.
Don't forget RTFM https://www.ubnt.com/downloads/guides/UniFi/UniFi_Controller_V5_UG.pdf it really is impressive documentation.

Seems there is a post size limit - here is the rest:

 

It will appear eventually like this

you may see the IP address change and fluctuate - this lets the router adjust to different IPs the phone may give the router operating in client mode.

 

Now pull the cable out of WAN1 and see what happens!  After a couple of minutes it will failover to just WAN2 - don't worry that WAN2 never shows as green.  Thats a known issue in this build:

have fun, i hope this was useful to someone, i will do more if folks like them!

Point of clarification.

 

1) This solution doesn't solve double NAT problem - the cell phone has a NAT in it

2) This is great for emergency use, especially in my home sceanrio where i want something i can quickly turn on when comacast goes down, i wouldn't advocate it as a robust solution one could roll out at ones customers.

an airGateway would be a cheap alternative for the TL-WR810. and shoukd be avaluable to anyone reading this...

AirGateway hasn't got a USB port for a modem.

this guide is not using a usb. it's using wifi tethering. his other guide uses usb. you are correct the airGateway would not work on his other guide just this one.

Hey everyone.

Spent the last day or so ( here and there ) working on setting this failover option up with my TP- TL-WR710N using latest firmware. After following the instructions to the T, nothing would work after I pulled the wan1 port for failover. So some googling later and found this to be very helpful and fixed my issue: 


The TL-WR702N has a configuration option called 'WDS mode', changing this from Auto to 3 Addr solved all my problems.Hopefully this solution helps some of you to.

Any updates to this, looks to be exactly what I'm looking for.

I'm looking for a backup for worst case (very rare conditions).

 

Our kettle (transformer) out on the street took a lightening strike the other day and had to be replaced.  The only item damaged was my cable modem everything else powered up just fine; everything is on an UPS (including the modem), the only thing not protected is the Coax (the shield is ground).  My guess is it arced through to core and took out the modem.  We were down for the night and part of next day until I got a modem that worked .  Fortunately I'm 20 mins away from my provider and the phone techs were good guys - set their all in one gateway to bridged mode and turned off all the features - router/wifi/etc).  The good part was they up'ed my speed and lowered my cost by $2 a month.
