My home AT&T fiber goes down on rare occasion. Overall the reliability is pretty high but I wanted to have a failover just in case. This is my home Internet connection – it runs some services, but nothing crucial. I didn’t want to spend a lot of money on this. I have a password for Xfinity WiFi and my neighbors have an Xfinity hotspot so I decided I wanted to use this.

Travel Router Setup
The GL.iNET travel router is somewhat cheap, so if you use one, adjust expectations accordingly, but it’s extremely configurable. It uses a whiltlabeled version of OpenWRT, with some nice defaults. One easy-to-setup option taking a WiFi connection and providing it via the device’s LAN port, called “Repeater”.
I chose the “Scan” option under “Repeater” and selected “xfinitywifi” as my upstream connection. I then connected my laptop to the LAN port, hit Xfinity’s captive portal, and logged in.
Once this was done, I connected the LAN port from the travel router to the WAN2/VoIP port on my Security Gateway.
Once this was connected, I went to my controller, opened the configuration for my Security Gateway, went to the Ports menu and enabled the WAN2 port.
Then, I went to the Site settings for my home and created a new network called WAN2. I set the “Load Balancing” type to “Failover only” as I want to use my fiber line if it’s available.
I saved my setting and that’s it! Ubiquiti makes it easy.
Ubiquti has a pretty good notification system. In the Site settings, I enabled email alerts. (You can configure your email credential settings in your Settings > Controller menu.)
As my Internet seamless failed over I was no longer made immediately aware if my Internet went down. Now I get an email alert when my AT&T fiber goes down.
