Question

What do I need to connect between my router and a hotspot to provide automatic internet backup should my home internet go down?  

Answer 1

You need a dual want router. Then you could have 2 internet services. 1 for back up.  

Answer 2

Cell spot

Answer 3

What @debroahdebs978 said. I’ve got a Ubiquiti USG-PRO-4 up at my mountain house, it has 2 WAN ports. One is connected to a cable modem, the other to a Netgear LTE modem with a pay-as-you-go SIM in it. This is just a router - if you have some all-in-1 cable modem + router + wifi access point now, you’ll need the other “pieces” of that equation.  

Answer 4

You could do it with some creative routing without a dual wan firewall.  

Answer 5

Dual router, 2 WAN ports and a GSM modem with service is what we use. Its the failover, so you dont use up bandwidth or minutes unless needed.  

Answer 6

Ubiquiti Edge Router X, you’re mobile hotspot and a Raspberry Pi. Set the Pi up to bridge wireless from your hotspot to LAN. That will be your WAN2 and your main internet WAN1. Then configure the edge router. There’s YouTube videos on how to do it

Answer 7

Pep link sells routers for this

Answer 8

Phat stacks

Answer 9

With a Ubiquiti EdgeRouter you can use VRRP to watch connections and if one goes down, it will fail over. You can also make it switch back to the primary when it sees the connection come back up.  

Comments

The router itself can do all this without adding extra equipment, especially if the hotspot has an Ethernet port.
