Get a load balancing router. Hook the router up to at least two independent internet providers. I bought this one "TP-Link TL-R470T+ Load Balance Broadband Wired Router" on eBay for $21 (was brand new in the box too). I have it hooked up to my DSL right now and I'm going to get a LTE router (that uses Verizon) and run a cable to the TL-R470T+ so it will be able to use the LTE if my internet goes down -- which has frequent outages...
