Can you have two internet providers in one house?

Yes. Nothing stops a home from buying service from two internet providers at once. Each company installs its own line and modem, and each sends its own bill. The two networks do not talk to each other unless you add a router that can use both, so plan the wiring before you order the second line.

People do this for three reasons:

• A backup for working from home, so a cable outage does not end the workday. A cheaper 5G home internet plan is a common second line, since it does not share the cable or fiber path.
• Separate networks for a home office, a rental unit or a shared house, with separate bills.
• Gaming on fiber for its lower, steadier latency while the rest of the house streams on the other line.^[1]

How to use both lines:

• Simplest: two separate Wi-Fi networks. Devices join one or the other.
• Automatic failover: a router with two WAN ports (often sold as dual-WAN) switches to the second line when the first drops. Wired devices on Ethernet get the steadiest result.^[1]
• Check for installation fees, equipment charges and promo end dates on both plans. Two bills means two sets of each.

To find a second provider, search your address on the FCC National Broadband Map. It lists every company that reports service there, including fiber, cable, DSL, fixed wireless and satellite.^[2] Many homes have one wired choice plus one or two wireless ones.

Start with our ZIP code internet availability checker to see which providers the FCC lists near you, then call to confirm a second line at your address. If the goal is fixing a flaky connection rather than adding one, read internet keeps dropping: switch or fix first.
