Two internet connections, one router

For anyone working from home, a dropped connection means a dropped call. A dual-WAN router watches the main line and switches to a backup automatically, often within seconds.

Compare how the second WAN connects (a spare Ethernet port, USB tethering or a dedicated port), and whether the router supports failover, load balancing or both.

See also routers with USB ports for phone tethering.

Frequently asked questions

What does dual-WAN do?

It lets a router use two internet connections. With failover, the backup takes over when the main line drops. With load balancing, both share the traffic.

Can a phone or hotspot be the backup?

On many routers here, yes: USB tethering or a second Ethernet WAN connected to a 5G hotspot or home internet box.

Does dual-WAN double my speed?

Not for a single download. Load balancing spreads many connections across both lines, so a busy household sees more total capacity.
