How to use two internet connections at the same time to play

Did you know you can use two internet connections on your PC at the same time? And that it can protect your gaming session from drops?

The technique is called failover: if your primary connection fails, traffic automatically switches to the backup. The game doesn’t notice, you don’t DC.

What internet failover is

Think of failover as an automatic backup. Just like you back up files so you don’t lose data, failover is a backup of your connection so you don’t lose your game session.

PingArmor monitors both connections in real time. If the primary drops or gets slow, it switches to the other one in about 2 seconds — without disconnecting you from the game.

Second internet options

You don’t need to pay for two ISPs. Your second connection can be:

Phone via USB tethering (most common)

The simplest and cheapest option. Most players already have one:

1. Plug the phone into your PC with a USB cable
2. Enable “USB tethering” in your phone settings
3. Windows picks it up as a new network interface

4G/5G from your phone is more than enough as a backup. It doesn’t need to be fast — it just needs to work when the primary drops.

Other options

• Ethernet from another ISP — if you have fiber from two different providers
• Wi-Fi from another router — a neighbor’s router, a repeater, or a second network
• USB 4G/5G modem — a dongle plugged straight into the PC

Do I need a special router?

No. PingArmor does everything in software, straight on Windows. It builds an encrypted WireGuard tunnel between your PC and a relay server, and handles switching between connections automatically.

You don’t need:

• A dual-WAN router
• Advanced network config
• Technical know-how

How the switch happens

PingArmor monitors the primary connection in two ways:

1. Gateway ping — checks if the internet is responding (every 750ms)
2. Game latency — tracks real ping to the game servers

If it sees 3 gateway failures in a row, or latency above the threshold on the game servers, it switches automatically. The full process takes about 2 seconds.

When the primary connection comes back and stabilizes, PingArmor does the reverse (failback) and returns to it.

How to get started

1. Create a free account — 3-day trial, no credit card
2. Download PingArmor for Windows
3. Plug in both internets (e.g., ethernet + USB phone)
4. Open the app, log in, click Connect
5. Play normally — PingArmor handles the rest
