Why is Fortnite lagging?

The short answer

Fortnite needs a quick, steady connection, not a fast one. Lag, delayed builds and rubber-banding usually come from Wi-Fi interference, your connection slowing down when others use it (bufferbloat), or playing on a server region far from you. Turn on Fortnite's network stats to see your ping and packet loss, then fix whichever one is the problem.

Network lag or low frame rate?

Two different problems both get called "lag":

Network lag: builds appear late, shots don't register, players teleport, you get pulled back (rubber-banding). The game itself still looks smooth.
Low frame rate: the whole picture stutters or looks choppy. That's your device's performance, not your Internet. Lowering graphics settings helps with this one.

This guide is about network lag.

See your ping and packet loss in Fortnite

Fortnite's settings include an option to show network debug stats (often labelled "Net Debug Stats") on screen, including your ping and packet loss. The exact menu has moved between seasons; look in the game UI or HUD settings. Watch them during a match:

Ping under about 50 ms feels responsive; over 100 ms you'll notice delay.
Packet loss should be 0%. Any regular loss causes rubber-banding and missed actions.

The usual causes

Wrong server region

Fortnite usually picks your matchmaking region automatically, but if it's set to a region far away, every action travels further. Check the matchmaking region in the game settings and pick the one closest to you.

Wi-Fi

Consoles and PCs on Wi-Fi often lose small bursts of packets, especially far from the router. That shows up as packet loss in the debug stats and as rubber-banding in game.

Bufferbloat

If Fortnite lags when someone else at home streams, downloads or uploads, and is fine when they stop, your connection has bufferbloat. See what is bufferbloat.

Background downloads

Game and system updates downloading on the same console or PC can cause sudden spikes.

How to fix it

Run our test with the speed test included, to see whether the problem is Wi-Fi-style loss, bufferbloat or high base ping.
Use an Ethernet cable for your console or PC. It's the single most reliable fix for packet loss.
Set the closest matchmaking region.
Turn on Smart Queue Management (SQM) in your router if lag comes and goes with others' use. See how to fix bufferbloat.
Pause downloads on the gaming device and others while you play.
Restart your router if lag suddenly appears and nothing else has changed.

Questions people ask

What's a good ping for Fortnite?

Under 50 ms is good, under 30 ms is great. A steady ping matters more than a low one: jumping between 20 and 120 ms feels worse than a steady 60.

Why do my builds go through late?

Building is very sensitive to delay and packet loss: each build has to be confirmed by the server. High ping, jitter or packet loss all make builds feel late. Check the debug stats while building.

Does a faster Internet plan help Fortnite?

Rarely. Fortnite uses very little bandwidth while playing. Fixing Wi-Fi, bufferbloat or the server region helps much more.
