Fortnite is one of the most popular battle royale games. It was released shortly after PUBG but has gathered a broader fanbase, mostly because it’s free to play.

Additionally, Fortnite has a lower PEGI rating (12) than PUBG (16+). This automatically translates into a wider range of players, given the age difference.

You can play solo, in teams of two, or as a 4-player team, depending on your preferences. The point of the game is to be the last player/team standing.

In the beginning, you must parachute yourself out of a flying vehicle (bus). Then you loot ammo, armor, and whatnot, and start hunting your enemies. There’s a total of 100 players in each session, so competition is fierce.

That’s why what we’re about to say will make perfect sense to you. If you lag even for a split-second in Fortnite, your character will probably die. But the lag isn’t the only issue here. There’s also packet loss, jitter, and even connection timeouts.

Packet loss is a real struggle with pros and amateurs alike and it usually makes the difference between winning a game (or getting as close as you can to being the last player/team standing) or losing it miserably.

What is upload packet loss?

In Fortnite, packet loss is no different than in other games/services. Data packets that were set on a course never make it to their destination. This means that data gets lost and as a result, you lag, rubberband, or disconnect from the server altogether.

If your connection times out, that’s it. You’re out of the game and you already lost. However, most packet loss situations are less severe, and let you recover quite fast.

There are two types of packet loss: outbound and inbound. Let’s make this as clear as possible:

  • Outbound (upload) packet loss – data flowing from your PC toward the Fortnite server
  • Inbound (download) packet loss – traffic that flows toward your PC from the game server

Therefore, upload packet loss means that the server sends you some data packets that never make it all the way to you. As a result, you might experience the symptoms described above.

What causes packet loss Fortnite?

A lot of things can trigger packet loss, even in Fortnite. Usually, it’s the game server’s fault, in which case the situation fixes itself. However, sometimes you or your ISP might be the cause.

To paint a clear picture, even your Ethernet cable can cause packet loss. Want more? Fine. Even choosing Wi-Fi over a wired connection can lead to packet loss. As you can see, there are a lot of things that can cause packet loss in Fortnite.

But realistically speaking, most of the time packet loss occurs as a result of network congestion.

How to fix packet loss Fortnite?

1. Use a VPN

Private Internet Access

  1. Download Private Internet Access
  2. Install PIA on your PC
  3. Launch it and log into it
  4. Connect to your favorite server
  5. Launch Fortnite and see if the packet loss issue persists

Private Internet Access is a Kape Technologies owned VPN service that passed our tests with flying colors. It’s a well-balanced, feature-rich VPN that can help you get rid of several issues.

For instance, you can use it to secure your connection, keep your traffic data private, and even unblock geo-restricted content.

It’s worth mentioning that if the packet loss issue is server-side or occurs on your home network, using a VPN won’t work. The packets must leak on your ISP’s side for VPNs such as PIA to be of any help.

  3. Take the necessary measures to fix packet loss as explained below

Depending on your test results, you will (or won’t, hopefully) experience packet loss in one of these four locations:

  • Your home network (including your PC, router, home line, and even Ethernet cables)
  • ISP’s network and its servers
  • The servers of the network distribution company (the one above your ISP)
  • Fortnite game servers

After determining where the problem is located, here’s what you can do to alleviate the packet leak issue:

  • Check/repair/update/upgrade/replace components in your home network (PC, router, cables)
  • Contact your ISP to fix the issue (if it’s their fault)
  • Ask your ISP to contact the network distribution company
  • Contact Fortnite’s support team if the problem’s on their side

Fortnite packet loss can often be fixed

If you’re having packet loss issues in Fortnite, don’t fret. It usually passes by itself without your assistance. However, if you notice a pattern in these leaks’ occurrence, you might want to step in.

Note that using a VPN won’t solve packet loss issues every time. This method’s efficiency depends on the location of the leak inside your connection.

However, it’s good having a VPN on your PC, as it can keep a lot of things at bay, such as prying eyes, or even hackers.
