Fixing packet loss in Warzone is the quickest way to stop the rubber-banding, teleporting enemies and missed shots that ruin a match. Packet loss happens when data travelling between your console or PC and the game server fails to arrive, so the game has to guess what is going on. The good news is that most cases come from your own home network and can be fixed in a few minutes. This guide walks through every reliable step, in order, for Call of Duty: Warzone on PC, PlayStation and Xbox.
What you will need
Before you start, it helps to have a few things on hand: an Ethernet cable long enough to reach your router, access to your modem and router (and their power plugs), and your game launcher open (Battle.net or Steam on PC, or the console store). You do not need any special software. Work through the steps in order and re-check the in-game readout after each one so you can see what actually helped.
How to fix packet loss in Warzone
-
Step 1: Confirm packet loss with the network overlay
Turn on Warzone's network telemetry so you can measure the problem instead of guessing. Open Settings > Interface and enable the on-screen Telemetry / network information so it displays Packet Loss and Latency. While playing, watch the packet-loss figure: anything sustained above roughly 1–2% is enough to cause rubber-banding and hit-registration issues. Separating packet loss from high ping or low frame rate tells you exactly which fix to apply.
The in-game readout shows packet loss alongside ping and FPS so you can pinpoint the issue. -
Step 2: Switch from Wi-Fi to a wired connection
Wireless interference and jitter are the single biggest cause of packet loss for most players. Plug your gaming PC or console directly into the router with an Ethernet cable. A wired link removes the dropouts caused by walls, neighbours' networks and microwave interference, and it almost always delivers a steadier connection than even strong Wi-Fi. If running a cable is impossible, move as close to the router as you can and use the 5 GHz band.
A LAN cable bypasses the wireless interference that drops packets. -
Step 3: Power-cycle your modem and router
Networking hardware that has been running for weeks can build up errors that show as intermittent packet loss. Unplug both your modem and router for about 30 seconds. Power the modem on first and wait until its lights settle and it has fully synced, then switch the router back on. While you are there, reseat the coax, DSL and Ethernet cables at both ends — a loose or damaged cable causes random drops that are easy to overlook.
Restart the modem first, let it sync, then restart the router. -
Step 4: Free up bandwidth and close background apps
If your connection is saturated, Warzone's packets have to fight for space and some get dropped. Pause anything that is hogging the line: 4K streaming, large game or OS downloads, and cloud backups or file sync. Ask anyone else in the house to hold off on heavy streaming while you play. If your router supports QoS or device prioritisation, set your gaming machine as the priority device so its traffic is handled first.
Stop bandwidth hogs and prioritise your game device to keep the line clear. -
Step 5: Update, scan & repair, then check with your ISP
Corrupt game files and out-of-date drivers can mimic network problems. In Battle.net open the options and run Scan and Repair (or use Verify Integrity of Game Files on Steam), and make sure Warzone and your GPU and network drivers are up to date. If packet loss continues after all of the above, test on a second device and a different network to prove it is the line, then contact your ISP and ask them to check for faults — the problem may be outside your home entirely.
Repair files, update drivers, and rule out your ISP if the loss persists.
Extra tips to keep packet loss away
- Use a quality cable. A worn or very long Ethernet cable can introduce errors; a fresh Cat 5e or Cat 6 cable is cheap insurance.
- Avoid powerline adapters where possible. They are better than Wi-Fi for some homes but can drop packets on noisy electrical circuits.
- Pick the right data centre/region. Connecting to a server far away increases the chance of loss along the route; play on servers near you.
- Restart the game and your device after making network changes so Warzone re-establishes a clean session.
Troubleshooting
Packet loss only spikes during fights
Short bursts during heavy combat are often the server or route under load rather than your hardware. Try a different data centre and play at off-peak times to see if it improves.
The wired connection still drops packets
Swap the Ethernet cable and try a different port on the router. If loss continues on a wired link, the fault is most likely your modem, the line, or your ISP — move to Step 5.
Everything tests fine but Warzone still rubber-bands
Run a Scan and Repair and reinstall the latest update. If a single Warzone session is bad but your speed test is clean, the issue may be a temporary server problem on Activision's side.
Frequently asked questions
What causes packet loss in Warzone?
Most packet loss comes from an unstable home connection — Wi-Fi interference, a saturated line, a faulty cable or aging router hardware. It can also be caused by your ISP's network or, occasionally, by overloaded game servers.
How much packet loss is too much in Warzone?
Anything consistently above about 1–2% will start to cause noticeable rubber-banding and hit-registration problems. Ideally you want packet loss at 0% with only the occasional brief spike.
Does a wired connection really reduce packet loss?
Yes. For the large majority of players, switching from Wi-Fi to Ethernet is the most effective single fix because it removes wireless interference and jitter that cause dropped packets.
Is Warzone packet loss my fault or the server's?
Test on another device and network. If the loss follows you everywhere, it is your line or ISP; if only Warzone is affected while everything else is fine, it is more likely a game-side or server issue.
Final thoughts
Packet loss feels like the game is working against you, but it is usually fixable at home. Measure it with the in-game overlay, get on a wired connection, restart your modem and router, clear out bandwidth hogs, and repair the game before you blame anything else. If it still persists after all that, the trail leads to your ISP. For official status and support, you can always check the official Call of Duty: Warzone website.
