Brawl Stars Ping & Packet Loss Test

Keep getting the red Wi-Fi symbol of death? Mortis dashes not registering? Piper shots firing a second late?

Brawl Stars runs on a highly synchronized, server-authoritative netcode that processes matches at 30Hz. In a fast-paced 3v3 arena where dodging is everything, your phone must exchange ~100-byte UDP packets with Supercell's servers 30 times every second. If your cellular data or home router drops even a single packet, the server halts your brawler, resulting in the dreaded flashing red Wi-Fi icon. Standard internet speed tests completely fail to diagnose this because they only check raw TCP download speed. Mobile MOBAs require an uninterrupted stream of data, not just fast downloads. Our tool simulates this exact 30Hz traffic to expose the micro-stutters ruining your Trophy push.

30 Hz one update every 33.3 ms

What this test sends: 30 packets per second of 40 bytes, matching Brawl Stars rather than a generic ping. estimated

Supercell publishes no tick rate. Every third-party figure we could trace led back to a copy of our own page, so this stays an estimate.

How to Read the Brawl Stars Network Graph

Run the 30Hz test above for at least 60 seconds. Here is what your results mean for Brawl Stars:

Red Lines (Packet Loss)

Red vertical lines mean your connection dropped data entirely. In Brawl Stars, this directly triggers the red Wi-Fi symbol in the middle of your screen. It causes "ignored inputs"—you release the joystick to fire your Super, the yellow ring flashes locally, but nothing happens and you die. The server never received your command.

High Jitter (Stability)

Jitter is ping fluctuation. If your ping rapidly bounces from 30ms to 120ms, you will experience "moonwalking." Enemy brawlers will slide across the screen without their walking animations playing, and your own movement will feel like you are dragging your brawler through thick mud.

High Ping (Latency)

High baseline ping causes severe shot delay. When you aim and release an attack, the projectile takes a fraction of a second to actually leave your brawler. Against highly mobile brawlers like Max or Stu, leading your shots becomes mathematically impossible.

How to Fix Brawl Stars Lag & Red Wi-Fi Icon

If the tool above shows packet loss or high jitter, try these specific fixes.

1. Disable Wi-Fi Assist / Smart Switch

The Symptom: The game runs perfectly, then randomly freezes for 3 seconds with the red Wi-Fi icon, then fast-forwards to you being dead.

Smartphones actively try to swap between Wi-Fi and 4G/5G when the signal fluctuates. During this swap, your phone instantly drops all UDP packets connected to the Supercell server.

Fix Go to your phone settings. On iOS, turn off Wi-Fi Assist. On Android, turn off Switch to mobile data. Force your device to commit to a single connection.

2. Use 5GHz Wi-Fi or an Ethernet Adapter

The Symptom: Constant micro-stutters and shot delay while using Bluetooth earbuds.

The standard 2.4GHz Wi-Fi band uses the exact same radio frequency as Bluetooth devices. Connecting wireless earbuds while playing on 2.4GHz Wi-Fi causes massive packet collision and latency spikes.

Fix Connect to your router's 5GHz Wi-Fi band. For the absolute best competitive connection, use a USB-C to Ethernet adapter to hardwire your phone directly to your router.

3. Fix the 78% / 92% Loading Screen Bug

The Symptom: The game gets stuck at exactly 78% or 92% on the loading screen and refuses to put you in the match.

These specific percentages are where the Brawl Stars client attempts to establish the final UDP handshake with the live battle server. If your router's firewall blocks it, or your packet loss is too high, the handshake fails.

Fix Toggle airplane mode on and off to reset your network cache. If playing on a school or work Wi-Fi network, they likely have UDP ports blocked—you must switch to cellular data.

4. ISP Routing to Supercell Servers

The Symptom: You have the red Wi-Fi icon constantly, even though you have full bars of 5G or fast home fiber.

Supercell hosts regional servers using Amazon Web Services (AWS). Sometimes your mobile provider or ISP takes a terrible, highly congested routing path to get to these specific datacenters.

Action Use our server map above to test routing. If your route is broken, use a mobile gaming VPN (like GearUP Booster) to force your traffic down a cleaner, more direct backbone to the Brawl Stars servers.

Frequently Asked Questions

What does the flashing red Wi-Fi symbol mean in Brawl Stars?

The red Wi-Fi icon is Supercell's universal warning for severe packet loss or a ping spike exceeding 200ms. It means your device has temporarily stopped sending or receiving data from the battle server. To the server, your brawler is just standing completely still.

Why is there a delay when I shoot in Brawl Stars?

Shot delay is caused by high ping. When you release the attack joystick, your phone sends a command to the server. The server registers the attack, then sends a packet back to your screen telling the animation to play. If your ping is 100ms+, that entire process takes a noticeable fraction of a second.

Why did my Super or Gadget not activate?

This is caused by packet loss. You tapped the Gadget button, and your local client initiated the visual ring effect on your screen, but the UDP data packet was dropped by your internet provider before it reached the 30Hz server. The server rejects the cast because it never received the command.

Why does Brawl Stars lag with good internet?

Fast internet (bandwidth) is completely different from stable internet (jitter/packet loss). Brawl Stars uses tiny amounts of data, so having gigabit download speeds doesn't matter. If your router drops packets due to a crowded Wi-Fi channel, you will lag and get the red Wi-Fi icon. Switch to a 5GHz Wi-Fi band.
