How to Reduce Packet Loss in Games
Packet loss is not a single problem. Inside your house it means a Wi-Fi, cable or router fault — free to fix and no network product can help. On your ISP's peak-hour transit, it means congestion into the game datacentre — the specific case a multi-route booster like ExitLag is designed for. Server-side loss is nobody's fault and no fix. Diagnose with a five-minute wired traceroute before you spend anything.

Cause-by-cause diagnostic table
Run a wired traceroute (WinMTR on Windows, mtr on macOS / Linux) to the game server IP for five minutes. Match the pattern of loss to a row below.
| Symptom | Likely cause | How to test | Possible fix |
|---|---|---|---|
| Loss visible in tracert to your first hop (your router) | Wi-Fi retransmissions, bad ethernet cable, dying switch port | Move to a different LAN port; try a known-good cable; ping the router by IP for two minutes and count drops | Replace cable / port; move to a wired connection; reboot the router |
| Loss visible on hops 2–4 (ISP's own backbone) | Faulty ISP equipment or degraded local peering | Repeat the trace at a different time of day; if loss persists at low-traffic hours it is not congestion, it is broken hardware | Call the ISP with the trace attached; a hardware fault is their responsibility |
| Loss on middle hops during peak hours only | Peak-hour congestion on the ISP's transit path to the game datacentre | Repeat the trace at 06:00 vs 20:00; congestion loss disappears overnight | Multi-route booster (ExitLag) or single-route booster (GearUP / LagoFast) — this is the specific case they help |
| Loss only on the final hop (game server) | Either the server discards ICMP (a false positive) or the game's datacentre is genuinely degraded | Check the game's status page; check whether other players in your region report the same | Wait it out — nothing on the client side can fix a server-side incident |
| Loss only when you or a housemate is streaming or uploading | Uplink saturation — your outbound bandwidth is full | Pause the upload / stream for five minutes and repeat the trace | Enable QoS on the router prioritising game traffic; move backups to overnight; upgrade uplink |
Where to spend effort — and where not to
- Step 1
Is the packet loss visible on a wired traceroute at hop 1 or hop 2?
If yes. The problem is inside your house. Replace cable, swap port, reboot router, move off Wi-Fi. No booster or VPN will help.
If no. The problem is external. Continue diagnosis.
- Step 2
Does the loss disappear overnight (06:00) but return at 20:00?
If yes. This is peak-hour transit congestion. This is the specific case a route optimiser is designed to rescue.
If no. The loss is either constant (broken ISP equipment) or isolated to one destination (game datacentre incident).
- Step 3
Do other players in your region report the same problem right now?
If yes. Server-side incident. Check the game's official status page and wait it out.
If no. The problem is on your specific route. Try a booster's free trial on your problem hour.
Try these before you pay for anything
- Move to a wired ethernet connection. Wi-Fi retransmissions read as packet loss to games.
- Replace the ethernet cable — a bad cable is invisible on the surface but drops packets under load.
- Reboot the router. Bufferbloat and NAT-table exhaustion accumulate silently and a reboot clears both.
- Update the router firmware. Modern firmware often includes fixes for driver-level packet drops.
- Pause all background uploads: cloud backup, Twitch, cloud photo sync, patch downloads.
- Enable QoS on the router prioritising game traffic if your household runs a lot of concurrent uploads.
- Force a specific game data-centre through the game's launcher if it offers a picker.
- Baseline everything with a five-minute wired traceroute — this is your evidence when you call the ISP or subscribe to a booster.
The one case where a booster genuinely helps
If your five-minute trace shows loss on middle hops during your play hour but not overnight, this is the specific problem route optimisers exist for.
Multi-route packet duplication is the architecture most useful against transient single-hop loss — the same packet is sent down multiple parallel paths so a drop on any one is recovered from the others.

Common packet-loss questions
- What is packet loss and why is it worse than high ping?
- Packet loss is when data packets never reach the game server (or the server's reply never reaches you). High ping delays action; packet loss makes actions disappear entirely — no shot registered, no movement update, no ability cast. Games extrapolate missing packets, which is why loss produces teleports and phantom hits rather than slowness.
- How much packet loss is acceptable in an online game?
- Zero is the honest answer for competitive play. Anything sustained above 1% will produce visible artefacts. Sub-1% short bursts are usually invisible thanks to netcode interpolation, but the moment loss becomes persistent you will feel it — cancelled channels, missed hitreg, rubber banding.
- Can a VPN or game booster reduce packet loss?
- It depends where the loss originates. If loss is on the transit path between your ISP and the game datacentre, a route optimiser can shift you onto a cleaner path — multi-route architectures duplicate packets across parallel routes so single-hop drops become invisible. If loss is inside your house (Wi-Fi, cable, router), no network product can help.
- How do I test whether packet loss is on my line or the game's route?
- Run a wired traceroute (mtr or WinMTR) to the game server IP for five minutes. The tool shows loss percentage at every hop. Loss at hop 1 or hop 2 is your router or ISP entry. Loss on a middle hop is transit congestion. Loss only at the final hop is often server-side (the game's datacentre discards responses to ICMP but not real game traffic).
- Why does packet loss only happen at night?
- Peak-hour congestion on the shared ISP transit path to the game datacentre. When everyone in your neighbourhood streams and downloads at once, the ISP's uplink oversubscribes and the queue drops packets. This is the case where routing software helps most.
- Does packet loss cause rubber banding?
- Yes — rubber banding is one of the most common visible symptoms of packet loss. When the client sends movement updates that the server never receives, the server keeps you at the last confirmed position and the client eventually snaps you back. See the dedicated rubber banding guide for the full playbook.
