What Is Packet Loss? How to Check,
Fix & Stop It for Good
Lagging video calls, rubber-banding in games, buffering streams — if your internet feels broken even though your speed test looks fine, packet loss is likely the culprit. Here's everything you need to know: what packet loss means, what causes it, how to check it online right now, and how to fix it fast.
Your internet speed might look great on paper — but if data packets are getting lost in transit, your connection will feel terrible. Packet loss is one of the most misunderstood and underdiagnosed internet problems affecting millions of American households. This guide explains exactly what it is, what causes it, and how to get rid of it — and when it signals that it's time to find a better internet provider at your address.
What Is Packet Loss?
"Packet loss is what happens when one or more packets of data traveling across a network fail to reach their destination. Instead of flowing smoothly, data disappears in transit — causing lag, freezing, and connection errors."
To understand what packet loss means, think about how the internet actually works. Every piece of data you send or receive — a message, a video frame, a game update, a webpage — is broken into small chunks called packets. These packets travel from your device through your router, your ISP's network, and across the internet to their destination, where they're reassembled.
In a perfect world, every packet arrives intact and on time. But in the real world, networks are imperfect. Cables degrade, routers get congested, and signals weaken. When that happens, packets don't make it through — they're lost. That's packet loss.
So what is a packet loss rate exactly? It's expressed as a percentage: the share of packets sent that never arrived. A 0% packet loss rate means your connection is clean. Even a 1–2% rate can cause noticeable problems for gaming, video calls, and streaming. Anything above 5% is considered severe. You can check your packet loss online right now using our free tool — no download needed.
What Does Each Packet Loss Percentage Mean?
Not all packet loss is equal. Here's a breakdown of what different packet loss rates mean for your internet experience:
| Packet Loss Rate | Status | What It Means for You |
|---|---|---|
| 0% | Perfect | All packets arriving. No issues — this is what you want. |
| 0.1 – 0.5% | Excellent | Barely perceptible. Most users won't notice anything wrong. |
| 1 – 2% | Acceptable | Slight lag in games. Occasional micro-freezes on video calls. |
| 2 – 5% | Poor | Noticeable game lag, choppy calls, streaming buffering. Investigate. |
| 5 – 10% | Bad | Gaming nearly unplayable. Video calls frequently cut out. |
| 10 – 25% | Severe | Most online activities fail. Pages won't load reliably. |
| 25%+ | Critical | Internet is effectively down. Immediate troubleshooting needed. |
How Do You Know If You Have Packet Loss?
Speed tests won't catch packet loss — they only measure bandwidth. Many people wonder "why am I getting packet loss?" without realizing they have it, because their speed test looks fine. The symptoms are the real tell:
- 🎮Games lag or rubber-band — Your character teleports backward. Actions register late. You get kicked from matches. This is the most common complaint from gamers.
- 📹Video calls freeze or pixelate — Zoom, Teams, or FaceTime calls stutter, freeze mid-sentence, or drop audio.
- 📺Streaming buffers unexpectedly — Netflix or YouTube pauses to buffer even though your speeds seem fine.
- 🌐Web pages partially load — Images don't appear, pages time out, or forms fail to submit.
- 💬Messages arrive out of order — Especially noticeable in voice chat apps like Discord.
- 📁Downloads stall or fail — Large file downloads fail mid-way even with good speeds.
What Causes Packet Loss?
Understanding what causes packet loss is the first step to fixing it. There are several culprits — some are in your home, some are your ISP's problem, and some are unavoidable on the wider internet.
In Your Home
- 01Faulty or degraded cables — Old Ethernet cables, loose connectors, or damaged coaxial cables are the #1 cause of home packet loss. A frayed cable can drop 20–30% of packets.
- 02Overloaded router or modem — Consumer-grade routers can only handle so many simultaneous connections. When overwhelmed, they start dropping packets.
- 03Wi-Fi interference — Wireless connections are inherently less reliable than wired ones. Walls, neighboring networks, microwaves, and Bluetooth devices all interfere with your Wi-Fi signal.
- 04Outdated network hardware — A router that's 5+ years old may not handle modern internet speeds efficiently, causing it to drop packets under load.
- 05Driver or software issues — Outdated network adapter drivers on your PC or laptop can cause software-level packet loss even when your hardware is fine.
From Your ISP
- 06Network congestion — During peak hours (6–11 PM), ISPs often route more traffic than their infrastructure can handle, causing packets to be dropped at their end. This is one of the hidden limitations providers don't tell you about during sign-up.
- 07ISP throttling — Some providers intentionally slow certain types of traffic (gaming, streaming, VoIP), which can manifest as packet loss. Learn more about the real cost of internet throttling in 2026.
- 08Aging infrastructure — Older DSL or cable infrastructure in your area degrades over time and is a frequent source of persistent packet loss that only your ISP can fix.
- 09Distance from network node — The farther you are from your ISP's nearest equipment, the higher your risk of packet loss — especially on DSL connections. Fiber internet is not affected by node distance.
On the Wider Internet
- 10Routing issues — Data travels through many servers and routers between you and its destination. Congestion or faults at any point cause packet loss you can't control.
- 11Server-side problems — Sometimes the game or app server itself is experiencing issues, dropping packets at the destination end.
How to Check Packet Loss Online
The easiest way to check packet loss is to use an online tool specifically designed for it — regular speed tests don't measure packet loss. Here's how to check packet loss right now:
Visit our Network Packet Loss Test tool. It sends a series of packets to a test server and measures what percentage fail to return — giving you an instant, accurate packet loss reading.
Run the test at different times of day — especially during peak hours (evenings). A single result may not tell the whole story. Intermittent packet loss is common and only shows up under load.
First test over Wi-Fi, then plug directly into your router with an Ethernet cable and test again. If the wired result is 0% but Wi-Fi shows loss, your wireless setup is the culprit — not your ISP.
If wired-to-router still shows packet loss, bypass the router entirely and connect directly to your modem. If loss disappears, your router is the problem. If it persists, the issue is upstream with your ISP.
On Windows, open Command Prompt and type: ping -n 100 google.com — this sends 100 pings and shows how many were lost. On Mac/Linux use: ping -c 100 google.com
Use ShopLikeSam's free Network Packet Loss Test to check your connection in seconds. No download required — just visit the page and run the test.

How to Fix Packet Loss: 10 Proven Steps
Ready to get rid of packet loss? Work through these fixes in order — starting with the simplest and most common causes first. Most people resolve the issue within the first four steps.
-
Restart your modem and router
Unplug both devices from power, wait 60 seconds, plug the modem in first, wait 30 seconds, then plug in the router. This clears temporary memory issues and re-establishes a clean connection — fixes intermittent packet loss about 30% of the time. -
Switch from Wi-Fi to a wired Ethernet connection
A direct Ethernet cable eliminates wireless interference entirely. This is the single biggest upgrade you can make for gaming, video calls, and streaming stability. -
Replace old or damaged cables
Inspect every Ethernet cable, coaxial cable, and phone line connected to your modem. A Cat5e or Cat6 cable costs under $10 and can completely eliminate packet loss caused by degraded wiring. -
Update your router firmware and network drivers
Log into your router's admin panel and check for firmware updates. Also update your PC or laptop's network adapter drivers via Device Manager (Windows) or System Preferences (Mac). -
Change your Wi-Fi channel or frequency band
If you're on Wi-Fi, switch from 2.4 GHz to 5 GHz for less interference and faster speeds. Also try changing your Wi-Fi channel in your router settings to avoid congestion from neighboring networks. -
Reduce network congestion on your home network
Limit simultaneous heavy usage (streaming, large downloads) while gaming or on video calls. Enable Quality of Service (QoS) in your router settings to prioritize gaming or VoIP traffic. -
Use a VPN (for ISP throttling)
If your ISP is throttling specific types of traffic, a VPN can mask your traffic type and reduce packet loss. This is particularly effective if loss only occurs on gaming servers or streaming services. Check our Bufferbloat Test to see if throttling is also causing latency issues. -
Move your router to a better position
Place your router in a central, elevated location away from walls, metal objects, and other electronics. The closer your device is to the router, the lower your wireless packet loss will be. -
Contact your ISP
If packet loss persists after trying everything above, the problem is likely with your ISP's infrastructure. Call and report the issue — provide your packet loss test results as evidence. Request a line inspection or technician visit. -
Switch to a better ISP
If your provider can't resolve ongoing packet loss — especially if it's caused by aging infrastructure or chronic congestion — it may be time to switch. Fiber internet delivers near-zero packet loss compared to cable or DSL. Use ShopLikeSam to compare providers available at your address.
Packet Loss in Gaming: Valorant, BF6 & More
Gamers feel packet loss more acutely than any other type of user. Even 1% packet loss can cause rubber-banding, missed shots, and disconnect errors that ruin competitive matches. Here's what to do for the most commonly affected games.
What Is Packet Loss in Gaming?
In gaming, your device constantly sends and receives tiny packets of data to the game server — your position, inputs, actions — dozens of times per second. When packets are lost, the server doesn't get your input in time. The result is rubber-banding (your character snapping back), hit registration failures, ability delays, and desync. Use our Ping Test for Gamers alongside the packet loss test — high ping and packet loss often occur together and compound each other's damage.
- Switch to a wired Ethernet connection
- In Settings → General, enable "Show Network Problems"
- Select the nearest server region manually
- Close background apps consuming bandwidth
- Disable Riot Vanguard and reinstall if loss persists
- Try a VPN if specific Valorant servers are affected
- BF6's large-scale battles are highly packet-intensive
- Peak-hour server congestion is the most common cause
- Switch to wired connection first
- Change server region in multiplayer settings
- Update your EA App and game client
- Report persistent issues to EA's server status page
General Gaming Fixes That Work Across All Games
- 🔌Always use Ethernet — This alone eliminates wireless-related packet loss. For competitive gaming, Wi-Fi is never recommended. If you use fixed wireless internet, a wired connection to your receiver is especially important.
- ⚙️Enable QoS on your router — Prioritize gaming traffic over other devices on your network. Check how much data your internet plan actually needs to handle peak gaming sessions.
- 🌍Connect to the nearest server — In most games you can manually select server region. The closer the server, the fewer hops your packets take. Pair this with our Ping Test for Gamers to find your lowest-latency option.
- 🔄Flush your DNS cache — On Windows, open Command Prompt and run
ipconfig /flushdns. This can resolve routing issues causing intermittent packet loss. - 📡Switch to a gaming-focused DNS — Try Cloudflare (1.1.1.1) or Google (8.8.8.8) for faster, more reliable DNS resolution. If you still have issues, check for outages in your area first.
When Packet Loss Means It's Time to Switch ISPs
Some packet loss is fixable at home. But if you've tried every fix and your ISP can't resolve the issue, the problem may be structural — aging cable or DSL infrastructure in your area, chronically congested networks, or a provider that simply doesn't invest in maintenance. Switching to fiber internet is the single most effective long-term solution — fiber delivers near-zero packet loss by design.
It's likely time to switch providers if:
- ❌You've replaced all cables and hardware, and loss still occurs on a wired connection
- ❌Your ISP has sent a technician and found no fix, or refuses to acknowledge the problem
- ❌Packet loss spikes consistently during peak hours (6–11 PM) every day — a classic sign of chronic ISP-side congestion, and one of the hidden limitations ISPs won't tell you about when you sign up
- ❌Your provider serves you over DSL or aging cable infrastructure and won't upgrade it
- ❌You're in an area with only one provider — meaning no competitive pressure to improve quality. Use our Internet Outage Checker to see if area-wide issues are the cause
Use ShopLikeSam's address-based search to compare internet providers at your specific location — including fiber options that deliver near-zero packet loss.
