Know Your Connection.

It depends on what you do and how many people share the connection. As a rough guide, 25 Mbps handles a single 4K stream, 50 to 100 Mbps suits a small household, and 200 Mbps or more gives a busy home room to spare. Speed is only part of the picture: low latency and steady performance matter just as much for calls and gaming.

Ping, or latency, is the time a small message takes to travel to a server and back, measured in milliseconds. Lower is better. Under 30 ms feels instant, while over 100 ms is noticeable in games and video calls.

Jitter is how much your ping changes from one moment to the next. A connection can have a low average ping but high jitter, which makes voice calls choppy and online games feel inconsistent.

Data travels in small packets, and packet loss means some never arrive. Even 1 to 2 percent can cause freezing or stuttering in real-time apps. Websites cannot measure true packet loss, so WiFi Ping reports the share of latency probes that failed, which is a useful warning sign rather than an exact figure.

Your plan describes the line coming into your home. Wi-Fi adds distance, walls, interference from neighbouring networks and shared airtime between your devices. Testing next to the router, or with an Ethernet cable, shows how much of the gap comes from Wi-Fi rather than your provider.

Networks are shared. In the evening, more people stream and browse at once, which can congest parts of your provider's network. Other devices in your home also compete for bandwidth. Testing at different times, and saving the results, shows your own pattern.

WiFi Ping measures real data transfer using several parallel connections, discards the ramp-up period, and takes many latency samples. It is a good indicator of your real-world experience. Like every browser-based test, it is limited by your device, your browser, the distance to the test server and other traffic on your network, and it can understate connections faster than about 1 Gbps. The Methodology page explains the details.

Yes. It runs in any modern phone browser on Wi-Fi or mobile data. Remember that a test can use several hundred megabytes on a fast connection, so consider Wi-Fi if you have a limited data plan.

Providers connect to the wider internet through different routes, and some prioritise traffic to well-known test servers. That is one reason results can differ between tools. WiFi Ping lets you compare results over time, across connections and across providers, which is more useful than any single number.

A cable gives your device a dedicated, interference-free link to the router. Wi-Fi shares radio airtime with every nearby network and loses strength through walls and distance. Ethernet is usually faster, more stable and lower in latency.

Loaded latency is your ping while the connection is busy downloading or uploading. Many connections respond quickly when idle but slow down sharply under load. WiFi Ping measures both so you can see how responsive your connection stays when others are using it.

Bufferbloat happens when networking equipment queues too much data during heavy use, making latency climb far above its idle level. It is a common cause of laggy calls and games while someone else downloads. Routers with smart queue management can reduce it.

The test server needs your IP address to send data back to you, so it sees it while the test runs. WiFi Ping does not keep it in a database or attach it to shared images. Our hosting provider may keep standard operational logs. Your saved results, which include the IP shown in connection details, stay in your browser only. If provider lookup is on in Settings, your browser also asks a third-party IP database (ipwho.is, or ipapi.co as a backup) for your provider and approximate location, and you can turn that off.
