Here are a few potential causes of high latency: Dead zones If you’d rather not run a cable, you now get to go down the “wifi performance debugging” rabbit hole. You can buy really long cables, and stick them to your wall using wire clips like these to keep them out of the way. The easiest and most likely-to-succeed fix, if practical, is to connect to your router via an Ethernet cable. If your blips don’t look good, it’s time to try improving things! My wired connection shows pretty consistent sub-5ms blips, and my wireless connection is pretty consistently under 10ms but with a bit more jitter.
Once you have it, plug it into this “blip” tool which repeatedly makes small requests to your router and plots how long it takes to get a response.

The IP address will be a series of numbers separated by periods, like 123.45.67.89. To test local network performance, you’ll send a small bit of network traffic from your computer to your router and see how it performs.įirst, find your router’s IP address by following these steps. The first step is to understand which part(s) of your network are the problem. More moderate jitter can be caused by fluctuations in queueing time, when an intermediate node in the network waits for a while before forwarding your packet because it’s received a temporary surge of traffic from elsewhere.Īt a high level, your goal is to make sure the latency and jitter between you and your friend are as low as possible, and that the bandwidth between you is large enough to carry your video and audio. This is what causes the dreaded “sorry, you cut out for a minute-can you repeat that?”Įxtreme jitter or packet loss are most often caused by a network link failing. This is called packet loss, but from the point of view of video calls, it usually has a similar effect to extreme jitter, in that it will cause the video/audio to cut out for a little while, and possibly to skip over some audio when it resumes. Sometimes packets of data can be not just delayed, but lost entirely. That 500 millisecond buffer will show up as lag.

If your video call software observes that every tenth packet takes an extra 500 milliseconds to arrive, it will leave a 500 millisecond “buffer” between when it receives a normal packet and when it displays the data, so that when the 10th packet is delayed, it won’t need to stop the stream. For calls, it’s important for latency to be low not just on average, but consistently, because audio/video lag is determined by the latency of the slowest packet in the stream. With high enough latency, it can be really hard to have a fluent conversation, because every single silence feels awkwardly long and triggers your conversational instinct to fill it with chatter.Įven if it’s not noticeable, though, latency is one of the things that contributes to video calls feeling “off,” because everyone’s reactions to what you’re saying are delayed by a few beats. High latency manifests as lag, where it takes your friend a while to start talking after you stop, because the audio took a while to come out of their speaker. Latency, the time it takes to send one “packet” of data across the link. It’s important that your bandwidth is enough to transmit video and audio at the quality level you want (and to accommodate any other simultaneous users of your network), but beyond that, extra bandwidth won’t help. Streaming a standard definition video already requires 3 Mbps.

Most internet plans that aren’t dialup or low-end DSL will support this.įor instance, Zoom needs only 600 kbps of upload and download bandwidth for “high quality” 1:1 video, and tops out at 1.8 Mbps (megabits per second).
Bandwidth is divided into upload (sending data from your computer to the Internet) and download (the other direction).ĭespite marketing and much of the Internet’s advice, bandwidth is probably not the thing making your video calls suck, unless you’re on a bad phone connection or someone else on your network is streaming video or something. When analyzing the quality of a network link, you care about three things:īandwidth, the rate at which data can be sent to the person you’re talking to. If you’ve solved your own network problems but the person you’re talking to hasn’t, just send them a link to this post :) When you video call a friend, the data (audio and video) are sent from you to your friend over many different network links between different devices:Īny one of these links can have a problem, although you will mainly care about the ones on your side (the top half of the diagram) because they’re the ones under your control.
