Speed, Latency, Jitter, Packet Loss – the Elements that Define Connectivity
Fast internet is not the same as reliable internet. A connection can measure well on a speed test and still ruin a video call, because of the delay before data arrives, the uneven timing between pieces of it, and data that never arrives at all, which you see as freezing.
Speedify is an app that uses Wi-Fi, 4G/5G cellular data, wired Ethernet, Starlink and other internet connections simultaneously, so a wobble on one of them is covered by the others. Each of those measurements is explained here in plain terms, with how to tell which one is hurting you and what using Speedify does about it.
Speedify keeps you online when your connection keeps dropping.
When the internet keeps dropping, the cause is usually something you cannot fix: a weak signal, a congested access point, a link quietly losing packets. Speedify bonds your Wi-Fi with any second connection, often 4G/5G cellular, and reroutes around it in under a second.
Troubleshooting Connection Issues: Speed – the Source of It All
Everybody is talking about Internet speed. It’s the most common attribute for any connection. ISPs sell packages that promote maximum and guaranteed speeds. Clients like you and me are always interested in more bandwidth. Or at least the most we can afford.
Internet speed refers to how much data you can transfer to and from your devices every second. The more, the better. Do not confuse this with bandwidth, which is the maximum amount of data you can transfer through your connection. Speed varies a lot from one region to another and from one ISP to another. It is influenced by the other factors we’re going to talk about – latency, jitter and packet loss. When talking about countries stats, you can always check Speedtest’s Global Index.
Internet speed issues – symptoms:
- slow downloads / uploads
- buffering videos
- video calls that stutter
- websites / apps take forever to load or refresh
Speed connectivity issues – troubleshooting steps:
- Run a speed test on a wired connection or as close to the router as you can.
- Check the contract with your ISP – are the speeds you see close to what you’re supposed to get?
Solutions for Internet speed issues:
- Restart your device and the network equipment – modem, router – if possible.
- Use wired connections instead of Wi-Fi, as much as possible.
- Move closer to the Wi-Fi hotspot.
- Update router / modem firmware and your computer’s network adapter drivers.
- Using public Wi-Fi? It’s possible you’re stuck on a bad hotspot. Connect to another network.
- Combine multiple connections at once using a channel bonding solution.
- Upgrade to a superior plan or change your ISP.
Troubleshooting Connection Issues: Latency (Lag) and Jitter – a Gamer’s Worst Enemies
Latency (or lag) refers to how much time it takes for data to travel to its destination and back. So, it’s a delay indicator measured in miliseconds. The lower, the better. Latency and bandwidth are the main components that influence Internet speed. Best case scenario: low latency, high bandwidth.
Jitter is the fluctuation of latency over time – the deviation from your average latency. It’s also measured in miliseconds, with lower being better. Think of jitter as lag spikes in gaming. It appears when network packets don’t arrive in the same order they were sent, so they’re queued up in a buffer.
Latency / jitter issues – symptoms:
- websites / apps take forever to load or refresh
- slow gaming
- latency spikes in games
- huge delays (with spikes, if jitter is high) between broadcaster and viewers in live streaming
- sync issues and freezing video calls
Troubleshooting latency and jitter issues:
- Measure your latency and jitter. Run a speed test that offers such data.
- Is the latency under 100ms as a general rule?
Solutions to minimize Internet latency (lag) and jitter:
- Restart your device and the network equipment
- Use wired connections instead of Wi-Fi or cellular, as much as possible
- Using satellite Internet? Try to switch to cable or DSL.
- Update router / modem firmware
- Connect to another Wi-Fi network
Packet Loss and How It Affects Internet Connectivity
Packet loss occurs when one or more network packets fail to reach their destination. It is measured as a percentage of packets lost vs. packets sent. You can read more details about the causes of packet loss.
Symptoms of packet loss:
- videos stuttering, buffering and even disconnecting
- unintelligible calls
- fragmented gaming experience
- dropped frames when live streaming
Troubleshooting packet loss:
- Depending on the symptoms, you might be able to get data from the apps / software you’re using to live stream, play games, etc.
- If you want to get a general idea on how lossy your connection is, check out this test.
How to fix packet loss:
- Restart your device and the network equipment.
- Use wired instead of wireless. Wi-Fi and cellular are more prone to packet loss because of their nature.
- Upgrade firmware for your modem / router.
- Eliminate any source of electromagnetic interference – other wireless devices, motors, etc.
- Set up your Wi-Fi network to a less crowded channel.
- Use 2 or more connections together at once.
