Packet Loss Test

How to Fix Packet Loss

How one fixes packet loss depends upon what is causing the packet loss. Honestly, I get the impression that packet loss is usually the fault of Internet service providers (ISPs). If this is the case, there's nothing you can do about it other than convincing your ISP to fix their issue (often a daunting task) or to switch ISPs (sadly not an option for many). However, you can troubleshoot your issue anyway to make sure it's not your fault. Maybe that will help convince your ISP too.

First, make sure you're not just overtaxing your connection. Try doing more tests with smaller sizes and less frequent packets to see if it works well with less intense usage. You also might check if you are using too much bandwidth:

If your usage is high compared to your maximum bandwidth, try using less and see if that fixes the packet loss. Or you could buy more bandwidth from your ISP if that's an option for you.

Next, test all of your hardware. Try plugging your modem (or wherever your ethernet connection comes from) directly into your computer if possible. If that does fix it, then try replacing your router or wireless card. If that doesn't fix it, you could try using a different cable, network card, or computer.

If that doesn't fix it, it's probably on your ISP's end, and it will need to fix it. You should try calling them, letting them know your problems and what you have tried, and praying they will do something about it.
