How to use OpenSpeedTest Network Speed Test Server? You need two devices in between your WiFi router.

When you run a speed test. Are you experiencing slow internet usage? Endless buffering? Probably due to a congested wifi channel. You may need to change your WiFi router location or adjust your router settings. OpenSpeedTest-Server is here to help you to improve your internet experience. Test Your WiFi (Wireless) or Ethernet Connection (Wired Connection) and Fix your local network before pointing fingers towards your ISP for a slow and sluggish internet experience. Introducing HTML5 Network Speed Test Server for iOS. For Headless/large-scale deployments, Docker image and Source Code are available. Why do you need to Create Your Own SpeedTest Server? You can run OpenSpeedTest Server in your Home Lab, Office Server or Cloud Server. So that you or employees who work from home can run a speed test to your office and make sure they can run everything smoothly. Choosing between ISP1 & ISP2. Sometimes your ISP2 is Faster than ISP1 when you test your speed on popular speed test sites. But when you connect to your Home/Office/Cloud, that slower connection may perform better. The only way to find out is to run a speed test against your infrastructure. Troubleshooting network issues. It is common even when your Internet connection is working fine, but some of the devices in your network may experience trouble getting decent connectivity to the internet. The issue might be the wrong VLAN ID or Faulty Switch. If you run a Local network speed test, you can find and fix these issues easily. Before you add a repeater. Most repeaters will reduce your network speed by 50%, so if you put it far away, it will perform worse, and if you put it too close, you will not get enough coverage if you run a Local Network speed test. Depending on the application requirements, you can decide exactly where you need to put your repeater. Browsing experience. Many useful browser extensions are out there that we all know and love. But some of them are really slowing you down for a few seconds per page you visit. You may see good performance when you test your network performance via File Transfer or Command-line utilities, but you may experience poor performance when browsing the internet. This is due to a bad browser configuration that includes unwanted extensions installed. From my experience, only keep the one you are going to use every single day. Extensions that you may use once in a while should be removed or disabled for maximum performance. If you see poor performance, try OpenSpeedTest from Private Window or Incognito Window. This tool can be used to check the browser performance and impact of Extensions on your browsing experience. No client-side software or plugin is required. You can run a network speed test from any device with a web browser that is IE10 or newer.
