![]() On the other hand, a wired (Ethernet) connection from the device straight to the modem will be about the same as the network speed to your home or building. Over a WiFi connection, speed to your device may vary greatly depending on how close your device is to your WiFi point, as well as any obstructions or distance in between. Speed to your device may vary greatly depending on whether you have a wired or WiFi connection. This speed is measured to and from the device you are using to run the test, which means the type of connection has a big impact on the result. How quickly your internet can transfer that data from the network to your device and from your device back to the network determines your download and upload speed. Even the best internet speed test cant magically increase your home internet speeds.Those speeds entirely depend on the specific internet plan you signed up for with your ISP.That said, there are. Next, the speed test downloads and uploads a packet of data over that connection. The amount of time it takes for that information to make the trip is your ping. Ive installed/configured an Ookla speed test site on a server that happens to still be in production (but not one available for, as you can. You will see the name in the lower right-hand corner of the testing window.Ī "packet" of information is sent from your device to the server and back. The important part is that the measuring time should not be linear to the amount of data received.The internet speed test starts by identifying the network server that is closest to you. That way we always get at least (on average) one package per interval and we will not go nuts if we are on a 10 Gbps connection. This will cause the interval to increase slowly from about several tens of ms up to the time per packet. Var intervalTime = Math.Max(d, Math.Pow(2,(Math.Log10(timePerPacket)))*100) var timePerPacket = 5000 / nrOfPackets // Time per package in ms My process would be something like this, measure for 5 second and gather data, ie bytes recieved as well as the number of packets. ![]() Accessing the Internet on a wireless device via a router may impact the speed of your connection. For the best test result, make sure your computer is connected directly to your modem, rather than your router. If you are writing it for all kinds of connections I would recommend you make the solution dynamic, ie if the speed is high you can easily decrease the averaging interval but in the case of slow connections you must increase the averaging interval.Įither do as recommends by having a moving average or simply increase the sleep up to maybe 1 second.Īnd be sure to divide by the actual time taken rather than the time passed to Thread.Sleep(). Testing your speed while using other devices simultaneously may impact the accuracy of the results. ![]() Given that your speed is 60 KB/s I would have set the running time to 10 seconds to get at least 9 packages per average. I believe the counter only counts whole packages, and if you for example are downloading a file the packages might get as big as 64 KB ( 65,535 bytes, IPv4 max package size) which is quite a lot if your maximum download throughput is 60 KB/s and you are measuring 200 ms intervals. Concat(reads).Take(20) īy looking at another answer to a question you posted in NetworkInterface.GetIPv4Statistics().BytesReceived - What does it return? I believe the issue might be that you are using to small intervals. Var br = nic.GetIPv4Statistics().BytesReceived Var lastBr = nic.GetIPv4Statistics().BytesReceived Var nic = nics.Single(n => n.Name = "Local Area Connection") I like flindenberg's answer (don't change the accept), and I noticed that some polling periods would return "0" that aligns with his/her conclusions. Also, don't forget that any old process might be doing any old thing on the internet these days (without stricter firewall settings). Things to keep in mind are Kbps is in bits and HTTP data is often compressed so the "downloaded bytes" will be significantly smaller for highly compressible data. Here is a quick snippet of code from LINQPad.
