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. Depending on the input parameters, the output can include the DNS lookup results, a list of IP interfaces, IPsec rules, route/source address selection results, and/or confirmation of. It supports ping test, TCP test, route tracing, and route selection diagnostics.

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. The Test-NetConnection cmdlet displays diagnostic information for a connection. 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.

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. Thus, NCSI can neither resolve the domain its test file is hosted on, and even if it could it wouldn't reach the actual file because HTTP traffic is redirected to the Authentication server.The internet speed test starts by identifying the network server that is closest to you. It blocks all ports besides 80 and 443 (for HTTP and HTTPS, respectively), which get redirected to the Hotspot's authentication server and might mess with DNS requests in one way or another. The reason it reports 'No Internet Access' when you haven't authenticated on a Hotspot yet lies in the way a Hotspot works. So, it might also assume proper internet access if this test is successful but the document can't be retrieved. The mechanism also checks whether the domain the document is hosted on resolves to the expected IP address.

If that is not successful, Windows reports 'No Internet access'.

There can be many reasons for failure, like wrong DNS configuration, firewalls, NAT.

NCSI tries to load a specific page via HTTP (more precisely: a text document) and tests whether it can be retrieved. Basically you cant check if computer is connected to internet.

The test for internet connectivity is simple: Windows Vista and 7 have a variety of Network Awareness features, one of which is the Network Connectivity Status Indicator that performs connectivity tests that in turn are used by the network systray icon. Read the May 16th, 2011 blog entry for more details or submit your own Question of the Week.Īfter some digging (the sheer number of network and Internet related services in Windows is astonishing), I think I found it. This question was a Super User Question of the Week. Can anybody explain how this works? I would prefer answers that refer to facts, rather than just guessing, but if you have a really good guess, then go for it. How does Windows know whether or not it has a successful internet connection? Presumably it is checking some online Microsoft service to see whether it has a successful connection, gets redirected to some other page, or doesn't get any response at all, but I haven't seen anywhere that this process or the services used are documented. Sometimes, if the WiFi connection requires an in-browser authentication step, like on many guest networks in hotels or universities, then the following pop-up bubble appears, saying as much: In Windows 7, the notification area networking icon will show an error indicator if there is no internet access, and the error icon goes away once there is a successful connection to the internet.
