On my Windows 7 Platform - List item Type at the Windows 7 search bar Network and Sharing Center. Select - Network and Sharing Center Change Adapter Settings Right Click ( The LAN Lannetwrk Adapter) select Status it will show you the speed you have negotiated with the next network device up stream.

How can I test the speed of a LAN? I hope there is something baked into Windows to do this, because I am unable to install any third-party products.

Go back to speedtest.net for another speed test [Average post-fix test ~ 20Mbps/~5Mbps] My quoted speeds are 20/5, so after this fix, I get my full bandwidth; however, if there are other devices active on the network, the second test will give you a good idea of exactly how much traffic the other devices are using.

To troubleshoot a network problem I would like to inquire the real network "speed" for a given network adapter, which can be seen when opening the "status" of a network connection under Windows: Ho...

The only way to test the entire home network without expensive software or hardware is to take your laptop and plug it directly into each router, hub, and switch, and run a speed test through each one. The bandwidth you get on the speed test also depends on how much of the Internet in your home is currently in use.

We've performed numerous test and it boiled down to the Operating System. If we go from Ubuntu 11.04 to Ubuntu 11.04 (same with CentOS for Linux machines), the speed throughput is ~938-941 MBits/s constant. If we go from Windows 7 x64 SP1 Ultimate to Ubuntu 11.04, it varies from ~440-475 MBits/s.

I ran my Internet connection through SpeedTest.net which claims that it finds out the actual Internet speed, much lower than that promised by my ISP. But—while downloading—the speed is much lesser than the test results. Even after using download mangers like Internet Download Manager, there isn’t much difference.

Please add the OS and router model you have. BTW, you can connect the laptop both wired and wireless (eventually with a virtual network device), and test the transfer data speed between the two connections (The bottleneck is the wireless connection).

But no, the connection speed is just fine. ... Speedtest directly on the router too results in about 250 Mbit/s. I already tried pruging speedtest-cli, rebooting the server and so on. Any idea what is going on here? How is it possible, the commandline spedtest fails this spectacular, while the rest of the network setup is just fine?

Is there any way to measure precisely bandwidth between two computers in a LAN?
