This simple tool is designed to help you pinpoint problems with your Internet connection, but there were some connectivity issues with the program itself.
Internet Speed Test's basic interface has just a few buttons to test upload and download speed, show your PC's configuration, and troubleshoot a host site. Although the program quickly performed the upload test, it wasn't always able to complete the download test. At the end of a successful test, a browser window opens, showing how your speed compares with various types of connections like DSL. This window failed to launch with each of our download tests and didn't always appear after the upload test. Internet Speed Test did effectively pull config information, and this feature consistently worked well.
The program doesn't include a help file or other user guidance to explain the Ask Expert button, which opened a browser window but only displayed the message that the page couldn't be displayed. The publisher's Web site wouldn't open, either. Internet Speed Test is offered as freeware, but its spotty performance isn't such a bargain. It'll cost you nothing to try, but it may not tell you what you want to know about your Internet connections.
Internet Speed Test Diagnostics is a broadband diagnostic tool that helps you quickly perform speed test and troubleshoot common connectivity problems. You can measure both the upload and download speed/bandwidth of your Internet connection. When you have trouble with Internet access, e-mail, VPN, or WIFI or Web proxy, you can run the tests to isolate problems with networking configruation, NIC card, WIFI router, Cable/DSL modem, service provider network, Web server or the applcation itself. It can also show IP network configurations, including IP address, DNS server, DHCP server and local routing table.
