You can measure the speed of your broadband connection from a network using the CyNettest tool located at the following link:
CyNettest measurement tool
It is recommended to directly connect your computer to the modem/router, using Ethernet cable connection. Wireless network (WiFi) may limit performance of your connection.
Before starting a measurement, make sure your broadband connection is not used by other types of software, computer or network device (e.g. IPTV decoder, security camera, torrents, etc). Network traffic generated by such sources may reduce accuracy of your measurement results.
CyNettest uses the M-Lab measurement platform, which automatically assigns each measurement to the closest available measurement server. When the country's all available servers are busy, your measurement may be conducted by a server located in another country. In that case, if you are logged in, the results of your measurement will not be saved in your profile.
