Important things to know about router Throughput and Bandwidth value

The function of a wireless router is to gather data packets and send them to the appropriate device in its network.  The speed and transfer rate of the signals depend on the Throughput and Bandwidth of your router.
Difference of Throughput and Bandwidth

The two terms are commonly interchangeable, but these differ greatly in their meaning.  On a practical application, Bandwidth is the theoretical data transfer you can achieve in a perfect environment where there is no physical obstruction or interference that may affect the connection
Throughput is the actual data transfer that is experienced by the user, taking into consideration interference or hardware and compatibility issues.
  • Bandwidth is the maximum amount of data that can be transferred through a network at a given time.
  • Throughput is the actual amount of data that is successfully transferred in a network at a given time.
When the router is capable of 100 Mbps connection, it is referring to the maximum amount of data that the router’s Bandwidth can service.  To know what the Throughput of your router is, try downloading a file and observe the download progress window displaying the actual data transfer.
Throughput is not constant and almost always has a value lower than specified Bandwidth, as connections are susceptible to several factors, including the number of users accessing the network at a given time, network topology and capability of the hardware all reduce the amount of available Bandwidth.
