The invention relates to a method for detecting network bandwidth, comprising the following steps of: a, using a default bandwidth to download preset data volume from a speed-measuring website to obtain an initial bandwidth; b, applying the initial bandwidth to the control by a load balance module and a flow control module; c, obtaining a present bandwidth and a present maximum bandwidth according to data flow; d, computing an average value of the present bandwidth and the present maximum bandwidth and judging if the computed average value is used as the initial bandwidth to realize bandwidth resetting according to the variable quantity of the computed bandwidth and the present bandwidth; and e, circularly performing the steps from the step b at a set time interval in order to detect the bandwidth in real time. The method of the invention solves the problem that a client is not convenient to configure a router when external network bandwidth is in a dynamically changing environment and applies the detected ba
