networkInterfaceInfo.Bandwidth始终为52 Mbit [英] networkInterfaceInfo.Bandwidth always 52 Mbit

问题描述

如果我尝试获得当前WiFi连接的速度，我将始终获得52 Mbit.

if i try to get the speed of the current WiFi connection i get always 52 Mbit.

这是我使用的代码:

        Dim networkInterfaceList As New NetworkInterfaceList()
        For Each networkInterfaceInfo As NetworkInterfaceInfo In networkInterfaceList
            If networkInterfaceInfo.InterfaceType = NetworkInterfaceType.Wireless80211 Then
                If networkInterfaceInfo.InterfaceState = ConnectState.Connected Then
                    var_WIFI_Name = networkInterfaceInfo.InterfaceName.ToString
                    var_WIFI_Speed = networkInterfaceInfo.Bandwidth
                End If
                Exit For
            End If
        Next

推荐答案

带宽返回值是网络接口的可用速度，而不是接口上当前可用的带宽.

The value Bandwidth returns is the capable speed of the network interface, not the current bandwidth that may be available on the interface.

我敢打赌，此表中的值可以是任何值: http://en.wikipedia.org/wiki/WiFi_N#Data_rates

I would bet the value could be any from this table: http://en.wikipedia.org/wiki/WiFi_N#Data_rates
