    Dim l As Integer, m As Integer, n As Integer
    Dim i1 As Integer, i2 As Integer, i3 As Integer
    Dim i4 As Integer, i5 As Integer, i6 As Integer
    On Error Resume Next
    For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
    For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66

Limiting network speed on a mobile device

Recently I caught up in a problem where I had to run an application on a mobile devices with limited speed. There catch here was the fact that the application was not available over internet so it was not possible to access it using GSM i.e. 2G or 3G data.

I had to access that application using Wi-fi network only. This was bit challenging as there is no any such app available in the app store and also to modify speed at router level required much of expertise.

Then I came across with this very simple solution.

Route all the traffic using a proxy server and limit the speed on proxy server. One can use his own system as a proxy server and there are lots of free tools available for the same few of them are Fiddler, burp suit, etc..

It is very easy to configure your own system as proxy server using above tool and once that is done you can you limit network speed on your system using free tools like netlimiter or net balancer.

Post that all you have to do it to put IP address of your system in the proxy server field of your device and all the traffic on the mobile device will now get limited to the speed which was set on your system.
