This doesn't matter what router you use. The bandwidth manager functionality mostly depends on your network topology. Let me explain how it works. The Bandwidth Manager works in client-server model. This means it consists of two parts: the user interface (what you see) and the system service that runs and does the job. When you run the Bandwidth Manager GUI it asks you for a host name (e.g. localhost) and password where the service is running. The service must be installed either on a Windows based Internet gateway, or a Windows based bridge between the router and the LAN. Alternatively, it can be installed on every client PC but this is a poor solution. In other words, the service must be able to see and filter the traffic that you want to limit.
