How do I limit the WiFi bandwidth broadcast by my router?
Setting QOS on a Router (wlan router 04 image by pmphoto from

To limit Wi-Fi bandwidth broadcast or throughput on the router, a router with the capability to set Quality of Service (QOS) priorities is required. There are many home routers that support QOS, such as the Linksys WRTP54G and the Netgear WNR834B. Generally, incoming and outgoing traffic comes through the router on specific ports. Setting the QOS priorities enables the router administrator to control bandwidth traffic by setting certain ports or device MAC addresses to high priority and others to normal or low priority. These settings will give high priority devices and ports first access to bandwidth, while limiting bandwidth for the lower priority devices and ports.
