The Problem: You have a ton of great multimedia content on your laptop, but you can't seem to stream that content to other devices.
Quick Fix: Streaming files such as videos and music from one device on a network to another is one of the most common networking tasks home users want to do. Protocols such as DLNA make it easy to stream content between computers, set-top boxes, and other devices.
If you are having problems streaming, there are two settings you need to make sure are enabled on the router: UPnP (Universal Plug and Play) and DLNA (Digital Living Network Alliance). UPnP allows networked devices to discover one another. Newer routers and devices also use DLNA for easy streaming between devices. Both can be enabled through a router's interface.
You can also look for two settings there called WMM (Wireless Multimedia) and QoS. These can help you tweak your multimedia content streaming. Both these features differ from router to router, so consult your device's documentation and online guides.
