If you're feeling adventurous, dive into your router's advanced QoS (Quality of Service) settings for more adjustments (not every router will have QoS options).

QoS allows you to assign priorities to certain types of traffic so they aren't interrupted. Some routers prompt you to simply enable various QoS features, and then they automatically assign a higher priority to audio and video streams over other kinds of data.

Other routers will let you assign high priorities to specific applications, such as Skype or World of Warcraft. You can also give high priority to a specific gadget. That's handy if you use a game console to play online games and also stream HD movies.

It's a balancing act to get the right combination of high-, medium- and low-priority settings. But with a little trial and error, you should be able to put buffering and lagging woes in the rearview mirror.

If you do all this and the network is still pokey, here are 5 easy tricks to give a boost to your home's weak Wi-Fi signal.
