Okay well recently my sister bought a laptop.. She has been on it 24/7 and whenever she is on it she is alway watching youtube videos, uploading her "OMG Look at my dramatic Mirror poses pictures" to facebook, so as you can imagine it LAGS THE HELL OUTTA ME EVERY 10-15 seconds making it impossible to play CS:S I know there is something called "Quality of Service" but I have no idea how to do it and I could not find any guides on how to do it just what it did. I have a netgear WGT624v2 So what should i do?
