Browserlagging? video lagging? server?

[lildavidxd]

Hi, its been about 2 days or more i m not sure. but my overall browsing experience seem to be bit bumpy. i been trying to watch several movies off divx player online and it just wont load and i cant even watch videos off youtube. The buffering is just extremely slow. im running a wireless router. i did 3 malwarebyte checks , ad-aware , AVG scans and did whatever i could ... im wondering is my browser casuing this (Mozillia) or what? none of my other family computers are experiencing any of this. and i did a speed test and it showed up fine.. just videos are such a hassle for me. Thanks guys i would appreciate some feedback
