so i just fixed my internet connection a while back. All i had to do was restart my DSL modem, and then activate the modem through my pc by accessing the IP address through Internet explorer.

Everything seems to be working fine, but whenever i watch videos, for example, from youtube, the downloading speed in significantly slower. It used to be alot faster, like no interruptions to download more data.

Is there something wrong with my computer? or do i need to look into my modem again?
