Why is my New Desktop so Slow?

I've just got me a gaming desktop, an HP Envy yesterday and realized that the browsing and downloading speed are ominously slow. This is my download/upload speed.

Download Speed: 959 kbps (119.9 KB/sec transfer rate)
Upload Speed: 84 kbps (10.5 KB/sec transfer rate)

Restarting the Router did nothing despite having three bars in my room, adjusting the desktop in my room did nothing. I have no idea what is going on.

Meanwhile, my near dead laptop, which runs on the same wifi, still connects with ease.



Second Test


It's a Windows 8, if it helps.

EDIT: Ok, I realized that my internet connection's ok so far, it's the Downloading/Uploading speed that's the main issue.

Isn't comcast stuposed to provide 20 up/down?
