How to fix my laptop's slow internet connection? Lenovo Ideapad Yoga 11S?

It's only my laptop. Other laptops have okay internet connection.

According to speedtest.net:
Ping: 37 ms
Download speed: 1.09 Mpbs
Upload speed: 2.62 Mpbs

Youtube videos start off blurry and slow, and downloading things takes forever.

Is there anything I should uninstall or update? I have Windows 8 and use Chrome. This is a relatively new laptop.

I have CCleaner, Malwarebytes, and Avast. I scan and clean my laptop regularly.

Make sure you have the latest wireless driver. If an integrated adapter the driver should be obtained from the laptop manufacturer's site; else from the external card's manufacturer. If you already have the latest driver use Device Manager to uninstall it; reboot the computer and let Windows discover the adapter and reinstall the driver.

Do you connect to the internet through Wi-Fi?
