Ubuntu – Very slow internet connection on ubuntu 16.04

This problem was present with 14.10, 15.04, and 15.10, I simply haven't been able to fix it.

I'm using Chrome 50 as a browser. I've changed the hosts: files dns line in nsswitch.conf file, and tried other suggested fixes.

My friend with MacOS does not experience the same slowness.

Here is some Laptop info. I'm on a Dell XPS 13 with i3 processor, and I can gladly show more if needed.

02:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b1] (rev 6b)
    Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c470]
    Kernel driver in use: iwlwifi
    Kernel modules: iwlwifi

Thanks in advance!

Edit: some output of sudo lshw
