Open the terminal and use the following command: sudo rmmod iwlwifi It has been observed that disabling the 802.11 n helps speed up the wireless connection in Ubuntu and other OS. While 802.11n provides better data rate, not all the routers support it, especially the older ones. Even after so many years, most of the world runs 802.11a,b and g.
