Have to turn wifi on and off constantly

I bought a new 13" Macbook Pro with Retina display just before the new year. Now, the wifi does not seem to stay connected. Every minute or two, in order to load a new webpage, I have to toggle wifi off and then back on again. This entire time it says I have stayed connected (I have full bars, in Network preferences it displays the green connection symbol) but when I click on the wifi symbol in the top right it alternates between saying "Wifi: On" and "Wifi: Looking for networks".

I know it isn't my home wifi as my roommate's Macbook Pro works perfectly, as do any guests who come by. As you could guess it is super annoying to have to toggle wifi off and on again just to load a new facebook page or a new google search. Also, I will have to toggle wifi to load the netflix website but once it is streaming there are no problems, so again it doesn't seem like my home wifi is cutting in and out of service.

Does anyone know what I could do to fix this?

Things I have tried:

- Deleted all other networks except my home wifi, to ensure it is not trying to connect to another.

- Tried creating a separate location within Network Preferences. Within the advanced options I changed the DNS servers to "8.8.8.8" and "8.8.4.4" as well as manually configuring the MTU to 1453 instead of 1500 (as per the instructions I found on the OSx Daily site to fix Wi-fi Issues with El Capitan: http://osxdaily.com/2015/10/16/fix-wi-fi-problems-mac-os-x-el-capitan/)

Many thanks to anyone who has a solution!
