I have a fresh installation of Ubuntu 16.04 on my Early-2011 MacBook Pro.



The wifi drivers seem to be installed fine but I keep experiencing issues. It's not that I don't have a connection. I do. But at times it gets interrupted, and after a while it returns back to normal. The thing is it happens so often, it's quite annoying (and it has nothing to do with my internet connection, it works fine).



Here are some details of my setup:



lshw -C Network

Any idea what might be going on here or how I could solve it?
