Hi! I'm running a Macbook Pro mid-2012 and MacOS Sierra 10.12.5. My wifi connection is pretty bad. It's unstable, it's slow. To get it better I have to disable wifi and re-enable it which sometimes makes it a bit better for some time. On the other hand the same wifi works very well on my iPhone and when using ethernet cable with my Macbook. I've already tried those tips from http://osxdaily.com/2016/09/22/fix-wi-fi-problems-macos-sierra/ Any ideas why my Macbook's wifi sucks and how to fix this? Thanks.
