Q: Problems with wifi on Macbook Pro Retina late 2013

Hi everyone.

I've had a lot of trouble with my Macbook Pro Retina late 2013, that i discovered recently. The wifi-perfomance has always been bad, but not something i have noticed so much since i only used an AC-router, or ethernet. At home, i recently discovered that my Macbook wasn't able to connect to my Wifi-router using the N-standard. It's only connecting as an N-device, and all my other devices at home for example my Mac mini 2011, which is connecting to the router using the N-standard.

Other problems i've noticed, is that the connection is very unstable. I know that theres been many issues with the wifi on the Macbook pro retina, but it doesn't seem like the issue has been solved using wifi-updates. Is there a fix out there that any of you know works?

Best regards
