I have inherited an Early 2015 MacBook Pro Retina computer. I have been working on it to clean up and install up to date operating system. It took nearly a week to get it up fully. But upon testing it, WiFi is incredibly slow. Download is not even reaching 1mbps.

So, I ordered new WiFi board from Amazon. I will get here while I am in Jaan. I will replace the board when I come back.
