I have a Mid 2015 15" MBP that I bought back in December. It works well, except for one issue. When I open the computer to wake it up, it takes a long time to connect to my WiFi. When I try to open a webpage, it will just sit and spin for up to a minute, before it connects. I am not sure if it's been doing this since the beginning, but it has been doing it for quite a while. I have all of the latest OS upgrades installed. I have many other devices that connect to my wireless router with no problems. This is the only device that is having this problem. Wife has a 2012 MBA, and it connects almost instantly. Any ideas on how this could be fixed? Thank you.
