Chosen Solution
I have recently bought myself a refurbished early 2015 MacBook Pro, but if I put it through some intensive tasks like playing a game or 3D modeling it will disconnect from the wifi for a second. I have narrowed this down to the computer and not my wifi. I have tried the wifi diagnostic and it didn’t give much info on the issue.
Hi I would try reseating the connections for the airport card using this guide MacBook Pro 13" Retina Display Early 2015 AirPort Board Replacement Also Try cleaning the connectors ( cable ,airport card and logicboard )with some isopropyl alcohol and cotton buds/Qtips If the above doesn’t work you’re I’ll most likely need to replace the airport card or use Ethernet with a adapter Hopefully this helps Any questions please ask Thanks:-)
