Has anyone had their wifi fail on their rMB 12? One day I noticed the wifi cutting intermittently off after a long multi gig airdrop transfer. Now the wifi will only work when the machine first turns on, but after some surfing for a bit or downloading files, the wifi starts to rapidly connect/disconnect. Tried everything to a full machine wipe and still does it. When I turn it off it works for a bit until the machine starts to get warm again and then it's back to crashing. Unfortunately, ifixit teardown looks like the wifi is no longer replaceable like older MacBooks. Am I SOL?
