Holy cow! This might be the fix to my problem. I have tried everything...... the Apple Branded headphone adaptor may be the issue here. Over the last 20 minutes I have tried test after test. That dongle may be the problem coming out of sleep mode with it plugged in.
My machine says that it’s connected to WIFI but it can’t get to the internet. the only fix was to reboot. But, pull that dongle and it fixes itself. wake from sleep without the dongle in and there is not issues.
interestingly, I don’t have this problem at all until the battery is 50% or less. Works fine all day with the dongle in or not.
drop that battery to 50% or less and the problem started.
this might be the fix!
