Please let this fix the issue with glitches after being docked
Just experienced my first OS X issue in a long long time. Upon wake up wifi is on, but cannot connect to the internet working when docked. (OWC Thunderbolt 2)
Supposed culprit is the use of the display port and cables in relation to the wake up issue. When it happens, one cannot even select WiFi in system preferences.
Reading solutions on the internet wasn't too helpful/ no final fix. People complain this has been going on for years now.
Eventually, I decided to just pull the DisplayPort plug. Reboot my MBP, which makes everything (WiFi and Internet) come back as normal and then reconnect to the dock.
Works for now. Checking with OWC as well.
