Third party USB Ethernet adapter won't wake up I have a mid 2015 Retina MBP 15" and regularly use multi screens and hard wired ethernet. So I've bought a third party HandAcc USB ethernet adapter with Realtek 0x8153 chipset (the device also includes a 3 x USB port hub).

Waking up after sleep the USB hub seems to be working, but the Ethernet has disconnected and won't reconnect without hot (un)plugging. This is particularly annoying if I have hard drives connected to the hub as they will disconnect (seemingly still working after waking).

Has anyone had this or a similar problem and found a decent solution?
You cannot allow the Mac to sleep. That is the fix. If you do, just make it standard operating procedure to unplug and re-plug. Been using Mac Pro's for music production for many, many years. This is not a problem, it is just how they work. Same as you can't hibernate a Mac, and you can't wake one up from LAN.
What seems to work on various systems (sometimes)is to have a Mac USB Keyboard directly connected to the computer and then have your items connected to the keyboard's ports. You need a powered HUB for you can't draw power from the keyboard.
