UNSOLVED
P3223QE, MacBook, Ethernet fails on wake up
I noticed another problem: because of the abovementioned issue, I have been screen-locking my laptop (Macbook) to force the monitor to enter standby mode when I leave it (I am already quite ok with this solution, despite I would prefer to effectively turn off the monitor). However, for the second time now, when I come back and wake everything up, the ethernet won't work. The first time this happened I did a couple of things, like restarting my computer, turning off and on the monitor, etc. Eventually the ethernet "woke up" and resumed its normal operation.

OP, any luck with this one? I'm experiencing the same issue with the same setup.
@user_a21dd1 Hi there. Thank you for posting.
I forgot to give feedback here. But now, I don't remember what I did. In fact, the issue hasn't come up again.
As of now, I have 'Wake for network access' set to 'Only on Power Adapter'.

Thanks for the update @niant.
I'll try the same and report back. In case it helps anyone else, what I've been doing so far when this happens is I remove the usb-c cable wait a few seconds and then plug it back in which seems to cause the ethernet to reconnect.
@user_a21dd1 yeah, unplugging and plugging it back would resolve the issue for me too, but I wasn't prepared to accept that ;) as it was happening too many times.

Been about a week and looks like 'Wake for network access' set to 'Only on Power Adapter' works. Kinda curious as to how much energy I'm wasting but this will have to do for now. Thanks @niant !!

@user_a21dd1 I bet it wastes almost zero, but yeah, this is not the perfect solution, but a nice workaround. Glad I could help, Cheers!

Can you replicate the Ethernet "wake" issue on a Windows OS PC?
Per the P3223QE Drivers & Downloads --> Operating system page (no Apple) and the FAQ Dell monitor and Apple, the P3223QE was not tested/validated on Apple.
