Dell Support must verify the ownership and warranty status. Click the blue "Get Help Now" on the right to start a private live chat session. Share the private monitor Service Tags with them.
Two U3225QE in a daisy chain. The Ethernet cable should be connected to the first primary U3225QE RJ45 port.

I encounter the same problem.
Test #1: Connect just the primary monitor
Status: LAN Works
Test #2: Connect just the primary monitor, then connect the second monitor to the laptop directly
Status: LAN Works
Test #3: Connect just the primary monitor, after connection, daisy-chain it
Status: LAN Works
Test #4: Daisy chain it first then connect the primary monitor to the macbook
Status: LAN does not work
In all cases, the ethernet cable is connected to the primary monitor.

Hi Rookie i should return two of the same serie for that issue, i chat Dell over 2 hours and they didn't have a solution like a firmware or whatever else, i should return them U2725QE and U3225QE for that exactly reason, it's a shame because there was two excellent displays talking about image and colors.
