EX2 Ultra not visable on WD Access (OSX)

I’ve been running a EX2 no issues; recently purchased a new EX2 Ultra. Did a fresh format and install. No problem accessing the old EX2 using WD Access on OSX Yosemite 10.10.5. However can not access the EX2 Ultra using WD Access on the same machine (OSX Yosemite)…it’s just not showing up at all…I’m running latest firmware. FYI, I can see it and access it on my Windows 7 machine no issues there.
???
Feedback is appreciated.

Hello,

Have you tried resetting the unit? Make sure to reset the router as well.

Are you using a static ip or dinamic ip

Check your router and see the IP it acquired. Did the firmware updated in the mid.
