Pepwave MAX using wireless and Lan

Hey people, Just installed a new Pepwave router for my father and the wireless works great for his laptop and printer. I tried to plug in his magicjack and it does not work in the Wan 5 port or Lan.
If I plug his magicjack in his laptop it works perfectly…Can you have a wi-fi connection and a Lan connection at the same time? Thanks in advance. BTW, his Verizon 4g 295?) works great in the mountains
near Mt. Shasta, CA…Downloads are approximately 12-14 mbs!! Is there a data consumption meter out there for this router? He is having way too much fun!

The magicjack device would not plug in to a WAN port. Is this an Ethernet based device or USB?
