Just picked up Nexus 7; I have wifi, but can't set up.

Hi, I picked up a Nexus 7 from a co-worker today. I was able to do a factory reset, expecting to go through the Android set up process, but did not see it. Is there something that I need to do to get this working?

Under the details, it shows I have Android version 4.1.1 Model number says "Full Android on Grouper"

Co-worker said that he bought it off of ebay, so I don't know the history of this thing.

Thanks in advance for your help.
