My 2330dn is connected via USB cable to a Linksys print server, which is connected via Cat5 to a WRT54G wireless router. My wife's Samsung Tab S can access this network and the Internet. I have installed the Dell Document Hub app on her tablet, but when I attempt to add this printer, using its IP address, it can't find it. This printer is on the supported list.
I have been a network engineer for over 20 years. If there were adequate docs (or if I could find them), I could probably figure this out, but I haven't found any manual, user guide or how-to at all, just promotional literature.
