BigBob, Without knowing the particulars of your setup, I'm tempted to say yes; sure, why not, but then again that's a too-easy guess. Without knowing the particulars of your set up, what routers or devices are in play, what firmware and services, etc, so an informed answer requires more specifics. For instance, If you're asking if you can plug a PC into a node with Ethernet or just use a wireless tablet, and it should just work, well, probably, maybe, or maybe not. If you've actually tried it and it works, that means you've done your home work; congratulations. If you're asking because you've tried it and it doesn't work, then the answer is, keep searching. Reading and research will give you the answer you seek.
The forum is a big area to cover. If you've read everything applicable to your model and the FW you use, and you can't find anything remotely similar to your setup in a thread on the forum try rewording your query and provide more details so one of the resident wizards can give you a more precise reply. Cheers.
