I just got through, about a month ago, helping a friend set his up (same
as yours, WNDR3400v2 N600). He wanted to access it wirelessly with two
laptops, print through it wirelessly, and access a shared USB HDD for
storage. Unfortunately, he's got ALS and is confined to bed (he uses
Dragon Speaking for PC control), so he asked his neighbor to do the
hardware hook-up of it, and neither one of them is very knowledgeable (or
patient) about that kind of set up.
By the time I got there, I had to reset everything to factory and start
from scratch. The PC hook-up went OK, and so did the storage drive. The
printer (an HP OfficeJet of some flavor; I don't remember the exact model)
went fairly well. Once I had setup the IP range for the router, I had to
re-enter the IP for the printer, then told it to connect. It worked fine,
and each laptop "found a new printer" when prompted to. So that was fairly
easy, too. I never had to physically connect the printer to the router or
to any of the laptops (running Win7) to make them all see each other.
The problem we had with the router (and the reason he returned it) was
that the internet side of it was very flaky. It worked fine the whole day
I was there, but the next morning, wouldn't connect. He had his wife power
off everything, then start the power on process (like in your other post)
and it worked OK for about half the day. I went back over and spent time
on the phone with Comcast and Netgear, and of course, all they did was
blame the other. I brought him my old Netgear (WGR614v9) to use
temporarily (which worked fine for him the whole time he had it; just no
USB port for his storage drive), and took the N600 home and set it up for
me to use. I had the same problems with it that he had (I have Charter, so
it wasn't totally the ISP fault
), so we concluded that the router
itself was flaky.
He brought it back to Staple's and they traded him for another router
(same one). I set it up at home with the IP addresses and everything that
he had before, went over and plugged it in, and it worked just fine- for
two days. Then, the same problems as the old one; periods of limited or no
connectivity, having to start rebooting everything a few times daily. He
brought that one back, too, and got another model (also a Netgear, but I
don't recall the model) that was so easy to set up, he didn't even call me
until he was done. His wife and neighbor did the legwork for him, and he
did the rest from bed.
All in all, I like the Netgear line, but that model just was not good. If
you are wanting to plug a non-wireless USB printer into it, I don't see
where you'll have a problem with that aspect of it. Depending on the
printer, you may have to temporarily connect it to each PC to install the
software, but then it should be recognized as a network printer once it's
connected to the router. I had to set up my DeskJet 3050 that way, but
once it was recognized in Windows, I have it across the room, accessible
wirelessly.
