Sounds like a routing problem. Aha, I was going to write a bunch of stuff, but
just realized I was making assumptions of things you didn't state. So let's
clear those up first:
1) First, can devices on the original LAN router access the internet? Or can
only devices on the WAN access the internet? I assume the LAN can but let's
make sure of that before we proceed doing a bunch of stuff.
2) Since the new N router was set up as a switch, then it's basically part of
the LAN network. So assuming LAN devices on the original router can access the
internet, I don't see why devices on the new N router wouldn't be able to
access the internet since they're part of the same broadcast domain, and
getting the same IPs as the original LAN devices!
a) So a simple troubleshooting idea: take a device from the original LAN
router and plug it into a switch port on the N router and see if it can still
access the internet. You can also take a device from the N router and plug it
into the original LAN router and see if it starts working.
3) If it's not any of the physical things, then start moving up the layers, and
look at IPs now. Could it be that the new devices are getting IPs that are
somehow not being NAT'ed correctly? To see if it's an IP issue, you might be
able to statically assign an IP to one of the new devices from a device that
can access the internet from the LAN and see if that makes it start working...
There's more but that's a good start for now; I mean, at the start it seemed
like it was just a routing problem where packets don't know how to get back to
the LAN from the WAN, but you haven't given enough information about the setup
to be sure of that...hehe, you don't have a Visio of the network do you?! :P
