I've got a cable modem which goes to a router, which is, in turn,
connected via ethernet cables to a hub upstairs which goes to two
macs.  My macbook is in the downstairs office, and connects to the we
b
via an airport link.  That link -- via a Netgear WPN824 -- connects
via ethernet cables to the upstairs hub.

I used to be able to access my Color Laserjet HP 2605 flawlessly, but
no more.  I thought having the entire IP address of theprinterwould
allow me to access it, regardless of the IP address theprinterwas
assigned after resetting. Now, jobs just get rejected from my Macbook,
even though the computers upstairs have no problem accessing the
printer.

Any ideas?

What is the _exact_ error message?

All the information is below.  I don't see why I can't access this
printerwith the full IP address -- I suppose the router is the
problem -- maybe the subnet mask?  I really appreciate any help.  I've
been unsuccessful reading all sorts of IP troubleshooting material off
the web, so it might be something basic and trivial enough that they
just don't bother touching on it.  Don't hold back any details, no
matter how obvious it may see  to you.

Thanks!! (data below)

Color Laser HP 2605dn (off Main Router)

Default gateway:  169.254.23.24

There's your problem - theprinter'susing a link-local IP address that
is outside of the subnet of your main router, so it is routing yourprinterconnection attempts to your ISP instead.

I would reconfigure theprinterso that it has a 192.168.0.x IP address.

I tried that -- last set it to 192.168.0.103/102/148 -- none of which
worked. Is it possible that thatprinter(or some attached system) has
to explicitly do something to make the system aware of the new IP?
I'd heard that theprinteritself had to request a DHCP update.

If I have the actual, complete IP address of theprinter(as I do,
obviously), why can't the router find thatprinter?  Does the router
automatically limit accesses to some subnet, and is that subnet
defined by the mask?  And if so, does the router or theprinterhave
to be forced to make an update?

Thanks!

As an aside, I've been looking over the web for a good summary of IP
networks -- DHCP, NAT, etc. -- and it doesn't seem there's one to be
found. They all seem to be missing the "summary" part.

Anyone have any recommendations?

Thx!
