Sounds like your printer is no longer in the same network as your
computer.  When you had a static IP you could setup the printer server
to have a similar IP address as your computer... now the IP address is
set by the DHCP server and is probably not in the same network as the
printer.

Assuming you are running windows... run the WINIPCFG program to see
what IP address is assigned ... a wild guess is that the IP is in the
24.x.x.x region (this is a standard address block for the cable
industry).  Your printer is probably NOT in this area.

A solution would be to put a 2nd NIC into your computer and hook the
cable modem to that, so it will have it's own IP address assigned by
DHCP ... and assign private IP's to original NIC, and plug that into
the hub with your print server (and any other computers).  That also
gives you the ability to make your cable modem attached computer act
as a router (with appropriate software) so that all the computers in
your network can access the internet via your one connection.

Alan,

What Dave wrote is very likely the case. The ethernet print server is yet
another reason that a cable modem should be a router and not a bridge -
unfortunately the cable industry think they loose control (= money) that
way. Unless you want to install more hardware, you should convince your
provider that they need to give you an extra IP address for your print
server. Request that you get it for free, even if they normally charge for
it. In this case you are not hooking up an extra PC (= extra user), so they
should give it to you for free.

Good luck,

I think the other folks hit on some great ideas. The static IP likely
would be the most permanent, and best fix.

Other possibilities include:
Using a different protocol, e.g., ipx/sp, for your printer if its Ethernet
card supports it. That way, whatever your computer has to do with TCP/IP
traffic won't affect the printer at all. This sucks for a couple reasons.

Alternately, see if there's a way to "multihome" your PC's Ethernet card.
This involves assigning multiple IP addresses to the very same interface
(card). This has a couple benefits, including the ability to let you add
your own logical network behind the scenes at will. If your operating
system can do it (check the vendor's home page, search for it), this would
be -great. In the future, for example, you could add a second PC and use
something like a wingate-style proxy to get that one on the Internet as
well. IT also keeps you from having to go through AtHome when you have
problems internally; they simply become your problem.
