I've got a couple network printers and one server on the network set up with static addresses.  everything was working fine until we got a new modem installed and another network printer.  Now none of the printers/machines with static configs are visible on the network (via the admin web page nor am i able to ping the machines)  I haven't reset the router yet but tried everything else i can think of.  just find it odd that even a new machine configured with a different static address is "blocked" out of the network.  any suggestions?
thanks
