I have a site with wireless roaming printers that have static ip addresses and can roam throughout the building. Several times an hour the print server (in another building / subnet) cannot ping the printer therefore cannot send its print job. Whats odd is that they can ping the printer from the associated AP and can ping from a laptop associated to the same AP. Communication can go down from the server to the printer(s) for several minutes and then just reconnect. I see syn packets leaving the printer but not getting any syn/ack back. I also cannot ping the printer from a different subnet / my vpn connection. Is there any issues with roaming wireless clients and routing protocols / spanning tree that could cause a problem? I can only imagine with mac addresses moving from one AP to another that something could break. The AP's are 1210's with b radios running 12.3(2)JA2.
