I've looked at the settings on the 320's, but with no luck (I cannot access the 6520 at all - I'm locked out). I've was told by our vendor that "Well, DHCP is known to 'just stop working' on the 320's...you need an expensive software upgrade." Not acceptable, since nothing changed. Vanguard (who bought the Motorola Vanguard equipment line) would not even think about the question for less than $600.
