DHCP gives out-of-range IPs

MN700 is set to give out IPs in the range 192.168.1.50-
100. However, when a client connects wired or wirelessly,
DHCP give the next available address after the router,
192.168.1.2 for example. I have varied the lease times as
well - same thing. This happens with WinXp SP1 or SP2 and
also on my PowerMac. Why arent clients getting the IP
range I set? Worked fine before last firmware upgrade.

Also, DHCP client list shows clients no longer connected,
even after a refresh. That works great if I wanted a log
file instead of current actively used leases.

Any suggestions? Haven't reset the base station yet, but
may have to.
