Hello list.
I've been having an annoying problem for the last few weeks. I have 6
computers connected through a switch and a D-Link router (all wired).
From time to time, for a reason that still escapes me, when a
laptop (iBook
or my PowerBook) wakes up from sleep, it will complain that the IP
address
it had is in use by another computer. I have DHCP enabled in the D-
Link
router with addresses going from 192.168.0.100 through
192.168.0.199. Isn't
the DHCP server supposed to assign another address when the
previous one has
been taken? What am I doing wrong?
Check the lease time setting in the D-Link router. What is likely
happening is that the powerbook is asleep longer than the lease time,
and the D-link re-assigns the IP address to another system.
The powerbook wakes up and someone else has it's address.
On the powerbook you can bring up the networking pref pane and renew
the lease on the TCP/IP tab. that will get a new IP address and you
can go.
You can also set the lease time for much longer on the router, or
even assign static addresses to the systems connecting to it. This
would be set on the D-link.
