An extended ping from the new router to the broadcast address on the LAN
should also refresh all the PCs arp caches with the new MAC address.

On Windows platforms there are two possible ARP cache timers. ARP cache
entries that are actively being used are cached for a maximum of 10
minutes. If an ARP cache entry isn't used the entry will be removed
after 2 minutes.
You could also have done an "arp -d *" as opposed to rebooting the PC.

Subject: arp cache
i have a router interface connected to my lan. their pc's have a gateway
of the ip on that router interface. if i move the ip address off the
current router to a different router on the same lan will everyone have
to reboot their devices in order to clear the arp cache or if i did it
in the evening and their devices were left on all night, would the pc's
arp cache eventually time out or clear with no intervention. thanks
