DHCP issues

Greetings,

A couple of days ago, I started experiencing intermittent internet
connectivity on all of the computers in my home. Symptoms include
having to try multiple times to get to a web page, or periods of
several minutes with no connectivity at all, and drops of the VPN into
my work network.

I have power-cycled all of the equipment -- cable modem, routers,
computers -- several times. The ISP reports no issues or problems on
their end. In Event Viewer on all the PC's, there are many DHCPNACK
errors of the type shown below. On one computer, for example, I have
67 of these in the last 24 hours. These started occuring right when
the symptoms began (6:15 AM on Saturday), and the previous such event
was logged more than three months prior.

The IP address lease 192.168.1.102 for the Network Card with network
address 001D60720A5F has been denied by the DHCP server 192.168.1.1
(The DHCP Server sent a DHCPNACK message).

I'm not sure why the router would suddenly start sending these. Any
suggestions on how to diagnose or proceed would be appreciated.
