This has been documented most often on Roger's network.

Subject: Problem with devices releasing and renewing leases too frequently
I have a strange problem on a few cable networks that mainly involves Belkin
devices. A cpe device with do a complete dhcp transaction
(discover/offer/request/ack) and then after it has accepted the addres it
will issue a dhcprelease and repeat the cycle. The frequency of
is in the range of every 22 seconds for some devices. here is a list (most
logs only span 24 hours) of the amount of releases along with the OUI's.
Doing a firmware update on one router resolved this issue. I was wondering
anyone else was seeing this. We first noticed it while tailing the dhcplog
troubleshooting a different issue. We saw a large amount of repeated
releases from the same mac address, and investigated further.
