said by andyross:Since the firmware update, I noticed that DHCP RENEW warning occurs exactly every 84 hours (3.5 days.).
FWIW, that sounds correct for the typical IP lease length of seven days which renews at *half life*. Bear in mind that this "DHCP" message is for the DOCSIS / WAN / management IP address for the modem and has nothing to do with anything connected to the LAN.
