Check /var/log/syslog when you /etc/init.d/networking restart, and see if you are dropping packets. It would work on reboot because the firewall script almost always runs after setting up networking. Regarding the 'dodgy cable modem', I thought I had a dodgy cable modem, until I realized I was blocking out a particular igmp packet from my ISP. I looked in my logs, and set up a rule to accept the packet from the ISP, and now I can leave my computer on for months (6 to be exact) without any dhcp problems.
