I just ran into the same thing today.

I have a Red Hat Linux box that suddenly stopped being able to get proper DHCP responses. So I unplugged it, and plugged in my wireless router instead. Same problem. Tried a different wireless router. Same problem.

Its weird that you had so many different devices fail to get an address. In my case, only a device which was recently connected would fail. Other devices which did not previously have an address could get one. However, it did require resetting the cable modem, which might have factored into your troubleshooting.

Some wireless routers have configurable mac addresses, so one strategy might be setting your router to use the mac address of your Macintosh.

Comcast's response with me was also "pay for our modem." I'm not going to do that until they can offer an articulate, technical reason why I should expect their modem to behave differently.
