i read some where in the dslreports.com where some of the ISP would track the MAC addresses and give 1 IP to start off with and I think in Comcast's case, max of 5. Once I clone it, the cable modem would think my router is the PC and then my router can manage the DHCP.

Comcast usually only give out one IP address. So when you connect a computer directly to the modem, it'll pull that one IP and comcast will not let you get another one.
If you connected a computer directly to the modem, you'll need to do an ipconfig /release and then disconnect. Otherwise you'll have to wait for the lease to expire before the modem re-issues it to the wireless router.
This has been the case with my setup before

not sure if that is true. because I wasn't able to get it to work LONG before I found out about the MAC clone thing...
Oh I did that since the beginning... It didn't help...

RIP is a hop counting routing protocol for small networks where the diameter of the network is less than 16 hops between furthest points.
I'm not sure what you're doing because I haven't set up a home wireless network. But just fyi what happens in home setups is, the switch directly connected to the modem gets the IP. That switch then does address translation to give the illusion of devices behind it that they each have their unique IP address, where in fact the switch is translating home traffic into it's own IP to send out to the internet.

ditto...
here's what my theory is on how comcast maintains their network.
it all depends on the MAC addys of the devices that attaches to it.
for example, i have replaced my own cable modem more than once. and everytime, i have to call comcast to "register" the MAC addy with them, and have them remove the old cable modem's MAC from their system.
and that's it.
i also think, that once the MAC addy of the modem is registered in their system, i think you can go to another house and plug in modem, as long as that house is receiving comcast tv service, and you are good to go, as long as you dont stray away too far from the comcast head end.
same thing with their DVR service, since technically, they also have MAC addys.

you would think so... (so did I) but for whatever the reason, I couldn't get it to work without the MAC clone... 
Oh well, it's working now and that's all it matters.
