Odd network Question...you gonna love this

OK, here is the setup, I have a Laptop with a wired 10/100/100 jack and a wireless card built in A/B/G.

I have a wireless router at home that does B/G, I connect to it at G. The wireless router also has 5 10/100 ports on the back.

From the wireless router I go into a cable modem, pretty standard setup so far, here is where gets fun.

I have the option of "bundling" my download speeds and upload speeds with the installation of a 2nd cable modem.

What I am unsure opf is how exactle this setup would work. Going to attach a pic and see what you all have in the way of advice:

Basically, the 2 connections from the cable modems are 15down and 2up each, my cable company will allow me to combine the connections (they will set it up on their end) so I have 30down 4up, what I dont know is how top do it on MY end.

I am attaching a word doc with a drawing to explain better. I am running Vista64 Ultimate w/sp1

I read a few posts on a cable hacking website a while back with the guys doing something similar (but with more modems) what you need is a twin wan router something like this - Twin Wan Router TWR XC-DPG502: XiNCOM

Took a look at that and looks great BUT....one connection is wired and one is wireless....doesnt seem to have a wireless on that item.

You will just need to have a look about for a wireless router that has dual wan ports or you could get a dual wan router and add a wireless access point.

I thought about adding a AP to that, but was wondering how DHCP would handle that, I mean would the wireless AP give out the DHCP IP or the dual WAN router ? if the wireless AP, would that just pass through ?
