Need help building network,

I am trying to build a gig a bit network with the following components.

motorola SB6120 cable modem x1
dlink DGL-4100 wired router x1
dlink DIR-655 wireless router x2
linksys E2000-RM wireless router x1

I have 4 laptops, 2 desktops, and 3 xbox 360's plus 2 iphones and 1 ipod touch that can and wish to be on the internet at the same time.

I want to connect the 3 wireless routers to the wired router, and then connect the xbox 360s to the wireless routers, and use the wireless router to both hook up desk tops with wires and then have wireless capability for my 4 laptops and my iphones and ipod. IS THIS POSSIBLE TO DO? and HOW?

thanks,
Tim

Tim, I suggest you invest a little money in a used computer (say, a P4 with 1GB RAM and a smallish hard drive >4GB and two or three Gb ethernet cards) and install one of the many free firewall Operating Systems that are available on the internet.

Personally, I use Smoothwall Express 3.0 on a P4 75MGB with a 6GB hard drive and three ethernet cards in a GRN-PUR-RED configuration (GRN is the local, trusted LAN; PUR is the protected, wireless LAN which requires specific permissions to access GRN but can still hit the internet okay; and RED is the Modem) and Dan's Guardian filtering content.

With an external firewall appliance like this, you can dispense with resource-sucking firewall software on individual computers (you must, actually) and you can not only filter individual users' content, but you can also provide QOS metering to prevent one or two machines from hogging all the bandwidth.

The Smoothwall OS can be modified to access more than one outgoing line, as well. This may be a necessity considering the number of appliances you have.

From what I am trying to read.. Your trying to set up gigabit network using your posted hardware. From what Dngrsone is saying it also sounds like you want a secured wireless network and also a open access network as well? I would strongly advise looking into www.untangle.com or what Dngrsone recommended on Smoothwall. 1 thing i have experienced is to get good quality network cards.. Intel PT series. I have a untangle box that i built that I am using for a firewall and I may soon be using it as my dhcp server in the future.. just to try it out. I dont know much about your wireless routers.. but the easiest way would be to leave dhcp off on 1 wireless and let your main wired router (dhcp server) handle the unsecured traffic and set up rules in your router to restrict bandwidth usage/ time per day ports that can be used and etc. The other wireless router I would secure it. 1 Thing I am intersted in why so may wireless routers? Do you have that big of a area to cover?
