Solved 3 routers in series and a switch?

Specs: N/A
Hey guys I'm looking for some scrutiny here.

My friend is setting up his network and it's a doosy. He has 6mbps coming from AT&T. That goes into his house to (router A) a 2wire wifi b/g router. From there he has a line going to a second router (router B) a linksys wifi N router. From there he has two lines leaving that, one goes to an older linksys router(router C), and the other line goes to a 5 port switch in another room.

To the best of my knowledge here is what's on each router 

Router A: computer, dish network dvr, fax, feed to B

Router B: computer, printer, feed to C and feed to switch

Router C: my Xbox 360, dish network dvr, Sony blue ray,

Switch: Vizio tv, Panasonic blue ray, dish dvr


I am just curious if anyone see's any problems with this. And both wifi routers are broadcasting signal.

what is connected to B has to compete for bandwidth that is connect to C which in turn has to compete for bandwidth that is connected to A. Add that congestion to the hop latency and the farther away from A the slower you get.

I don't believe UPnP on A is going to read UPnP on B which is turn is not going to read UPnP on C. You would need to do port forwarding from A to B to C

But whats the point? I already gave you the correct design.

It's also good I note that he believes that he is getting full 6mbps to everything on his network no matter what. I believe that he might run into ip issues at some point or NAT troubles.

Router C and switch should be wired to the first router.
None of the routers after the first should be connected by their wan ports and doing nat. No need for nat/prevents sharing between segments/slows the network down by adding hops.

What is a HOP? Also, an xbox 360 requires an open NAT and have Anonymous NAT Redirection allowed and is not filtered. As the network sits right now the NAT is as strict as it gets.

Is it possible to have the network stay as it is and everything be working perfectly fine? (my money says no)

To be honest I'm just looking for someone to be real critical of this setup and tell me everything that is wrong with it just to prove a point.

I gave you three reasons in my last sentence. Add to that port forwarding for the xbox is more complicated/prone to failure.

Oh I c now. I was reading ur last sentence wrong. So it prevents sharing between segments? In essence, what do u mean by that? Sorry I know a little bit about computers, not a whole lot.

And I know I could just look it up myself but sometimes it helps for someone to put it in baby words for me.

anything off router b, as an example, will not be able to access a pcs share off router c or d since they are in different subnets and the only gateway listed for a client off router b is the gateway to router a.

Man that's exactly what I was thinkin, I wasn't sure though. Ok next question. This is just something I was curious about. Say at router B speedyest.net gives me 6mbps and 50 on the ping. But at router C the Xbox with a search for games on modern warfare 3 will skip games from 50ms of latency and go all the way up to 250ms latency and connect to one of those.

Also bear in mind that the NAT is strict when connected to router C.

And here's another question. Even if I went into all three routers and changed the NAT settings to open and made sure the upnp setting made exceptions for and xbox, would I still technically have a strict NAT at router C?

I guess it could be the hop from b to c that's creating the latency?

Well like I said this is someone else's network, and they believe that it's foolproof and has no flaws. I just needed someone Besides me to point out that it actually does have flaws. And all the questions I said to you were the same questions I asked the person who owns this network and they wouldn't budge on their "flawless network"

You have helped tremendously Wanderer. I'm new to this site but if there is a way I can give you +1 to your reputation at this site I'll find it.

And your last answer was pretty much a slam dunk on the whole shabang.
