Hi, I've tried to cascade two Linksys routers, but It hasn't worked for me. Maybe you could help. The first one (which has cable-modem connection) is the brand new E4200, and the second one is the old WRT54GCv3.
This is how I want to cascade them:
················· Linksys E4200 ----(wireless)----(Desktop PC)······················· gw: 192.168.1.1 ·············|--(Laptop)·························· · ······|······················|--(iPad)············ ················· ······~······················|--(Home Server)······················ ····(PLC)········································· ················· ······~··········································· ················· ······|··········································· ················· Linksys WRT54GCv3 ················································· (Router mode|DHCP/NAT disabled) --(wireless)----(Playstation 3)···· gw: 192.168.1.2 ·····························|--(Samsung BD-C8500)· ·················································· ·················
However, the WRT54GCv3 doesn't get the IP address from the E4200's DHCP. I've also tried to connect them directly (without the PLC), even specifing an static IP on the second router, but I got the same results.
I've to state I don't want to change the first router IP/gateway parameters because I have a web and game home server working with an static IP and I don't want to put it offline temporarily because of readjusting network parameters.
Thanks for your support!
Solved! Go to Solution.

Thanks, I already knew this solution, but didn't work for me because I was aplying it incorrectly.
I have discovered that the solution for me is this:
DHCP + NAT
Gateway mode (NOT router mode)
DHCP (NAT disabled)
The problem was in the B router, in fact it was much easier than I was making it. I had to put the B router in gateway mode , enable DHCP, and set the gateway IP as 192.168.2.1. Now, from the B router I can access the A router, the Internet, and the devices connected to them, but from the A router I can't access the B router and its resources. I guess if I want to access the resources from the B router I'll have to connect directly to the B router access point.

Thanks for all!
I have another problem. Is there anyway to open ports through UPnP in cascade routers?
Is the LAN-LAN setup the solution for this problem? I had trouble trying to do this (not internet access), that's why I used the solution I mentioned above.

I have successfully tried out the LAN-LAN setup but it seems slower through the PLC than the LAN-WAN setup and the slave router is still unreachable from the master router. I can't neither use UPnP from the slave router and DHCP fails from many devices (iPad and even from my desktop computer), but on PS3 connectivity is much better (NAT 2).
I really don't get the point of using LAN-LAN instead of LAN-WAN. What setup do you recommend for watching videos and multiplayer gaming? Do you recommend using a switch instead of a second router or is pretty the same in connectivity terms?

I already read the link posted before, but I have to say in my particular case it's not fast enough. I get a 16 mbps downstream with the LAN-WAN setup, but a 3 mbps downstream (or less) with the LAN-LAN mode. Remember that between the slave router and the master router I have a PLC because of I have both routers in opposite rooms of my house, and it affects negatively in terms of performance with the LAN-LAN setup. I understand that with the LAN-WAN setup I have different networks, but I suppose that at least in my case I should use this setup because is a lot much faster and better, despiste of the disadvantages. I can still open ports in the main router if neccesary.

It seems has something to do with the way the WRT prioritizes the traffic through its ports, because I've tried other ports and cables and I get pretty much the same results.
I suppose I'll mantain this setup while works and if I have problems related to port forwarding I'll give a chance again to LAN-LAN, maybe using another router (I have a WRT54G2, but I replaced it with the E4200 because it started to hang and lose connection frequently).
Thanks for your advices and sharing your knowledge.
