    I have 2 routers, NetGear WNR3500L.

    Primary router has WAN connection and 3 wireless networks (all work and can connect to the Internet). I connected a secondary router following this ( using a LAN port to LAN port ethernet cable and it works fine, for the first wireless network.

    But, the second two wireless networks (guest, and home-automation) on the secondary router can not get a DHCP address. Even if I specify a static address, they still cannot get to the internet.

    So, is it possible to have 2 routers (wired together) both providing the same 3 wireless networks, with DHCP and DNS being provided by the primary router ?

    I can provide more detail, but thought I should get this answered first to see if its even possible.

    Thanks in advance for any help offered.
    Cheers! txtomato2

    Wow, learnt a lot in the past few hours.

    To answer my own question, yes it is possible. I already had VLANs set up matching on both routers, but the bit I was missing was VLAN tagging, and a bug where the GUI shows the ports for the VLANS that don't match the output of robocfg show.

    So everything appears to be working. 3 wireless networks, both configured the same on both routers except for different channels. 2 routers wired together, and full internet access working on all 3 networks on both routers. I'm happy, I've been battling this for about a week.

    Just to re-iterate and confirm. Yes, yes you can.

    At another home I did something similar and setup two routers connected via ethernet. Both routers located in different locations in the house and both running the same SSID's and passwords even, different channels however. One forwards all DHCP to the main router, acts like a WiFi extender. Works really well and automatically switches users depending which side of the house they are in.
