    I tried to set up my Asus RT-N13U (loaded with DD-WRT) as a secondary router on my Verizon FIOS setup using this guide:

    Can I use my wireless or an extra router along with the Verizon provided router? Verizon Online FiOS FAQ | DSLReports.com, ISP Information

    Both routers (Verizon and Asus) default to 192.168.1.1. I connected to the Asus router logged in, disabled DHCP and set a static IP of 192.168.2.1 to avoid conflict with Verizon router. I rebooted the Asus router and now I cannot find it its IP. When I plug a laptop into it, I cannot find the admin interface at either 192.168.1.1 or at 192.168.2.1

    Plugging into the new Asus router or connecting to it's wireless doesn't let me establish a network connection.

    I tried holding the factory reset button down for 10 seconds, but that didn't work (I'm guessing DD-WRT doesn't support it).

    Any thoughts to find the admin interface, or at least wipe / reset it?

    You probably have a default route/netmask getting in the way. Let's say that on your computer you've got an IP of 192.168.1.100 and a gateway of 192.168.1.1 and a netmask of 255.255.255.0.

    This tells your computer that any IP that starts with 192.168.1.x will be local, and anything that starts with anything else will go through your gateway out to the internet. So, if your router is at 192.168.2.1, then when you ask for 192.168.2.1, you can't see if because your computer sends the requests to the internet router at 192.168.1.1 to go out that way, instead of trying to hit the other router locally.

    Set a static IP and netmask for your computer. IP can be something like 192.168.1.100 and then a netmask of 255.255.0.0 which says that when you ask for anything that starts with 192.168.*.* to look locally.

    Then your router should show up.

    Thanks, would you mind explaining how to do this under Win 7?

    Doing the hard-reset should have worked, have you asked on the ddwrt forums if there are any known problems with the 13nu?

    Sure, you want to find the network config dialog. In there somewhere are your tcp/ipv4 settings.

    Pull up your Network and Sharing Center.

    Click manage network adapters in the upper left hand corner

    right click on the connection you want to set statically and choose properties

    double click on TCP/IP v4 and set your settings.

    As far as DD-WRT goes, you have to hold the reset button for 30 seconds to restore factory defaults. If you hold it down for 45 seconds, you will put the router into recovery mode which will enable its tFTP service and you can flash new firmware using tFTP. I, along with most other DD-WRT users, recommend performing a 30/30/30 reset which typically causes the nvram bootloader to be completely restored to DD-WRT factory defaults.
