Setup extra router as switch

    I have a Netgear 3500L configured as a wireless bridge to a RT-N16 (the main router/gateway). I need to add more LAN ports to the 3500L and was planning on plugging in a spare WRTSL54GS to do it.

    From searching I've done I think all I have to do is disable WAN, turn off DHCP? So I leave it in AP mode? Set it to 'router' instead of 'gateway'?
    Also, do I need to use a crossover cable? Or is a regular LAN cable ok?

    Thanks!

    You should not need to make any adjustments software-wise to the WRTSL54GS. Just use the 4 LAN ports as you would a normal switch and don't hook up anything to the WAN/Internet port.

    As for cables, standard straight-through should work, as most ports are auto-MDIX these days. The WRTSL54GS might not be auto-MDIX though; you'll know if you use a standard straight-through and don't get link. :) In which case sure, use a crossover.

    for an extra port I would assign the wan port to the switch.

    Politely I am in disagreement. I would recommend folks apply KISS principle as much as possible -- that means changing as little as possible when using the router in this fashion. I have a hard time believing a single Ethernet port would make-or-break a situation; by that point the customer has probably already invested in an 8-port or 16-port switch. :)

    Turn off dhcp and assign it an ip that does not conflict. If you don't need the wireless turn it off as well.

    Thank you for the replies.

    I may or may not assign the wan port to lan, depends on how many other devices I end up hooking up to the 'net. Isn't it as simple as a checkbox in tomato, looks like it...

    Thanks again :)

    usually when i do this in tomato and dd-wrt, i just disable the WAN interface.

    In my experience, this gets rid of everything(DHCP, firewall, routing).

    Um no, when you disable WAN it simply disables the WAN port, it doesn't turn everything else off because you don't have to have a WAN port to get internet, wireless interfaces can also be used. Here is a guide that explains what you'd have to do. And yes i know its for dd-wrt, but the same principles still apply here.
