Connecting two WRT54G

    Hi, I would like to connect two WRT54G, the first one as a router, and the second as an access point and hub.
    The first is connected to DSL and have the wireless option enabled, WEP 128, SSID is myssid, and CHANNEL 6.
    The second one will be connected to the first one by cable, from one ETH output to the uplink input in the second unit.
    I would like to configure the second with the same characteristics than the previous one, in order to access the wireless as a another zone.
    Is my theory correct? Can I use the same channel?
    Please any help will be welcome.

    Hmmm, what exactly do you want? Bridging between your two routers or routing. There's a difference. The first uses two netwoks, the second only one.

    First of all, it is importand which firmware you are running. When using the official one and you connect the one of the 1st router's lan ports to the wan port of the 2nd router, you have to enable routing which will result in to different subnets.

    DSL -- WRT54G Network 1 ----- Network 1 WRT54G Network 2 --- PC

    You should use router mode and not gateway, since last would translate all addresses behind the 2nd router to the outside interface of the 2nd router (NAT) and you must set port forwardings when you want to access clients behind it.

    Easier is this solution:

    When connecting one of the 1st routers lan ports to one of the 2nd router lan ports, you have a wired bridge and can use one single network.

    DSL -- WRT54G Network 1 ------ Network 1 WRT54G Network 1 --- PC

    Assuming you are running an official firmware which only supports AP-mode on the WRT54G for wireless, you should use different channels on the routers with at least 6 channel difference. E.g. 1 and 7. So you don't get interferences 'caused by overlapping frequencies.

    What do you mean with other zone?

    Thanks, DevilStick

    I only need extend my home network, I think the second solution (bridge) is correct for me.(only one network)

    I use official firmware(for now), If I configure one with channel 7 and the second one with channel 1, the question is, if I travel with my wireless laptop from the zone of wrt54g one to the second one, I loss the connection?

    When I mention zone, is the area that I have wireless connection(I dont know the correct word)

    What is AP?

    Thanks in advance

    AP = Access-Point

    Well, what you want is roaming. Travelling between APs and the wireless clients chose the one with the best signal strength.

    The WRT54G should support the 802.11 standard Multi-Channel Roaming.
    You must set up both APs with the same SSID but different channels. The wireless client connects to the one with the best signal strength.

    Thank you very much.

    I will install as soon as posible.

    this seems like what i have been wanting to do (2nd option).

    Thus, is this like using a wired bridge to extend the network wired and wirelessly?

    Will I be able to use the remaining ethernet ports of the 2nd router to hook up to a desktop PC, etc.?

    Does the first router have to be a linksys? If not, what requirements does it need? I have a netgear wrg634u

    Can you give us more specific steps on how to do this?
    Are there any settings to change on the first router?

    On the second router:
    Do i disable DHCP?
    Do I use the ip of the first router as the gateway of the 2nd router?
    On the basic settings section, under internet connection do i select None?
    You mentioned doing this on official firmware. What if I have say Alchemy? Is there something in that firmware that will make this easier?

    Hi superflysocal...

    I'm not an expert, but the solution (bridging) that Mr. DevilStick gave me, worked for me.

    I did the following

    Router 1 nothing

    Router 2 (the new one) from factory default
    Connect a PC to LAN port
    Change Local IP address from to
    Change DHCP from enable to disable
    Save configuration
    Power off
    Connect an ethernet cable from LAN port of Router 1 to LAN port of Router 2
    Power On

    Test wire connection to router 2, remember the new address is
    Then I changed the wireless setting identical than router 1 except for the channel, from 6 to 1

    Everything is working perfectly

    Good Luck and Regards

    Hi superflysocal!

    The wired extension of two routers as bridge should be no problem no matter what modell.

    Does your netgear have a built-in switch? I assume so. So you just have to connect one of the netgears switch ports to the linksys switch ports. Thus you just extended your network segment over two switches.

    All clients are in the same IP network and you can use all other free ethernet ports (except the wan port of the 2nd router) to connect clients.
    The only thing you have to care about is dhcp. It should only be activated on one dhcp.

    The 1st router is the gateway for the 2nd one. All clients should receive its gateways from 1st router via dhcp.

    It does not matter whether using official firmware or alchemy. The only advantage of a 3rd party firmware in this case would be the possibility to bridge the wan port of your 2nd router to the lan ports. So you have one more useable port on your 2nd router.

    Hi DevilStick

    I have another question...

    Can I manage the second router through the web?

    I tried without success, changing the port from 8080 to 8090 in second router and put port forwarding 8090---> in the first router.

    Thank in advance
