    Hi, I hope this is the right place to ask and that it doesn't sound stupid, but I have a wired LAN connected through a Linksys BEFDSR41W modem/gateway and was wondering is it possible to connect a WRT54G wireless router to this setup ?
    I have tried it but it doesn't seem to work. The computers linked to the BEFDSR41W are all connected to the internet OK, but those linked to the WRT54G can talk to each other, but not to the other computers on the LAN or get online.
    I connected the internet port on the WRT54G to a LAN port on the BEFDSR41W with both configured the same way. Is this the way to do it or do I need to configure the router differently?

    should be able to with the hacked versions of firmware out i think you can turn the wrt54g in to a wireless access point im not 100% sure on this but i think it can be done maybe some one with more knowledge on this stuff can shed some lite on it :)

    Hi Shaalbon,

    Welcome to the Forum!

    This situation may be more easily solved by a stand alone Access Point (AP), BUT, you CAN use the WRT54G instead since it has a AP built-in!

    First off---

    Access the WRT54G's administration page by going to from a computer that is connected to the WRT54G by cable.

    Leave username blank and password is 'admin' unless you've changed it.

    On the Setup>Basic Setup tab we need to do the following..
    1) DISABLE the option for DHCP Server.
    2) Set the LOCAL IP Address to something that isn't going to be assigned by your other gateway such as - this way you always know how to get access to this router
    3) Save Settings

    Now - onto the Physical part of the job

    Make sure that the cable from the BEFDSR41W to the WRT54G is plugged into one of the four ports on the BEFDSR41W labelled 1-4

    Next, the other end of the cable should be connected to the 'Uplink' port of the WRT54G. It is important that it not go in the 'WAN' port.

    And there you go! the clients connected to the WRT54G before should reaquire thier TCP/IP information by restarting windows or any other method you are comfortable with.

    Hope that helps!

    Regarding the several 'hacked' firmwares available, they add multitudes of new features and do give these routers some additional features not otherwise available. These may be a bit more advanced, but bring added complexity. But for this case we're lucky that Linksys was nice enough to include the AP ability without being forced to use the router.


    For some reason, the WRT54G seems can be found for a lower price than the WAP54G, especially with the Linksys Anniversary $10 rebate.

    So - the WRT54G is a great solution when you're in need of an access point, as you'll have greater functionality if and when you need it.

    One of the advantages of the the option for 'hacked' firmware is to be able to use the WRT54G as a wireless bridge that has built in support for 4 clients.

    Hope this helps too :lol:

    For those of wondering what the BEFDSR41W is, since there is *almost* no information on it from Linksys. Here's their original press release:

    The Wireless-Ready ADSL Residential Gateway (BEFDSR41W) provides home users with their own ADSL modem, a broadband sharing router, NAT security for hacker protection, a 4-Port Switch for building the network and the ability to go wireless with a wireless-ready PC Card slot, all in one convenient box. This unique network device provides everything a household or small office needs to safely share its high-speed Internet. Users can go wireless with their Gateway when they are ready by simply sliding a wireless PC Card into the PCMCIA slot on the back of the box. The Residential Gateway then acts as an access point, allowing other 802.11b devices to connect to the network and share Internet access and resources with the Ethernet devices.

    change mode on WRT54G

    Wouldn't you need to change the routing mode from gateway to router?

    Re: change mode on WRT54G

    He may or may not have to but since it is not acting as the default gateway to the internet connection it would be best to run it in 'Router' mode.

    So, shaalbon, how's the setup working?

    James I take it that this setup could be also used in the same was with any other broadband router. I have a spare BEFSR41 v2 about here somewhere.
