    HI,
    Hope someone can help me.
    I am trying to join two linksys routers a model BEFSR41 and a WRT54G. The hardwired router has a wan, an uplink port and 4 other ports, the wireless has an internet port and four other ports. I am currently coming out of a numbered port on the hardwired to a numbered port on the wireless and the wireless works, but I am having trouble using peer to peer on the computers coming from the hardwired router. When I investigate this I find out my IP address is 74-134-146-134.dhcp.xxxxx.com.
    I have never seen the DHCP in my IP before.
    Is there a better way to connect the two? Is it the double router causing the DHCP or is it something I need to turn off in the router?
    I am not a newbie, I know my computer but I am not exactly savvy in networking.
    Thanks ....phal

    You probably need to turn off DHCP in one of the routher, probably the wired one, in order for it to work. Basically what you need here, unless you're doing somthing strange I didn't pick up in the OP, is a routher and a switch or hub, rather than two routers. Turning off the DHCP will cause one of the routers to act as a switch and it should work.

    There's a couple of ways of going about it, but the simplest would be to follow Linksys's manual...

    If you go to the Linksys site and download the manual for the WRT54G and look at page numberd 10 (page 16 in the PDF file) it should explain what you need to do WITH Pictures.
    http://www-uk.linksys.com
    then search WRT54G and go to first hit and follow 'User Guide (PDF)' link

    The text there - there's even a few diagrams! - says this (I've added #1 = the other first router that IS connected to Internet, and #2 the second 'extra' router that you're seeking to add onto the setup):

    Hardware Installation for Connection to Another #1 Router (the non-wireless B... one)

    Before you install the #2 Wireless WRT Router, you must change the default IP address of the other #1 router. This is mandatory because both routers may be set to the same IP address by default. If you do not change the other #1 router’s default IP address, then you may not be able to set up the #2 Router.

    First, make sure the #2 Router is NOT connected to your network. Then follow these instructions:

    1. To access the other #1 router’s Web-based Utility, launch Internet Explorer or Netscape Navigator, and enter the
    other router’s default IP address, 192.168.1.1, in the Address field. Then press Enter.

    2. A password request page will appear. Leave the User Name field blank. In the Password field, enter the
    password you have set (the default password is admin). Then click the OK button.

    3. The first screen that appears will display the Setup tab. In the Network Setup section, there is a setting called
    Local IP Address, which is set to 192.168.1.1. Change this to 192.168.2.1.

    4. Click the Save Settings button to save your change, and then exit the Web-based Utility.

    5. Power down all your network devices. Now you will begin the hardware installation of #2 Router.

    6. Locate an optimum location for the #2 Router. The best place for the Router is usually at the center of your
    wireless network, with line of sight to all of your mobile stations.

    7. Fix the direction of the antennas. Try to place the Router in a position that will best cover your wireless
    network. Normally, the higher you place the antenna, the better the performance will be.

    8. Connect a standard Ethernet network cable to the #2 Router’s Internet port [ie NOT the numbered 1-4 ports]. Then, connect the other end of the Ethernet cable to one of the numbered Ethernet ports on your other #1 router [ie NOT the WAN/Internet port]

    [Then connect everything else up and power up and configure #2 as normal]

    Good luck.

    no wireless

    I followed the steps, but I have no connection to the laptop.

    I cannot access the http://192.168.1.1/ router (wireless) unless I plug directly to the desktop. I cannot access this router period unless it is the only router hooked up. I can access no routers from laptop.

    I can access the http://192.168.2.1/router (hardwired) and have connection to hardwired comps from desktops.

    I have power light on wireless router.

    I have wlan light on wireless router although manual says it should flash when active, it has never flashed.

    I have internet light on wireless.

    I show strong connection to laptop and that I am connected to my network.

    I have reinserted the passwords in both the wireless router (I hooked it directly to desktop to do so) and laptop.

    I have powered down the modem and both routers again since setup.

    Everything looks good as far as I can tell when I look at connection on laptop.

    The browser error is "The page cannot be displayed"

    Thanks...gary

    Since you mentioned the routers that you did you might have better luck upgrading the firmware to one of the many open-source projects out there. I use dd-wrt in my apt. to bridge 2 routers wirelessly. Whenever a machine hooks up to my secondary router, it gets assigned a new IP from the DHCP of the main router.

    Now this is wireless. However I would be totally shocked if there wasn't the provision to accomplish the same thing via a hardwire.

    From what I understand from the OP you aren't double routing.

    Easiest is to just disable DHCP & firewall on the 2nd one, and connect them both through the uplink port, LAN side (so uplink to a numbered port). That way Router 1 will dish out IP's to both.

    The P2P problem is probably a firewall/virtual server not working correctly

    turning off dhcp

    Hi Again,
    First of all, thanks to all for the helpful replies!
    I found out today that a friend of mine with the same internet service (cable) also has the dhcp in his IP addy.
    This means to me that the dhcp is being (issued? requested?) by the internet service.
    I turned the dhcp off in #1 router earlier and my connection to the hardwired comp was lost. I had to reset the router to get it back up again.
    I could see turning it off in router #2, but turning it off in router #1 did not work with the previous setup(previous setup = numbered port in #1 router to numbered port in #2 router).

    Also, it is normal to not see router #2 at all?

    Also, if I turn off dhcp in the wireless router, does this affect my WPA security in any way?

    Thanks...phal

    I would suggest (a) checking the Linksys firmware is upto date in both boxes (don't confuse the issue by having some undocumented software on them); (b) printing out what the WRT Linksys manual says, with pictures; (c) then doing a FACTORY RESET on the two boxes; (d) following the Linksys manual procedure for connecting up the 2 routers - its logic is right as you've inherited TWO routers, you haven't got one router and a switch.
