Connecting Linksys BEFSR41 with Belkin F5D8230

By jrizzle77

  1. I currently am having problems with my wireless router, wehre I will keep losing signal to my laptop, so i figured I have an old linksys BEFSR41 wired router and would try to just bring the wireless router more central to the house. I was wondering if these two can even be hooked up together, and second what is the best way to go a bout it. Will I still be able to share my folders and printers through my home network? Thanks in advance!!

    Once the network flows correctly -- of course.
    Layout will be
    modem -->BEFSR41 ---->currently wired systems
                +---->F5D8230(wireless) ... portable devices
    First reconfig the BEFSR41 for a LAN address and mask
    save the config, reboot the router, and
    use ipconfig /release followed by
    a ipconfig /renew
    to get your systems internet access.
    All wired systems should be able to use the browser.

    Once that is working, config the wireless router:
    (connect a wired system to it)
    use your browser to reconfig it's LAN address to and a mask of
    save and reboot this device
    perform the
    ipconfig /release followed by
    a ipconfig /renew
    to get this system access too.

    In this Wired configuration, all systems must be able to ping each other
    from sysA, ping sysB
    from sysB, ping sysA

    all systems should be able to use the browser.

    1) change the SSID
    2) enable encryption and document your KEY

    At this point, your network is correct and you only need to setup
    print/file sharing as you see fit :)

    Now you can disconnect the wire from the F5D8230 and use it wirelessly.

    Thanks for the quick reply!!
    Had a few questions though..

    On the linksys router, you can only change the subnet mask to a few options from a drop down menu:

    And am i Just changing this on the setup page of the router? or do i need to make any changes in my tcp/ip settings or anywhere else?

    When i get to the pinging part do i just ping from the 1.1 computer and vice versa?

    Appreciate your help.

    Yea, some vendors get parochial on the settings -- any number is valid, but
    they try to over protect the user :( we need to alter the third octet to make this work

    the 192.168.*.* is a Class C, non-routable IP address. Just move your
    LAN to the Class B range, and with the
    mask of

    no -- your systems will acquire the settings via DHCP --

    I'm slowly but surely getting there. I have everything hooked up now and have internet access on all the computers and the wireless. The only problem i'm having is pinging to the wired router, and having it be accessible to the rest of the network. I can view shared folders on the wireless and wired computer through the Belkin, but won't recognize the computer attached to the linksys router. Any suggestions? You've been a great help , thanks.

    sounds like the subnet mask is wrong.

    First, what are the addresses for each router

    and what is the mask set for each on the WAN side?

    file/print shares use port 137,138 on the x.x.255 address (ie broadcast address)
    to find the systems. if the subnet mask is, your broadcast will stay
    on one subnet and not cross over to the other. using will allow the
    two routers to be seen/treated as if they were one.

    oh ok well thast the problem then .. is the subnet. I misunderstood your previous post and thought i could just change the ip address of the routers to the and and use the subnet mask. The linksys doesn't allow the subnet to be changed to, so does that mean basically won't be able to fully network all the computers?

    hum; if the Linksys controls the subnet mask EVEN for ip addresses
    172.16.x.x, then, sorry, we're dead in the water :(

    You may wish to evaluate which system connect to what, as that would provide
    connectivity but no file/print sharing (ie a form of security for wireless connections).

    The other choice is to get another router (Netgear is more user friendly), but
    sadly that means more expense.


    config the wired router, subnet mask BUT
    restrict the DHCP range to .1.10

    on the other router, get it's MAC address and use iMAC filtering on router 1
    to force to be used for the second routers MAC
    (this is almost a static assignment, but we still us DHCP).

    connect router two to router one,
    configure it to have an address of, subnet mask
    AND limit its DHCP to the range 1.30

    you will have ONE subnet 172.16.1.* with the same subnet and both routers
    will see all traffic and the broadcasting on ports 137,138

    This can be done but you'll have to make the wireless Router more a WAP and use a static IP address for it in the lower number range.

    So Linksys Router would allow the wireless access . Otherwise you could go out and buy a new wired router for $39 bucks at Best Buy like I did to solve this problem you're having. To from experience with the Linksys wired router they drop packets and connections to often. Firmware doesn't fix it something to do with the way it was made. Poorly..

    you only need MAC filtering to predict the LAN address given to the next
    router's WAN port -- been there, done it, actually running it today :)
