    Hello everyone,

    I have a small network here in my home and I would really like to receive some hints on how it could be better configured.

    This is its current configuration:


    How can it be improved?

    As being new to wireless networking, I've set up my WRT54G as a default router configuration. This works fine for browsing internet through my wireless devices and also I can access my network shares on my computers. It just becomes a problem when I try to access network shares on my notebook from another computer and also I can only manage my WRT54G form either my notebook or changing PC3 to one of the LAN ports on my Linksys.

    Thanks for any help you guys are able to give me!

    Change the WRT54G IP address to so it is in the same subnet as the rest of the network, then instead of using the WAN port on the WRT use a LAN port.

    Hmm... great idea Toxic, thanks for your help!

    Should I will also disable my 3Com DHCP server to avoid conflicts, right?

    Then my WRT54G will provide DHCP info for all wired or wireless clients, am I right assuming this?

    yeah only have 1 DHCP server running either the 3Com or WRT can do it. doesn't matter tbh. just make sure the 3Com and WRT ip addresses are not in the range given by the DHCP server to stop any IP address conflicts.

    Hi Kibe,
    Offcource using Router as a wireless switch is the best thing that u can do for ur network as suggested by toxic,but what i would suggest is use dhcp of ur 3 com not on ur linksys because u are using that as a wireless switch....

    I also generally want to stay away from having a double NAT'd network..generally you only want 1x router on your network. If you already have a router..and you want to add wireless...add an access point, or get a wireless router that supports being flipped to an access point.

    To keep things simple, you want to have your router that connects to your ISP run the DHCP..this way any DNS changes the ISP makes are quickly updated on your end without your intervention when internet resolution stops one day.

    Now....many times the wireless router you have..which you'd normally flip to an access far superior to the combo modem/router unit that your ISP gives you. In those cases...I flip the combo unit to "bridged mode"..making it just a plain modem..and use my router for the PPPoE/NAT/Routing/DHCP/etc etc.
