Can I use a Tomato router as an access point only?

    I have a Buffalo router, but I don't need a router with a firewall and NAT. I just need an access point, to connect my wireless network to my wired network. Is that possible?

    Yes, and setting it up will depend upon how the rest of your network operates. What device gives out dhcp, is the wireless device just going to be used as a router and not a gateway? Etc, all you would have to do is turn off the firewall and take it out of gateway mode, but there are many ways to go about doing what you are trying to do.

    Go to the settings page "Basic: Network"
    and disable WAN and the DHCP server.

    Will it use the DHCP client to get an IP address from the local network instead of the WAN in that case? I can't seem to find any documentation of that behavior.

    no, it won't (AFAIK)

    Like what has been previously mentioned you need to do the following to use it as an AP only.

    Apply on AP device
    1) Disable the dhcp server service on the AP
    2) Set the default gateway and primary dns addresses to the IP addresss of your wired network router
    3) Plug in the AP to you wired network using one of the LAN ports (WAN won't work)

    That should be all you need aside from setting the AP wireless options to the desired security scheme.

    For AP only, you can even skip step 2 completely if it is getting too complicated for you. To re-complicate matters for you, disable WAN in the Basic screen and set wireless mode to "Access Point". Are you actually waiting for days at a time to get instructions from a help forum when 10 minutes of fiddling with the settings would answer yer questions ?

    Actually I have done some fiddling already, but if I understand correctly there is no provision for a DHCP client on the LAN, only on the WAN, so I would have to use a static IP on the AP. So let's call this a feature request: I would like to see a simple AP setup that doesn't require a static IP.

    Dude, forgive my being rude, but you've seriously got your head up yer ass. If you had tried the configuration advice that has already been given you, you would have already found this out. In access point mode, with the WAN port disabled, the access point will directly bridge the wireless part of the device to the 4-port wired part of the device, allowing wireless clients to obtain an address from the DHCP server that you already have on the LAN. You are not required to use static IP on your client devices. This is a very fundamental functionality of any access point, and you are foaming all over yourself about static Ip and new features and stuff. If you really want service, just hook the damned thing up and set it like you have been instructed to do. To your amazement, it will work great. The WAN port has a DHCP client for itself in router mode. You are using access point mode with the WAN turned off, so the WAN client has nothing to do with anything. The router has a DHCP server that servz addresses when in router mode. Again, you are not using router mode, so this is also irrelevent.

    FYI:
    The IP address of an accesspoint is not required to be in the
    subnet of your local network, even so this is 1) common and
    2) useful. Choose whatever static IP you want, as long as it
    does not clash with any other IP in your local network.

    Sorry for being a Network Newbie. I understand that DHCP requests from wireless clients will be forwarded by the AP to the DHCP server on the LAN. I was only wondering about the IP address for the AP itself. If I understand Odin-60 correctly, I will have to set it to a static IP if I want to be able to access the HTTP server on the device while it is in use. So all I was asking is that the firmware developers consider adding a DHCP client option on the LAN side when the DHCP server is disabled. Not a huge deal, especially since DHCP client code is already in the firmware. Thanks for all your help.

    If it were to be given the ability to obtain an Ip address by DHCP, you could still access the HTTP server on the device. In this case, you would open your web-browser and enter the IP address of the lowest IP in your DHCP range. If that was not the address that the AP had obtained, you would simply increment the address in the browser bar by a value of one, and continue this process until you are able to locate the proper address of the AP. You would want to limit the range of the DHCP server to as few addresses as you really needed for your network so as to reduce the hunt and search time as much as possible by giving the AP as few places to hide as possible. I would have never fathomed that this was your objective. Maybe Jon (the author) will help you out on this. There is a "Wish List" thread in here somewhere. Maybe you should drop a post in there.

    AP on the same network?

    somewhat inline with the same question: After doing the basic setup to use my WRT54GL as an AP I'm able to access the internet but unable to access other computers on the LAN. I'm guessing its because the router IPs are different. I've followed these steps:

    1) Disable the dhcp server service on the AP
    2) Set the default gateway and primary dns addresses to the IP addresss of your wired network router
    3) Plug in the AP to you wired network using one of the LAN ports (WAN won't work)

    However, the IP address for the AP is 192.168.1.1 and my primary router address is 192.168.0.1. I've tried changing the AP address to something else (192.168.0.2 or 192.168.0.50) with no luck...I'm unable to access the AP after the change and have to reset it.

    Any suggestions?

    Easiest way--> there's a switch on the bottom of Buffalo Units to switch between AP and Router Modes. Not sure if Tomato takes advantage of this switch. Good Luck!

    Thanks but I'm using a Linksys WRT54GL.

    All of your devices need to be in the same subnet. If you say that after you change the IP of the AP you can't access it, that probably means you need to change the IP of your PC to the same subnet as the AP, and your primary gateway. i.e. 192.168.0.x

    It would seem most logical to change the AP IP address to match the routers. If I change the computers IP to match the AP, I still wont be able to see other computers on the routers network.

    What is your "subnet mask" on the AP and on the primary router?
     
  19. freee

    freee LI Guru Member

    Subnet mask on the primary router is: 255.255.255.0
    Subnet mask on the AP is: 255.255.255.0

    ...Do the primary router and AP need to be the same router brand or same models to work together?

    I am trying to use my Asus Wl-500gP v2 Router as a simple access point so that my WiFi laptop and phone can access my wired LAN, but I am having no luck.

    I am running Tomato Firmware v1.28.9052 MIPSR1-beta23 K26 USB vpn3.6 (Teddy Bear's build).

    On my wired LAN, I have my main router that is the DHCP server and the Internet gateway.

    Wireless devices, like my HTC Desire smartphone, can see the Asus router, but when they try to obtain an address, the DHCP request is not being passed onto the wired LAN and does not reach my main router

    When I allocate a static address to the HTC Desire, I can access the Tomato Admin interface on the router, but I cannot access any machines on my LAN. Even ping fails.

    If I SSH into the router itself and run ping from the Linux command line, I can access both the wired LAN and wireless devices.

    I have tried the following:

    1. In tomato admin, disabling the WAN port, and connecting the wired LAN's etheernet cable to one of the other ports of the Asus router.
    2. In tomato admin, setting the LAN default gateway to 192.168.0.1 (The IP address of my main router on my wired LAN).
    3. Disabling the DHCP server on the Asus router
    4. Setting the router to "Router Mode" instead of the default "Gateway" mode.

    Despite this, it still doesn't work. Has anyone else had this same problem?

    I really do need wireless network access, so I have temporarily configured the Asus router to work as a normal NAT gateway, i.e. the Wired LAN is connected to the WAN port, and wireless devices are being allocated a second private network address.

    This is not a long-term solution, as I need all devices on my LAN to be able to directly communicate with each other via their allocated IP addresses.

    IP address of ASUS router??

    Actually, that's how I use Tomato also. I've never used it as a normal router.


     
  23. vlad_oz

    vlad_oz Networkin' Nut Member

    Thanks for your reply.

    The main router is 192.168.0.1. My Asus router is 192.168.0.2. The subnet is the standard
    Class C subnet, 255.255.255.0.

    Well, the way you phrase things sounds like you know what you are doing.

    So, other than the obvious ASUS IP address, I'm not sure what help I can be other than a few suggestions:

    1) You didn't answer #4 (router mode vs. gateway). I've only seen this option on Linksys standard firmware, so I don't where this is coming from (something from Teddy Bears build or part of ASUS firmware?)

    2) Did you try a wired client into the ASUS? (try and determine a generic problem vs. a wired/wireless problem).

    3) Did you do a complete NVRAM erase and configure from scratch after loading Teddy Bears mod. This is *highly* recommended to do this (some might say mandatory).

    4) I've never used Teddy Bears mod(s). I've only only used standard Tomato and Victek's RAF mods. Victek's mods have been very good for me, especially the latest 1.28 builds. I use 1.28 K24 lite for my WRT54G v4 and WRT54GS v4.

    I am using my Linksys WRT54G with Tomato v.1.25 as an access point & a Thomson TG784 as my router, I still want to use my access restrictions on the WRT54G as it is more flexable than the Thomson but it does not seem to be working. The most important thing for me is to be able to use Tomato access restrictions.

    Access restrictions apply to the device managing the WAN connection only. A router using Tomato in AP-only mode cannot apply access restrictions.

    Thanks Rodney, can I use the wireless mode changing it to wireless client or wireless ethernet bridge to use the access restrictions?
