Problem in setting a primary router

    I am a newbie on routers, so sorry for this basic question. I'm setting up my router (Netgear WNR3500Lv2) with TomatoUSB as a wireless router. The setup for wireless is as follows on the Tomato web interface:

    Enable wireless: checked
    Wireless mode: access point
    Wireless network mode: Auto
    SSID broadcast: checked

    Security: WPA2 personal
    Encryption: TKIP/AES

    The Netgear is broadcasting signal and I have no problem getting access to the router's web interface either wirelessly or through an ethernet cable, but the problem is the Internet connection is not working with my modem!

    I have a backup router (Belkin with stock firmware) that has no problem with internet service with my modem. So what could be the reason for the internet failure with my Netgear? IP or Mac address conflict with the modem?

    I can even ssh to the Netgear on the terminal:

    ssh root@

    Is there a way to diagnose the problem?

    I basically followed the instructions for wireless here:

    and used these steps for router setting:

    Any help would be highly appreciated!

    pls review the belkin's wan parameters ( dhcp, fixed, PPPoE ? ).
    try switching off both the modem and the router. then power on the modem, and when it as fully booted up power on the router.
    if this doesn't work, clone the belkin's wan mac address in the netgear ( advanced, mac address, wanport ) and repeat the same sequence.
    look in the tomato log ( status, log, if necessary configure it first ). are there wan related entries?

    Thank you so much for the help, PetervdM!

    Yes, right after I cloned the Belkin's Mac address and then performed power-off-and-on, the internet connection is now working properly on the Netgear router! Does it mean that my modem only recognizes my Belkin, but not the Netgear? How to fix this?

    When I clicked "View All" under Status/Logs, I saw a long list of records. Sorry I don't know what to look for. Could you explain what kind of entries are WAN-related?

    Thank you again for your kind help!

    Your ISP recognizes the MAC address that was originally used, i.e. the Belkin - it is the address they have stored in their computers for your account. So you trick them into recognizing the new Netgear by using the MAC address of the old Belkin.

    Now your ISP thinks it is still talking to the Belkin router, problem solved.

    Wow, I never realized that the ISP could have caused the grief! I was frustrated by this for two full days, and had been thinking of my router setup steps or the modem that was the culprit...

    I switched routers a few times before, and don't remember that I had similar issues... This is a security feature from the ISP? I guess I would have to use this trick from now on...

    I'd like to take this opportunity to thank you Toastman for explaining to me about this and, more importantly, for your generosity to share the wonderful work!

    P.S. after some googling, I understand my problem much better now. A lot of new stuff for me to learn...

    Well, I wouldn't say it's so much a security feature than the way the ISP works. Their systems use the MAC address of the modem to recognize it is online, to access it and set it up. Usually they supply cable modems free of charge, that makes it easy for them. But when you buy one of your own, most support staff working for ISP's have not the slightest idea what to do - this wasn't covered in their training :eek: Rather than spend several weeks trying to find someone who will put your MAC on their system, it's just easier to clone the old one.
