    Please help.

    I bought an airport extreme 4 days ago and only have a week left to return it if I cannot get it working.

    I have verizon fios 25/25 speed. I have an ipad 3, iphone 4, 2 windows 7 laptops and 1 windows vista desktop.

    I have tried to install the airport extreme so that I can get a faster wifi signal and more importantly a longer distance of wifi range than my verizon router.

    Presently, I don't think the extreme is working as everytime I connect to it from laptop, iphone or ipad I don't get internet.

    Unfortunately, I have no clue as to how to answer the prompts when I use the airport utility program on my windows 7 laptop.

    So I tried to reset factory defaults.

    first question
    1a I want to create a new wireless network
    1b I want to replace an existing base station or wireless router
    1c I want aiport extreme to join my current network

    I think I want a

    second question
    2a Bridge mode
    2b Share a single IP address using DHCP and NAT?

    I have no idea

    I chose 2b

    question 3
    Then select how you connect to internet
    3a i use a dsl or cable modem with a static IP address or DHCP
    3b I use a dsl or cable model using PPP over Ethernet (PPPoE)
    3c I connect to my local network (LAN)
    3d I am not ready to connect to Internet right now

    If I select 3a or 3c then it asks me for dns server, etc?
    Do I really need that?

    then it restarts
    problem 1 of 2 your apple wifi base station doesn't have a valid ip address

    I have no idea what to do.

    I think I'm stuck.

    Please help I only have a few days left to return this if I can't figure it out.

    Here is the deal... the modem Verizon provided has a built in router and you are trying to connect another router behind it. This can cause what is referred to as "double NAT" and the problems you are seeing. You can work around it by setting up your Airport Extreme in "bridge mode".

    So here is what you want:

    1a I want to create a new wireless network
    2a Bridge mode
    3a i use a dsl or cable modem with a static IP address or DHCP

    You should be able to leave DNS blank and it be assigned the Verizon DNS servers by the Verizon device. Or you can use the OpenDNS servers at and

    This should fix you up.

    I had 2 errors but used and to fix one error.

    Then I switched the fios router ethernet cable from it's WAN jack to the LAN jack and then it worked.

    I really appreciate all of the help.

    I think I'm in business.
