    My Macbook Pro and Dell computer both connect
    to my WiFi no problem.

    So does my iPhone, iPad and iPod Touch. Problem is,
    even though both those devices accept the passcode
    and a WiFi signal is shown in the display, once you
    connect to the Internet a pop-up note comes up saying
    there is no Internet connection.

    At the same time, I can surf the net wirelessly on
    the laptops.

    Is there any reason why the WiFi works perfectly for
    my laptops but not my iPad, iPod Touch or iPhone?

    The Ivory Tower (I'm not coming down)
    What kind of wireless network (a/b/g/n) do you have? The iPhone and iPod touch require the 2.4 GHz 802.11n.

    Right now I have a Verizon Fios Adaptec
    router. I believe it is an older G router.

    The iPod, iPad and iPhone previously connected
    to it perfectly.

    However, I made some changes recently.
    I changed the passcode on the Verizon router
    to a 5 character security password so it would
    communicate with an Airport Extreme Base Station
    plugged into a powerline on another level. Basically
    the AEBS is acting as a repeater on the same
    network. It is my understanding that both routers
    will only talk to each other if the passcode is 5
    characters long. This is because of the difference
    in how both routers decode that password.

    All worked fine initially.

    Now my Macbook and Dell Laptop still connect
    and I can surf with no problem but the handheld
    devices, while able to connect to the network,
    will not acknowledge the signal they are receiving.

    I did unplug the main Verizon router and reboot.
    Did not help the situation.

    what ip's do the handhelds have? i find that sometimes my idevices pick up a strange ip not handed out by the router. it connects to the LAN, but cannot acquire a DNS address and will not connect to the internet.

    try forgetting your network on both devices and re-inputting them.

    I actually reset the networks on all three
    devices and let them reconnect.

    Still having the same problem that they
    recognize there is WiFi, display the WiFi icon,
    but when you bring up browser a message
    says there is no Internet connection.

    How ironic, I'm having the opposite problem. Want to swap?

    so do the ip's on the handhelds "match" your other devices?

    Mr Kram,

    I am at work so I can't check. Will do
    so first thing in the morning.

    If by chance they don't, what would be
    the solution?

    i forget the network, reboot, re-establish the network. it then picks up the correct ip from the router.
