    Hello all and thanks in advance..

    I've burned up over 10 hrs trying to solve this puzzle and scanning through the forums. I haven't found a similar situation w a solution which is why I'm posting.

    ISP: Verizon DSL, Westell 6100 modem, Netgear RangeMax router.
    Setup works perfectly, bridged modem, Router assigns IP addresses, no worries. :)

    1st machine:
    IMac 2GHz Intel Core 2, OS 10.5.8, updated.
    Connects perfectly via ethernet and wirelessly, WPA Personal authenticat. Also works using WPA-2. :)

    WEP NOT good: asks for passphrase/key, I enter it as it is set up in the router control panel, it attempts to authenticate, then error reads "Connection Timeout."

    2nd machine:
    Old IMac PPC G4 1 GHz, OS 10.4.11.
    Connects via ethernet through both modem directly and via the router. :)

    WEP NOT good, error reads something like "failed to connect, Try Again?" I don't plan on using WEP, so I haven't looked at that setup in a while. I've been trying to set up the network as WPA. I understand there's some sort of incompatibility issue with the older Macs and WEP.

    But... WPA NOT good: similar error to above, not a timeout. My router's broadcast is detected, but this machine cannot connect to it regardless of the authentication. Does NOT work via any WPA (1 or 2) nor WEP. Basically, it doesn't connect wirelessly. It will only connect if there is NO router authentication.

    3rd machine:
    Netbook, Samsung NC10-14GB, Wireless 802.11 b/g, Win XP.
    Connects via ethernet same as others. :)

    NOT good wirelessly. It detects network/router broadcast, but does not connect to network. When I try connecting, the small window pops up saying it is attempting to connect. Eventually, the window disappears, there is no connection, there is no error notice, nothing.

    For the PC, I've attempted everything I've found online re: resetting WinSock, IP etc. via command line prompt. I've reset the router, which works fine with the 1st Mac; I've reset the modem; the software is updated, the router firmware is updated, everything is updated.

    Ideally, I'd like to get all 3 machines accessing the network wirelessly. I don't understand why the old IMac cannot access via WPA, and I especially don't understand why the new netbook can't connect.

    Any advice is truly appreciated. See command line info below:

    From Intel IMac:

    will the netbook connect with the secruity OFF completely

    I would start by getting all machines connected without WEP or WPA

    When using WEP it's always wise to use a HEX key, not an ascii passcode, because different devices can translate the passcode differently.

    The adapter/driver in the old IMac may not support WPA. If it were a PC I'd say to make sure you have the latest driver for it. If it's an external card I still suggest that. If it's an integrated adapter I don't know if Apple provides driver updates.

    Make sure that you are not using MAC Address filtering or control on the router to lock out the Netbook.

    Please connect the Netbook by ethernet plus try to connect by wireless and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following commands:

    nbtstat -n


    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Thanks for the helpful tips-- it was wise to get all the machines to access wirelessly with security totally off, per ETAF. I turned off security and made sure the Win. firewall was off.

    I also started looking through the Samsung troubleshooting info in their Flash-based manual (for the netbook). A lot of their steps referred to checking the AP, so I went back through Firefox to access the Netgear router (model WNR854T).

    In Advanced / Wireless Settings, I looked over the options and opened up the last one, WIreless Card Access List. I checked OFF the Turn Access Control On checkbox. Then the old IMac and Netbook gained wireless access. That option on the router was the culprit.

    I turned on WPA-PSK security, and all machines were able to access the router, so everything now works fine. Thanks once again.
