Cisco AP rejecting non-Cisco clients

    Hi,

    I recently upgraded the firmware (c1200-k9w7-tar.123-8.JA2) in my Cisco
    1200 and 1100 APs. Unfortunately something very odd is now happening.

    Cisco client cards (Windows), Xyxel USB (Windows), an Intel ProWireless
    3945 (Linux), a wireless PDA and an Asus wireless bridge all connect fine.

    However, any of the ten Orinoco Gold cards and an Intel ProWireless 2100
    simply do not even see the SSID. It is like there is no wireless signal
    that they can see.

    I have turned off all security and numerous times been through making sure
    all the Cisco extensions are disabled, min rate is set to 1Mb etc. - but
    these older cards just will not even see the wireless signal. There is
    nothing in the firmware release notes which is relevant either.

    I have Netstumbler running on the Intel 2100 card and it has picked up
    every wireless network in the neighbourhood but cannot see the Cisco 1200
    that is sitting underneath it!

    I have a Chinese no-brand AP which everything can see fine. It seems the
    recent Cisco firmwares have added something to make them incompatible.

    Anyone have any ideas or heard anything on these lines?

    Cheers
    NK

    As a follow up to this, I just managed to find an old download of the
    Cisco IOS from last year - c1200-k9w7-tar.123-7.JA1.tar - and have
    downgraded the AP1200 to it. Now everything works fine again.

    Clearly there is something incompatible in the latest Cisco firmwares and
    you can't get the old firmwares from their download area.

    If anyone needs the old firmware then let me know.

    Cheers

    Hm. We know of a compatibility problem between Broadcom clients and aIOS
    12.3(8)JA and above (CSCsf03190), but I'm not aware of one like this with
    the Intel 2100s or the Orinoco Gold (Agere Hermes?) adapters. It would be
    interesting to find out what the cause of this is.

    As far as getting older 12.3(7)JA based IOS - that is available for download
    from www (need to register for a CCO account if you don't have one -
    a guest level account will work.) I would recommend 12.3(7)JA5 which has
    security fixes that are missing from JA1.

    Yes - thanks Aaron that firmware works OK too.

    I am very pleased to hear that I am not alone in this! Really strange the
    way the wireless signal is completely cloaked from these other devices.

    All going well until I tried to load older firmware on the AP1100. This is
    the oldest I can download from Cisco and it won't recognise my other cards:

    c1100-k9w7-tar.123-4.JA2.tar

    So a little stuffed really. Does anyone know where I can get older
    firmware for AP1100s?

    Cheers

    If you really NEED IOS that's older than what we have on CCO, then you'd need
    to open a TAC case and get it posted for you. (The older code has security
    flaws that preclude us from making it generally available.)

    If you're looking for good old low-featured IOS for the AP1100, 12.2(15)XR2
    was pretty solid.

    Thanks Aaron. I am asking the tech guys at my supplier if they have any
    older firmware available.

    Cheers

    Intel and Cisco have had some interoperability troubles latetly. Be glad
    you're not running LWAPP/440x Controller Based wireless.

    Make sure you're running 11.1.1.0 of the Intel client. (I think that one
    supports the 2100)
