Cisco AP1200 problems! All clients looses ip.

Discussion in 'Cisco' started by dcNOSPAM@sandmark.se, Apr 11, 2006.

    Hello,

    We have a Cisco AP1200 network with 12 AP's and 15 klients roaming
    between them.
    The problem is that all 15 clients (cisco 350 cards) looses ip after 30
    - 40 mins.

    Clients need to be restarted in order to get the system back up.
    I have no idea where to start troubleshooting. The network works fine
    with only 4 clients up and running, roaming is ok and everything.

    I will post my AP logs. I hope there is someone with more cisco
    knowledge that can help me out and guide me in the right direction.
    Thank you in advance!

    So I should update to the latest available AP1200 firmware?
    Anyone know which version thos latest firmware is, and where to find
    it?
    The cisco site is not very userfriendly :(
    Thanks

    Upgraded to 12.3.7.JA3, still locking the network if I run more than 5
    clients.
    All my clients use the same user/pass auth. the networks windows 2003
    server.
    Can this cause the problem? Maybe this is not a cisco issue?

    Any advice?

    Ignore the part of the same user/pass... We do not do any auth. against
    w2003 server. Only auth that is done is against the AP using WPA...
    Still welcome any advice!

    Hi!

    I have all my logs available at http://www.sandmark.se/ciscohelp/
    I would appriciate any possible guidelines :)

    I have removed the first 2 ip fields for security reason since they can
    be reached over the internet. first two fields is replaced with *.*

    Thank you

    It appears that you are using basic 802.11F roaming (IAPP)

    Questions
    1. Are all of the APs on the same IP subnet ?

    2. What client software version is being used with the 350 wireless
    cards ?

    3. Does the problem occur as soon as the 6th client associates or 30 to
    40 minutes after the 6th client associates and every 30 to 40 minutes
    after that?

    You might want to see if configuring "dot11 network-map" provides you
    any useful info via the "show dot11 network-map" command

    Do you have two wireless workstations that have the same MAC address ?
