    Have a wi-fi, only one device is affected:
    MacBook with 10.5.8

    Upgraded to 10.6.3 to no avail.

    Network connection panel say connected but no browser can access a url.

    Happens only after sleep, and not always.

    Only a re-start works for getting connected again.

    Tried resetting keychain. Tried deleting 'Preferred Networks'

    Any thoughts appreciated.

    Try disabling the security on your router TEMPORARILY and see then if you have
    issues. This will help eliminate whether it's a router security issue.

    Ok will do.

    Our iPad, iPhones and 2 other Macs do not seem to be affected.

    Tried for a couple of days. Does not seem to have helped.

    I should add that when I wake the MacBook it often connects for awhile before the disconnect. Shows connected & the IP address but can not open any page regardless of the browser.

    I have had this problem from time-to-time. Instead of rebooting I typically turn the mac's wifi off, then back on. That usually gets it reconnected.

    Thanks for the tip however I have tried signing out then back in (same user) and tried turning off the Airport then back on, tried repairing permissions. The dis-connect seem to generall happen awhile after sleep and when I have several web pages open.

    Presently the DNS server is set to the mi-fi cellular wireless lan:
    192.168.1.1 / lan

    So changing to 8.8.8.8 is not a problem?
    Remember this dis-connect is only occasional, see OP.

    Perfectly safe and this configuration change will not interfere without the operation
    of your Mac.

    (You can always change it back if you want)

    Tried it, sadly no help. Seems to be MacBook problem judging from other threads.
