    This weird thing has just started to happen.
    My wireless has been working fine for about a year.
    Yesterday my connection dropped for no reason.
    I tried to connect again with my password, but it says 'invalid password' and won't connect.
    If I restart my mac it connects without any password request.
    Can't figure it out.
    Looked into network settings, but if my mac is connecting on start up, then it still has the password, so I don't want to change too much. This also means the router is ok, no?

    The router is a Thomson TG585 v8
    Co-op internet.
    Macbook Pro 2.4Gz Intel Core 2 Duo
    4Gb 1067 MHz DDR3
    OS 10.6.7

    Sounds like during the connection drop, the router is failing to decipher the encryption. Been a while since I knew all the theory behind this but it might be worth recycling (ie. switching off and restarting after say 20 secs) the router if you haven't done so already. I've had the same problem previously and my thoughts are that it isn't your MBP's at fault here but I might be wrong.

    Two things you can try:

    1. Remove/delete .plists associated with network and AirPort.
    2. Repair/reset your keychain.

    You could also try to create a new user and see if the problems happens there.

    To remove your .plists:

    1. Turn off AirPort
    2. Go to Macintosh HD>Library>Preferences>SystemConfiguration
    3. Move com.apple.airport.preferences.plist and preferences.plist to the desktop
    4. Restart computer

    Yay!

    Thanks Big Jobby!
    Problem solved.
    I had pressed the reset button before, but didn't know about turning it off for 20secs.
    What a relief!
    Nice Big Jobby.
    :)

    oh dear!

    It's happening again.
    Perhaps it was a false start!?

    I have tried the following things;

    1. Deleting the com.apple.airport.preferences.plist and preferences.plist (in MacintoshHD/Library/Preferences/SystemConfiguration)

    restarted.

    2. Turning off the router for 30sec

    3. A combination of both things

    4. setting up a new user and using that account

    none of this seems to solve the problem.

    bizarre.
    My iPhone isn't having any of these problems, but my friend tried to log on with his and couldn't. It said the password was wrong.

    Can there be gremlins?

    Interestingly, my 2011 started doing this same thing a week or so ago... right after an update from Apple. Did you do any updates recently?

    mmm

    It's hard to know,
    I sort of do the updates like I hitch up my trousers; I don't really notice myself doing it.
