    ... and now my laptop doesn't realise it has wireless capabilities.

    And when I open my Network in System Preferences, "Network settings have been changed by another application" pops up and every time I click Ok, it pops up again, not letting me be able to access any other option in the Network window.

    The wireless icon has disappeared from my top bar and the only way I have managed to get online is via my ethernet cable.

    I have had nothing but problems since I started using my O2 Wireless Broadband dongle and I've noticed that behind the "Network settings have been changed by another application" notification, I can seen the Dongle has appeared as a new network connection option... but was never there before today (have been using the dongle for two months now)

    Any ideas?

    Delete the following file to solve the not getting into "Network System Preferences":
    preferences.plist under Library/Preferences/System Configuration/.


    That will reset all your network locations, and the annoying message will disappear.

    Open Security prefs pane... make sure "Require password to unlock..." is checked. That will resolve the pop-up issue. Once its resolved, delete your unneeded locations.
