Question

Mac Network Lock unlocks itself!

Jul 6, 2012 8:15PM PDT

My Mac OSX 10.5 is connected to the Net wirelessly via an Apple Airport Express, with the Network Preferences lock ON.
But after restarting after overnight shut down, the Lock Is OPEN and the network has reverted to the provider's default, in this case "Fon Zon Free Internet" (not free!)
How is the lock being unlocked ??

Clarification Request
not sure what is causing this but,

what do you mean by "providers default"?

What do you have it set for when you lock it?

Have you ever been back to the Network Preferences after you have locked it but before you shut down for the night?

Can't Lock Network Choice
Jul 7, 2012 2:37AM PDT

The network provider is Zon Portugal. The network list in order of preference show's my name i.e JB's Network as 1st choice at the top - LOCKED!
Below that is "Fon Zon Free Internet", then "Zon-3F90". I've tried to delete 2nd and 3rd from the list, but it doesn't appear possible. Hence my use of the word "default".
As long as the computer is running, there's no problem. But recently - to start the day on max free memory - I've been shutting down overnight.
In the morning, or whenever I shut down, networks preferences appears UNLOCKED and the 2nd UNWANTED network is selected. (This effectively means NO internet connection). So it has to be re-set by me in Networks Preferences when I - or any 3rd party - want to go online. Any idea how come the lock UNLOCKS if not authorised by the administrator (me)?

Go to System Preferences,

Network,
WiFi,
Advanced.

There you will see a list of wireless networks that are stored in your machine.
Select the one(s) that you do not want then hit the "-" (Minus) button
Do them one at a time until you have the one you want as the only remaining network

Now put a check mark in the "Require administrator authorization to: Change Networks line.


Give that a whirl

Woohoo!

Woohoo! Thanks! It worked, though only after re-typing "Apple Network 9aa 2bft" below my "JB's Network" in Advanced.
The only (minor) irritant now on re-booting is reversion to unnecessary maximum screen brightness, which I can't seem to override, so always manually reset to minimum.
Thanks again.
