Block unsecure wifi in osx?

Anyone know how to block certain wifi networks in osx? I'm trying to block my neighbors open 'linksys' network.

Have you tried just deleting the profile?
That will restrict the system from auto-connecting to it.

Why do you care? The fact that the neighbor's net is there doesn't mean you have to use it. Or is there something wacky about Mac systems? My WinXP computer remembers to reconnect to my net and ignore all the others it sees whenever I power it up.

There's an option in the AirPort control-panel about "connect to new network". Uncheck it.

joining a remembered network works just fine, but 'hiding' a network doesn't work under 10.5.2... other networks still show up... kinda annoying, but as a previous poster stated, i just ignore it...

btw, has anyone walked through a large shopping mall lately while scanning for wifi spots? there must be dozens in one of the local malls, and a number are wide open!

(although all Apple stores offer wide-open wifi as a matter of policy)

Even here in downtown nowhere I get 5 or 6 showing up.

In areas with student housing, you will see 10+ open networks just waiting to be (ab)used.

Some people like having their wireless open... but I've never liked the concept of having anyone be able to yank out a laptop or cellphone and be sharing bandwidth on your LAN... and anything they download or attack, the owner of the IP gets the blame for. This is why I'm glad for WPA2, and 63 character random passwords that I use a USB flash drive to copy to the machines.

+1 for Boot Camp. If you have the hard disk space, its great to have, so you can play those Windows only games.

that seems to b the main selling point. Good thought...
I mainly play my wii and civilization IV. need to get the booster pack 4 it though....

By the by, the new office 08 for mac osx isn't very friendly w/other offices, especially w/word.
very frustrating @ work, where i use my mac pro (they haven't given me a computer yet) and i have to transfer documents to their windows machines.

My tech/girl says that being able to see others networks is a good thing because one can b more versatile in choices if one isn't using their own. it isn't necessary to use others networks, and they shouldn't be able to be used to hurt other networks. Also, when one goes to new locations, finding networks is easier if you don't have a wireless card/wireless usb.
thats what she told me to say.
i listened

As a response back, it should also be the option to ignore all unsecured wireless options. As a matter of security a smart household won't want their kid logging into a foreign unsecured network. Closing out all unsecured networks is the first step towards offering that kind of security.

good point. 4got that. your case in point: my teenage step sister changed the name of a neighbors network to her full name. we can't change it back, and they seem not to notice, but nevrtheless, do not want. not good @ all...

Even worse, smart neighbour captures all traffic and finds out login and password for a site not using ssl but still registered cc...information gone...its a bad scene all the way around

They introduced a new XML-based Word format and your documents are saved as .DOCM files. You always have the choice of doing a FILE->SaveAS and picking the old Word format to be compatible. This is a major problem with Office2007 on Windows as well. Installing the CompatibilityPack on the older MS-Office machines will allow them to open the new Word format.

They also got rid of Applescripting in Office08 and tried to create a whimpy form of VBA. One-button clicking to mail-merge an Excel spreadsheet into a Word-template no longer works. Now you gotta go through that annoying wizard with 15-steps and 45 mouse-clicks. Really reduced a lot of effectiveness...

Unless there's some feature that you really need in Office2007/08, why upgrade? Unless it doubles your productivity, like you can produce twice as many documents per day, or bill twice as may hours per day as before, why introduce all the hassles?

You need to do just a couple of things to prevent the kids from using the neighbors wifi, or any wifi other than your selected one(s).

1) In your Control Panel (as an Admin), select the Network Pane then click the Advanced button

2) Locate your wifi network in the list and drag it to the top of the list. Delete all others that you don't want to use.

3) Make sure the check boxes are checked: Remember joined..., Disconnect on sleep..., and Require Admin...

4) Go Back to the main panel, select your own wifi in the pull down menu and MAKE SURE THE Ask to join new networks box is checked.

5) restart (this will flush the caches)

This combination will force an Admin password to change wifi networks.

HTH

On a side note, while you can make your wifi network as secure as possible by closing it, using WPA2, limiting MAC address access to known devises, and choosing good strong passwords. That being said, wifi is inherently unsecure and tools like kismet and kismac can easily sniff out closed networks and even crack strong encription and passwords given enough traffic. WEP is a joke and can be cracked in a matter of minutes. WPA takes a bit more time and traffic, but is doable.
