When getting online Macbook defaults to an unknown network.

Lately, when I get online, my connection defaults to an unknown network. This happens only on the Macbook, other devices are OK. Is there any way to lock the computer into just my own nework? Could not find anything in preferences.

Please try the following on your MacBook:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.

Can I get my macbook on to a windows network?

Hi, I was wondering if i could use my mid 2009 macbook on my dads windows 7 home network. He has the network already set up, and has enabled printer sharing and some of the other options. I wanted to know because it would be very handy if i could print documents and other various items from my macbook, without putting it on a usb drive and crossing it over, and my dad does not like me using his computer very much .
Thanks, Travis

13017 Received TACACS+ packet from unknown Network Device or AAA Client

I am adding new routers to our Corporate network for a new MPLS network. I am getting 13017 Received TACACS+ packet from unknown Network Device or AAA Client errors for these new routers. They are added to ACS 5.4.0.30 correctly just like all of our other devices. We have never had real routers on the network before, just switches and access points. Is there something special I need to set in ACS for these to work and authenticate correctly? I can only access the currently with built in login locally.

Open System Preferences > Network > Advanced, and see if your network appears in Preferred Networks. If not, do it

How do I get my Macbook Pro to fill my name, address , state automatically when i fill in a form? It use to do it.

How do I get my Macbook Pro to fill in my name, address, city, state and zip automatically when I start to fill out and online form? It use to do it, all I did was put in the first few letters of my name and hit the tab button. Now it no longer does that for me.

The free MPEG Streamclip and the free component from http://perian.org can convert your AVI to a format understood by iMovie.

When I try to get online, my computer reboots. I had to uninstall Firefox 5 and go back to Internet Explorer.

I had to update some drivers. After doing that, every time I try to get online with Firefox 5, the computer automatically reboots. I had to uninstall it.

I see. Well, I just tried to make IE my default browser, but it did not solve the problem. I receive the same script error when I view the image. (I may not have explained this thoroughly enough at first - I do get to view the image after answering the error message, but the print button embedded in the window doesn't work. Before, I never had a problem with viewing or printing.)
I imagine that at this point I will either need to communicate this to the IE people, or possibly revert to an older version of IE.

When I try to open video files purchased through iTunes in Quicktime, I get the message: 'Error 23132: an unknown error occurred. This never happened until I updated iTunes, but when I try to go back to the previous version, I still get the message.

When I try to open video files purchased through iTunes in Quicktime, I get the message: 'Error 23132: an unknown error occurred. This never happened until I updated iTunes, but when I try to go back to the previous version, I still get the message. It is more convenient for me to play videos in Quicktime since iTunes is such a memory hog. Please help.

You may get better results if you switch to this alternate version: iTunes for Windows (64-bit - for older video cards) and, if needed, reinstall QuickTime. The new (nearly) all 64-bit version doesn't seem to play well with QuickTime. Perhaps if DRM authentication is required QuickTime needs to be able to see something that is part of the older 32-bit code.

How do I get my Macbook Pro to automatically select the location when connecting to the wireless network?

Each time when I want to connect to a different network I have to manually select the location and it's becoming very annoying. How do I get it to automatically select the location?

Check the following settings on your MacBook
Open System Preferences (gear icon on the dock)
Open Network
Click on AirPort on the left
Click Advanced at the lower right
If you have a "favorite" network, make sure it is first in the connection list. If it's not, drag it there
Make sure that there is a check mark next to "Remember networks this computer has joined"
No other boxes should be checked
Click OK, then click Apply

Just upgraded to latest iTunes for Windows. Rebooted the PC as required. When I bring up iTunes I get a pop message saying "An unknown error occured (-42110)". What does that mean?

How do I fix it?
Thanks!

Removing the SC Info folder as per the "Error 3001," "-42110," or "5103" section in the Specific Conditions and Alert Messages: (Mac OS X / Windows) section of the following document seems to help most folks reporting the iTunes launch 42110s:

Hi,
Also try turning Off Face Time
Open Face Time
Go to the Preferences
Set it to Off.
Also make sure your router has the Time and Date/Time Zone set as this upsets Face Time which in turn upsets IChat

Having a problem out of nowhere really getting this MacBook back online through Ethernet.....it's not the modem because my old computer gets online as well as the ps3.....I think it has something to do in network diagnostics but I can't get it.
Thanks!

hi there-
to determine which network port is being used go to the blue apple > system preferences > network and then on the show scroll menu select "network port configurations". then make sure the card is detected there, select it, and then deselect any unused network ports. (the rest of them). [ 8 ) ]
