"Allow this network to be extended" has disappeared from latest Airport Utility
I bought the new Airport Timecapsule (the vertical one) and have the latest version of the Airport Utility. Under "Create a wirless netwrk" there used to be a checkbox that said "Allow this network to be extended" As best I can tell, that option no longer exists (at least with the latest Airport Timecapsule). How does one extend this network? I have been using another Airport to extend my network and would like to continue extending it.
"Allow this network to be extended" is automatically enabled (and hidden) in the newer versions of AirPort Utility 6.x, so there is no setting needed for this.
The setup to "extend" is now much easier to configure with AirPort Utility 6.x compared to previous versions of AirPort Utility.
What device will you be using to "extend" the network? Do you plan to "extend" wirelessly, or "extend" by connecting the AirPort to the Time Capsule with an Ethernet cable? (Much better performance with the wired connection if you are able).

The current KB article about extending wireless networks is out of date--how do you "allow this network to be extended" on AirPort Utility 6.x? These instructions describe v. 5.x.
In my case, the option was required, so the problem was that it wasn't available. When I used v6.2 to extend the network on the secondary AP Express, it gave an error saying the network couldn't be extended.
Once I booted Snow Leopard from an external drive, I was able to follow the instructions in HT4259 with v5. Once I checked the "allow this network to be extended" on the primary AP Express, the secondary AP Express started extending the network as it should.
While v5 of the AirPort Utility is available for download, it won't work on Mountain Lion, so this solution wouldn't work for most people, who don't keep old operating systems lying around. -
Quesion regarding "allow this network to be extended"
All,
Please excuse my dumb question. checking the box marked "allow this network to be extended" is a setting only used when adding another Airport router and will not increase range otherwise?
sorry to sound dumb, just trying to educate myself.Bob,
Thanks so much for your help. I had read through info that lead me to believe that, but I needed the plain plain english version. sorry.
Can I pester you on another question?
As I am newish to the airport extreme (802.11n) we have an imac, hp pavilion, wii w/ netflix streaming account, and use radio apps on our blackberries. If i increase the multicast rates will this help or hurt? Conceptually I am hoping it will increase speed to netflix. but it could cause problems right? -
Should I ok this message-this computer's local hostname Irma's Mac-mini-local is already in use on this network. The name has been changed to Irma's Mac-mini-2local
Don't think this is a conflict with IP Addresses or computer names
= DHCP hangover when computer renews DHCP lease
There is no actual other computer
It just appears that way when reconnects so creates new -2 computer name
What types of names do you use your computers ?
Whether you name them after quantum particles or the romantic poets...
They will each start to be appended with "-2" then "-3" etc if you auto configure network settings from Airport Router DHCP service and you have this Change computer name issue where pop up window states name is already being used on your LAN
As stated previous post you can reset the computer name in SysPrefs / Sharing / Edit button
And restart Router or renew all DHCP leases (if persists in not allowing original name)
Can now press Edit and reset name of choice
But for Fix see link above -
Can't locate email content? All of a sudden my email content has disappeared from inside MacMail? The actual emails are coming through but I am unable to view them in the content area! Nothing has been done to have changed this?
Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2. -

The volume control has disappeared from the music app on my iPhone and i can't play any music how do i fix this?
Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps from the tray BEFORE doing the reset.

I recently got a message with an exclamation mark stating "your computer name is already in use on this network. The name has been changed to ______"
How did this happen, is it phishing, malware, or did someone hit some button on here to change it. I'm hoping that someone else doesn't have access to everything on my computer now. Help!Hello RaptorTrish,
Interesting name! You don't say what computer you are using, the OS or the nature of the network, home, office etc. Could you fill in a few details.
You are right to be concerned but there is often a simple explanation. -
Error after 10.7.4 Lion Upgrade to iMac
Computer's local host name .......is already in use on this network. the name has been changed to........
and it keeps adding up the number each time I wake the iMac.
What to do to get it back before upgrade error?Ok worth repeating, hope this works. Finally spoke to AppleCare Support and walked me thru following...restart computer holding down "command" and "option" keys at the same time with letters "P" and "R" when computer turns on. This is what he called a PR restart, clears out discrepancies in memory (if that is what the error message actually is). Then went to Systems Preferences/Network/Sharing and deleted the number that kept increasing every time MAC would wake up.
Even tho this was just done, I am hopeful that error pop-up won't happen again. Fingers crossed! -
error message that my local host name is in use and the system generates a new one every time I wake my mac the error mssg reads This computer’s local hostname “D-360.local” is already in use on this network. The name has been changed to “D-444.local”.
There are several possible causes for this behavior.
1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.
2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models.
4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

What does this mean: This computer’s local hostname “Linda-Daviss-iMac-4.local” is already in use on this network. The name has been changed to “Linda-Daviss-iMac-5.local”.
When I came back to my computer this message was on the screen. Should I be concerned ? or doing something?Sometimes this message means that you have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. Disconnect the Ethernet cable or turn off Wi-Fi.
Sometimes it happens because a device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
Rename the computer in the Sharing preference pane. -
I get this message: This computer’s local hostname “x-8.local” is already in use on this network. The name has been changed to “x-9.local” I have turned off sharing and it continues to upgrade name. What is the fix?
Hi, this is a common problem, mostly just irksome though.
It can have many cause, like using more than one Interface for connections, Router temporarily losing x.local & seeing a new connection with x.local already used, insists it must be x-1.local, x-2.local, etc..
What all Sharing do you have enabled?
Some possible fixes...
