Mac Pro Lion & Default Connect To 5Ghz Airport Extreme

Hi there
I just got an Airport Extreme last week, setting it up to have a dedicated 5Ghz network as well as the 2.4Ghz one...
My Mac Pro is set up to only remember the 5Ghz, to ask me to join new network and not to remember networks I join... it's also configured to require admin password to change networks... all of this is done in an effort to prevent it from joining the 2.4Ghz network, yet it still does sometimes when I reboot my Mac or the base station itself...
In addition, despite having 'Remember Networks' de-selected, it still remembers the 2.4Ghz...
Any ideas?
Thanks!

So I should name the '5Ghz network name' as the exact name as my 2.4Ghz network?
As a test, yes. That is also Apple's recommended default setting for the AirPort Extreme....designed to deliver the best performance for most users. Devices automatically choose the best connection quality this way.
It actually seems that you can't do this... going under 'Wireless Options' and trying to name the 5Ghz network with the same SSID as the 2.4Ghz results in it renaming itself after the update to the default Apple specifies (i.e, 2.4Ghz name 5Ghz)...

"n" devices operate on both the 2.4 GHz and 5 GHz bands. Not sure what you mean by "separating" them. Some "n" 2.4 GHz devices cannot connect to 5 GHz, so you would want them to connect to "n" speeds on 2.4 GHz.
If you find 5 GHz faster at all Mac locations, then you'll have to continue to look for a way to insure that the Mac always connects to 5 GHz. As it stands, it appears that the Mac "thinks" that 2.4 GHz may be the better connection, and it may need some convincing to think otherwise.
That's true, but my understanding (and experience) is that if you connect any 'g' or 'b' devices to the 2.4Ghz network, any 'n' device will have its performance degraded... for instance, in my case, when connected to the 2.4Ghz, my Finder copies were around 3MB/s - on the 5Ghz, they were closer to 6MB/s
I thought that the preferred networks order was to specify preference, regardless of network strength... I guess not, though... although, maybe something is amiss because I do have it configured to require a password when changing networks and it doesn't do that at all... even when I change them manually...

My macbook pro won't connect to my airport extreme

OOPS...it actually says "Incompatible security". Any ideas? I had no problems connecting to my other wireless network at home.

IMac Won't Connect to 5ghz Airport Extreme?

Hi,
Brought home a new 17" iMac (2.0, 1G Ram, Superdrive) and an Airport Extreme. I set up two networks, one for iMac and my wife's Macbook to run on the 802.11n (5ghz) of the Extreme, and the other a "g" network for the older laptops. I set this up by using the "secret" published in this month's Macworld. Turns out my iMac won't run (or even see) the 5ghz "n" network, but does see the 2.4ghz "n" network. It seems speedy enough at 2.4 but I'd like it work with 5ghz. Apple's site says the 1.83ghz iMac won't do this but that's it--I assume the 2.0ghz version will. Any help is appreciated.
Joe

Thanks for your reply. Yes, I did run that disk. I followed the instructions on the Apple site to check the Network Info utility to make sure the "n" appeared for the airport. Not sure what to do next. My wife's Macbook (which we also purchased yesterday--we made Steve very happy!) sits about four feet from my iMac and works just fine on the 5ghz band. Strange.

Default Connection on startup - airport extreme

When i start up my mac it no longer auto connects to my wireless connection. I have to tick it manually everytime and its really annoying....
Any ideas how i make it hold my default...

I too am having this issue now.
It started after I upgraded my hard drive in my iMac flat-panel.
I backed up my old hard drive prior to upgrading, and it would automatically connect (even with OS 10.4.10), but after upgrading and restoring the backup, I have to manually connect. And what's worse is that 90% of the time, it tells me there's an error in joining my network, so I have to go to the System Prefs > Network, and basically re-enter all the information. This is becoming a pain in the a$$... any thoughts??
Also, in the Network preferences, I do not have a selection for "By default, join: Preferred Networks", only "A specific network."
Thanks!

Mac Pro won't connect to "n" network.

I realised my new iPhone would be slowing my potentially 802.11n-speed wi-fi network so disconnected it. To make sure my MacBook Pro and MacPro were connected at 'n' speed, I opened AirPort Utility and set my 500GB Time Capsule to "802.11n only (5GHz)". To my dismay, the Mac Pro no longer saw the network, while the MacBook Pro connected fine. I reset the Time Capsule to "802.11n (802.11b/g compatible)" and the Mac Pro again saw the network and connected. Given that this page: http://www.apple.com/wifi/80211/ says that 802.11n delivers "greater performance, more range, and improved reliability", I can't make any sense of the Mac Pro's behaviour.
System profiler reports the Mac Pro's Wireless Card Type as "AirPort Extreme (0x14e4, 0x88)".
Does anyone have any idea what's going on here?
Thanks in advance,
Steve = : ^ )

I just moved my Time Capsule and tried this all again and it reminded me that I'd forgotten something: after changing the Time Capsule to "802.11n only (5GHz)", the Mac Pro does see the network, but when I select it, it asks me for the network password - this is stored in the keychain and the Mac Pro usually connects without asking - and, when I enter the password and okay the dialogue, it sits for a few seconds and then reports that the connection request timed out. *From then on* it no longer sees the network at all as described in my first post. This sequence of events has happened twice now.

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extrem. How do I get Itunes to search for the music here with out trying to copy it to my laptops hard drive??

I can not store all my Music on my internal Macbook pro hard drive so I am storing it on a large external drive connected to my airport extreme (2 TB drive plugged into the USB port). I see the drive on my laptop and I can add and delete files no problem. How do I get Itunes to search for the music here with out trying to copy it to my laptop's hard drive? I don't have enough space to do that.

How did you move the music to the external drive? What exactly is on the drive? The entire iTunes folder or only music? If it is the entire iTunes folder you can do the option+start suggestion earlier. If you copied only music and did so by dragging it there then you need to delete it again and consolidate/organize it there instead so iTunes tracks the move. iTunes 12 for Mac: Change where your iTunes files are stored - http://support.apple.com/kb/PH19507

HT201250 Can I use Time Machine to backup a LaCie Hard Drive connected to an Airport Extreme onto a My Book that is connected directly to a Mac Mini?

I have a LaCie 2TB hard drive connected to a Airport Extreme Base Station. I also have a 1TB MyBook connected to a Mac Mini. My question is can you backup selected files (photos) from the LaCie drive to the MyBook drive using Time Machine, or any other software? If it will cost a fortune, I guess I can always just copy the newer files over.

Thank you for such a lightning-fast response Niel :-) Can I just double check with you the following ...?
The external drive where my iPhoto library is located has three partitions - Time Machine Backup, Pictures (where the iPhoto library is located) and SuperDuper Bootable Clone.
When you say 'Remove the external drive from the list of items set to be excluded from the backup, and then add everything else on it' - am I correct in thinking that I should remove Pictures partition from the items to be excluded but leave the Time Machine Backup and SuperDuper Bootable Clone as excluded items?
On my 2TB external drive (the one I'm backing up to) there are 5 partitions - Time Machine Backup, SuperDuper Clone, Pictures, Photo Archive and Document Archive. The Time Machine Backup is 700GB of which I still have 473GB available - when I include the Pictures folder that contains the iPhoto library that will use up another 148GB but I think there's still plenty of room to use it.
When you say if the partition contain the iPhoto library isn't dedicated to it it may be easier to create one which is, the only item I have on the Pictures volume is the iPhoto library so I think that it's dedicated to it. I was going to add images from the Pictures folder on my MacBook Pro but haven't done so at this stage so I won't do so. It wouldn't matter though, would it, if I copied the images from the Pictures folder on my MBP to the 'Photo Archive' partition of the EHD?
Thank you once more for your reply.

Do you know how to keep my mac pro air to connect automatically to wifi

I have problem keeping my Mac pro air to connect automatically to wifi .

It depends on what your settings are set at.
Are you talking about to your own Network, or are you talking about recognising and connecting to Hot Spots.
Go up to the left of the date and you will see the Airport Icon single click it and it should give you the Networks that you are in range of, You connect by choosing the network you want to join. If you need more info be more specific what you need.

My Mac Pro won't connect to Wifi?

My Mac Pro won't connect to the Wifi that it has been for the past 2+ years. All other devices in our home that use the same Wifi are working just fine.

Tried doing Network Diagnostics multiple times, did not work. Keeps saying it can't connect or times out.
What color was the light pertaining to Wifi in the left column? Red, Green, or Yellowish/Orange?
Some of the following you may have already tried:
Try the basics first:
Change your router channel number. Most times this works & is all you have to do.
Disconnect & reconnect your modem. unplug it for about 10 seconds. Plug it back in. Do the same for Apple’s routers. Wait for everything to reboot.
System Preferences>Network
Click the Assist Me button.
In the next window that pops up, click the Diagnostic button & do the necessary.

15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network.

My 15" MacBook Pro randomly loses connection to my AirPort Express wi-fi network. I have to switch off wi-fi on my Mac then switch on again to reconnect. Any reason why this random occurrence keeps happening which never happened before? Any solutions and fixes would also be welcomed.

In the airport utility, you can alter the radio modes... and change the channels from automatic to a manual one.
Hold down the Option key, and click on your wifi icon, it will tell you what channels are currently being used on your OSX.

TS3048 My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

My early 2009 Mac Pro does not connect via bluetooth to my sound bar or bluetooth mini speakers. Both my wireless keyboard and mouse have no problems connecting. What do I need to do to connect to external bluetooth devices?

I would always have a wired keyboard and mouse on hand (need not be expensive ... any cheap wired devices will work). "Emergency recovery" procedures can activate features in random order, so the opportunity to select a recovery partition may pass before the wireless devices are recognized.
That will let you select the "turn on Bluetooth" icon.

Is it possible to have two hard drives connected to my airport extreme and use one to store my itunes library/iphoto and the other to backup via time machine? Will the second (larger) drive back-up both my mac HD and my other external airport drive?

For the past year I've been using an external hard drive (HD1) connected to my airport extreme as the back-up location for time machine. This has worked fine without any issues. What I would like to do now is to move my itunes and iphoto libraries off of my laptop (space constraints) and store them on a second external hard drive (HD2) connected to the airport extreme. I have successfully connected the second hard drive using a Belkin powered USB hub. What I am wondering is if I direct my time machine back-ups to HD1 will it back-up both my mac HD as well as HD2? I apologize if this has already been answered but i've read conflicting responses on various message boards and a number of responses were dated so I wanted to make sure I received the latest information.
thank you

That may be true, but you need to know that backing-up that way is unreliable and not supported by Apple. See: Using Time Machine with an Airport Extreme Air Disk. Do not be surprised if those backups suddenly turn up corrupted.

No. Time Machine cannot back up from any network location. The 3rd-party utilities CarbonCopyCloner and ChronoSync may be workable alternatives.

Mac Pro does not connect to ADSL router

Took my mac in so that they could install airport extreme card.
When clicking on the Airport icon on task bar my router is listed in the drop down menu. When selecting it, it asks for a WPA password, after entering the password it shows the connection failed. What's interesting is that I get same error even if I type password incorrect in, it does not complain about the password being wrong.
Got a notebook with widows xp that connects fine to this router, when connecting the Mac to the router via ethernet it works fine though.
I have installed my Airport card after I have installed 10.5.2 so I was thinking it might be a good idea to maybe install Tiger or 10.5 to see if this fixes the problem as I have read many posts of people complaining about their networks after installing 10.5.2.
No idea where to start trouble shooting.

Thanks Linc. Turns out the problem was the length of the Cat 6 cable. I have wires in the walls, so I do not know the exact length, but I reckon it must be 60 ft. If I connect the mini to the switch with a shorter cable it does work. Problem is I have no way to change the distance between switch and Mini: switch needs to be where I have all the wires departing to reach endpoints scattered through the apartment, and mini needs to be where I will use it.
Any views out there on whether I need a different switch, or a different computer?

Please help me ,i forgot the synchronising password for my mac pro lion backup disk

please help me ,i forgot the synchronising password for my mac pro lion backup disk

If the backup volume is encrypted, and you forgot the password, then you'll have to erase the volume and start a new backup. There's no way to recover the password.
