AirPort Extreme (802.11n) - Which draft version of 802.11n does it use?

When the new AirPort Extreme 802.11n was announced, Apple didn't specifically state which version of the 802.11n draft it was using.
At the time of the announcement, version 2 of the 802.11n draft had not been submitted yet for approval.
So my question is what version of the Draft-N spec is it using?
1.0?
2.0?

As I understand it, the big change was going from a single 40 MHz channel to dual 20 MHz channels because some b/g base stations would get confused by 40 MHz channels, causing problems on their networks.
Here's a link to a Computerworld column about the new draft, which pretty much confirms that it's only a firmware update:

Airport Express vs. Airport Extreme... which would work best for me?

Okay, I've owned a few Apple products over the years, but have recently replaced my laptop with a Macbook Pro. So, everything in our house that uses a wireless connection is made by Apple. The only reason I say that is because my wireless router is a few years old, and I seem to be having some issues with it. So, I am probably going to replace it. I also mentioned the all-apple status because it seems to be logical that I would buy an Apple router to go along with all of this. If that's a bad assumption, please let me know.
Here is what accesses our network each day. One Macbook Pro, an iMac, two iPads, 3 iPhones, an Apple TV (about to buy another one for upstairs), and a wireless printer. I occasionally use my XBox to play online, but not heavily. We also work with teenagers at our church, and often have a group of them over at our house....and they all use the network with their phones. I don't want to just buy the more expensive router so that they can use wifi... I just mentioned it to see if that would bring out any key differences in the two. Does one support more users than the other?
Which one would you guys suggest? I obviously like the price tag of the Express, but do not want to be disappointed... Thanks!

Compare the products here:

If the primary use of the AirPort will be to provide a wireless connection to devices, then it would probably be OK.
But, you cannot connect a USB hard drive to the AirPort Express, and it does not have the better wireless antennas that are present in the AirPort Extreme.
If you need to connect Ethernet devices to the AirPort, the AirPort Extreme uses Gigabit Ethernet ports.....10 times faster than the ports on the Express. No contest there.
The AirPort Extreme will also provide a much faster 802.11ac wireless signal, but you will need to have an 802.11ac device like the new MacBook Air, MacBook Pro or iMac to realize the benefit. Other wireless devices will connect at the speeds at which they are capable.
Either the Express or the Extreme will support up to 50 wireless connections.
For me, the Extreme is a "no brainer" in terms of performance and future compatibility with newer wireless devices coming down the pike.....but if you don't need to connect a hard drive to the AirPort, you may disagree.

I am trying to extend my airport extreme signal to another airport extreme can this be done? I have tried several time using the automated set up but it keeps failing... What am I doing wrong?

I am trying to extend my airport extreme signal to another airport extreme can this be done? I have tried several time using the automated set up but it keeps failing... I have selected every possible security/password encryption level... What am I doing wrong? If it os possible where can I find step by step instructions? Please & Thank you!

The challenge with the older round AirPort Extremes are that they are "g" wireless devices.
When you configure them for WDS, the speed on the wireless network is cut in half...and probably will not have the bandwidth required to stream video reliably from either AirPort Extreme since both are affected by the WDS setup.
There is not an "automated" setup for WDS. You have to do this manually on both AirPort Extremes. Unfortunately, it is not an easy configuration and it's easy to make a mistake and hard to recover without starting all over again.
Apple's instructions for WDS are here if you want to give it a try.
http://support.apple.com/kb/HT4262
It is possible that it might work. Keep us posted on your progress
Adding a single AirPort Express will unfortunately not help. You have to have "n" wireless devices at all router points.

The timekeeping system we use does not like HTML 5 so what is the latest version of Firefox that does not use HTML 5?

We have been told by our timekeeping system provider that the latest versions of FireFox, Chrome and IE are not compatible with their websites at this time. I was told that it was because of the use of HTML 5 by the more recent versions of these web browsers. I need to download the most recent version of FireFox that does not use HTML 5. Can anyone tell me which version this would be?

It isn't "Timesheet Next Generation", is it? We had a thread on that here: [https://support.mozilla.org/questions/961306 Websites using php and mysql stopped sorting drop down lists properly starting last week. Did something change?]
Unfortunately, HTML5 is a large specification with a lot of parts that has been implemented in pieces over the course of several years. It would be really helpful if your vendor could indicate what EXACTLY is not compatible and then it could be researched. Otherwise, you'd have to use trial and error. Either way, you would end up with an older browser that isn't safe to run on the internet. It could be time to consider other vendors...

New Airport extreme dual band and older version.

I purchased a new dual band Airport Extreme base station.
How can I make use of an older version of the Airport Extreme 802.11n (non dual band) in my network?
Can I hook the 2 up together to boost up the range or coverage of the network?
If so, how far apart do they have to be?
Also, does the main AEBS have to be as close possible to the modem in order to work better? my modem is in the basement in the mecanical room. What would be the best to get the best signal througout my house?

Hello mike1970. Welcome to the Apple Discussions!
How can I make use of an older version of the Airport Extreme 802.11n (non dual band) in my network?
Two examples would be: 1) Connect the old AEBSn to the new one by Ethernet, and then, configure them for a "roaming" network. In this type of network allow you to roam with a portable wireless device and still be on the "same" network, and 2) Configure the old AEBSn to extend the wireless range of the newer one in what is called a dynamic WDS. The major difference between a WDS and the roaming configuration is that the two base stations would not need to be interconnected by Ethernet.
Can I hook the 2 up together to boost up the range or coverage of the network?
Yes, both only one of the newer AEBSn's wireless radios. Most likely, it would need to be the 2.4 GHz radio as the signal can travel farther and not be impacted by objects ... like walls.
If so, how far apart do they have to be?
That would depend on what would be between them. In a room with no Wi-Fi obstacles, you could probably place the second AEBSn 50-75 feet away to boost the signal another 50-75 feet.
Also, does the main AEBS have to be as close possible to the modem in order to work better?
No.
my modem is in the basement in the mecanical room. What would be the best to get the best signal througout my house?
The best way would be to have the house wired for Ethernet, and then, place a Wireless Access Point (WAP) at each location that you would want wireless coverage.

Airport utility no longer recognizes my Airport Extreme Base Station, which had been set up to extend a wifi network

Hi. In November I set up my airport extreme base station (5th generation I believe) to wirelessly extend the wifi network we use at home to see if it would increase download speeds. Before doing that, I did a factory reset of my airport extreme, and the owner of the airport extreme to which the ethernet cable is attached made changes to his network to allow it to be extended. I folllowed all the directions from the apple support pages, and finally got it to work. I could even access a portable hard drive which I attached to the airport extreme base station being used as the extension. Then a week or so ago I noticed that my laptop would no longer connect to my base station. I did not have time to look into it until this week. Airport utility, either on my Mac or iphone no longer recognizes my base station. My mac is running OS X 10.10.1 and my iPhone is running iOS 8.1.2 I have tried both hard, soft and factory resets of my base station to no avail. The only thing that has changed after doing that, is that when I do a soft reset of my base station, a neighbors airport express appears when it never did before. I can't actually connect to it, but it does try. Then after approximately 5 minutes, it disappears from my list.
Today I went and pulled out my OLD AIRPORT EXTREME base station... you know, the one that looks like a space ship and is running wifi 802.1 b/c? airport utility DOES locate and display that, but airport utility returns a message stating that it cannot be set up by this software. I am attaching an image of that.
Thank you,
John
Does this have anything to do with the fact that 'Back to My Mac' is probably enabled?

I think the initial problem is that your iPhone was connected to an open network that wasn't yours.
Go to Settings > WiFi and "Forget" the network created by that AirPort Extreme, it's older than dirt. Forget your neighbor's network also.
Perform the equivalent actions with your Mac: System Preferences > Network > Wi-Fi > Advanced... Delete every network that appears, including your own.
Then, connect to your own network on all your devices, after which you ought to be able to use any of them and configure your Extreme without any difficulty. You may need to start over with a "hard reset" on both the main AirPort Extreme and the one extending its network.
Does this have anything to do with the fact that 'Back to My Mac' is probably enabled?
Not exactly, but using iCloud Keychain will populate all your devices with the names of preferred networks that any of them connect to, no matter where they are. I don't know why Apple considers that a beneficial feature.

The Airport extreme vs vingor2750vn, which is better?

I want to buy a Airport extreme,
But is it better than the vingor2750Vn,
because my internet is really slow.
Maybe if I get the Airport router from apple
my internet will inprove.
But I am not sure if it will help

It is basically the same.. range, performance of wireless and router should be identical or very near to.
See the review here which compares them.
http://www.anandtech.com/show/4577/airport-extreme-5th-gen-and-time-capsule-4th- gen-review-faster-wifi-/4
The advantage of the TC is time machine.. Airport extreme might work for TM but apple do not support it and lots of people have issues with it.
But if you are not going to use Time Machine with the TC then there are cheaper and better options.. especially for windows.

I bought airport extreme to increase coverage in my 2 story home. It uses an ethernet connection. There are dead zones which I had hoped to cover with the addition of the airport extreme, but it didn't help. Any suggestions?

I bought an airport extreme to increase the coverage in my 2 story home. I get good fast coverage in some spots on both floors, but complete dead zones in other areas. The airport extreme did not help. It is connected by ethernet to my cable modem which has a high speed connection. Is there a configuration I should try to help with these dead zones?
Thank you- CC in Minneapolis

Please check out the following AirPort User Tip for details on how to best place your base stations for maximum coverage.

I have an airport extreme space station which works fine, but does not ask for the password so anyone can get on my network. I don't know what to do to fix this.

I set up airport wifi with a WEP password, but it never asks for the password and anyone can enter my network...what to do?

Is it possible to backtrack your way out of the keychain?
Yes:
Run the Keychain Access utility found in \Applications\Utilities
In the category column (on the left side of the utilities' window), select "All Items."
In the right column look for your Network Name. It will have a "Kind" of "AirPort network password."
Delete every entry that has both your Network Name with this Kind.
What can I do to test or reset?
You can completely erase all the base station's passwords by performing either a "hard" or "factory default" reset. You can also temporarily disable these passwords for up to five minutes so that you will have enough time to change them using the AirPort Utility, by just performing a "soft" reset. I would recommend this one first.
This would also be a good time to consider using WPA or WPA2, instead of WEP, as WEP is no longer considered secure.
I got the airport extreme based used with no softward and set up with reset on airport base and followed instructions.
You can download a copy of the AirPort Utility, that runs on OS X Tiger here.

Can I use an airport extreme if my imac is version OSX 10.6.8?

I just bought an airport extreme to hopefully expand wifi coverage in my home. When I opened the package I noticed that OSX 10.7.5 is required. My imac is OSX 10.6.8. What recommendations are there for me short of buying a new computer?

Or you could update your OS to Mavericks 10.9 (free) so long as your Mac meets the specs, you have at least 4gb of RAM and don't rely on any older apps in your workflow - especially PPC apps as they definitely won't work.
If you do upgrade thoroughly research it first and ensure you have full and up-to-date backup your can restore from if you're not happy with the upgrade. Time Machine or a clone of your HD are both good options. I prefer the clone as it seems to be easier to ensure everything is perfect and that it works. It's also quicker to restore from, in my experience.

How to configure Airport Extreme AFP disk sharing to host multiple users' home-directories (Lion, using autofs)

I have this working, but only by completely bypassing access control, using guest access with read+write permissions.
Do I need to buy Lion Server, to do this. All my past unix/linux experience says Lion Server should _not_ be necessary.
This seems like a simple & obvious setup objective, but it is proving to be harder than I would imagine.
Setup:
multiple users, sharing two mac mini's running OSX Lion
connected to an Airport Extreme (4th gen) with a USB disk shared (either via disk password, AEBS password, or using AEBS user's passwords).
After much experimentation and web research, I finally have managed to get the mini's to auto mount the Airport Extreme's AFP shared USB disk. Well almost... It only works if, on the Airport, I set the guest access permissions to read+write and select the "Secure Shared Disks" method to "With disk password" or "with Airport Extreme password". In other words, it only works if I essentially bypass/disable access control by using the guest authentication mechanism to the AFP shared disk.
On the Lion side of this, I am automounting the users directories via "autofs". The config files for this are
/etc/auto_master:
# Automounter master map
+auto_master            # Use directory service
/net                    -hosts          -nobrowse,hidefromfinder,nosuid
/home                   auto_home       -nobrowse,hidefromfinder
/Network/Servers        -fstab
/-                      -static
/-                      auto_afp
/etc/auto_afp:
# Automounter AFP master map
# https://discussions.apple.com/thread/3336384?start=0&tstart=0
/afp/users -fstype=afp afp://;AUTH=No%20User%[email protected]/Users/
Then, after rebooting and verifying read+write access to the /afp/users directories, I change each user's home directory: In System Preferences > System > Users & Groups, I right-click over the users to access the Advanced Options, changing the Home directory field to point at the AFP-mounted /afp/users/Users/* home directories.
I experimented with alternate UAM specifications, as well as both OSX and AESB users & passwords. Using guest access is the only thing that has worked.
Any pointers would be appreciated...

Based on lots more experimentation which confirms the information in a parallel discussion (cf. Automount share as non ROOT or SYSTEM user! https://discussions.apple.com/thread/3221944), I have concluded that the Lion 10.7.2 implementation of AutoFS mechanism is broken. I submitted a bug report via apple.com/feedback.
Work arounds..?
Earlier I wondered if installing Lion OSX Server was necessary. The more I contemplate this, the more I am convinced it _should_not_ be necessary. The client-server architecture is clear: my mac's are the file-server client's and the Airport Extreme is supposed to act as the file server. The only thing instaling Lion Server would do (besides enriching Apple.com) is enable me to configure one of the mac's as the file server. This would require it to be "always on" (thus enriching my electric utility as wel). Okay, an additional benefit would be configuring software RAID disks attached to the Lion server, but Time Machine has worked fine for me in the past, backing up to disks mounted on the Airport Extreme.
One solution is to create a disk partition for each user and instruct each user to connect / authenticate to the Airport Extreme AFP share at login. The multiplicity of partitions is necessary since the first user to mount the AFP share, takes ownership of it, blocking other users from accessing that disk partition. A user can "steal" ownership by reconnecting, but this will leave the other user's applications & open files dangling.
This disfunctional situation really *****. Before instaling Lion, I put a 64 GB SSD (solid state disk) in each of our mac's. I did this expecting to easily configure the /Users/* data on external networked storage. I'm having a dejavu "Bill Gates"-ware moment; problems like this were why I abandoned Windoz.
I will make a few more experiments using the depreciated /etc/fstab mechanism. Maybe that will bypass the broken-ness of AutoFS...? Alternately, I guess I could also try to run Kerberos authentication to bypass whatever is broken in AutoFS, but that would require a running a Kerberos daemon somewhere. Possibly I could configure a Kerberos service to run on both my mac's (without installing Apple's Lion Server)...?
Stay tuned...

Cant upgrade Airport Extreme on Macbook Pro Core Duo to 802.11n

I have an original Macbook Pro Core Duo, purchased not long after Apple's announcement of "Bootcamp", and it has a "Wireless Network Adapter (802.11 a/b/g).
From what I can tell from various documentation around the web, this should be upgradable to 802.11n with Apple's 802.11n Enabling software, however it tells me that the hardware is not compatible.
If anyone can suggest what I am doing wrong, or whether I miss out, that would be good.
Also, assuming it can not be upgraded, will running my local Airport network in "802.11n 5GHz 802.11a compatible mode" affect the speed of my other 802.11n devices on the network?
Thanks.

So you're basically saying 'Link Speed' shows the current connection? If so, the problem resolved itself. Sorry, my bad. Thanks anyways.
(My Time Capsule hasn't arrived yet. I'm currently using an older version of Airport Express.)
Another thing. When I asked at the local Apple Center for the 802.11n card, they told me, the card itself is not sold separately and even if so, it could not be exchanged, since it's unremovably attached to the logic board. Why do they tell the customers something like that? I mean, if Apple doesn't want the users to make changes like that, fine. Then they should say so. But why make up stories in order to dissuade people from their ideas? Is that common policy?

Hi I am having problems with my old airport extreme base station. It is a 802.11g with airport utility version 5.5.3.

On a regular basis connection is lost by al of the apple products connected to it even though signal strength is still showing to be good and its green light is still on. The only way to resolve seems to disconnect it from the power and then reconnect. All the apple products connected to it are more up to date than the bsae stationis this the problem?

All the apple products connected to it are more up to date than the bsae stationis this the problem?
I think it may have more to do with the older AirPort Base Station failing than it has to do with the fact that you have newer Apple products.
One option is to perform a "factory default" reset on the Extreme, and then, reconfigure as required for your networking needs. If after this type of reset, the Extreme still acts up as you described, it may be faulty or about to fail.

Bridge Airport Extreme and Time Capsule together? (both 802.11n)

Hello all,
1) I just picked up a used time capsule (1TB) to replace my AE and start backing up. I was going to try to sell the AE. I have heard they can be bridged together to create a stronger wireless signal. The phrase "wireless relay bridge" has been thrown around. Can anyone tell me if this is possible and how to do it?
2) Also curious if either TC or AE can be placed in separate areas (levels) of the house to 'spread' the signal around better. The Basement is the current location for everything.
Thanks...Jimmy

First, you need to make sure that your TC is setup correctly. So check that device using AirPort Utility - Manual Setup
Click the Wireless tab/label just below the row of icons
1) Make sure you have a check mark next to "Allow this network to be extended"
2) Jot down the exact security setting that your TC is using as you will need this later
Update to save changes on the TC
It would be a good idea to "hard reset" the AEBS to start fresh, so hold in the reset button on the device until you see the amber light begin to blink more quickly. Hold another few seconds when you see this and then release.
It's also a good idea to configure the AEBS near the TC, then move it to the desired location once you have it setup. You can configure the AEBS using wireless, or if you have a spare ethernet cable handy, you can connect using ethernet. Connect the cable from your computer to one of the LAN <-> ports on the AEBS.
Open AirPort Utility - click Manual Setup
Click the Base Station tab below the icons to name your device, assign a device password and adjust Time Zone settings
Click the Wireless tab
Wireless Mode = Extend a wireless network
Wireless Network Name = click on the arrow on the selection box and the name of your TC network should appear. Click to select or type in the exact name of the TC wireless network
Check mark next to Allow wireless clients
Wireless Security = Exact setting that you wrote down from the TC settings
Wireless Password = Same password as your TC wireless network
Confirm Password
Click Update to save settings. If you used the ethernet cable, you can disconnect it and close Airport Utility as soon as you see the message that the settings have been stored. You should get a green light in about 30 seconds.
Now you can move the AEBS to a location where it will receive a strong signal from your TC and it will "extend" the wireless network for greater coverage.

Airport extreme time capsule yellow light - no Internet - cable modem does work

Is their a reset button on the time capsule or am I out of luck.
Yes I have turned on and off etc. the cable modem has been tested and is functioning ... Do jthese units go bad.
Thanks friends

Airport Extreme
or
Time Capsule
These are two different devices?
You have a yellow light on both of them?
However, yes, you can reset either one of them.
A yellow light could mean there is just an update for each one of them.
But if yours isn't working there is another problem.
See this Apple doc about the blinking yellow light:
