How many ip addresses will an airport extreme handle?

I have about 60 devices in my home that need an IP address and can only imagine with the Internet of Things, wearables, security etc. that it will go higher in the future.
How many IP addresses will an Airport Extreme or Time Capsule handle reliably?
Thanks -

About 250 total wireless and Ethernet addresses, with a limit of 50 for wireless devices........assuming that it is the AirPort Extreme or Time Capsule that is acting as the router handing out the IP addresses.

How many CS Increments will it take to handle ProRes Correctly

Two Simpleton-tests with AE 5.5 revealing that AE still hasn't learned a darn thing in regards to the ProRes Codec
Test 1:
1) Import ANY Canon 5DMKII into AE CS5.5
2) Add it to a new Comp
3) Add that comp to the render queue
4) Select ProRes 4444 as output codec
5) Render and compare with your original Canon Footage
Expected Result in the Quicktime Player 7:
The ProRes File Should look somewhat like the original.
It does NOT.
Actual Result
Gamma is WRONG
Color is slighty shifted
And Noise/banding has been increased significantly.
Test 2:
1) Open Apple's Compressor
2) Import the same Canon File
3) Setup a 4444 Codec like in AE
4) Render out
Expected Result in the Quicktime Player 7:
The ProRes File Should look somewhat like the original.
It does.
Actual Result
ProRes transcode looks 100% identical to the source
Test 2 Expanded
Import the Compressor-created 4444 file into AE and repeat test 1
Expected Result in the Quicktime Player 7:
The ProRes File Should look somewhat like the Compressor-Created file.
It does NOT.
Actual Result
Gamma is TOTALLY WRONG
Color is LESS shifted than when exporting the Canon file directly
Noise/banding is MORE than the compressor created file but LESS than when exporting the canon file directly...
I am more or less speechless. I have been reading about this problem on a million blogs. Including adobe's own.
Since at least since CS3. There have been several invain work-arounds. And now this. CS 5.5 - with the same problem.
Adobe, how many versions do you need to get it right.
Perhaps, you could look a little a Apple's technology, as it seems to be much more effective and advanced than yours.

Hi Rick,
first things FIRST ;-)
Thank you very much for taking the time to make that post.
My color settings in AE are correct. And I am using a color managed workflow -)
It plays NO PART whether I enable the "Use Legacy Gamma"....
Your example is correct in BUT it only applies to the realm in which you created it > RGB
and it does not exhibit temporal H264 artifacts stemming from a YUV 4:2:0 (609 Color Space) Matrix
You dont exaclty round-trip the way that I was describing a rountrip in my initial post.
I know that a ramp can reveal certain things but it is a highly virtual comparison and does not really apply to live-worl footage.
At least in this case ;-)
You take RGB-generated grays and then output to ProRes
I took a YUV-color-realm movie entered into the realm of RGB (AE) and then exported to ProRes
And THAT is where the problem lies.
I am uploading the file in question. It is a movie from the 5DMKII.
That is the source I have been testing with all along.
It is great in that it has a dark area with quite a bit of noise. THAT noise after AE has encoded it to ProRes will look banded and become worse.
Not so when encoding with Compressor.
Besides, and this I cannot wrap my head around, when compressor is compressing the exact same file it is 295MB in size but when doing it with AE it is 413.
Something wrong there ?
Anyway, here is the link to the file if you wanna try with that.
I am uploading a screen shot to show you which area you should look out for.
And rememeber this is NOT visible when looking at it in AE. you HAVE to rountrip and open the source and the rountripped file in the Quicktime Player.
Remember, most folks are WATCHING the movies in the quicktime player on OS X... So I would LIKE my files looking identical to the source when watched in the QT player. I dont believe that any consumer out there, just aiming to watch a movie has AE installed so that he can watch the movie in the way I (all AE users) intended it to look.
Adobe we NEED this to work.
When/if you do the test - make a real world comparison.
Open the Original source in AE and out-encode it to PR4444.
Then open the quicktime player and load up both (PR4444 and ORG source)
Put them on top of each other and flip back n forth. Huge difference in the area that I have hi-lighted in SS below.
The noise in the original is very present in the original file in that area...
When looking at adobes encode the noise has become large square fields(almost) looks a little like banding.
When using Apple's compressor to rountrip it looks exactly like original.
Might I add, taking the original file and opening it directly in AME (bypassing AE altogether) will have the same impact on the file
as when exported directly from AE. So it seems as if adobes Quicktime encoding framework has a bug altogether. I tried all of this with the
cineform codec as well. When using adobe to encode to cineform it displayed the same artifacts.

How many client connections will iMQ 2.0 handle?

My main concern is what the number of concurrent client connections (in a single instance) iMQ
can handle? This also depends on Hardware/Software configuration, JVM version (if it pure Java implementation), etc. But it also depends on Vendor implementation. For example FioranoMQ claims that can handling more than 5K concurrent client connections in a single instance of the FioranoMQ server without leading to any substantial performance degradation when a low number
of clients are connected to the server.

With proper tunning iMQ 2.0 can handle thousands of simultaneous connections.
For example on a modest Sun system (Sun Ultra 60/2300 (2x300MHz) 512MB ram)
We have run 4000 active connections without a problem. With more memory the
system could have supported more.
The iMQ FAQ gives some tuning guidelines for configuring the iMQ server
(the broker) to handle large number of connections. I'm attaching the
relevant excerpt (the online FAQ is a bit out of date).
When I try to connect more than 500 clients to the Broker's JMS service, performance gets really poor. Is there a way to configure the
Broker to handle more connections with better performance?
Yes. By default the JMS service's thread pool is limited to 1000 threads. The Broker runs best when it can allocate two threads per
connection. Once the thread pool limit is reached, threads are shared and performance decreases.
The solution is to:
1.Increase the thread pool limit for the JMS service so threads are not shared.
2.Configure the broker's socket read timeout so read threads fully block.
3.Configure the JVM to improve performance in highly threaded applications.
4.And if you are running on Solaris and plan on going over ~1000 connections you will also need to:
Increase the maximum number of open file descriptors per process.
Step 1: Increase thread pool limit for JMS service
Set the jmq.jms.max_threads property to be 2X the maximum number of connections you wish to support. For example if you want to
support 1000 connections you will need to set the property to 2000. You can do this by adding the following line to
$JMQ_VARHOME/stores/<broker instance name>/props/config.properties:
jmq.jms.max_threads=2000
Or by running jmqcmd:
jmqcmd update svc -n jms -o maxThreads=2000
Step 2: Configure the broker's socket read timeout
Set the jmq.protocol.timeout to 0 to cause read threads to fully block in read. Do this by adding the following line to
$JMQ_VARHOME/stores/<broker instance name>/props/config.properties :
jmq.protocol.timeout=0
Step 3: On Solaris pass additional parameters to the JVM
If you are running the broker on Solaris you should pass the following parameters to the JVM:
-Xss128k -Xconcurrentio
The first parameter reduces the per-thread stack size to 128k. The second adjusts several internal JVM parameters that significantly improves performance of highly concurrent applications.
You may pass these to the broker by using the -vmargs option to the broker command or you may choose to alter the $JMQ_HOME/bin/jmqbroker script by adding "-Xss128k -Xconcurrentio" to the line that starts with with "def_jvm_args". For example you would end up with a line that looks like:
def_jvm_args="-Xms8m -Xmx128m -Xss128k -Xconcurrentio"
Note that if your system has sufficient RAM you may also want to increase the JVM max heap size parameter (-Xmx128m).
Step 4: On Solaris Increase the maximum number of open file descriptors per process
This is covered in the iMQ 2.0 documentation. One way to do this is to run 'ulimit -n unlimited' in the shell you are going to run the broker in.

How many people can simultaneously share airport express network?

How many people can simultaneously share airport express network? I want to set up a wireless network in my classroom and need to accommodate about 25 devices.

The AirPort Express will only handle 10 wireless connections.
You will need to consider an AirPort Extreme....which will handle up to 50 wireless connections.

How to set up 6th Generation AirPort Extreme to cable modem as a wireless router and then connect my 3rd Generation Time Capsule to AirPort Extreme as a wireless extender?

What is the best way to set up my 6th Generation AirPort Extreme (A1521) to my cable modem as a wireless router and then connect my 3rd Generation Time Capsule (A1355) to my AirPort Extreme as a wireless extender? I live in a small 1 story house and I currently have the Airport Extreme connected to my cable modem in the living room and the Time Capsule plugged into the wall in my bedroom. I am able to wirelessly connect to the internet using the AirPort Extreme as my router and I can also do wireless back ups to my Time Capsule. My problem is that my connection seems to be really slow! My 1TB Time Capsule back up is only half way complete and it has been 3 days! My computer has been backing up all day and night for almost 72 hours and its still not even 75% complete. I have backed up to this Time Capsule in the past and it never took this long. I am thinking that when I set up my AirPort Extreme and Time Capsule using AirPort Utility I must have set it up incorrectly or something.
How do I set up my Airport Extreme and Time Capsule for the fastest possible internet speed and back up speed?
Thank you,

AirPort Utility 5.6 works with AirPort Extreme 802.11g base stations.
It works with N version airports.
It will also show details of the AC model but cannot be used for the setup.. mostly.
I purposely got the new 6th Gen Airport Extreme so my internet connection would be a lot faster!
Your network will be much faster when you have AC client directly connected to the AE. Older client will go no faster.. but what is worse.. extend wireless is mixing new and old wireless standards.. guess what one wins.. OLD.. So when you extend wireless.. you have no improvement whatsoever. This whole post is about extending wireless.. so you cannot extend to older equipment and do any better.. maybe slightly better signal although from your comments that isn't happening either.
I would rather not have to use an ethernet at all with the TC and I don't know EOP adapters are!
If you do not use ethernet then you are going to be forced to accept slow speed.
EOP (ethernet over power). Also called homeplug in the US.
http://en.wikipedia.org/wiki/HomePlug
Provides a method of networking over power cabling that already exists in your house.
So what your saying is for the fastest internet speed and back up speed possible I should keep my Airport Extreme plugged into my Modem and keep my TC set up as a wireless extender? Then when I want to do back ups I should plug an ethernet cable from my TC to my MacBook Pro?
To spell this out.
A wireless link to an extended device will go very slowly.. if it is not direct.
So lets say you have a laptop sitting in the lounge.. Your connection goes.. Laptop- - - - - AE- - - - -TC.
That means two wireless links.. wireless has this nasty half duplex and single channel nature.. it can send or receive (Tx or Rx) but not at the same time.
Ethernet by contrast does both at once. It is full duplex.
Wireless can talk to one client at a time.. so if there are multiple items using wireless lets say 4 devices.. then your computer gets a 25% time slice. Since wireless cannot handle multiple simultaneous connections.
Ethernet by contrast can connect multiple computers to multiple destinations at the same time.. all transmitting and receiving at full speed.
When you put all this together.. there are a couple of rules for fast connection.
1. Use ethernet at all times. Where you cannot use ethernet use anything but wireless.. eg EOP (homeplug) at least to try and get rid of wireless.
2. Where you must use wireless use it sparingly and make sure it is never more than one hop.. ie never have an extend wireless (repeater is more usual term). Repeater will cause instant slowdown of 50% and maybe up to 75% just because it is so inefficient.
3. Fastest wireless is 5ghz but it has very short range.. you need to be up close and personal to get it working.
Apple routers however unless you do manual setup I suggest are set to connect to best signal strength not best speed. It will therefore use 2.4ghz at 25% less speed than 5ghz because it is 1db better signal.. this madness means you need to setup manually for the best setup.

How do I make my new Airport Extreme a base station?

I have been using an Airport Extreme (5th generation) as my base station router for a few years. I set the main network for my and my wife's use and created a guest network for when my sons visited and needed to use the wi-fi connection. I used passwords for both networks. Today I purchased a new 802.11 ac Airport Extreme. I unplugged the 5h gen. Extreme and plugged in the new Extreme. After a short hunt, my new 27" (late 2013) iMac found the new Extreme and had me set up a name and a password for it using Airport Utility. I was expecting it to ask if I wanted to set up a guest network, but it did not. I was expecting it to ask since I believe that is what happened when I installed my 5th gen Extreme a few years ago. For the 5th gen Extreme, I had to enter a password to protect settings on the Extreme, a WPA2 password for my main network and another password for my guest network. It took about 10 minutes to set up. For this new Airport Extreme I entered just one password. It took about 2 to 3 minutes for the entire setup. When I checked the menu in the Airport Utility under "Base Station", all lines are grayed out. Under the File Menu in Airport Utility, "Configure Other" is available, but "Import Configuration file" and "Export Configuration file" are also grayed out. I checked Network Settings in System Preferences and I see my new network name in the Wi-Fi menu and under the "Advanced..." button, I see the old and new Networks listed in the "Preferred networks" box.
So, how do I get the new Airport Extreme to act as the Base station and be able to enter a guest network? Does it require me to delete the old Network name from the Advanced... button page in System Preferences > Network Settings? Will I just have to start all over with the new Extreme to make it a base station?

Hello Leo,
I'm not at home so can't confirm but I can only assume that maybe some of the "old" settings in airport utility have changed, and simplified. Hence why you probably only need one password.
When I bought the new "tower" like AirPort Extreme, I just plugged it into the Ethernet, powered it on with the previous generation Extreme in place and in Airport Utility it just asked me if I wanted to copy the settings to the newer device, which included a few "port forwarding" settings. All done in this sequence. I didn't have guest network set up but you can still set up guest network under wireless in Airport Utility, hope this helps!

How do i use a 2nd airport extreme both are newer models

how do i use a 2nd airport extreme both are newer models

I assume that you mean that you want to extend the range using wireless only.
This Apple Support Document will tell you exactly how to do that:
http://support.apple.com/kb/HT4259
The instructions assume that you have AirPort Utility 5.6 for Mac OS X Lion , so if you have not already done so, you will need to download and install this application to track the instructions in the support document.

Where can I find the MAC Address of a Airport Extreme ?

Where can I find the MAC Address of a Airport Extreme ?
I need this to extend the wi fi range in my home. I'm using a Motorola Cable modem and to extend with Airport Extreme, I need to set up inside Motorola the MAC Address of the Airport Extreme.
Message was edited by: JPA3003

There are actually 3 MAC Addresses on an AirPort Extreme......1 for Ethernet, 1 for 2.4 GHz wireless and 1 for 5 GHz wireless.
You can normally see them by using AirPort Utility. The rub here is that the AirPort needs to be setup and working to be accessed by AirPort Utility.
The other approach is to look on the bottom of the AirPort. The newer AirPorts usually have this information in very small print, so a magnifying glass will probably be required. Other versions embed the numbers in the foam mat.
Note.....Apple uses proprietary settings for the their wireless "extend" feature.....designed to only allow other Apple devices to connect. So, it is extremely unlikely that the AirPort would be compatible with a 3rd party router if you are trying to use the AirPort to wirelessly extend the network.
Let us know if you are able to do this.

How do i set up my airport extreme to access from my work windows based PC

How do I set up my airport extreme to access from my work windows based pc?

To mount the AirPort Disk in Windows 7 or Vista:
Open the Network browser by double-clicking Network on the Windows Desktop.
The AirPort Extreme base station name should appear in the browswer.
Double-click the name and you should get a login prompt.
Now depending on how you set up disk access:
In the Name field, either enter the user account name or for base station/disk access, leave this field blank.
In the Password field, enter the base station, disk, or user account password.
Select the volume(s) you want to mount, and then, click OK.

How do I set up my Airport Extreme to best use multiplayer games locally

How do I set up my Airport Extreme to best use multiplayer games with my family. Everyone is located in the same house and uses the same router.
I have tried a few games but have not successfully connected 2 players

That is a weird question, as your GAMES could be interpreted a hundred different ways. Are we talking about third party devices here or what?

Will adding AirPort Extreme to my fios router improve my speed and distance to led tv.. The tv keeps dropping network and 50% of the time it tells me my broadband is too slow. I have upgraded to fios faster internet speed.

Will adding AirPort Extreme to my Fios router improve reception on tv located about 50 feet away..have new top of the line samsung smart tv and it drops signal every other day. When trying to watch netflix or amazon it transmits in SD only says bandwidth is not high enough for Hd. My ipad laptops and iphone work fine in this room. Any help will be appreciated or am I better off with a booster.

The AirPort Extreme will not be able to wirelessly "boost" or "repeat" the wireless signal from the Fios router, since It will only work with another Apple router for that feature.
So, if you plan to extend or repeat the FIos wireless signal, you should use a product by the same manufacturer as the Fios router....or possibly a "universal" repeater from a company like Netgear.
Make sure that you understand the store's return policy before you buy any kind of extender or repeater.....since you cannot know if the product will help until you try it out in your home.
The TV really needs a wired Ethernet connection from the Fios router if at all possible.

I'm trying to back up 10.6.8 (snow leopard) and all my files before upgrade to Mavericks. I have an old but sturdy external hard drive...how many GB available will I probably need to back up the whole thing? thanks!

I'm trying to back up 10.6.8 (snow leopard) and all my files before upgrade to Mavericks. I have an old but sturdy external hard drive...how many GB available will I probably need to back up the whole thing? thanks!

You will need a separate partition unless you plan to use the entire drive. You will need an amount of space somewhat larger than the total space now used on your startup drive. If you select the startup drive's Desktop icon, then press COMMAND-I to open the Get Info window. Used space will be shown in the topmost panel. Add a GB or two to that number to determine how much space you'll need for the backup.
Do not backup on a drive that has any files you want to keep. You can make a bootable backup as follows:
Clone using Restore Option of Disk Utility
1. Open Disk Utility in the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

How do I extend my existent Airport Extreme network by addition of a 2nd Airport Extreme?

Can you clarify which version of the AirPort Extreme that you have now along with the model that you plan to use as the second device?
The older "round" AirPort Exteme or the newer "square" version with rounded corners?
Are you planning to extend using wireless only.....or by connecting the AirPort Extremes using a wired Ethernet connection?

Will my airport extreme 2nd generation work with docsis 3.0 cable modems?

Will my airport extreme 2nd Gen work with docsis 3.0 cable modems?

RRoger, everything is working fine.
So, what is the actual problem here? You are now wondering if the Vonage can handle the speed from the modem? Is that the "problem" after all this discussion?
now I am wondering if my current setup will allow me to get docsis 3.0 speeds.
What speed is your Internet provider delivering to you?
The AirPort Express uses 100 Mbps Ethernet ports, so it will handle up to 100 Mbps. We have already told you that.
Vonage likely does the same. The answer is almost certainly "yes" .......both the Vonage and AirPort will handle the speed from the modem.
If you want to double check this, please provide the model number of the Vonage, and we will try to look up the specifications for the device. If you have documentation there with specifications for the Vonage device, check to see if the Ethernet ports are listed as 10/100. This is standard with almost all devices, with some of them handling even higher speeds 10/100/1000.
Chances are, your network will handle a lot more speed than your service provider is supplying to you. So, the "choke" point on your network may very well be your service provider and modem......not the Vonage and AirPort.
