My airport only allows one device at a time

I recentley upgraded my modem but now I can only connect one wireless device at a time. Suggestions?

If you are using a Mac running Lion....
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort icon, then click Edit
Click the Network tab
Make sure that the setting for Router Mode is set to DHCP and NAT
Click Update and the AirPort will restart in 25-30 seconds
If you are using Leopard or Snow Leopard.....
Open Macintosh HD > Applications > Utilities > AirPort Utility
Select the AirPort and click Manual Setup
Click the Internet icon, then click the Internet Connection tab
Make sure that the setting for Connection Sharing is set to Share a public IP Address
Click Update to save the settings and allow 25-30 seconds for the AirPort to restart
With either configuration above......
Now power cycle the entire network as follows:
Power off each device in any order that you wish. Make sure that the power cord is pulled from the back of the modem, or from the wall AC outlet
Wait a few minutes
Start the modem and let it run 3-4 minutes by itself
Start the AirPort and let it run 2 minutes by itself
Start each network device one at a time about a minute apart
Check the network

Time capsule only allows 2 devices at a time as a router. If I am using the iphone and macbook pro, it bumps the roku offline. Any suggestions?

At a guess you have cable internet connection.. please confirm exactly what you have.. two public IPs are allowed by some ISP.. once you use up the two IPs, there are no more..
Make sure the TC is in router mode. And to get it working you probably need to shut off the cable modem.. if it has battery backup remove the battery.. try 5min off .. if not long enough try 20min off. then overnight. The ISP equipment must reset to allow a new MAC address to capture the IP.
If you cannot work it out.. plug in the old router again.. and set the TC to bridge mode.. which I suspect it is in now.. and plug it into the main router.. it should work fine like that.

The airport on my Time Capsule will now only allow one device to connect at a time.

When I first installed my new time capsule, everything worked beautifully. I had multiple devices connected to the AirPort and life was good.
A few weeks ago, I swapped my cable modem and everything went bad from there. Now I can only connect one device wirelessly at a time.
After lots of back and forth with Time Warner, a swap of the modem and may hours with tech support, it has been determined that my Time capsule is not assigning the 2nd, 3rd... devices a proper IP address. Instead, the IP addresses all begin with 169.
What advice do you have. Is there a way to reset the whole darn thing? At this point, I am okay if I lose all of my backups.
Thanks!

What is the cable modem?? Make and model please.
What model is your TC.. A1xxx from the base please??
I suspect the issue is the TC is bridged and you have a pure modem.. you need to change it over to router mode..
Here is what you need to do to setup the TC..
The list is over long perhaps but is based on best network practice for Yosemite which is rather more than problematic.
You don't say what OS you are running.
Once you do this.. you also need to power down the modem if it is pure modem type (which is all that makes sense here). Leave it off for 20min while you do the setup of the TC and then power up the modem wait a couple of min and power up the TC..
Expect serious issues if the modem is SB something.. 6121 or 6141 for example. And your TC is AC model.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

Can I use Photoshop cloud on my iMac and MacBook Pro as long as I'm only using one device at a time

does a subscription allow a user to have the software on two devices as long as it is being used on only one device at a time?

Hi jeff 5dii
Yes, you can install and activate Creative Cloud desktop applications on two computers, regardless of operating system, for use by the individual associated with the membership. See the product license agreements page for more information.
Thanks

Time Capsule which will only let me connect to one device at a time. Anyone else experience this?

I have a Time Capsule which I use with a Macbook Pro and an iMac, as well as my iPhone and an Airport Express. It appears as though it will currently only allow me to connect to one device at a time. I had my MBP and iMac sitting side by side and ran Aiport Utility on both. The Time Capsule would only show up on one or the other but not both. Anyone else experience this? It was working great until a day or so ago.

It sounds as if your Time Capsule is in "Bridge Mode", which would only allow one device to connect to the Internet at a time.
To check......
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click Manual Setup
Click the Internet icon
Check the setting for Connection Sharing
If it is "Off (Bridge Mode)", change it to "Share a public IP address"
Click Update to save your changes

WRT54G only allowing one unit to attach to static IP printer

Hello, I have a small network in a classroom with one printer with a network card.
I have made that printer a static IP 192.168.2.50.
Wireless PC' have no problem attaching and printing.
For some reason... when I attach a wired PC to that printer using an IP port connection using tcp/ip it only allows one PC at a time to attach.
Is this a setting in the WRT54G or should I look to the network card.

i don't think it has to do anything with the router...because had it been the router , even the wireless computers wouldn't have worked...
so it seems to me an issue between the network card...

Is there a stereo bluetooth headset that can pair with more than one device at a time?

Is there a stereo bluetooth headset that can pair, i.e. multipoint, with more than one device at a time?
Are the MacBook and iPhone 4 capable of multipoint bluetooth technoloagy?
The goal is for my wife to be able to watch her Korean TV soap operas on her MacBook and still receive a call on her iPhone 4 via a stereo bluetooth headset.
I was looking at the Motorola S10-HD but after further review saw that it only pairs with one device at a time.
Appreciate any and all input. My Googling has returned no results.

You can only pair one device at a time to your 8330, or any other phone for that matter. The "pairings" are saved to the phone, you can use one or the other and you won't have to pair it again. Once you turn your bluetooth device on and the phone is on, they will find each other again.
Hope this helps,

I updated from windows xp to windows 7 and can not get into my itunes account. I get the notice that I am only allowed 5 devices and this isn't a new device just an updated one. How do I get to my itunes?

Take a look at Apple's document for authorizations -> iTunes Store: About authorization and deauthorization.
You can deauthorize all computers from iTunes. All you have to do is click iTunes Store, click your account name in the upper right corner of iTunes, then deauthorize all.

On my iPod touch why does it only allow one earphone to play? I've plugged the ear phone kno another device and they worked perfectly fine what is wrong with my iPod

- Try inserting and removing the headphone plug a dozen or so times.
- Next try a reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod
If you still have the problem that indicates a hardware problem, like a bad headphone jack.

I am trying to synch my iPhone but I am told that I am only allowed 5 devices. Unfortunately I am up to 6 because one of my computers died. Can you assist? Thank you

I am trying to synch my iPhone to my new MacBook Pro but I am told that I am only allowed 5 devices for synching. Unfortunately I am up to 6 because one of my computer's died from a hard drive disease. So I am actually only wanting to synch with 5 devices. Can you assist? Thank you.
I am using OS10.8.2

Thanks snozdop for your help but there is a problem. With deauthorising the instruction says "Also, make sure you deauthorize your computer before you upgrade your RAM, hard disk or other system components, or reinstall Windows. If you do not deauthorize your computer before you upgrade these components, one computer may use multiple authorizations." I did not / could not deauthorise before upgrading from my broken hard drive. Thus I remain unsure how to proceed.

Time Capsule only allows one Macbook be on the internet at a time!

So far no one even at Apple Care has been able to solve this problem.
My wife and i have brand new Macbooks. Mine, the latest 2.4Ghz black model bought in the UK and her's the 2.1Ghz bought in the US.
We both used the Orange livebox as our wireless router and it worked seamlessly (albeit only when security was turned off) until i purchased a 1TB Time Capsule.
I managed to get the TC up as our wireless router with the Livebox as the modem, but, bizarrely, it will only allow ONE computer to be on the internet at a time - and giving preference to mine. Basically, the second i turn my airport on - she loses connection! It's like my computer ***** the internet away from hers.
If hers is the only computer on in the house then it works perfectly.
I have spent hours on the phone to Apple Care and changed a number of the settings within Airport Utility, but the longest we got both computer running on the internet together was for about 20 minutes when i switched to Radio Mode 802.11n only (5 Ghz). For a moment we thought the problem was solved until i put the phone down and low an behold, she lost her connection once more.
Any suggestions?
Thanks in advance.

Don't know what an Orange livebox is, but I will treat it as a DSL modem and assume the ISP uses a DHCP server. Make sure you have connected the modem to the TC WAN port.
Open AirPort Utility, select the TC, click on Manual Setup, click on the Internet tab.
- is 'Connect Using:' set to 'Ethernet' - set to this if not.
- is 'Configure IPv4:' set to 'Using DHCP' - set to this if not.
- is 'Ethernet WAN Port:' set to 'Automatic (Default)' - set to this if not.
- is 'Connection Sharing:' set to 'Share a public IP address' - set to this if not (if set to Bridge Mode then only one computer will be able to use the internet).
Click 'Update and wait for TC to restart.
Check the network settings on the client computers. Go to System Preferences/Network/AirPort:
- click on the 'Network Name:' roll-button, select 'Join Other Network...', enter 'Network Name and select the security type you are using, and finally, enter your Password and click 'Join'.
If ISP uses DHCP:
- click on 'Advanced', TCP/IP and confirm that 'Configure IPv4:' is set to 'Using DHCP', click 'OK'.
- click the 'Apply' button and exit System Preferences.
May also be wise to Repair Permissions using Disk Utility and to reboot your network hardware:
1. Turn power off to ISP modem and the TC, and shutdown computer - leave power off for 10 minutes.
2. Turn on modem and wait for it to complete its test cycle. Then turn on the TC.
3. Turn on computer and check your internet connection.

Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times

Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times.
Please help to set it up, thanks in advance

You need to give more info..
Firstly only works for what.. networking.. backup.. wireless. You need more nouns.. more adjectives... describe what you want and what fails.. then we can figure out why.
Most likely you have bridged it when it should be in router mode..
Most likely you are using Lion or ML which has the airport utility bridge the TC by default.
Change it to working as a router. That might help.
If you press reset button it will default back to router btw.
If you are on Lion.. use a real utility. http://support.apple.com/kb/DL1547

What are the limitations of AMS5 only allowing one-way broadcast for the video capture support?

I am interested in a tool that can access a clients webcam and begin recording from their device. When the time is up, it should store that recorded video to a server. Then, of course, the files can be accessed. Streaming is of less significance than simply capturing and accessing video from a client
Can I do this with only Adobe Media Server Standard Edition?
Bearing in mind, I may need to be capturing video from multiple clients at one time. Is this limited by the fact that Standard only allows "one-way broadcasts?"
Thanks,
Carl

Thanks for the suggestions. I've tried using DVCPRO HD in the past, but the picture quality of the captured screen footage turns out blurry. The only codecs I've found that provide a perfectly clear image are H264, Animation and Uncompressed 8-bit. The problem with the latter two is that video files lasting only a few seconds measure in the 100s of MBs. Working with files that large would slow my editing and rendering down to a non-workable length.
I just don't understand why I can't edit H264 video if my sequence codec is set to H264. The 'Codec error' I get is baffling.
