Airport Extreme 'sees' only one computer at a time

Just ought a new Airport Extreme to replace on old Airport Express (flying saucer type) and find that only one computer can access the internet at a time. This is a downgrade odf service from the old Airport Express, and we cannot find any method to fix the problem. Until we solve the computer problem, we cannot go on to figuring out how to connect our iPod Touches and iPhone. All our equipment is Apple, except for the DSL modem supplied by Earthlink. Anyone have any ideas? Earthlink said that there equipment is working properly, and we beliee that because the old system still works perfectly.

No. Something else is going on.
Your son may be hogging all the bandwidth but your wireless network should never simply disappear. Moreover, if your son isn't doing anything the available bandwidth for other devices should remain unaffected.
I suspect that something is miswired, and from what you describe I suspect that link is between the Extreme and the "other computer".
The way to accomplish what you propose is
Modem > Ethernet cable to Extreme's WAN port
Extreme's LAN ports > wired Ethernet devices.
There should be nothing but an Ethernet cable linking an Extreme LAN port and any other wired device. If you run out of available LAN ports on the Extreme, you need to by an "Ethernet switch" - they are not expensive, but don't call it a "splitter" or you will only confuse yourself. The switch would be connected to one of the Extreme's LAN ports, and you would connect additional devices to it. You can also use one of your Expresses for that purpose, assuming it is the current generation model with two Ethernet ports.

Only one computer at a time??

I have a Airport Express setting up a wireless network in the place I'm staying at, and can successfully connect with my iPhone, and MacBook.. but when my wife tries to connect with her Windows Vista laptop, she can not get past the local network to the internet. If I turn off the Macbook, she can then connect, but I cant... It seems that only one computer can connect at one time... is this right? is there a way to change that?
The settings of the AE says that there are 3 connections to it (my Laptop, her laptop and my iPhone). I' have tried changing and even turning off all securities on the AE. And help is GREATLY appreciated.
Thanks.

I believe I read somewhere that the AX limit is ten.
It could be that the LAN it is connected to (I assume that's how you have it connected to the internet) only allows two computers per node -- and the iPhone counts as a computer.
Try turning off Wi-Fi on the iPhone. Will both computers connect then? Since you can't use Wi-Fi for iPhone phone calls, that seems the most expendable of the three devices in the wireless network.

Airport allows access to only one computer at a time

Is there a setting which prevents internet access by more than 1 computer at a time via airport? I cannot get laptops to connect simultaneously (via airport) to the internet

If both NAT & DHCP are both enabled (the default) on the AirPort, and each of the computers are configured as DHCP clients, then they should all be able to access the Internet through the AirPort simultaneously.
To verify that both NAT & DHCP are enabled, check that Connection Sharing = Share a public IP address. (ref: AirPort Utility > Manual Setup > Internet > Internet Connection > Connection Sharing)

Only One Computer at a Time on Internet

I have a cable modem (motorola) and using airport as my wireless router connected to my iMac. I have a MacBook and an iMac. Unfortunately, only one of us can be accessing the internet at a time. This was not the case before. If one of us is already online, the other just "times out" and cannot access the net. Is there setting I need to change in order to having us accessing the net at the same time? Thanks for any help you can provide.

1 - is everything set up to use DHCP - if you have any static IP addressing you may have problems like this
2 - restart everything - shut everything down including the Cable modem (unplug it) and the airport router and both computers
3 - plug the power to the cable modem and wait 30 seconds then restart the Airport router - after everything is up an running (probably another 30 to 45 seconds but watch the lights - when the cable modem in indicating LAN traffic you are up - then turn each computer on - either log into the airport router and look at the DHCP table and verify that both computers are there and have their own ip addresses or look at the network preference on each an verify that they have different ip addresses
If this does not correct the situation set your airport router to use the Open DNS servers for DNS - 208.67.222.222 and 208.67.220.220 (I have to do that on COX to have Leopard happy)

No Internet acces or only one computer at the time

Hi everybody,
I'm a freelance IT supported and I'm new to Apple. I studied and always worked with PC but with people having more and more Mac at home I had to adapte.
I have a problem at a customer's place which is kinda hard to explain. I'm unable to get Internet access on any devices connected to the WIFI. I tryed sevral setup and the best I can get is "one-device-at-the-time" (the last device that connects to the WIFI). I did screen captures of this setup.
The setup isD-Link DSL-320B Modem (set as DHCP) --> AirPort Extreme (WAN Port) --> wireless devices (iMac, iPad, iPhone, PC, etc.)
Unfortunatly, all the screen captures are in French (I'm in Switzerland) but since it's not literature, I think you can all get what's writen bellow.
mode pont = bridge mode (I think this is how I actualy got one computer to access the web)
I don't understand why the address is 169.254.xx.xx. Shouldn't it get a 192.168.1.x since the D-Link is setup as DHCP (see next screen capt) ? The DNS servers are the ones provided on the ISP info sheet but I don't think it's necessary to put them here, right ?
strangely, the IP range didn't show up when I did the screen capture but it's 192.168.1.2 to 192.168.1.254
I spent two unsuccessful hours last time, i'd realy like to make it right next time so I can actualy send them an invoice and eat more than pastas ;-)
thanks for your help,
Julien

Hiya.. thanks for the lovely screen shots.. this is hard and would be impossible without them.
Something odd is happening... I don't see anything wrong with your setup.
What I do see is dlink doing its dinky toy dlink type stuff.
The AE should have got an IP from the dlink. 192.168.1.x and as you have it bridged it should also pass packets to the dlink which would get IP for the wireless.. nothing wrong in any of that.
It is failing .. and obviously not passing packets correctly on the ethernet link to the Dlink.
DHCP discovery at the very least is failing..
Look at your last screenshot of the dlink setup. Look at the IP handed to the AE. 83.79.62.39
Where did that come from.. it says the AE is a client but the IP is some odd thing.
Now did you happen to set the AE in DMZ of the dlink or did you use some other method to try and force this to work.. at some point it is passing .. perhaps an old public IP to the AE.. which is not correct.
Your tech-it-easy computer plugged into the dlink is getting the correct LAN ip 192.168.1.2 clearly the AE has failed.
I recommend you reset the Dlink to factory and redo the setup.
If the ISP uses PPPoE, then setup the dlink in bridge mode and run the PPPoE client on the AE.. this is the best method.. but PPPoE is seldom used in Europe for whatever reason.
If you use pppoa or ipoa or other dsl authentication then you must keep using the AE in bridge.
Go back to the fundamental problem.. it is not passing packets over ethernet correctly. The AE is gigabit unless it is very old. Dlink I am guessing is 100mbit. There are occasional hitches.. if you have a switch 10/100 drag it along with you and plug it between the dlink and the AE.. and see if it then gets IP correctly. Check with another ethernet cord.. all the stuff you know.
In the AE you can set wan port speed.. but you will need the AE in router mode.. ie it is NATting a public IP, but you will get double NAT.. as a test you can go for that.
Use 100mbps full duplex.
Of course you don't want to double NAT permanently.
If you don't make progress.. post again..
There is a manual way of bridging the AE.. we normally call it wan bypass.
It is complicated so try the above before you do that.
BTW,,, when the one computer does work, check what IP it is getting.. is it 83.79.62.39.. or whatever the public IP. If so the AE is definitely set wrongly in the DMZ of the dlink.

Only one computer at a time through the router WRT 110

We have a Compaq laptop (Vista) with built-in wireless that connects through the router just fine. We have a new HP desktop (Vista) with a Linksys wireless card that connects through the router just fine. When either is connected the signal strength is excellent. But if we try to connect either machine while the other is already online, it will not connect and it disconnects the first machine. We have to shut both machines down, shut off the router for 30 seconds, restart the router, restart the desktop, and restart the laptop. Usually (but not always) both machines will then go online. Everybody's happy unless one of the machines goes to sleep. If you then "wake up" that machine, you have to start the whole process over again. I have tried several times to set up the router with a wired connection, I have set up both machines numerous times, transferring the settings for the network back and forth. I have tried setting up a new network. Most of the things work until one of the machines is shut down and then started again. I know it has to be in the router settings but I don't know where to go to solve this. Driving me batty, going in circles.....HELP!!!

Try to readjust the wireless settings of your router :
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WEP, Encryption should be 64 bit.Leave the passphrase blank, don't type in anything...Under WEP Key 1 type in any 10 numbers please(numbers only and no letters eg: your 10 digit phone number) and click on save settings...
Please make a note of WEP Key 1 as this is the Security Key for the Wireless Network...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

Can use the internet but only one computer at a time...

I have a very old PC with no ethernet ports and i have one macbook pro. I just bought an airport base station and have connected it to my modem via an ethernet cable, and the modem is then connected to my PC via USB.
This set up allows me to connect wirelessly with my macbook pro, but if i want to connect to the net via my PC it won't let me...unless i turn off the base station and then reboot the modem. but now i can't connect wirelessly.
Apple guys say, because I'm not connected directly to the PC from the base station (due to no ethernet ports) I'll never get round this problem. Before I give up, is there any thoughts on how i can resolve this catch 22?
Macbook Pro Mac OS X (10.4.6)

When I encountered the same problem a while back, I discovered that I had mistakenly connected the ethernet cable from my modem into one of the <-----> (ethernet) port on the back of my Airport instead of the O (WAN) port.
It belongs in the O port.
I hope your problem is this simple to solve.

AP Extreme only letting on one computer at a time

My wife recently got a MacBook instead of her old HP laptop, and we got the AP Extreme base station so we could share our laser printer. However, I have yet to be able to have both computers on the network at once. If one is online, the other one can't load any sites. I'm assuming it's got something to do with me cocking up the DHCP settings.
Cable modem: RCA DCM425
Macbook 1 is 4 years old, running 10.4.7. (Currently online).
Macbook 2 is 4 weeks old, running 10.6.4. (Currently not online, though that's the one that's got the Airport utility to control the base station; ethernet cable is plugged into the base station).
Also connected to the network is a TiVo - it's recognizing the network but not getting online successfully.
When I set up the base station, if I try to have it get ipv4 info via DHCP, nothing works. If I put in an IP address, subnet mask, and router address manually, I get the current fiasco. I strongly suspect this is the source of my problems, but am in wAAAAy above my paygrade on these things. Any suggestions?
This morning, I unplugged everything and let it sit for a half-hour, then plugged everything back in. This had the salutary effect of making my computer, rather than my wife's, be the one that's got the live connection.
P.S. Less likely cause of problems that I'll mention for full disclosure - I named the new wireless network the same thing as my old network was called. Old Linksys router is currently sitting on the floor, not plugged in (power or network), so I don't think that's it.
Thank you in advance to anyone who takes the time to write back!

When only one computer can gain Internet access is typically a symptom that the router is either not "recognized" by the modem or that it is not properly configured to share the Public IP address provided it by your ISP.
At this point, I would recommend a "factory default" reset on the AEBSn to get it back to its "out-of-the-box" configuration to see if this will get the communications working properly again. If it does, we can go over the set up steps to meet any of your networking requirements. Once reset, the AEBSn will be providing basic Internet routing capability and provide an unsecured wireless network with a name like: Apple Network NNNNNN.

They said I need to change my settings to NAT settings. I haven't been able to figure out or find anything. I have also spoken to Apple Support on the phone for hours without being able to figure out how to do this ( i don't think he knew much either lol.) Please help me because I've got about 15-20 devices in my house that require to be connected to the internet and this is just making things ridiculously slow and painful for me.
Thanks!

It is on DHCP & NAT under router mode yet my isp is still the one issuing ip addresses to my devices instead of the router issuing them

Is it possible to have Time Machine backUp computer HD AND external HD connected to Airport Extreme.
Sorry, but no.
Time Machine will backup your Mac, but not the hard drive attached to the AirPort Extreme.
Time Machine will back up a hard drive only if it is attached directly to your Mac via USB or FireWire.

I can't see hard drive attached to Airport extreme from Windows XP computer

I have a Windows XP computer on my network. I can no longer see the network hard drive attached to Airport Extreme from the XP computer. I can see it with all the MACs on my network and all the Windows 7 computers. I can connect to the internet with the Windows XP computer. I previously had no problem seeing the network hard drive attached to the airport extreme from the XP computer and one day it just disappeared. I have deleted and reinstalled Bonjour, not just Bonjour print services. I can print to a network printer that is not attached to the Airport Extreme. Help!

Well, I'm stumped. I spent an hour on the phone with Apple support-- they ran through the scenarios I had already been through, and they came up with nothing useful. I ended up taking a second 160gb HD that was formatted NTFS, and formatted if for HFS+. This drive was visible through Finder. I took the same drive, formatted it for FAT32 and, surprise, surprise, NOTHING VISIBLE.
The "just works" philosophy is OK, but it's bunk when it comes to network drive support. I'm doubting the wisdom of this purchase now.
$2500 for a computer that can't connect to a network drive that can be seen by an $500 Dell laptop?
The issue simply seems to be this: put a FAT32 drive on another box, and it can be shared by Macs and Windows boxes.
Put that same FAT32 box on an AirPort Express, and my Mac is BLIND. It can't see the drive.

I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too..

I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too. Any ideas? I'm guessing the only way is to do what I've seen in these community pages which states that it can be done but it will drop the bandwidth by 50%. Thoughts?? Thanks!

The Cisco/Linksys WRT-54G was one of the very few routers said to be compatible with Apple's implementation of WDS (Wireless Distribution System) settings.
The info that I have on file indicates that only the WRT-54G versions 4 and under were compatible, so that would be one bridge to cross.
Even if you find that your Cisco/Linksys might be the right version, Apple never published instructions on how to configure the Express devices with other manufactures, so users were left to their own devices to try to figure out how to get things working. Apple's instructions to connect to other Apple devices are in the link below:
WDS network
If you were hoping to use 2 Express devices in this type of configuration...even if it works...the bandwidth penalties will be extremely severe.
The first Express drops the bandwidth (and speed) on the entire network in half and the second halves everything again. So, the result, in effect would be a "g" wireless network running at 25% speed. Few users would consider installing this type of network.
At this point, it becomes one of those things where the fact that you might be able to do something does not mean that there would be much value in doing so. But, it is your decision to decide if you want to try to proceed.

AE: only one computer connecting to network

We recently moved back from Northern Japan where I originally had the network settings programed. Yes, it is an American spec product, I bought it on Post.
So when we finally moved to the states I tried to reset to the factory settings with no joy. It was a chore just to get my network reconfigured on just one computer. Every time I reset the settings to factory, it still had its name and all the settings in place.
the problem is that i cannot connect one more than one computer. can anybody help??
i have a MacBook Pro that the wireless is actually working on but the desktop Mac computer which is inches away from the AE is not able to get on the internet.
HELP??

It could be a combination of things. Try the following
Complete reset of your cable modem (when you say modem, I am understanding that this is a simple modem with one ethernet port, correct?)
Push the reset button on the modem
Power it off
Pull the battery if it is easily accessible
Leave it off 30 minutes
Power off everything else, AirPOrt Express, computers, etc.
Connect the modem to your AirPort Extpress with the ethernet cable
Power up the modem only and let it run 3-4 minutes by itself
Power up the Express the same way
Power up your computers the same way
Check to see if multiple devices can connect.
If no, open AirPort Utility - click Manual Setup
Click the Internet icon
Make sure that the settings for Connection Sharing is set to Share a public IP address (if you have a simple one port cable modem).

The computer that I had my iphone apps synced to has died and I don't know how to get access to my apps on the new computer. I'm using a Windows pc. I understand that I can only have my apps synced to one computer at a time, but the former pc is dead.

My HP Touchsmart died the other day. My husband works on computers as a hobby and was able to get me up and running on a Dell laptop in no time. I have an iPhone 4s and had all my apps on itunes on my HP. I understand that you can only have your iPhone apps synced to one computer at a time, but what do you do when the computer containing all your info is in unusable condition? I have tried deauthorizing all the computers associated with my account, that did not work. I had this problem once before and finally ( after much blood sweat and tears ) was able to deauthorize the old computer, but it was in working order. Two of the computers that are listed under the iTunes Wi-Fi Sync setting are no longer in use, the HP had my apps synced to it and the other had everything else except my photos, which are on a third computer that is still in use. Please forgive for information overload but am trying to give all the info that I think could be relevant. Your help would be appreciated so much!
Sincerely,
PiPI

If you really want help, stop messing with the fonts and post so that others can read and offer suggestions.
Or better yet... try a search, I'm certain you'll find a solution to whatever issue you're experiencing.
I have found that many times it is the things that make you most angry that push you to action. This was the case here. Thank you for causing me to get so angry that I found the answer myself.

Can only connect to Internet from one computer at a time on network

I have a 2 computer network in my office networked with an Asante 10/100 hub. The computers are a iMac 24 (Intel) and an old G4 (PCI). The network has worked fine until just recently. Now, I can only connect to the Internet with one computer at a time...(DSL connection). I checked cables, ports, etc, and I'm wondering if this is a 10.4.9 issue. Coincidentally, I noticed that I am not able to access the Internet via Win XP using Parallels which also worked fine up until recently. I checked with the ISP (AT&T) who confirmed that all is OK on their end. Anyone have similar problem? Could OS X 10.4.9 be the culprit? Any help on this will be much appreciated. Thanks.
iMac 24 Mac OS X (10.4.9) 2G RAM; NVIDIA GeForce 7600 GT 256

I'd consider that a 3 computer network, Parallels being a virtual machine would alias the ethernet interface and need its own IP address. That may or may not have anything to do with your problem. Actually, the way you've described things, it sounds like a lot has to do with your contract with ATT. Is there a routing device at your end?
The only way 10.4.9 could be the culprit would be if it were the routing device.
