AirPort Extreme splits or multiplies internet source?

Lets assume that my AirPort Extreme (n) was connected
to a 2mbps effective DSL modem, and 4 devices were
wired/wirelessly connected to my AirPort.
Would each device receive 512kbps of internet (i.e.
the AirPort splits the internet source of 2 mbps four
ways) OR would each device receive the full 2mbps
(i.e. the AirPort supplies 2mbps to each device)?
You can't get bandwidth out of thin air. The 2Mbps gets "split" among all connected devices. Not all of them get the same: one may get 128kbps, another one may be 512Kbps, another one may get 700Kbps, but the combined total will ever exceed 2 Mbps.
What I'm trying to get at here is whether the AirPort
Extreme (n) acts as a Router or as a Switch in
relation to the internet supply?
The AEBSn performs as a "router" with NAT and DHCP.

Connects to Airport extreme but not to internet

Whenever I close my laptop and reopen, I lose internet connection thru the airport extreme and I won't get it back. It seems that I will have connection to the Airport Extreme, but not the internet.
Sometimes what fixes it is turning the airport off and then on again (sometimes multiple times). Usually restarting the computer fixes it (but not always).
What happens is this (viewing Sysprefs/network/airport/network status and "internet connect"): the internet connect will report connecting...then will announce "connected", but show no "time elapsed" at the same time the Net status will read "airport is connected to ..network...with it's own IP address and may or may not be connected to the internet" And I won't be.
Then, when it starts working again (after the abovementioned turning off/on) it will start counting time elapsed, then in Net Status it will say "airport connected to ..network. you are connected to the internet via airport."
Also, whenever I use "internet connect" to turn the airport off, when I turn it back on again I will not have internet access, just the messages I list above. The "strenth meter" will say my signal is good (which it should be) and it says I am connected but doesn't show "elapsed time" nor will I have actual internet access.
Again, restarting the computer will usually work (less often, logging out then back in).
Another strange symptom-- When I hit the "disconnect" button under the airport section of "internet connect" it disconnects, then reconnects immediately. When I hit the disconnect button w/ in the Sysprefs/network/airport...etc, it does nothing but bring to the front window the "internet connect" window. So the only way to "disconnect" is to turn off the airport (which results in the above problem).
Side note--I am in the habit of turning off the airport (not the base, but from the computer) when I don't plan on using it for security-- am I being excessively paranoid? I do have my firewall in operation. Should I just leave it (being the airport) on all the time (in your humble opinion?
Sorry if this makes no sense or rambles, it is now 5:30 am and She Who Must Be Obeyed will be getting up in about an hour wanting to know if I fixed the computer yet. I'm tired.
Thank you in advance.

Help setting up using my airport extreme to share my internet connection

I want to use my built-in airport extreme to share my internet connection with my PS3. I have a verizon aircard and have read on the internet that this can be done (but not necessarily with airport). I turned on internet sharing with airport and my ps3 reads my connection and obtains my ip address, but then it says could not connect to internet due to DNS server error.
Could someone run me down the process step-by-step so I can see what I'm doing wrong? Thanks for your help.
P.S. I have a iMac running on leopard if that matters.

ll959reds, Welcome to the discussion area!
Unfortunately the Internet Sharing provided by OS X does not provide nearly the configuration possibilities as even a very inexpensive wireless router.
Also if the firewall is enabled on the iMac, it applies equally to all ports including the AirPort (wireless) connection to the PS3. Therefore the firewall will block many of the requests from the PS3. To solve this issues, you would either need to disable the iMac's firewall or configure the iMac's firewall to allow connections via the AirPort side.
A much simpler solution is to use a wireless router instead of your iMac to provide the connection for the PS3.

How do I connect Airport Extreme to U-verse Internet Gateway: Motorola Model NVG510

I tried to set up a new network with the Airport Extreme and get no Internet connectivity from the AT&T gateway. The Extreme network sets up fine and I can access it from all my devices, but no Internet.
What am I doing wrong?
Thanks,
Mick Jones

It will only take a minute to check the Ethernet cable. Just connect it from a LAN <-> port on the Uverse gateway to the Ethernet port on a computer. Turn off the wireless on the computer and see if you can get a good Internet connection that way.
If you can, great. You cannot, then you either have a bad Ethernet cable or the port on the gateway may not be working correctly.
Power up the AirPort Extreme for a few minutes
Then, hold in the reset button on the AirPort Extreme for 10-12 seconds and release
Allow a full minute for the AirPort to restart
Connect the Ethernet cable from a LAN <-> port on the Uverse gateway to the WAN "O" port on the AirPort Extreme
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on Other WiFi Devices
Click AirPort Extreme
The utility will open up automatically, take a minute to analyze things, then suggest that the AirPort will be configured to create a new network. The window will look like the example below, except that you will see an AirPort Extreme instead of an AirPort Express.
Network Name......type in a short, simple name that you want to call your wireless network
Base Station Name.....type in a short, simple name that you want to use to identify the AirPort Extreme
Password......type in a password that will be used for both the Base Station and Wireless Network
Verify the password
Click Next
You should have a green light on the AirPort Extreme in a minute or two, and you should be able to log on to the new network and get an Internet connection.

New Airport Extreme, Green Light, No Internet

Trying to get wifi connection so my mom can use her new ipad I bought her for Christmas and so guests can use wifi when they visit. I connected this new airport extreme 802.11n Wi_Fi to their comcast modem. After connecting get green light on airport extreme but now no internet connection on mac desktop computer. Have tried resetting modem, powering off airport and computer... still no internet. Internet works fine using comcast modem but does not connect to internet at all with airport extreme. Help. Extremely frustrated and ready to return this airport extreme.

Welcome to the discussion area!
It's likely not the AirPort Extreme that is causing your issue. It is the cable modem.
Perhaps you were not aware that a cable modem must be completely reset whenever there is a change in the device that the modem is connected to? Your ISP should have made this clear to you. A good reset often takes 30 minutes or more.
Push the reset button on the modem
Power off the modem for 30 minutes
Pull the battery if it's easily accessible
Power down the AirPort Extreme and your computers
After the wait period, power up the modem first and let it run for 3-4 minutes by itself.
Then power up the AirPort Extreme the same way
Then power up your other devices the same way
Please post back on your results.

Just purchased Airport Extreme ac and lost internet connection 3X. Reset to factory settings and worked for 2 days then lost connection and remedied by unplugging power supply. Anyone else having problems?

Just purchased Airport Extreme ac and lost internet connection 3X in less than one week. Fisrt time, reset to factory settings and fixed problem. Has occurred 2 additional times and connection re-established by unplugging AP extreme. Anyone else having these problems? Do I have a bad router? Thanks.

I definitely think this is a Mavericks issue. My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network. No idea how to resolve this, but here is the workaround I'm posting:
I've had the 'network drop' issue with my Airport Extreme for the last 2 months. It reconnects when I pull the ethernet cable and plug it back in. I've tried downgrading the AE firmware, resetting to factory, etc. Nothing worked. I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:
#!/bin/ksh
while true
do
yup=`ping -c1 -t2 www.google.com|grep from`
if [[ -n $yup ]]
     then echo "Internet is connected!"
else
        ifconfig en0 down; ifconfig en0 up
        echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out
fi
sleep 5
clear
done
I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!
Good luck!

Airport Extreme Blinking Amber But Internet Working Fine Multiple Status Messages

I have Airport Extreme 5.6.1. It started blinking amber showing Airport did not have a valid Internet Address. I was concerned about with changing anything if I could still connet. Checked a forum and it suggested to go to sheck status and see the problem. I did and now I have a new mesage. No DNS server address. I am hesitant about doing anything because if I do and lose internet connection I am really up a creek without a paddle.

Just to update. I unplugged my modem for a short time. When it powered up the light was green on my Airport Extreme.

Airport Extreme (time capsule model) internet speed EXTREMELY slow.

Hello, first thank you for any help on this as it is a bit frustrating for me.
I recently noticed my internet speed was running significantly slower on both my MacBook Pro and on my wifes MacBook.
I had my ISP come and check out the problem. They hooked my MacBook Pro directly to the modem and my speed went from under 1 mb to over 5mb.... he then had me hook up directly to the lan port on the airport extreme and my speed was once again back down to the 1 mb range. He concluded that it must be a problem with the speed once it hits the Airport Extreme.
He ended up giving me a different modem, its a 2wire wireless. I have since connected my airport extreme to the new modem and am still pulling down the same speed, but now I have connected directly to the new 2wire wireless modem and am getting my 5 mb speed.
Can anyone give me any help or advice on what I can do with my airport extreme time capsule so that I can get the speed I should be getting from it.
Thanks again.

More information. I have a separate router for ISP connect/DHCP. I only use my Airports to create a WDS and bridge onto my home network. I have never allowed 2.4GHz or 5GHz phones in the house, just to limit interference. I live way out in the country so interference from neighbors is negligible to nonexistent. Speed testing done with Speakeasy.net/speedtest
I moved all the hard wired machines from the TC to my switch. Which will impact the speed of my backups, but it helped with internet throughput for those machines.
Then I split my WiFi into 2 separate nets, each with a connection to my home network switch. I created a b/g network with my ufo Extreme and my Express (NET 1). I left my TC set for n/b/g (NET 2). As long as my MacBook was powered off internet speed were nice and fast. As soon as I turned on my MB the speeds were impacted, not as bad as before.
I then changed NET 2 to be n-only 5GHz and retested. These was a small but noticeable impact for wireless machines but I have concerns because my ISP is wireless and runs at or near 5GHz.
I then changed NET 2 to be n-only 2.4Ghz and retested. Again a small impact for wireless machines whenever my MB was connected to NET 2.
I then had my MB join NET 1 and speeds were nice and fast all around. My solution, shutdown the wireless on my TC and use it as just a network drive while I use my old reliable b/g hardware for WiFi.
Maybe someday this Draft version of 802.11n will be finalized and have no issues.

AirPort Extreme Not Connected to Internet

I have been trying all day to connect a new AirPort Extreme base station. The base station appears to be configured correctly, in that the green indicator light burns solid. But I can't connect to the Comcast Internet: I get an error message that the Ethernet cable is unplugged (it isn't). I've powered down, reset, and restarted the cable modem; and have disconnected and reconnected the power supply to the base station numerous times, but still no Internet. When I reattach the Ethernet cable directly to the Mac everything is fine. I can't tell whether or not the base station is pulling the IP address, etc., from Comcast. Anyway, I'm getting nowhere with this, and would greatly appreciate input from this discussion group. Thanks very much.

Hello driverdude. Welcome to the Apple Discussions!
Although I know you tried multiple resets, please try the following to see if this will get you Internet connectivity with your Comcast modem ...
Try the following, in order, checking for Internet access after each step, or until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Airport Extreme Flashing Amber - but internet connection is OK

I have the current generation of Airport Extreme, which has been working just fine, until tonight. It started flashing amber. My internet connection is OK, and in fact my desktop is connected to the internet thru the Airport Extreme via ethernet cable, so that pathway works (which rules out faulty cable between Airport and modem). But the amber light keeps flashing, and none of my devices that connect via WiFi can connect to the internet (to be clear, they can see my base station, but they cannot connect to the internet. The only device that can connect is my desktop, which again is connected to the base station via ethernet cable). I've done multiple power-cycles, and a hard re-set of the base station, same result. In Airport Utility, the error is "Your Apple Wi-Fi base station does not have a valid IP address", but assuming that this is the correct error (which I am doubting, since I am connected to the internet), there is no way for me to address it.
I have two Airport Express's on this network - needless to say, they are also showing up as problems in Airport Utility since their base station is amber.
BTW - I am running OSX 10.6.8 - OK, I'm a dinosaur. But just in case that was the problem, I tried to address this with the current Airport Utility from my iOS 7 iPad, but still no luck.
Any advice?

Thanks, landrefl. Airport Utility IS telling me that there is an error, and the error is ""Your Apple Wi-Fi base station does not have a valid IP address". But that's my problem - I'm writing this now because I am connected to the internet, through the wired connection thru my Airport Extreme. So, although it is telling me what it thinks is the problem (""Your Apple Wi-Fi base station does not have a valid IP address"), that a) seems to be incorrect, and b) I don't know how I can change or correct it anyway.

Airport Extreme, Network but No Internet

My Airport Extreme was working fine until our cable internet was interrupted overnight. Now I can get wired ethernet when connected directly to the cable modem, I can get a good ip, network and router address to the Airport, even a ping, but no internet to either my wired G5 or wireless MacBook. I've power cycled and fiddled with configurations. Ideas?

Most likely, your AirPort Extreme Base Station (AEBSn) is not getting an IP address from the cable modem.
Although you have tried power recycling, I suggest you give it another go as follows:
o Power-down the modem, AEBSn, and computer(s); wait at least 10-15 minutes.
o Power-up the modem; wait at least 10-15 minutes.
o Power-up the AEBSn; wait at least 5-10 minutes.
o Power-up the computer(s)
Your computer(s) should now be able to access the Internet through the AEBSn. Please post back your results.

Setting up my Airport Extreme properly with multiple routers on a home network

I have a 4 bedroom house that over the years has had router after router added in different rooms. I recently bought an airport extreme and an airport express as I am getting sick of not being able to network everything as well as to have one strong wifi.
So I have set up the Extreme in my office and the express at the far end of the house and it's doing wonders in boosting the wireless signal. This is what I am trying to solve:
How do I make all the wired routers apart of my wired and wireless network? The router/modem that was installed by Verizon obviously should stay. I read in another forum that NAT should be turned on and all other routers shouldn't but would be bridged. I logged into the admin settings for the router and couldn't find any place to change this.
As you can tell, I am no IT. So I am sure this may all be confusing. My ultimate goal is to have a shared hard drive on my airport extreme and shared printer on my express and all computers on the same network, communicating to each other. Currently I have 3 routers + airport extreme and express all connected.
Hope someone has the patients to help me out.
Thanks.

Good diagram!
In that case you definitely want the D-Link to act as a switch, and its manual describes how to do it:
(page 10)
Connect to Another Router
If you are connecting the D-Link router to another router to use as a wireless access point and/or switch, you will have to do the following before connecting the router to your network:
Disable UPnPTM
Disable DHCP
Change the LAN IP address to an available address on your network. The LAN ports on the router cannot accept a DHCP address from your other router.
To connect to another router, please follow the steps below:
Plug the power into the router. Connect one of your computers to the router (LAN port) using an Ethernet cable. Make sure your IP address on the computer is 192.168.0.xxx (where xxx is between 2 and 254). Please see the Networking Basics section for more information. If you need to change the settings, write down your existing settings before making any changes. In most cases, your computer should be set to receive an IP address automatically in which case you will not have to do anything to your computer.
Open a web browser and enter http://192.168.0.1 and press Enter. When the login window appears, set the user name to Admin and leave the password box empty. Click Log In to continue.
Click on Advanced and then click Advanced Network. Uncheck the Enable UPnP checkbox. Click Save Settings to continue.
Click Setup and then click Network Settings. Uncheck the Enable DHCP Server server checkbox. Click Save Settings to continue.
Under Router Settings, enter an available IP address and the subnet mask of your network. Click Save Settings to save your settings. Use this new IP address to access the configuration utility of the router in the future. Close the browser and change your computer’s IP settings back to the original values as in Step 1.
Disconnect the Ethernet cable from the router and reconnect your computer to your network.
Connect an Ethernet cable in one of the LAN ports of the router and connect it to your other router. Do not plug anything into the Internet port of the D-Link router.
You may now use the other 3 LAN ports to connect other Ethernet devices and computers. To configure your wireless network, open a web browser and enter the IP address you assigned to the router. Refer to the Configuration and Wireless Security sections for more information on setting up your wireless network.
While reading the above bear in mind the Verizon box is your router. Don't overlook any of the details in these instructions - read all of it and understand its implications. If I were doing it the first thing I'd want to know is how to reset the DIR-601 to factory defaults since I'd be sure to muck it up about a dozen times before getting it right.
It sounds as though your Express is configured correctly. It is providing a wireless access point for your wired network, the one created by your Verizon router.
The optimal configuration for this design is to configure the Express to create a network using the exact same wireless network name and password as the one created by your Verizon router, otherwise you will have two wireless networks. Leave its "channel" on "automatic" so it won't conflict with whatever the Verizon is using.
It will look a little like this:
I'm assuming some of your devices still need 802.11g so the "radio mode" will most likely need to be b/g compatible.
When everything is up and running, experiment with the wireless transmitter power for the Verizon router as well as the Express. It's best to use the least amount that will work for you, so as not to create needless wireless interference for everyone else. This also minimizes the possibility of people piggybacking on - or trying to hack into - your wireless network.
As far as getting your Windows computer to see your external HD, I haven't a clue. I'm sure it's possible but I'm not a Windows expert.

Can't get Airport Extreme to connect to Internet

I have a D-Link 320T ethernet modem. This works fine connected straight into my Mac, but as soon as its connected to the Airport I loose my internet connection. Its seems to be something to do with my setup, but I'm clueless as to what.
My airport seems to be transmitting something, as my Nintendo DS can pick up the Network name I have created, but it gives me this message "connected to access point, but unable to connect to the server", error code 52100.

Hi Bidge,
Welcome to the Apple.com user discussion boards!
Do you have ADSL? Have you setup the Airport Extreme to establish the PPPoE session with your ISP?
To configure this, please refer to this Apple article - http://docs.info.apple.com/article.html?artnum=166636

Can Airport Extreme connect directly to internet?

Hello, sorry if this has been answered before..
i would like to purchase an Airport Extreme but wondering if this is a router - can i plug my internet directly from phone line into this? or do i still need to purchase a router and plug the airport into that... if so can anybody recommend a good router - i will be on BT ISP in UK. thank you!

In the USA, broadband is dominated by cable using PPPoE and you are right it is common to have an Ethernet modem provided. However the original poster is in the UK and what seems to escape even Apple is that outside the USA things are very different and particularly in the UK with over 80% of broadband users having ADSL. The ADSL is delivered on an ATM network and the providers either offer a very basic USB modem that can not be connected to an Airport or a combined modem/wireless router that makes things messy when you want to use an Airport.
The trouble with using a combined ADSL router is that by default you end up with two routers connected to each other, because both the Airport and the ADSL router are NAT routers. Having two routers connected to each other is far from ideal as things like iChat AV and BAc to my Mac will not work.
You can configure the Airport as a bridge that eliminates the router functions so that the ADSL router is performing the router function and not the Airport. The trouble is the ADSL router does not automatically understand the iChat AV protocol which then involves advanced set-up procedures in the router for port forwarding to get AV working on just a single computer. All this is a bit much for most people to want to be fiddling with.
So the answer is to have an Ethernet ADSL Modem that is not a router. That way the Airport acts as the router and the modem just gives a link to the internet. The Airport being designed by Apple obviously fully understands how to deal with iChat AV so you can have video chats on all your computers without having to fiddle with any complex settings.
The trouble is there are very few Ethernet ADSL Modems and they are not generally sold in shops due to the lack of understanding of the issue by most retailers.
