Airport Extreme has stopped doing DHCP

I have been really happy with my Airport Extreme N until lately, it seems to be flaking out on getting an address from the Cable Modem. My setup is Cable to the modem, modem to an ethernet hub that goes all over my house, the Airport Ex is plugged into an ethernet jack in one of the rooms, it has been working fine... Until recently. I unplugged the ethernet cable from the back of the Airport Ex and plugged it directly into my MacBook Pro. No problem. Immediate connection. So it is the stinkin Airport giving up the ghost?

The AEBS is like any other piece of equipment - it can die - but it can also get 'confused'. Try two things before assuming there's a hardware issue. First, power it off and let it sit for a good 10-15 seconds before plugging it back in. A simple restart can fix a multitude of problems. If this doesn't work, perform a reset. Since the reset will return the AEBS back to factory defaults you might want to open the Airport Utility and make a note of your settings before you do this.

After 7 months of flawless performance, my allpe airport extreme wi-fi stopped working for my iphone and ipad. I am not very computer savey. Can someome help me?
Thank you,

Do you mean that only your iPhone and iPad stopped working! while other devices (Pc, laptop, etc..) still works?

How do I get my airport extreme to stop recycling? Using OSX 10.7.4, Airport Utility 6.1

How do I get my Airport Extreme to stop recycling? I'm using OSX 10.7.4 and Airport Utility 6.1.

The Airport Extreme is putting out the signal OK. Gan use my iPod no prob. The Mac goes from 'On' to 'looking for networks' back and forth all the time.
As Apple has said the AirPort Extreme is functioning correctly if other devices can connect. You have a Mac issue, so that is really a question for the support area for your Mac.
I suggest that you try one of these general areas, then pick out the specific model that you have:

My Airport Extreme just stopped working. The message says ethernet cable not plugged in, but it is. Cable modem works fine. Is this a common problem?

My 2-year-old Airport Extreme instantly stopped working last night and is flashing the status light. The problem description is that the ethernet cable is not plugged in... however, the ethernet cable is still plugged into the cable modem. I checked the modem by plugging directly into my laptop... it works fine. Is this a common problem? Is there anything I can try other than sending it in for warranty repair?

At this point, before sending it back, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

Airport Express has stopped working, no IP-adress

Airport Express has stopped working. In my Airport tool, I can't see the Airport Express anymore.
Under network, I can still see the Airport, but it says, that it cant find an IP-Adress.
It can see my Airport Extreme.
Thanks in advance.

Try resetting the Airport Express.
If you don't see it in Airport Utility in your Utilities folder, then you would need to reset it...
Do you have it set to "Join" the Extreme network? or something else?
See this Apple doc on how to reset your base station.
http://support.apple.com/kb/HT3728
Also, you would not see it in your Network preference panel in the System Preferences.
You will only see the main network which is your Airport Extreme....
Unless you have 2 separate networks....
How many do you have?

I have a iMac with a built in airport extreme card. Does the imac act as a wireless router so that I can connect to the internet from my iPad by tethering through my iMac?

Depends which iMac exactly and your network setup, you can go into System Preferences and under the Sharing pane you can enable internet sharing from ethernet (or whereever you get your internet from) to Wi-Fi.

My airport extreme has connected to a Tplink router, i set my AE in Create network, so i get a problem of Double NAT. How can i repair this probleme because i have to use TPlink for my IP TV and i want to use AE to creat my network and the guest NW.

No, not unless it is simply a network connection.
How is your IPTV being provided.. if it is using a separate vlan or separate vpi/vci in the adsl connection. Who is your ISP?
Is the TP-Link ADSL?
Is the IPTV using a separate voice channel on adsl?
Or a different vlan.
Sorry but it is something where a definite answer is not possible unless you provide all the details.
The setups are unique to each ISP around the world..
Here is one for our local ISP.
http://www.avenard.org/iptv/Setup.html
He has a section on getting this working with apple router over wireless.. look
http://www.avenard.org/iptv/IPTV_and_Wireless.html
Google around and see if other people have had success.. the whole setup is tricky.. and it is hard if nobody has used it who actually understands networking.

We recently switched ISPs. To connect to the new ISP our Airport Extreme has to be in bridge mode. Now our Nintendo Wii won't connect to the Airport. Is it an issue with bridge mode that is causing this?

We recently switched ISPs. To connect to the new ISP our Airport Extreme has to be in bridge mode. Now our Nintendo Wii won't connect to the Airport. Is it an issue with bridge mode that is causing this? We're running two Macs wirelessly with no problems. And the Wii did connect before the switch.

Hello and thanks for the reply. I gave this a try, turned off Airport on one of the computers and tried the Wii again. Still no connection. I should say that we're also running an old G4 (wired) off the Airport as well, with no problems. I've tried many things to make the Wii to work, including power cycling the Airport, turning off the security settings in the Airport, resetting the Airport to it's default and redoing the network, resetting the network setting on the Wii (several times), moved the Airport closer to the Wii, all with no luck. The Wii "sees" the Airport but won't connect to it. I'm at a loss for anything else to try, so any help is appreciated.

Are we able to use the AirPort Extreme has a wifi extender

are we able to use the AirPort Extreme has a wifi extender

Yes, if you plan to extend using wireless only and you use it with another Apple wireless router....an AirPort Express, Time Capsule, or another AirPort Extreme.
The AirPort Extreme will need to be located where it can receive a strong wireless signal from the "main" AirPort, as the "extender" can only extend the quality of signal that it receives.

Wired connection to cable modem. Airport extreme has to connect to internet if computer goes to screen saver. Any way around this?

Describe the issue in more detail.. as it doesn't currently make sense.. the AE should always be connected to the internet. It should never disconnect.. but the computer can fail to connect to wireless after sleep.. that is common problem.
See Tesserax docos if you have wireless connect issues after sleep.

Since the Airport Extreme has a type of WPS

Since the Airport Extreme has a type of WPS (clients can connect with a PIN instead of password), it would be good to have a statement from Apple that it is or is not subject to the same recent successful attack on WPS as other home office wireless access points. http://www.kb.cert.org/vuls/id/723755

Current model Airport Extreme no longer accepting DHCP WAN assignment

I woke up to my airport extreme not connecting to my ISP.
I'm using DHCP on the WAN side, and my Airport can no longer retrieve a DHCP address. It appears the Airport does find the ISP's router address (the router address and subnet mask are populated), and my ISP sees the DHCP request. However, my Airport will not accept the DHCP response and assign the address. (My Internet connection is over a fiber line and I use a "portal" for access. As such the ISP can see any and all packets for troubleshooting.)
I purchased my Airport new in November, 2011.
If I connect my Macbook Pro directly to the portal, I get a new address off the ISP.
My ISP then created a DHCP reservation. Still no luck. I then tried assigning a static address. That works as well.
So it seems my router is not accepting the DCHP response or assigning the address. My ISP uses DHCP3 on Linux.
Any ideas?

So it seems my router is not accepting the DCHP response or assigning the address. My ISP uses DHCP3 on Linux.
I'm not aware of any incompatibilities with version 3 of the DHCP service that would cause your AirPort not to accept an IP address from your ISP ... although anything is possible. Is this something that your ISP has just updated their DHCP services to or has this been their configuration for a while?

My airport extreme has to be restarted to allow a new device to connect. How do I get it to connect automatically?

My airport Extreme will not allow new devices to join automatically. I have to restart it every time someone visits. Does anyone know how to get it to see new devices automatically?

In its default configuration, the AirPort Extreme Base Station (AEBS) has its DHCP Server service enabled which would "listen" for requests from network clients that have the counterpart DHCP Client enabled (this would be the clients' default as well).
It sounds like something is amiss with the DHCP Server service on your AEBS. I would recommend performing a "hard" reset on the AEBS to see if this resolves the problem.

Airport extreme has self assigned ip... on all my apple devices

Man oh man... this issue has been festering for almost an entire year now and I have not found a solution. Last August (2009) my macbook stopped wirelessly connecting to my ATT 2WIRE dsl modem saying it had a self assigned ip address. I bought the computer in July and could connect with no issues for about a month. Ever since then, I've been connected via ethernet with slow connection. At the same time, the 2 iPhones in our household also could not connect wirelessly. One G5 could connect wirelessly but was extremely weak and often dropped the signal.
I did tons of research and found zillions of other people with this issue and no resolution. I've tried every solution on macrumors, and apple discussions with no results... I've disabled firewall, renewed DHCP, tried DHCP manual (which then changes the status to say I'm connected, but nothing works in my browser), restarted, etc. At work, I can connect to our Linksys router wirelessly with no issues.
Originally I thought the issue was my modem so I ordered another one. Same issue. Just this week I was at my wits end and cancelled my service with ATT and switched to Clear. I acquired a Linksys router to connect to the Clear Modem and I'm STILL having this issue. The difference is now that my iPhone can connect wirelessly but my macbook still cannot. The router is a Linksys WRT51ab. My macbook pro is on version 10.5.8. I can only assume that some kind of update to airport is causing the problem. As of now, my IPv4 address is: 169.254.111.225
Please someone help me! I promise some kind of reward if you can help me fix this.

Welcome to Apple's discussion groups.
The "AirPort Extreme" in this board area actually refers to Apple's "AirPort Extreme Base Station". It doesn't seem that you have such a thing. Please confirm that. The best place for similar posts is probably the "Getting Online and Networking" forum (http://discussions.apple.com/forum.jspa?forumID=1222) of the "OS X v10.5 Leopard" area.
To address your problem, you might try resetting your connection settings using the steps listed in this message:

They're not guaranteed to solve the problem, but they'll only take you a minute or so to try.

Airport Extreme Not Consistently Assigning DHCP

I am using a relatively new (within the last year) Airport Extreme as the primary router on my home network. Connected directly to the router is a GigE switch, an AT&T Microcell, and another router - an Aruba RAP which creates a secure VPN for my home/remote office network. The connection to my Apple desktop is made through the GigE switch, as are three additional wired connections to other devices in my home, including two Apple TV's and (hopefully) two Airport Expresses.
I recently discovered when trying to configure a new Airport Express to extend my wireless network over ethernet (roaiming network) that my Airport extreme is not consistently assigning the IP addresses within it's defined DHCP range (10.0.1.0 - 10.0.1.200). About half of the time devices on the network are getting a default 169.254.x.x IP address, which (in the case of my desktop) results in an 'self assigned IP' error within the network settings. I can reboot my apple desktop and the next time it gets a correct 10.0.1.1 address. Reboot again, it defaults back to a 169 address - and so on. It doesnt seem to make any difference if I connect my desktop directly to the Extreme, or, if I connect it through the GigE switch. And, every time I get a 'self assigned IP' I have no connectivity beyond the Extreme (no internet), and I'm forced to use my wireless/Airport connection.
Another problem here is that the Expresses both expect to receive 10.x IP addresses and when they don't get one, they basically become pretty $100 paperweights when connected over ethernet. Also, if you try to configure a new Express without the 10.x address it expects to be assigned (and defaults to a 169.x), the Airport Utility will no longer 'find' the Express once the Express auto-restarts and the update will fail. I learned this after spending two hours on the phone with Apple support yesterday - during which they were able to get my first generation Express configured, but, not my 24-hour old second Generation Express, which continues to act only as a paperweight. Oddly enough, everything works perfectly well if I use only wireless connections to the Extreme - there are no IP problems and everything works correctly. Unfortunately, I want to use wired connections for all my devices (expresses, Apple TV's) because we stream alot of audio and video.
Is my Extreme not working correctly? Does anyone think it's problematic to have a second router (the Aruba) connected behind the Extreme? I suppose I could force some components to use only specific IP's, but, that sounds like a pain. If the Aruba is problematic, I would also consider a second internet connection, or, finding some way to split home IP traffic vs work IP traffic.
Thoughts?

I've been doing some research and it appears the 'self assigned IP' address is a common problem in the Apple support community. And, for what it's worth, it appears an inability to isolate or accurately troubleshoot the problem - by users or Apple tech support - is a recurring theme. I totally understand that no two home networks are exactly alike (different ISPs, switches, configurations, etc.), but, after being a die-hard PC user for my entire life I can honestly say I never encountered anything like this while using my PC. I'm not about to trash my Mac, but, the Apple 'ease of use' selling point is quickly losing it's lustre.
I got into this mess because I added a GigE switch to my network. Rather than buy a different switch (a tactic which assumes my problems are being caused by the switch) I'm inclined to buy another Airport Extreme and try daisy-chaining them together to overcome the reason I bought the GigE switch in the first place, which is not enough ethernet ports on the Extreme. That, or I'll spend a weekend in my attic re-wiring my home network to daisy-chain my two Express devices together instead of requiring individual connections to my router. My experience with Apple hardware thus far is that it prefers to 'play nice' with other Apple hardware over non-Apple hardware. It could be $100 error on my end (or, a weekend of not doing yardwork), but, I think it's the best shot. Other possible fixes, including manually assigned IP-addresses, put too much emphasis on software and network configuration - which (by my non-scentific analysis), are two areas even harder to troubleshoot.
I'll let you know how it goes.
Mh
Post Script - Dear Apple: please find a way to significantly increase the number of ethernet ports on your Airport Extreme Router. Thank you.
