Airport Express Not Capturing Correct IP Address

I've had my iMac G5 for about 18 months. I access the Internet via a cable modem. Last night I lost the ability to access the Internet.
A Comcast technician walked me thru various steps and determined that my modem and computer were working fine, and that I could connect to the Internet when the modem was directly connected via an Ethernet connection to the computer, minus the Airport Express.
Further diagnosis revealed that when connected to the Airport Express, the computer was receiving an incorrect IP address (10.0.1.2) when it should have captured 69.242.229.136 at the time. I'm set for Using DHCP, as necessary. I did resets to the Airport Express but it continues to capture and send the same 10.0.1.2 IP address. The end result is that I can't access the Internet.
Can you help?

Below is the online manual for the AE. So you have been using the AE to access the Internet for 18 months and then last night .... poof? If so, use the assistant like they say to configure it. You could also change your Airport card configuration to accept DHCP and let the AE give you that address. Your computer has two ways to connect, so you may be mixing up the wired with the wireless. Wired you would get the 69.xxx.xxx.xxx and wireless you would accept the address from the AE ( use DHCP ) on your AirPort card on your MAC.

Time Capsule and Airport Express not working correctly.

Just bought a Time Capsule to replace my router....and now my Airport Express is no longer showing up in Airport Utility.
Also, the speed is awful. I have 25MB coming into the house via ethernet....but a speedtest on my wireless network shows me running at 4.5Mb download speed.
I spent $500 on the Time Capsule. I don't understand it.
Anyone have suggestions?
Tony

I would suggest, reconnecting the Express to the TC again. Use the AirPort Utility to make ALL configuration changes including the network extending settings. Then restart both base stations and check that the settings are still good. Then disconnect the Express and give it a few minutes to initialize. It should connect. If not, then the issue may be either the distance or obstructions (like walls, ceilings, floors, etc.) that is preventing the Express from getting a signal from the TC that is adequate enough to extend.

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests.

AirPort does not have an IP address and cannot connect to the Internet.

Wi Fi problems
I have recently changed from a old netgear router to using a vigor 120 modem with airport extreme
Internet connection is established but my airport express reports "AirPort does not have an IP address and cannot connect to the Internet." although status is ON and the correct wifi address appears.
My iPhone also identifies the correct network but cannot connect
Any suggestions?

I don't have any phones, so not aware of the options, but on a Mac to fix this problem it'd likely be...
Instead of joining it from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed. Before I went through network diagnostics and all of that stuff in system preferences, and then I tried the "Join Other Network" method, and now it works like a dream.
https://discussions.apple.com/message/17028445#17028445
Or...
Go to System Preferences
Click Network
Highlight AirPort and click Configure...
Choose “By default, join: Preferred networks”
Select your access point and Remove your access point with the minus button.
Launch your keychain access in Utilities and delete your access point keychain entry.
Reboot

Airport Express not Appearing in iTunes/Airport Admin Utility

After upgrading to iTunes 7, Airtunes did not work, so I followed the tips on the forum discussions, on MacOSXHints.com (resetting the IPv6 preference) and so on.
However, now iTunes will not recognise the base station at all. I think this is connected to the fact that the base station will also not appear on the Airport Admin Utility list. BUT... I am able to access the Airport Express by entering its IP address and password via the "Other" button. This has allowed me to check the AEx configuration settings, reset the hardware, re-upload the firmware, and even re-configure the AEx from scratch.
I am able to use the Internet through the AEx, and the network appears in my airport menu bar list, so I can select it and other wireless networks in range... It seems that iTunes and Airport Admin Utility just cannot see it. I have tried every combination of 'soft reset', 'hard reset' of the Aex, trashing of various airport admin utility and itunes preferences, and restarting software and the whole computer but this problem still persists.
Any ideas?? iTunes 7 is great, but I want my Airtunes back!!
Thanks in advance - Danny

you may be suffering from wireless interference.
download iStumbler and note the channels other networks in the vicinity are broadcasting on, then change the channel your network is using as far away as possible from those.

Airport express not detected in Utility

I have one Airport Express device only to play music from my pc over my homestereo. Worked fine until now. The amber light is on , reset doesnt help, can not manually configure because my Utility can not detect the airport device, can not update to newer version because my pc doesnt allow internetconnections from within programms ( like it also blocks Hitman Pro) and i can not access firewall settings after i had a nasty virus so i can not set the firewall to allow connection.
I do not think it has anything to do with it but i reset my Linksys Router after i lost my password, internet works fine. I do not use the airport device for internet or printer or anything, just the music. Should i reformat my pc and install everything new and then try to install the airport device again?

The connection between your computer and an AirPort Express device is via the local network created by the router. There is no routerless-free connection, so you need to be sure that the AirPort Express is configured correctly to join the local network.
By temporarily connecting your computer to the AX device by Ethernet cable, you should be able to configure the AX device correctly.

Airport express not working since today's itunes update

Since updating iTunes today, Airport Express not working. More specifically, the Airport software will recognise the device exists, but iTunes cannot connect to it, just getting error message.

Airport Express (not n) with ethernet hub and as wireless base

Will Airport Express do this?
I've got a cable modem. It connects by ethernet to a hub. Airport Express (not n) connects to the hub by ethernet. My laptops (MacBook and HP 69xx WinXP Pro) connect to AX and internet just fine.
In that same hub, I want to connect a D-Link DNS323, which I wish to be made accessible to the wireless network provided by AX. Here's a sort-of diagram:
cable ethernet
modem ---> hub <--- Airport Express <--- laptops, AppleTV, etc. by wireless
^
|
|
D-Link
DNS 323
Can AX (old style, not n version) use its ethernet connector to both communicate with my cable modem and with other wired ethernet devices through my hub?
Thanks for helping. I tried searching for similar posts, but I failed to find an answer.

With only the hub, the NAS, and the express, you can't access both the internet and the NAS wirelessly at the same time. Here's why:
The AirPort Express has only one Ethernet port. That port can either act as a WAN port or a LAN port, but not both at the same time.
You need the Express to be connected to the internet. Unless you have another wireless router (Apple or otherwise), it will have to be connected through its Ethernet port. Therefore, the Ethernet port must act as a WAN port.
The NAS, on the other hand, is part of your network. For it to be connected, the port must act as a LAN port.
This means that the NAS can't be connected to the Express via Ethernet because then the port would need to act both as a LAN port and a WAN port, which it can't do.
This means you'll need an additional wireless router if you want to access both the internet and the NAS at the same time.
If you have another wireless router (it doesn't have to be an AirPort), I can help you configure it to work with your current network so that you can access the NAS.

Airport Express not showing name given

Hello Community,
I have the latest Airport Extreme and Airport Express. I am also using the latest Airport Utility, 6.0.
I am using the Airport Express to extend my network. However, under my Wi-Fi icon (upper right icon), I can not see the name given to my Airport Express. Therefore I can not manually select it. I can see it's name in iTunes, if I want to remotely play music and under "Network>Advanced" I can see it has the "same" name as my Extreme, but with an "AE" after the Extreme's name. Im sure that means Airport Express. Also, of course I can see the AE and the name given to it using Airport Utility.
Question, why is the name given to the Airport Express not showing up under my Wi-Fi ? I could have sworn when I first configured it, it showed up under the Wi-Fi drop down menu under "Other Devices", I believe it read.
I am running Lion, 10.7.3
Any help please ? Thank you in advance !

By the way, I set up the Airport Express wirelessly. Should I have connected it with an Ethernet to my Extreme to set the Express as an Extended network device ? Thanks !

Airport Express not seen in Airport Utility! PleaseHelp!

Airport Express not seen in Airport Utility! PleaseHelp!
Changing Utility version did not help.
I have successfully used my Airport Express 802.11n A1264 (1st gen.) to stream my iTunes music wireless to my living room stereo. Lately my Airport Express looses connection after every restart and does not show in the Airport Utility.
I run 10.6.8 on a Quad core Mac Pro. up to date on al software updates per 10.6.8 I use a 3rd gen. Airport Extreme 802.11n.
W.W.

I actually did this by myself not into the computer but a secondary Ethernet port on myTripple play Fios modem.
The Express showed up right away. I did the reset and set it up in the utilities to join my existing wireless network. I don't remember all steps but at some point it asked me to put in internet info, I did not, and then it asked me if I wanted the amber flashing stoped so I could use it to stream music. I clicked yes and the set-up finished with a green light. After I disconected the Ethernet cable, plugged in the Express in my living room stereo wireless, it has been working normal since. I restarted a few times, green came right back.
James since you had the right idea I gave you the 10 points. Thank you for being helpful.

just did firm ware update on time capsule an now my airport express not connected do to air port utilities doesn't support base station ?

I have been experiencing some networking problems
Welcome to Apple's discussion groups.
I have the latest Time Capsule ("TC"), an old Airport Extreme Base Station ("AEBS") bought in 2007 and 2 Airport Expresses, one bought in 3 months ago ("AE-Alpha") and the other bought back in 2007 ("AE-Beta"). All of them have been updated with the latest firmware.
Based on those dates, the AirPort Extreme is probably flat (as opposed to dome-shaped), making it 802.11n-capable. The Newer AirPort Express is probably an 802.11n-capable model A1264, while the older one is probably a model A1084 or A1088.
I use {the TC's} DHCP function ... to avoid unauthorized use.
This a discussion for another thread, but that's not what DHCP is for.
The wireless setting for it is to participate as WDS Main, but after reading various posts, it seems WDS is a bad idea
With that older AirPort Express you're stuck with WDS unless you decide to replace it with a newer model.
The AEBS is currently setup as being a WDS Relay at the moment
Why a relay? That's only needed if there's another base station "beyond" it that is configured to depend on it.
Since the AEBS is connected to the TC via Ethernet, you should probably configure it as a "roaming network":
http://discussions.apple.com/thread.jspa?threadID=2273124
{The AE-Alpha} connects fine as WDS remote at the moment
I don't have any experience with mixed WDS and non-WDS networks, but since it's 802.11n-capable, you may be able to configure it to "extend" the network of the TC rather than as WDS. Look for a setting on the TC to "Allow this network to be extended".
Physical location:
AEBS in one end, TC and AE-Alpha in the middle while AE-Beta on the other end.
A device such as "AE-Beta" that's supposed to extend a network shouldn't be "at the end" but should be half way between the central base station and the clients that need an extended network.

Airport express not working in Japan "no ip address"

Hi,
We have an Airport Express which we use at home to create a wireless network for our iphones and a laptop. I traveled to Japan 2 years ago and plugged my hotel`s ethernet cable in and it worked fine.
We are in Japan now and, for the first 4 days, in our hotel, after plugging in the e-net cable, we kept getting a message saying we didn`t have a valid IP address. The hotel had wifi available so we didn`t bother pursuing it. Now we are at my wife`s family home and tried again and get the same message.
The set up is Fiber Optic cable going into a modem. One E-net cable coming from modem plugged into the WAN port on the AE. AE to iphone seems fine but get this message:
"Your Airport base station does not have a valid IP address. Make sure your base station is connected to your broadband modem or local network, verify your settings and try again......etc"
I tried the cable we brought from US and the cabvle that was going from the modem to the computer.
I unplugged the modem a couple of times to reset it.
I tried plugging the E-net cable into the LAN port.
Unfortunately it`s hard to experiment because the computer is not a Mac and is all in Japanese. It took forever just to get online to check email and typing is a nightmare with this keyboard. My Brother-in-law is only accessible late at night after a long workday and with a three person communication chain it`s not easy to troubleshoot. And worse of all, every time I unplug the modem or disrupt the connection, my Brother-in-law has to sign back in to get the computer back on line.
Any help would be appreciated.

I created a network like you said
Not quite... "join" a wireless network. Big difference:
Open Airport Utility, select your Express, click Manual Setup, select the AirPort pane, and in "Wireless Mode:" select "Join a wireless network".
Do that.

That's asking too much. Your AirPort can create a new network, extend an existing network (Apple Base Stations only), or join an existing network (any kind).
In your case, the latter choice is the appropriate one.
From the AirPort Express FAQ:
Question: I have a third-party 802.11b/g/n wireless access point. I want to put AirPort Express next to my home theater and stream iTunes to it. Can AirPort Express join the third-party network?
Answer: Yes. AirPort Express can join a third-party network in client mode, or if it is connected via Ethernet to a LAN port on the non-Apple wireless access point.
This KB article describes how it works: AirPort Express: What is client mode

Time Capsule, DHCP not providing correct gateway address

I have gone back and forth between my AP Extreme and Time Capsule and have determined that Time Capsule is not providing the proper gateway address to my wireless clients. Instead of providing the correct gw address it provides the address I assigned the base station. This is contrary to my Airport Extreme which provides the proper gw address to my wireless clients. Sounds like a bug in the DHCP base station software. Any thoughts?

I have a very similar problem. I originally had cable broadband and a Airport Extreme (AE) upgraded to 7.3.1 all worked fine. The AE was being used as a DHCP server to distribute the dynamic IP address provided by the ISP. I then replaced the AE for a Time Capsule (TC) and installed a new 802.11n Airport Express. I upgraded the TC and AExpress to 7.3.1. The TC was setup identically to the now replaced (disconnected and switched off) AE.
Unfortunately the TC failed to work as a DHCP server. It did not recognize the ISP provided dynamic IP address and replaced it with an 'Invalid' IP address which of course meant no internet access. I then replaced the TC with the original AE (identically set up) and all worked fine, including the AExpress.
While I wait for Apple to fix the TC firmware I am running the AE as the DHCP Server and the TC as a wireless bridge to the AExpress. Time Machine is recognizing Time Capsule and backups from two macs are working fine.

Airport Express not visible to Windows XP laptops - works with MacBook Air

Frustration. I've been searching these Discussion boards and none of the proposed solutions seem to work for my problem.
I am trying to set up a brand new Airport Express to stream iTunes wirelessly to my home entertainment system. The majority of my music resides on a Dell laptop running Windows XP Pro(SP3). I have a home WPA2-PSK WiFi network using the modem provided my local internet provider (Qwest). I've been trying to set up the AEX as a client on my existing network. I have turned off my laptop's firewall and virus protection.
I used the Airport Utility to configure the AEX (setting the AEX name to something without spaces, setting a password, choosing join an existing network, selecting the correct network type (WPA/WPA2 Personal), entering my network's password, and enabling AirTunes). This seems to go well. After the restart, the orange light turns to a solid green light, but I get the familiar "Airport Utility was unable to find your Airport wireless device after restarting." I can get the Utility to retrieve the above group of configuration settings by entering the IP address and password via the Configure Other on the File pulldown. Despite the correct settings seemingly being saved to the AEX and the green light, the AEX is not available to my iTunes.
At this point, I'm about 8hrs into this setup process. I have been through all of the recommended permutations of AEX hard reset (paperclip in the AEX reset button while plugging it back in and waiting for the rapidly flashing orange light), laptop reboot, linking my laptop to AEX via ethernet cable for setup, hook AEX to wireless modem via ethernet cable for setup, hook AEX and wireless modem to laptop via ethernet cable for setup, etc. Each time, the AEX settles out to green, but it is not seen by Airport Utility on the Windows XP laptop. I've now tried with a second Dell Windows XP laptop (also shut off the firewall and virus protection) with precisely the same results.
Today I brought home my office MacBook Air. I reset the AEX and re-installed it as a client on my network and it was immediately recognized by the MacBook Air, and went on to stream iTunes wirelessly to my entertainment system (proof of concept). When I switch back to the Windows XP laptops, the AEX still cannot be found by the non-Mac laptops. They can find the AEX temporarily when I enter the IP address to the configure other, but cannot find the AEX after the reboot. The AEX is only available to the XP machines when the AEX is hardwired to either of the laptops via an ethernet cable.
I still just want to be able to stream iTunes wirelessly from my primary Windows XP Dell laptop to my entertainment system. Please help. Thank you.

WPA2-PSK (AES) = Apple WPA2 Personal
WPA-PSK (TKIP) = Apple WPA/WPA2 Personal
See if you can change the setting on your wireless router to read WPA-PSK (TKIP).

Is it normal for airport express not to show up in utility when extending a network?

Hi, with the help of this community, I think I successfully extended my wifi network by using airport expresses, connected to my time capsule, via my houses electrical system (via powerline adaptors), which ultimately connect via an RJ45 cable to the airport express. I tried to do it all with the same netwrok, so I do not need to switch to different networks when I move about the house.
I think it works because my signal strenght is much stronger than before I added the powerline adaptors. So, why am I back here?, two things. First is I want to make sure I did this all correctly, as I am adding a few more of these powerline adapters as they have really changed my wireless experiences.
What should the internet setting be on the time capsule and airport expresses. I have it set the "connection" to off (bridge mode) on the TC and the express units. But the express units blink yellow and says there is a NAT/DHCP error. something about the time capsule rejecting the sharing? so I chnage the TC to share a public address and the express to off (bridge mode), and I think this works.
But when I do this, none of the express units show up in the utility anymore. Should I just take it as a blessing that it seems to be working, and not mess with it?
What should all the setting be? I am sure that I should be able to see all the units in the utility.
Thanks if this makes any sense to you.

But when I do this, none of the express units show up in the utility anymore. Should I just take it as a blessing that it seems to be working, and not mess with it?
Did you power cycle the entire network to get things in proper sequence?
If not, power off everything....all devices....order is not important
Wait a few minutes
Power up the modem first and let it run a moment or two
Power up the Time Capsule the same way
Power up the powerline devices
Power up each Express one at a time
Power up other devices one at at time
What should the internet setting be on the time capsule and airport expresses.
The setting on the Time Capsule will depend on the type of modem that you have connected. It sounds like the "Share a public IP address" would be correct for the Time Capsule. Everything else must be in "Bridge Mode"
Each of the AirPort Express devices must be configured to "Create a wireless network" using the same wireless network name, security setting and password as the Time Capsule network. Set the Channels as "Automatic" and double check as the last configuration step to make sure that they are set for Bridge Mode.
Then restart the entire network as outlined above and you are in business.
The Express devices should definitely show up in AirPort Utility when you have everything set up.
