802.11n Airport Express won't connect to Internet

Hi,
I have recently purchased a new 802.11n Airport Express which works fine with the Airport Utility, but will not connect to the internet through the Ethernet.
It is plugged directly from the cable model into the 802.11n via Ethernet.
I know that it is not the modem/internet service provider because when I pop my old 802.11b/g (model A1084) everything works fine, and I connect no problem.
The settings appear the same, but with the old model I get internet, with the 802.11n I get the flashing amber light. If I set it up manually, and input the same IP, Subnet Mask, and Router number that is working for the 802.11b/g model, I get the solid green light, but no internet.
Originally, I assumed I'd just picked up a lemon, so I exchanged it and I am getting the exact same results so I must be doing something wrong.
Any ideas?
I wanted to extend my network, but use the 802.11n as the internet input so I could take advantage of the faster speeds.

Welcome to the discussions!
You mentioned that you had a cable modem. Although the ISP will claim otherwise, in many cases it will take 20-30 minutes for a modem to completely reset. The reset is needed whenever you change the device that is directly connected to the modem.
Power down the modem and pull the battery if it has one. Power down the rest of the system as well.
Power up the modem first and let it run for 5-10 minutes, then the Express for a few minutes, then your computers.
Once you get things going, we can look into the next puzzle of extending the network. Please post back when you have the "green" light and internet.

Airport Express won't connect to internet...all is green

My Airport express won't connect to established Network in my office. I am connecting to a 10/100 base T in the building (as the modem, I assume) and want to broadcast the network for wifi. Express sets up ok, but than cannot find the internet....any suggestions? The port is live as I can directly connect it to my Mac Book and find the internet without issues.

It is possible to have a green light on the Express if some network errors are overlooked, so it may be necessary to reset the Express back to factory default settings and start over again.
Keep in mind that some networks will not allow a router to be added to the network, so a computer might work, but a router may not.
What model number of AirPort Express do you have?
What operating system are you using on the MacBook?
Do yo know if the Express has been configured to operate in Bridge Mode?

Airport Express won't connect to internet

I configured the AX from factory settings about 3 times. I tried configuring with "using DHCP." I've tried to manually enter the IP address info to both the AX admin utility and through my macbook preferences. I've followed all the trouble shooting tips. I've restarted everything I can restart. I've even changed ethernet cables.
Ultimately, my mac says I'm connected to the internet on AX (network prefs> TCP/IP) but the AX blinks amber and the cable modem is all green lights, but won't register as "online"
Why can't I connect to the internet? How do I fix that problem?

Ok, let's double-check your AX's settings...
AirPort Express Base Station Setup (AX) w/High-Speed Cable Modem
Modem/Router Power ReCycling (optional)
- Power-off the Cable modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the Cable modem; Wait at least 30 minutes.
- Power-on the AX; Wait at least 5 minutes.
- Power-on the computer(s)
Perform a "hard" reset of the AX (optional)
- (ref: http://docs.info.apple.com/article.html?artnum=108044)
Setup the AX
With the network components powered down, set up the AX, using the AirPort Admin Utility, either connect to the AX's wireless network or connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, try these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- AirPort Network Name: <whatever you wish or use the default>
- Create a closed network (unchecked)
- Wireless Security: Not enabled
- Channel: Automatic
- Mode: 802.11b/g Compatible
Internet tab
- Connect Using: Ethernet
- Configure: Using DHCP
- WAN Ethernet Port: Automatic
Network tab
- Distribute IP addresses (checked)
- Share a single IP address (using DHCP & NAT) (enabled)

Airport Express won't connect to internet via WAN ethernet

I have new model Airport Express (AE)
I am attempting to use the AE as a wifi router in my office. I'm sure the office has some sort of secure internet, although when I hardwire my computer to the internet via ethernet my computer connects immediately to internet with no passwords or logins necessary.
I have set up my AE to create a new wireless network. It is ready to go, but it does not recognize that it is connected to internet. Ethernet cord is plugged into WAN input, and other end is plugged into wall for office supplied internet.
AE will not recognize that it is connected to internet.
I assume this is due to something with the office supplied internet being secured or "special." Is there a work around here, or suggested next steps?
Thanks.

If you get all three together, "Ethernet unplugged" would pretty much explain the other two errors. Troubleshoot that first.
Is the same ethernet cable you are using with the AE the same one that worked with your computer? Is it oriented in the same direction (same end to the wall) as when it was used with the computer? Your office might use a non-standard cabling system or be taking some other measures to deter the use of foreign equipment.
Have you asked your office's technical support folks for any special instructions?

Replacement airport express won't connect to internet

Why can't I get my replacement airport express to connect to the internet

Wonder if you can direct me to any past or present solutions. I have the new Airport Extreme tower. Actually I'm trying number 2 thinking the problem was number 1. Apparently not. I've done multiple factory resets. Even waited couple hours to try reinstall because my provider said there is a Mac or max filter and wait. Anyhow once I'm able to get the AE online(green) not internet connection. I brought my Airport express in and hooked it up and in blink of an eye it's online with internet. Even phone companys stock modem connects. Interesting that the A express summary lists the DNS addresses and domain. Took this information and tried putting it in when retried the AE. No luck. The First AE worked for over week. Phone tech checked switch at office and did line ping.
My DSL provider uses DCHP.Sorry I forgot the name of the box outside at my phone line where DSL connects. Inside I make connection phone jack and ethernet cable.
As I said I've done every form of power down reset. Any suggestion be appreciated. Next stop be Apple.

Can I Use 802.11n Base Station and 802.11n AirPort Express in an 802.11 ac Time Capsule Main Base Station WDS Network?

I havea "wirelessly challenged" 2-story home and need to extend the range. Currently I have an 802.11n Main Base Station with an 802.11n Airport Express Remote. It's not getting the job done (upstairs connection is weak).
I am considering getting an 802.11ac Airport Time Capsule to help, even though I currently only have devices with 802.11n wireless connectivity (future-proof a little).
I an planning on setting up a Wireless Distribution System (WDS) Network:
1.) Setting up the Time Capsule as the Main Base Station connected to a Cable modem
2.) Reconfiguring and Setting up the current AirPort Extreme 802.11n as a Relay Base Station
3.) Reconfiguring and Setting up the current AirPort Express 802.11n as a Remote Station
I cannot "hard wire" one Base Statio to the other.
Will this work?

Will this work?
Unfortunately, no. WDS is a older, very inefficient way to extend the wireless network signal.
As such, newer operating systems like Lion, Mountain Lion and Mavericks do not even offer settings for this older WDS type of network.
In addition, the new Time Capsule has no capabilities to use WDS settings at all, even if you used a Mac with another operating system to try to set things up.
Even if it were possible to set up a WDS network, the speed on the network would be incredibly slow. As you know, WDS only operates at "g" wireless speed levels. Each "relay" or "remote" that you add to the network each cuts that bandwidth or speed in half.
With a WDS "main", "relay" and "remote", the network would be operating at about 14 Mbps......a tiny fraction of what the devices would be capable of providing normally.

trying to extend my wireles network using a 802.11n airport extreme and pluging in a 802.11n airport express
Can you clarify what you mean by "plugging in"? Are you saying that you are pluggin in an Ethernet cable to the AirPort Express from the AirPort Extreme?
Or, does "plugging in" mean wireless?

I have recently changed my bt home hub and now my airport express won't connect to it? Any suggestions?

I have recently changed my bt home hub and now my airport express won't connect to it? Any suggestions?

Anytime you change out a modem or modem router like the HomeHub, the AirPort Express needs to be reset back to factory default settings and then set up again.
The reason for this is that the Express is retaining some or all of the settings to connect to your "old" modem or hub, so it will not work correctly with a new device unless you start over again from factory default settings on the Express.
Power up the Express for a few minutes
Hold in the reset button on the side of the Exprsss for 8-10 seconds, then release and allow a full minute for the Express to restart to a slow, blinking amber light
Now, set up the Express again, like you did originally with the "old" modem or hub that you had previously.

Can i transmit music from iphone to airport express without being connected to internet?

can i transmit music from iphone to airport express without being connected to internet? just from phone to express via local network or whatever it's called.

Do you mean Lan cable? Can this be done wirelessly from itunes to airport express without the internet connections? I can't connect to an airport express that's not connected to the internet.

Airport Express won't connect to Extreme by ethernet

Hi,
Here is my setup:
a) Airport Extreme (802.11n 2nd gen) connected by ethernet to cable modem
b) Airport Express #1 setup to wirelessly extend network
This has worked fine for quite some time.
Now, what I tried to is add a 2nd Airport Express via ethernet, so
the new setup is:
1) cable modem via ethernet to Airport Extreme
2) ethernet connection from Airport Extreme to D-Link 8 port gigabit switch
3) ethernet from switch to several devices (Tivo, GoogleTV,etc) and also to an in-wall ethernet connection to another part of my house
4) ethernet from that in-wall ethernet to another D-Link switch
5) ethernet from that other switch to printer (currently works fine) and to Airport Express #2
6) Airport Express #1 still connected wirelessly
Problem: Airport Express #2 will not connect. Won't show up in Airport Utility. Nothing.
I have tried several factory resets.
After many tries, I finally tried connecting it wirelessly. This worked, and I was able to see AEX#2 in the Airport Utility. But, when I then tried to connect it by ethernet, it shut down my entire network. I can not anywhere find step by step instructions on how to connect the AEX by ethernet to the Extreme.
I have reviewed http://support.apple.com/kb/HT4145 but find no help there.
Looking forward to some great help.

If I switch Express#2 (the one I would lilke to connect by ethernet) to "create" a network, with the same SSID and PW, then I can only see Express#2 in the utility and the Extreme and Express#1 dissappear.
As soon as you set the Express #2 to "Create a wireless network, the setting for Connection Sharing will change from Bridge Mode to Share a public IP address. That is likely what is throwing you off.
Setup Express #2 to "Create a wireless network" using the same wireless network name, same wireless security and same password.
The next...and last....and critical....step before you click Update must be to change the setting for Connection Sharing from Share a public IP address to Off (Bridge Mode).
Now click Update and wait for a green light on Express #2.
Then, you have to power cycle the entire network.
Power off everything in any order you want.
Wait a minute
Start the modem first and let it run a minute
Start the AirPort Extreme next the same way
Then the switch, etc.
You get the idea....keep starting devices one at a time until the entire network is back up.
Now all the AirPorts will be on the same subnet and visible in AirPort Utility.

Airport Extreme (802.11n) & Airport Express (802.11g) single net by wire?

I just bought an Extreme-n to replace my ailing wifi router and wanted to use it with my existing Express-g to make a single wifi network so that I can have my 802.11n devices connect to the Extreme-n and the 802.11b/g devices connect to the Express-g using a shared wifi network. The tricky part is that I want the Express-g to be connected to the Extreme-n via Ethernet, not by relay, to get the best performance. This doesn't seem to be a standard configuration with WDS as it expects the Express-g to be a relay over-the-air, not by Ethernet. Is this possible, or do I have to set up separate wifi networks to do this? For either option, do I need to set up both the Express-g and the Extreme-n to be DHCP servers, or can I just rely on the Extreme-n to serve to both wifi networks?

In Apple's documentation and in threads in this discussion area you will find references to "dual band" networks. That is what you want to set up.
Each base station will create a separate wireless network.
The AirPort Express (AX) will connect via Ethernet to one of the LAN ports on the AirPort Extreme base station (AEBS).
The AX will be configured to create a wireless network and to act as a bridge (not sharing a single IP address).
All clients of the AX and AEBS will get IP addresses from the AEBS.

Airport Express won't connect

I have a G4 quicksilver tower and a G4 ibook. I recently bought an Airport Express to use for wireless internet and printing. I have a cable modem and am setting up the AEX on the tower.
When I set it up as connect using Ethernet, configure using DHCP, all I get is the flashing amber light. Changing the security didn't help with that either.
When I change the it to conect using PPP over Ethernet, I get a green light, but it can't find a PPPoE. Is the account name/service name something that I need to get from my ISP? (They said to use the DHCP)
Is there another setting that can be changed? I'm not real tech-savvy, but it's been two weeks and this is driving me nuts!
Thanks for any help/advice

Amy I'm had a similar problem while connecting my AX to my G4 to use with my windows laptop. (Still not getting internet but I do have a green light! lol)
Mine was blinking amber because I had to tell AX it was ok to NOT have a security setup.
Go to Finder->Applications->Utilities->Airport Utility. When the dialog box opens you'll see the AX on the left. DOUBLE click it and another dialog box opens. In the summary tab you'll see a list down the left side. Hover over and click "security" you should be able to "allow" the set up without security. That worked for me. Of course you can always enable WEP or WPA and that should remedy it as well.
Good luck...

Upgrading to a 802.11n Airport Express Card in my Macbook Pro

I found this question on the forums answered over 4 years ago and thought to ask it to get a more current response given that both hardware and sellers have changed significantly in the time passed.
I've also found it difficult to replace the wireless card in my Macbook Pro. I was able to track down the current part number in my device as being 661-3890; but I figure it may be better just to upgrade to an 802.11n compatible card. I've found a few listings on ebay but they are not straight forward. I want to make sure that anything I might buy is at least compatible with my computer.
A creditable site, OWC, has a part number 661-5048 they sell that is compatible but is on the upper end of the price spectrum. I have the A1150 Macbook Pro (1,1) which I believe is also referred to as the late 2006/early 2007 model. In my research I was able to deduce that some people have had success replacing their cards with the Atheros AR5BXB6 card although there appears to be some debate regarding the different Manufacture Part numbers (482261-001 and 482261-002). There are a few of these listed on auctions (used and new) but the range in price is $100.
I'm new to the Mac screen and would appreciate any help in the right direction as I have yet to find an authority that confidently and clearly states what cards are compatible with my box. Thanks!

I changed cable providers and now my Airport Express won't connect to the Internet. How do I fix this?

I changed to Time Warner cable. Upon doing so, my Airport Express lost its connection to the Internet. When I run the Airport Utility, I am stuck at the first step, which says the AE doesn't have any DNS server addresses. What are they and how do I find out what they should be? And if I supply them, will that fix the problem?

Have you performed a Factory Default Reset on the AirPort Express?
If not, the Express is still remembering the settings that you programmed into it when you configured it to work with your old modem.
The Express is "looking" for your old modem, but it does not "see" 'it because it is no longer there...so it can't connect to the Internet.
If you have not already tried the Factory Default Reset and you need more info about this, post back for more details.

AirPort Extreme (802.11n), AirPort Express, and Client Limit Q

I'm very interested in the new AirPort Extreme (APE) due to the ability to access a hard drive from it for network sharing. I think that is awesome. But I have a few questions.
I am currently running 2 AirPort Express (APX) base stations for my network and am getting great signal strength throughout the house. No real complaints there.
One has the modem plugged into in the basement, and the other is set up as WDS. Unfortunately, I am quickly approaching the 10 client connection limit for the APX, so I was looking for a way to expand it.
If I get an APE and use the APX base stations as WDS access points, will I still be limited to only 10 clients attached at a time? And, since I assume the computer attaches itself to whichever of the three AP base stations has the strongest signal, will I alway be able to access the hard drive attached to the APE if I do that? I understand I won't get the 802.11n speeds (fine, I don't care) , but I would love to keep the APX base stations in my network for stereos and signal boosting.
Thanks for your help.

Is there a way to use the APX without losing bandwidth?
Configure it to operate as a wireless client. See KB 302153, AirPort Express: How to join an existing wireless network in client mode.
Maybe a way to use it as an extension other than WDS mode?
No
And why does it cut the bandwidth in half?
802.11b/g is not duplex so data can only be transmitted one direction at a time since the same channel (and radio) is used to transmit/receive.
If traffic is flowing from deviceB to deviceA, that traffic will interrupt the flow of data in the other direction and get part of the full bandwidth.
Each WDS link cuts the effective bandwidth in half because the traffic has to be retransmitted again. Let's assume that deviceA and deviceB are connected via WDS. Let's say that deviceA is connected to the internet and clientC is wirelessly connect to deviceB. Let's say that clientC is sending a 54 Mb file to the internet.
- 1 second to send 54 Mb file from clientC to deviceB
- 1 second to send 54 Mb file from deviceB to deviceA
So looking at the bandwidth between clientC and the internet, we see that the transfer rate is:
(54 Mb)/(2 seconds) = 27 Mbps
The effect of WDS becomes even more troublesome when you realize that while the data is being transferred between clientC and deviceB, deviceA has to shut off its radio so that it doesn't cause interference with the transfer. This means that other clients of deviceA are waiting. So WDS has large implications for big networks.
