AirPort Express doesn't connect to router via WLAN anymore

Hello
A few days ago I've bought an *AirPort Express (802.11n)*
When I wanted to test it for the first time, I set it up to *connect to an Existing Wireless Network* and it worked, I could for example stream music from iTunes or print something.
The main reason I bought the APExpress was to extend the range of my wireless signal area, and since my router's got WDS ability I set the *AirPort as a part of the WDS Network* and logically I connected it via Ethernet to the router, and again everything worked.
Now my problem is:
yesterday I wanted to use the APExpress to stream some music to the kitchen,
so I chose the profile in which it was set to connect to an Existing Wireless Network, like I already described above.
But now it doesn't work; the APExpress doesn't connect to the router via WLAN, though there's the green light which's supposed to mean that everything's fine but it doesn't show up in the AirPort Setup Assistant.
As soon as I connect it via Ethernet to router it shows up and you can start streaming music or whatever, but without Ethernet it doesn't connect to the router anymore.
And that's weird, cause for the first time I used the device it worked, but now it doesn't!
Now I would be very thankful if somebody could help me to solve this problem.
Cheers
Yasser

I've tried a bunch of 10.1.10.x's and none of them seem to work. The computer that does work has gotten the IP automatically, though.
I've been doing some reading, and it seems as though OS X self-assigns a 169.254.x.x IP address whenever it tries to get an IP from DHCP and fails. Aside from turning off both the router and the modem for about 15 minutes, is there any other way to make the router give me an IP address? And why does one of the computers work? Do you think that if we tried to renew the DHCP lease on that computer, it wouldn't be able to get one?
I'm not sure what the router is set to give out. How would I check that?

I've just changed my router and whilst my laptops sync ok, my G4 tower which connects via an airport express doesn't connect to the internet. I think it's something to do with the IP or DHCP settings but have had no success, any help much appreciated.

Hi Jake,
Is it connecting to the Router or Modem?
Is the new Router using maybe WPA2 encryption? If so, G4s can only do WPA or less.

Airport Express doesn't connect to internet

Got a Airport Express to replace my old router. When modem is run into old router get internet with no problem. When I plug it into the Airport Express I loss internet but Airport Express gives green light. Go into utility and see internet disconnected but Airport Express is green light. I have reset router and airport express and computer in every possible combination possible.
Any ideas on the problem??

Power off the modem for 30 minutes by pulling the power cord from the back of the modem or from the wall. A longer power down period will not hurt.
If the modem has a battery that is easily accessible, pull the battery as well.
Then reinstall the battery if it was pulled, and start up the modem and let it run for 5 minutes by itself.
Then connect the Ethernet cable from the modem to the WAN "O" port on the AirPort Express and start up the Express to see if the modem will now associate correctly with the device.

Airport Express: can't connect to internet via adsl modem

I have an old Airport Express which has worked fine in the past and a new ADSL internet account which works fine when I connect to it via PPoE Built-in-Ethernet. But despite following all the instructions in the Airport Setup Assistant I can't get Airport to work with the new modem (it works fine for AirTunes though). The thing is I don't really get how it could work with the new modem seeing as the Airport Setup Assistant doesn't ask me at any point what the username or password is for the new account.
I guess I'm missing something obvious here. Does anyone have any ideas what it is?

Thanks again, I tried that but it didn't work either. Going back to basics, it might help if I tried to set out what I'm trying to take in a bit more detail:
1. Having just moved house I have a new ADSL line and modem installed by the phone company and a new ISP that has provided me with a username and a password. Using those I have no trouble getting internet via an ethernet cable connecting my iBook and the Modem.
2. I plug the ethernet cable into my AX and then plug the AX into the wall.
3. Then I follow the AX set up assistant guide for setting up a new base station.
4. I click the box for DSL or Cable Modem. I don't click the box for Router
5. This is the step I'm most unsure about. Because it is the default option I click the box for DSL or Cable modem ... or over Ethernet with an IP address assigned automatically using DHCP." I do not tick "I do not use DHCP". But I don't really know what that means.
6. AX tells me that it is configured as follows: TCP/IP: using DHCP and IP Address: Provided automatically.
7. When I open Safari it tells me that I'm not connected to the internet. Clicking the network diagnistics box gives me green lights for everything up to and including ISP but not for the internet.
Someone here mentioned that I might have to reconfigure my modem as a router. Is there anything to that?
Thanks again for your help.

Airport express doesn't connect to motorola 2210. how to set up?

just get a flashing amber light on AX. when i connect modem directly to via ethernet computer can connect to internet.

I'm familiar with that device. You will need to re-configure the modem to work in "Bridge Mode" or "PPP is on the computer or router".
Right now, it is set for "PPP" is on the modem, correct?
Open the web page for the modem and look for the PPP Location tab on the left.
Then, the AirPort Express must be configured to "Connect Using = PPPoE" and you enter your user name and password into the setup of the AirPort Express.
Power off both the modem and Express. Start the modem first and let it run a moment or two. Then start the Express.

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?

Airport Express doesn't connect to wireless network after firmware update

Hi,
I just updated the firmware on my Airport Express to 6.3 and now it will no longer join the network. I have tried reseting to the factory defaults and Airport Utility accepts all the information and shows the unit with a green dot next too it. However, the unit is still flashing amber and in the final step where the Utility tries to save the configuration the update fails and I get the following error message:
An error occurred while reading the configuration.
Please make sure your AirPort base station is plugged in and in range of your computer or connected via Ethernet and try again. (-6753).
I am using an old style AirPort Extreme as a base station.
Can anyone help?

Wow, really no suggestions yet? This is a first for me, on the Apple Discussion boards!
Can anyone help?

Airport express doesn't connect to internet at work

I'm currently connected to my home network using my Airport Express card. However, I can't connect at work. Here is a screenshot of my System Prefs>Network>TCP/IP page:
-One iMac at work previously has connected wirelessly, and stopped connecting once it restarted and tried to reconnect to the network again.
-Another iMac still does connect to the network. While trying to figure out what the difference was, I realized that it has a Router Number:
Is there any other difference that could make this happen? How do I fix it? Thanks for all your help.

Airport express doesn't connect to fritzbox 3370

Hi,
Two days ago I installed a fritzbox 3370, which works as modem and router. Cause my room is on the 2nd floor and the fritzbox is located in the basement, I had an ethernet cable plugged in my airport express and created my own wifi network. This worked fine until we got the fritzbox.
I can't configure it the way that the airport will connect to the internet. I switche dhcp off at the airport and it is running in bridge mode.
Can you help me?

Airport Express doesn't connect to HughesNet

I have purchased an Apple Airport Express, and when I plug it into the Hughesnet Modem, the indicator light = amber blinking. I have successfully connected to other routers (Linksys). Any Ideas?

If you can connect to your AirPort Express with AirPort Utility, it should show you why the Express unit is unhappy.

Airport express doesn't connect to pc only

Hi, I have had 2 Airport Express' in the last couple of weeks. The first worked perfectly with all of my devices but a relative took it as I was just setting it up for him. I decided to perchase one for myself after getting amazing speeds on my Win7PC and across the 2 iPads and 3 iPhones we have around the house. The problem is that this new Airport works terrifically with my apple devices but now it does not connect to my PC, or if it does, I get 0.5mbps for less than a minute before it disconnects. I have tried resetting the airport and reinstalling my wifi card drivers to no avail! A fix would be greatly appriciated,
Thanks
Josh

The wireless voodoo gremlins at work.. !!
Two identical setups give completely opposite results.. makes wireless such fun.
Do a factory reset of the Express.
Setup wireless with a short name.. no spaces and pure alphanumeric.
See if that is enough..
No go.. set the wireless channels.. test 1, 6, 11 on 2.4ghz and say 40 and >150 on 5ghz. the exact channels is not important for 5ghz.. they are important on 2.4ghz as they are the only channels that do not overlap.

Airport Express not working with wireless router

I just bought Airport Express to play music on my stereo. My PC running XP is connected to my wireless router (TeleWell TW-EA510v3) with ethernet cable and airport express wirelessly. Problem is that Airport Utility (and iTunes) can't find AE if it's not connected to router with ethernet cable.
I can connect to AE from Aiport Utility by "configure other" option so it's connected to my wireless network correctly.
Is this kind of set up even possible (pc wired to router and AE wireless)? I have tried tried WEP, WPA/WPA2 and no encryption on my wireless network and AE connects ok every time but Airport Utility still can't find it. I even tried to make a WDS network but AE was not compatible with my router. Now I can't come up with anything else to try.
Is there anything else to do? Should I buy WLAN adabter to my PC and would AE work then?
Why can't Apple make Airport Utility to recognise AE with given IP like with "configure other" option? Should not be too hard to program?!

Follow the isntruction lisetd below...they work.
Actually, the ae is a slick device, once you get it to work.
Make sure that one (or both) checkboxes in Airport Utility > Airport Express tab
(middle of page) are not checked...if one or both are checked, they limit (hide) wireless connectivity options (e.g., WEP-64) to choose from.
P.S. You must have patience: it may take a couple of minutes to establish the connection and turn the led to solid green. So, give it a chance.
===============================================================================
OMG!!! You are da man!!!
I have this streaming perfectly now!! Here is what I did for others to see and use (it does work perfectly)
Step 1) Clear/Reset the Airport Express
Step 2) Connect the Airport Express directly to the Router/Modem via Ethernet to set up Wireless
Step 3) Do it via the Manual Set-up Effort Listed Below following:
AirPort > Base Station
o Base Station Name: <rename or leave default>
o Base Station Password: <enter desired password>
o Verify Password: <re-enter desired password>
o Remember this password in my keychain: (optional)
o Set time automatically: (unchecked)
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing Linksys wireless network>
o Wireless Security: <select the encryption type of the existing wireless network> I have 64bit WEP
(Same as 40bit on the drop down menu)
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)
Once it congratulates you, unplug the ethernet cable
Verify in Aitport Utility that it still recognizes (if not, repeat the above). Note this may take a few minutes, so be patient.
Now place the airport express with your stereo (or whatever) and again be patient as it tries to find the network
(mine took 4 minutes) then it turns green and you are off listening to music on your stereo downstairs in another room.
Frustrating when it does not work at first, but keep trying and it will work!!
Thanks everyone for your help!!

AirPort Express won't connect to existing wireless network

I just purchased the current gen AirPort Express and it won't connect to my existing wireless network. My current wireless network is on a D-Link DIR-827 and it operates on both the 2.4 and 5.0 GHz bands. My current gen Apple TV is connected to the D-Link wirelessly and it works fine. Basically all I want to do is have a pair of speakers attached to the AIrPort Express and stream music to it via AirPlay from all my devices. When I use the AirPort Utility, I keep getting the error that 'it's setup to join an existing wireless network but it can't find it.' The light flashes amber and I can't connect to it. Right now I've setup a new wireless network for my AirPort Express but ideally I would like to have it join my existing network so all my devices can stream to it without having to connect to it seperately.
Thanks,
Ata

Hi Ata,
...Right now I've setup a new wireless network for my AirPort Express but ideally I would like to have it join my existing network
If you already configured your AirPort to create a separate wireless network, it would be best to reconfigure it to "join" your existing network by starting over with a "hard reset": Press and hold the reset button and keep it depressed, continuously, about five to ten seconds, long enough for it to flash amber. Then, it will glow amber steadily for about a minute while it starts up, then it will flash amber slowly indicating it needs to be configured.
It will then appear in your Mac's Wi-Fi menu like this:
Select it. AirPort Utility will load and walk you through its configuration.
Be sure to select the option to "join" your existing network, and not create a new one. In that configuration, it will serve as a device for music streaming only, and cannot serve a wireless access point. For that, your router would need to be a genuine Apple AirPort Base Station.

WRT160NL and AirPort Express 802.11n Connection

I have a Linksys WRT160NL that is currently connected to 2 Apple AirPort Express 802.11n via WiFi.
The connections are Cable Model via ethernet to WRT160NL
WRT160NL ethernet to PCs running XP and Vista
WRT160NL WiFi to laptops at 802.11g
WRT160NL ethernet to DirecTV HD Box
WRT160NL WiFi to Airport Express to ethernet connection of DirecTV HD Boxes (2 connections) (802.11g)
This current setup works. The hard wired components work as expected and the wifi to the AirPort Expresses work as well. The only issue I have is that the AirPort Expresses are only connecting to the the WRT160NL via WiFi at 802.11g speeds. I want to be able to conenct the AirPort Expresses at 802.11n speeds as I am having some streamin issues for High Def video. I verfied in the DHCP Client Table of the router that the AirPort Exresses are connected via "Wireless-G" to the routers. The AirPort Expresses are running the lastest firmware from Apple and I am running Firmware Version: 1.00.01 B17 on the router.
Any help/ideas on how I can connect the Apple Airport Express to the WRT160NL at 802.11n speeds? Are these 2 devices just not compatible with each other?

Thanks for the reply Scrooge. I have verified that the Apple Airport Express is 802.11n complaint:
http://store.apple.com/us/product/MB321LL/A/AirPort-Express-AirTunes?fnode=MTY1NDA0Mg&mco=MTA4NTc4MTE
I have also checked to make sure tha the router is set to Mixed mode:
Mode:     Mixed
Network Name (SSID):     xxxxxxxxx
Channel Width:    Standard - 20MHz Channel
Wide Channel:    N/A
Standard Channel:    2
Security:    WPA2 Personal
SSID Broadcast:    Enabled
The airport expresses are still connected at 802.11g according to the DHCP Client Table from the router. Is there any way to force the Airport Expresses to connect at 802.11n?
TIA

Use Airport Express Brick N to extend network via ethernet

I have the old brick-style Airport Express N model, which I'm currently using to extend the newer Airport Express hockey puck. The hockey puck is setup to with DHCP and creating the network. The brick is in setup to extend the network using DHCP and in Bridge Mode. When I plugin the Ethernet cable from the Ethernet port of the hockey puck to the brick, I lose all internet connectivity. I seem to recall reading some documentation that said the brick would support ethernet rather than just over-the-air. Thanks for your help!

My question is: can I connect the two via ethernet cable to the extending is happening over the air? I'm not sure the brick is capable of this?
It is possible to "extend" in two different ways:
1) Extend using a wireless connection between the AirPorts. Apple calls this "extend using wireless" during the setup. When you extend this way, about half of the potential speed on the network is lost.
2) Extend using a wired Ethernet connection between the AirPorts. Apple calls this "extend using Ethernet" during the setup. When you extend this way, full bandwidth on the network is maintained since there is no signal loss in a wire.
If you want to "extend using Ethernet", the 2nd Gen AirPort Express must be the "main" router, so you will need to reconfigure it for that purpose. The 1st Gen will also need to be reset back to default settings and reconfigured as well.
Once the 2nd Gen Express is working correctly as the main router, connect an Ethernet cable from the LAN <--> port on the 2nd Gen Express to the Ethernet port on the 1st Gen Express and use AirPort Utility for the setup.
