Macbook no longer detects Airport Express Network

I've been using my macbook to connect to my Airport express base station for my home wireless daily for like a year now. Today however, my macbook refuses to connect to the network. After a few scans it detects the network, then when I try to connect it brings up the "this network requires a WEP password" which I put in, and then the connection times out on every attempt.
I tried using the Airport Utility which fails to even detect the base station.
Yes I've restarted my MB, yes I've restarted the express/modem. Thing is, I'm connected to the same network right now on my iPhone which doesn't seem to have any problem.

Update: my macbook can connect to the wireless network at my university, but still not the airport express network.

HELP ibook g3 OSX 10.2.8 no longer detects airport express wireless network

my ibook G3 OSX 10.2.8, airport admin utility software 3.1.1 no longer can detect the airport express wireless network (powerbook G4, OSX 10.4.11, airport admin utility 4.2; airport express, WEP protected, to DSL modem). i just installed an ipod driver update on the ibook, and wireless networking went down on restart. any help greatly appreciated!

you name it : com.apple.airport.adminutility.plist
delete it and do as advised.
This isn't harmful, because it is only a preference list, so it will be created brandnew as soon as you re-setup the Airport stuff.
Mac OS X ( especially Jaguar ) has a tendency to corrupt some plists out of the blue, it is more or less harmless and can be fixed with recreating them plus permissions-repair.
Hint : repair permissions more than one time, it ALWAYS finds something to fix in Jaguar.
You cannot destroy something with these actions, because it is Unix maintance so usual routines.
A tool like cocktail or Onyx ( google them, onyx is freeware ) can help you run such ( and more ) routines on a scheduled base.
Always remember that OS X is no longer "the Mac OS", it is Unix with a nice Desktop, the critical things run hidden in the background, so it has to be treated like any Unix/Linux sort of OS, even if from the outside everything looks nice and kosher..

MacBook can't detect AirPort Express

I have a MacBook 2.4 Ghz which is about 6 months old. I have a Netgear Super G wireless Modem router which I have been experiencing some problems with (does not always connect to MacBook or my older PC). So I bought an Airport Express which I have plugged into an older, more reliable Netgear wired modem router. I want to use the AirPort Express as a wireless transmitter for the wired router. However no matter how I seem to set it up, my mac can't connect to the AirPort Express and the light on it blinks Orange. I know that the router is Ok because I have plugged it straight into my Mac and it works fine.
I tried to do the same with my Wireless Modem/Router and the Airport Express light turned green and it appeared in the airport utility application. However when I turned the wireless transmitter on the router off I was unable to connect to the AirPort Express again.
I have tried to set it up in several different ways (as a bridge or as a new network etc...) and soft/hard/factory resets but nothing seems to work. So I took the AirPort Express back to the shop and exchanged it as faulty only to find that the replacement is exactly the same.
Am I missing something here? Should the AirPort Express connect to the Mac straight out of the box without connection to the internet? Or does it need an internet connection before it is visible in the AirPort Utility? Can it act as a wireless transmitter when connected to a wired modem router by ethernet? If so, how do I set that up?

I want to use the AirPort Express as a wireless transmitter for the wired router.
Mine is set up that way and works fine.
Should the AirPort Express connect to the Mac straight out of the box
Not for what you want to do....
1.) Plug the Express into a wall socket and connect an Ethernet cable from your MacBook to the Express.
2.) Open System Preferences -> Network and set a Ethernet Only connection (turn off all connections except Ethernet.
3.) At this point the Express will show up in the Airport Utility. (If it does not show up, use the reset button to return to factory defaults)
4.) Open Airport -> Wireless and set up a simple (Open, no security) wifi network.
5.) Apply and restart the Express
6.) Open Internet and set up DHCP addressing for the Express.
7.) Apply and restart the Express.
8.) On the same page - at the bottom - set the Connection Sharing to OFF (Bridge Mode).
9.) Apply and restart the Express.
10.) Unplug the Express from the wall, and turn off the wired router. Move the Ethernet cable from the MacBook to the wired router. Restart the router and then restart the Express.
11.) WAIT - go have a cup of coffee. Sometimes my Express takes two or three minutes to obtain an IP address and go from orange to green.
12.) Open the Macbook, go to System Preference -> Network. Create and Airport Only location (turn off Ethernet, Bluetooth, etc - all other connections)
13.) Connect to the wifi network created by the Express. Again, wait. The Macbook has to first connect to the Express and then the wired router has to recognize the request for an IP address and assign one. (Second cup of coffee maybe.)
14.) At this point, you can open Airport Utility and change the wifi network to a secure hidden network or any wireless configuration that you prefer.
PS Took me a long time and many attempts to figure this all out but my complex little home LAN works just fine now.

How do I share a 3G USB modem connected to my Macbook Pro with my Airport Express?

Hi. I have a 3g USB modem connected to my macbook pro, and I want to try share the signal with my Airport Express (latest model).
Now before everybody screams that it can't be done, I was searching the forums and found a discussion in which someone describes how to do it from 2008, unfortunately it is archived and I couldn't ask the author directly, and the description doesn't go into much detail.
In the thread, the author describes turning internet sharing on to share the USB modem, creating a network on the macbook, then renaming the Airport Express network name the same as the macbook, and setting the AX to Join a Network.
Problem being there is no description of whether the macbook connected to the AX via ethernet or wifi, what settings were changed on the AX eg bridge mode.
Is this possible in theory, and has anybody had any success sharing a 3g USB modem via a macbook pro to an AX? I know there are other options like getting 3g ethernet modems, unfortunately not an option in this case - new house, waiting for DSL to be installed, 2-3 month wait.
Thanks

Well, you cannot use the 3G USB modem plugged directly into the Express. However, you can configure your MacBook Pro to do 'Internet sharing' (SysPrefs>Sharing) over the Ethernet port, and then connect your Express into the Ethernet port. Alternatively, you could always get your MacBook to 'create a wireless network'.

You could always look for open WiFi networks to *cough*borrow*cough* .

Airport Express network suddenly no longer visible - but only for one Mac..

What the..?
My 20" iMac Core Duo can no longer see my Airport Express network. It happened yesterday after restarting the AE a few times.. (I do this and also restart the modem from time to time if the net connection stalls - or I want to boot of my housemate's PC from the network cause she's hogging bandwidth)..
Anyway.. The first restart caused it to not re-appear on the list of available networks, so I restarted again.. then it was fine - it came back. All good.
I reset it again this morning because the net connection was not meeting my expectation and now the iMac no longer sees the AE network.
I can connect to other Wi-Fi networks around me (there is a neighbour with no WEP) but cant see hide nor hair of my own network.
The puzzling thing is that my girlfriend's Mac Book, my other iBook G3 and my housemate's PC can all see it and use the network fine - as normal..
So what has happenned? And what do I need to do?
Between you and me ..This intel iMac has been a bit tempramental ever since I got it.. weird things like this happen to it from time to time.. never one thing that you can point at and say AHA! Faulty [something] but just weird stuff like this... Hmmmm..
Some help would be much appreciated.. Thanks!

Well, from reading some other posts, and trying my own experimenting, I have gotten it to work.
Deleting the keychain did nothing, manually connecting to the network by typing the name in etc.. nothing.
What DID work was using my G3 iBook (which could see the network) to use the Airport Administrator to change the channel from Automatic to manual - in this case channel 7 (a completely arbitrary choice).
The thing I cannot work out is why it had this issue in the first place. It worked fine for months then one day decided that it apparently didn't like automatic channel selection.
The problem is solved but the cause is still a mystery.
Hopefully though, this might help others with the same problem.

Airport Extreme Killed My Airport Express Network!!!

I have been an apple user since 1992 - NEVER HAVE I FELT SO FRUSTRATED!!!! Sorry to shout, but this is as bad as it gets - my kids are screaming at me and my wife laughing!! I have had a reasonably good Airport Express network running in my house with an Express as the primary and internet connected to it by the ethernet port. I worked fine for my Intel iMac and my daughters Intel MacBook, but my son had problems in his room. We then got an xbox 360 and wanted to connect that so I upgraded to an Airport Extreme - Disaster!. Firstly the net went intermittant! Then I rebuilt from scratch restting all devices to factory defaults; worse and worse, the network kept failing to find various base stations. Finally I cut the Extreme out of the loop and tried to rebuild the original network; now Airport utility won't see any base station after I configue it!! Please help if you can!!!

If nothing works, try a factory reset: disconnect the Extreme from power, press the reset button, plug in power while still pressing the reset button, release reset button after 5 seconds or so.
This method usually helps me with problems with my Airport Extreme and Express (this happens seldom by the way). The only disadvantage is that you have to set it up again completely.

IMac suddenly can't detect airport express; all other devices can -help!

Literally overnight and with no changes in settings, etc. my iMac (running the latest version of Tiger) will not detect airport express. My laptop still detects it and connects just fine; my iphone connects via wifi, etc. It's just the iMac that isn't working.
Upon starting up my iMac this morning, I was prompted to "update airport firmware" which I did. Ever since then I can't get the computer to recognize airport.
I've worked on it for 2 hours disconnecting and resetting the modem; checking and unchecking boxes in the network settings, trying to renew the dhcp lease, etc. When I scan for wireless devices, the iMac does not detect one. If it does detect it, I get an "there was an error connecting" message.
So frustrating, especially since I have used this in the same way for over two years and have had NO problems until this morning.
The airport express has a solid green light. Any help is much appreciated!! Thank you.

Hi guys, its me again....
Dunno if is the same problem, but i dont think the problem is the airport, all of you (as i did too) tried making new users, deleting preferences, etc etc...
I tried resetting the airport, and is the same, is something in the computer that trigger the issue after the firmware in the airport, dunno how, but as far i saw, its the problem...
At least for me, after lost the connection, my airport on-off button stop working, if i turn off the airport in the upper menu or in the network preference panel, go off of course, but if i try to turn it on again, desnt work anymore, the button works of course, but never change to ON state...
that button issue isnt a hardware airport issue, is a OS issue...
:S
P.D.: i've trying to replicate some situations on the computer, programs, task etc, bcuz' by some reason there's something that trigger the desconnection... by example, right now i've more than 4 o 5 hours without the problem yet.... but.... i've using none or unusual programs to make the regular tasks...
And last night, i leave the computer connected to internet the whole night, no user interference and was online all the time...
something is the trigger..

Macbook can't recognize Airport Express!

Hi guys,
I have a Macbook Pro Retina 15" Early 2013 running Mavericks 10.9.1. My router is the Apple Airport Express A1088 and what is happening is: I did the setup of the Airport Express last year and everything was working fine. I had to download the Airport Utility 5.6 and then I configured the Airport Express. Alright. But today, my wifi connection was not showing in my Macbook Pro, but it was working fine in my iPhone 5. I tried to turn the Airport Express off, and the same for my Macbook Airport, but it doesn't work. So I decided to do a hard reset and also a reset to factory settings. What is happening is my Macbook Pro showed only one time after doing the reset and I did all the steps of the setup using the Airport Utility 5.6. But when the airport express restarted, it was working only with my iPhone 5, not with my Macbook. So I tried to reset again to factory settings and now I can't do the setup because the Airport Express doesn't show up in my Macbook as a new base station or anything else. With my iPhone 5 I can see the Airport Express as a new base station, however I am not able to setup it because it is a old version (A1088).
I don't know why my Macbook Pro is not showing up the Airport Express. I have already tried to make it work with Windows (via virtual machine) and using Airport Utility 5.6. I also know that THIS IS NOT A HARDWARE PROBLEM! Any other network I am able to join with my Macbook.
I also looked in this forum about other users that had the same problem, but almost all of them started working after a hard reset or reset to factory settings, which is not working for me.
I just wish my Macbook to recognize the Airport Express, until yesterday everything was working fine. And today it is only working with my iPhone, but I am not able to set up it with the iPhone.
Help!
Thanks!

Hey Luis!
I am sorry - i only searched for Apple Airportutility and Mavericks to post the Link :-)
Did you already tried
- to delete your Wifi from the list of known Wifi's from your MacBook/System Prefs/Network/AirPort/Option/
- or maybe delete and reinstall the AirPort Service from your MacBook/System Prefs/Network
Cheers

AirPort Express Network Running Slow

I am running an AirPort Express network in my dorm room with my MacBook Pro. Things were going well, but as of late, it seems like it is slllloooowwwwing down. I cant even get through a 30 second iTunes clip without the "Network Stall"ing at least twice. Webpages take a while to load and that new iPod tutorial video, yea, had to go to class and come back before the SMALL one was ready to play straight through.
I have reset the airport express, renewed the DHCP lease... I think I have to clear out something like the DNS or whatever... any ideas!?

More than likely you are experiencing RF interference. Try changing the channel used by the AirPort Express (AX) until you find a channel which works better or you run out of channels.

How do you add an Airport Express to an existing Airport Express network

I assume that you are interested in using the new Express to extend the wireless range of the other.
If so, please check out the following Apple Support article.

Ipad2 is no longer detecting ANY wifi networks.

Hi, my 9 month old ipad 2 no longer detects ANY wifi networks. Was always logged on to our own home router and in settings was always able to 'see' neighbours wifi - now nothing shows.Is this a hardware problem?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

Connecting Wireless Samsung BluRay Disc to Airport Express Network

I am trying to connect my wireless capable Samsung BuRay Disc Player to my Airport Express Network. The Samsung keeps telling me to check my IP Address, DNS Server, Gateway etc. I have tried to set it up using the auto option and using the manual option. Neither is working. How do I check that my IP address, etc. is correct for connection??

Welcome to Apple's discussion groups.
I looked at a manual for a Samsung Bluray Disc player. They seem to have left out an important capability: the ability to choose a wireless network and supply its password.
You may be able to use the WPS (Wi-Fi Protected Setup) capability, although that is said to be tricky between Apple and non-Apple equipment. Use AirPort Utility to put your AirPort Express into "manual setup" mode. Invoke the menu option Base Station -> Add Wireless Clients. Then follow the player's instructions for "PBC (WPS)". Use the AirPort Utility option "First attempt". The AirPort Express' status light will turn blue while it waits for a connection from the player.
I have no direct experience with this. All the above information came from the electronic book "Take Control of Your 802.11n AirPort Network" (http://www.takecontrolbooks.com/airport-n).
I have no relationship with Take Control Books other than that of a customer.

How many people can simultaneously share airport express network?

How many people can simultaneously share airport express network? I want to set up a wireless network in my classroom and need to accommodate about 25 devices.

The AirPort Express will only handle 10 wireless connections.
You will need to consider an AirPort Extreme....which will handle up to 50 wireless connections.

Using my Actiontec modem's wifi, it doesn't find my new airport express. When I use the new airport express network I created error message says ip address is wrong. Help setting this new airport express up

Using my Actiontec modem's wifi, it doesn't find my new airport express. Using the new airport express network I just set up it says the ip address is invalid. What can I do to overcome this blinking amber light and error messages?

You need to begin by configuring the AEX to Join an existing network (Bridge Mode.) You can then connect to it using Wi-Fi, but the AEX will not extend your existing network.
If you can connect the AEX to your existing router using Ethernet, then you could use it to Create a new network. Otherwise, if you want to extend your existing network you will need to get a Wireless Access Point - WAP - from a non-Apple product like D-Link.

How can I share my Internet from my iPhone to Airport express network?

How can I share my Internet from my iPhone to Airport express network?

YES you can! - Gotta love those "you can't" answers from people who haven't even tried. ;o)
Just have your Airport Express "Join" your iPhone. It will share your Internet connection through its Ethernet port. I currently have an AppleTV connected via Ethernet to the Airport Express. With this setup I have wireless Ethernet AND wired LAN connection. I can even AirPlay to the AppleTV and have Internet at the same time. Haven't tried a switch/hub but see no reason why it wouldn't work. This proves to be very useful to create a wired network with Internet from a cellular device without Ethernet.
