Airport Express short circuit A1264

Hi,
The Airport Express model A1264 at my inlaws stopped working all of a sudden last year, for now apparent reason. They bought newer version, but I kept the old one. Cleaning my closet and pondering to throw it away, I decided to take it apart. To my surprise I discovered burn-marks of a apparent short-circuit.
Anybody else had this experience and should I report this?
Thanx.

The power supply inside the AirPort Express failed....a somewhart normal occurence if the Express has been in use for several years. I rarely got more than 3 years use out of the older version of the AiPort Express. Some users do better, some worse.
The newer version of the Express....introduced about a year ago....runs much cooler, so hopefully it will have a longer average life than the older versions.

Where can I purchase a replacement CD for the Airport Express Base station A1264?

Where can I purchase a replacement CD for the Airport Express Base station A1264?
I'd like to sell my Airport Base Station, but I believe I need a CD with the software on it for the new owner. Anyone know where I can find one?
Thanks!
Meredith

I doubt it is available.. and since a new Mac doesn't even have an optical drive.. there is no need whatsoever today for the cd.. it is all available in the OS or download. In fact the stuff on the cd will now be totally out of date.

Airport express base station a1264 was working great.

Hi
I have airport express base station a1264 and it was working great. Updated to Maverick and the utility now is 6.3.2. It seems now itunes drops occassionally.
I only want this AX to be a remote Stereo connection for my itunes. NO INTERNET
Connection goes as follows: Mac Mini Wifi to AX ---> Toslink to Cambridge Magic Dac100 to RCA to Pre-AMp. All was great for a couple of years.
Now it drops - annoyingly so!
I tried to update the firmware and then tried to re-configure but I can't seem to get it to ignore INTERNET connection.
It seems to work - but the MAC MINI has the exclamation over the WIFI icon - says no internet connection - which I don't want. Why is it looking for internet. I set up a new network and set the SSID as STEREO WIFI which itunes will connect to....
Do I care about the exclmation point? Never saw it - ...
THanks
Merry Christmas

This was working a week ago. I unplugged it for a move and now I get nothing. No light - it's like it's not connected to the power.
Locate the reset button, which is a small, circular gray, flush button near the connectors. (See the diagram on page 7 of this manual: http://manuals.info.apple.com/enUS/AirPort_Express_SetupGuide.pdf .)
Press in on that button while you plug it in. Continue to press for maybe 20 seconds. If you don't see any sign of the status light flashing during that time, then your Express may be dead.

Pl/sql boolean expression short circuit behavior and the 10g optimizer

Oracle documents that a PL/SQL IF condition such as
IF p OR q
will always short circuit if p is TRUE. The documents confirm that this is also true for CASE and for COALESCE and DECODE (although DECODE is not available in PL/SQL).
Charles Wetherell, in his paper "Freedom, Order and PL/SQL Optimization," (available on OTN) says that "For most operators, operands may be evaluated in any order. There are some operators (OR, AND, IN, CASE, and so on) which enforce some order of evaluation on their operands."
My questions:
(1) In his list of "operators that enforce some order of evaluation," what does "and so on" include?
(2) Is short circuit evaluation ALWAYS used with Boolean expressions in PL/SQL, even when they the expression is outside one of these statements? For example:
boolvariable := p OR q;
Or:
CALL foo(p or q);

This is a very interesting paper. To attempt to answer your questions:-
1) I suppose BETWEEN would be included in the "and so on" list.
2) I've tried to come up with a reasonably simple means of investigating this below. What I'm attempting to do it to run a series of evaluations and record everything that is evaluated. To do this, I have a simple package (PKG) that has two functions (F1 and F2), both returning a constant (0 and 1, respectively). These functions are "naughty" in that they write the fact they have been called to a table (T). First the simple code.
SQL> CREATE TABLE t( c1 VARCHAR2(30), c2 VARCHAR2(30) );
Table created.
SQL>
SQL> CREATE OR REPLACE PACKAGE pkg AS

The F2 function is never called. What we have NOT seen, however, is PL/SQL exploiting the freedom to re-order these expressions, presumably because on such a simple example, there is no clear benefit to doing so. And I can verify that switching the order of the calls to F1 and F2 around yields the results in favour of F2 as expected.

Airport Express Shorting Out

I have 2 Airport Expresses both with interesting problems.
The first is less than 5 months old but out of warranty (it was a replacement) and when I plug it in, the green light flashes for a second and then turns off (leading me to believe it's shorting out). Is there a way to open it up and fix this problem?
The other Airport Express is much older (4 years) but still works. However, if I bump it at all, it shorts and resets itself.
What is the deal with these things shorting out so easily and how can I fix it? Any ideas?

I'm sorry I am no help, but I want to document this in case someone else is searching for info in the future.
I don't know for sure if Airport Express is blowing my receiver or not, but right now it is the best guess. I had it hooked up for years and one day my dvd/stereo lost all sound. The power still worked and DVDs had video, but I had no audio.
I bought a replacement, hooked it up, and within a 30 minutes the exact same thing happened. No audio, but video is fine. I haven't fully diagnosed the problem, but as a test I'm installing another system and leaving the Airport Express unhooked. If nothing bad happens, I will assume (hopefully correctly) that something went wrong in the AEX and that caused the problem.
I will respond to this in a few weeks if this seems to be the situation in case someone else is having a similar problem.

Airport Express 1st gen A1264 can't be seen in Airport Utility 6.3.2 in OS X 10.10.2

I have acquired a 1st gen 802.11n airport express base station and I am trying to set it up through Airport utility but no matter what I try It won't recognize the device. I am using a 2014 MBP w retina display, 2.8 GHz Intel Core i7, won't be get picked up on my iPad Air 2 either.

Power up the AirPort Express for a few minutes
Hold in the reset button on the Express for 10 seconds, then release
Allow a full minute for the Express to restart to a slow, blinking amber light status
On your MBP, click the WiFi icon at the top of the screen
Look for a listing of New AirPort Base Station
Click on AirPort Express to start the setup wizard
If you are using an iPad, tap Settings on the Home Screen
Tap WiFi
Look for a setting of Setup a New Base Station
Tap on AirPort Express to start the setup wizard
If you have already tried this a few times, and the AirPort Express does not appear, then the AirPort Express is defective.

Unexpected error when connecting Airport Express A1264 to Airport Utility 6.3.1

My current wireless setup is and has been the following: Phone Jack --> DSL modem ---> Airport Express via Ethernet cable
Off of that connection we've been able to wirelessly run our MacBook, Apple TV and iPhones for several years.
We recently left for vacation, so I unplugged everything (apparently a huge mistake). When we returned from vacation, the wireless connection was intermittent and kept being dropped.
If I connect the Ethernet cable directly from the modem into my MacBook the internet works fine.
I tried refreshing the Airport Express by unplugging it and cycling it through. It continued to drop.
By opening the Airport Utility, a firmware update was recommended. However, since that update the Airport Express isn't detected anymore.
I tried a hard reset and Utility finds the Airport Express under "Other Wifi Devices" but then, at the end of trying to "Join the Airport Express to the Network" I get an "Unexpected Error" message.
Airport Express Model Number: A1264
Airport Utility: 6.3.1
OS: 10.8.5
I am very frustrated and way out of my league here with understanding how this all works and what I can do to fix it. If anyone has any suggestions or expertise to offer, I would greatly appreciate it.
Thank you for your time,
Amanda

Hi AMM222,
"Unexpected Error" message with Mountain Lion and AirPort Utility 6.3.x. Hopefully this is just a matter of enabling IPv6.
AirPort base station not seen or "An unexpected error occurred" appears in AirPort Utility 6.3
http://support.apple.com/kb/TS4597
This can happen if IPv6 has been disabled. To enable IPv6 for your network interface:
Choose Apple menu () > System Preferences, and then click Network.
If a lock icon appears in the lower-left corner, click it and enter your admin name and password to unlock the pane.
Click your network service (Wi-Fi or Ethernet) in the list, and then click Advanced.
Click the TCP/IP tab.
Choose Link-local only from the Configure IPv6 pop-up menu.
Click OK.
Click Apply.
The AirPort device should now appear in AirPort Utility.
Thank you for using Apple Support Communities.

Short-circuiting boolean expressions

There is a term used in other languages to describe the behavior of compiled code which evaluates boolean expressions: short circuiting. Basically, it means that if a term in an expression determines its value, then following terms never get evaluated, since they are irrelevant. For example, I have noticed that this always works in AppleScript:
if class of x is not integer or x > 32 then . . . .
But this will throw an exception if x is something that can’t be coerced into a number:
if x > 32 or class of x is not integer then . . . .
It looks to me that the reason the first always works is that Applescript is short-circuiting, and therefore there is no attempt to evaluate the inequality if x is of inappropriate class.
Does anyone know if Applescript’s behavior is sufficiently well defined that I can be confident it will always short circuit? I know I can avoid the issue by breaking such expressions into separate, nested, if statements. If there is no such assurance that is what I will probably make a habit of doing. But I thought I'd ask if this is really necessary.

Hello
Short-circuiting is well-defined in AppleScript.

Old Airport Express Ethernet Port Usage

hi there
i have an older airport express (Model No A1264) bought some years back, it has only 1 ethernet port on it instead of 2 on the current model.
i understand the new model has 1 ethernet WAN port for modem, and the other LAN port for ethernet printer or computer.
my question is, the ethernet port on my old airport express is both WAN and LAN? or is it just a WAN port?
because i intend to get an airport extreme to hook up a optical fiber modem which will be located downstairs in my house.
and use my old airport express on the 2nd storey to hook up my etherenet printer, but not sure whether that ethernet port will work? or do i need to purchase the new model?
many thanks in advance

It no longer works.
Unplug the Express, let it rest a minute or two and plug it back it in.
Try a different Ethernet cable.
If still no luck, test the connection by temporarily connecting a laptop to the Ethernet port on the Express using an Ethernet cable that you know is working. Turn off the wirelss on lthe laptop for the "test" and see if you can get a good Internet connection that way.
If you can, you know that the Ethernet port is working, and you will need to focus your troubleshooting on the printer.
If you still cannot get a good connection during the "test", this indicates that the Ethernet port on the Express is no longer working, and the Express will likely need to be replaced.

I have the airport express as router can I buy the new airport express and use my old airport to extend my net?

I have the airport express as router can I buy the new airport express and extend my net?

Things can get confusing pretty quickly since there are 3 different versions of the AirPort Express.
If by "old", you mean you have Model No A1084 or A1088 AirPort Express (look at the label on the side of the device for the Model No), it cannot be used with the "Extend a wireless network" feature of other newer Apple routers.
If your AirPort Extreme is "square" shaped with rounded corners, then the "old" AirPort Express will not work with your AirPort Extreme using the "Extend a wireless network" settings.
You could use a "previous version" AirPort Express, Model No A1264 to "Extend", or the "new" AirPort Express, Model No A1392, for that purpose.
If your AirPort Extreme is a simultaneous dual band product, then the "new" Express would be able to "extend" both bands. The "previous" AirPort Express (Model A1264) would be able to extend only one band, since it is not a dual band device.

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.

AirPort, older AirPort Extreme Base Station, AirPort Express, Newer AirPort Extreme Base Station

This may sound like a fairly dumb question, but here goes anyway:
I have a 27" iMac with the following AirPort Extreme card:
Card Type: AirPort Extreme (0x168C, 0x8F)
Firmware Version: Atheros 9280: 2.1.14.6
For a Base Station, I'm currently using a pretty long-in-the-tooth M8799LL/A AirPort Extreme Base Station (with modem and antenna port)
I recently bought an Airport Express:
AirPort Express MB321LL/A (A1264) to
A. Use AirTunes to send iTunes from my Man Cave on the first floor at one end of the house to the family room on the first floor at the other, where it will connect to an A/V setup, and, probably, one of my USB printers
B. Act as a repeater for the AirPort Extreme Base Station, which is physically closer to the Man Cave than to the family room. My wife and I use our ancient-but-hangin'-in-there iBook G4s in the family room (and upstairs) to check email, eBay, etc. Both in the family room and especially upstairs, we sometimes get only 2-3 bars on the AirPort signal strength indicator in the menu bar.
I see that I can get, from a well-known third-party retailer, an AirPort Extreme 802.11n A1143 (1st Generation), for an exceptionally reasonable price.
My question is, what would getting the AirPort Extreme 802.11n A1143 do for me, if anything? I know it would give me one more signal source in the repeater chain, and I could probably put the Auld Nyle M8799LL/A in the stairway or upstairs to boost the signal upstairs, and I could use the USB port in the AirPort Extreme A1143 for connecting another USB printer or USB external hard drive (would this drive be available to any Mac on the AirPort network?)
Any other configuration possibilities and suggestions greatly appreciated!
Peace & Love
Bart Brown

Thank you for the prompt reply and the very helpful links. I'm going through all the support docs right now, but from your explanation and what I've seen in the support docs so far, it would appear that the maximum bandwidth is achieved by a physically-connected "Roaming Network."
I'm so out of it, I'm afraid I'd never heard of "Powerline adapters," but I looked them up, and I guess this is the system that uses "Romex" - style standard house wiring to carry signal, which cuts down on each individual Base Station's power overhead (does it also affect bandwidth?).
I see a lot of names selling these adapters -- Western, D-Link, NETGEAR, ZyXEL, Monster, Sling Media, PowerNet, Cisco-Linksys, Actiontec, Medialink, Rosewill, TRENDnet -- and a lot of different configurations: 1 port, 2 ports, 4 ports. Basically I have one 27" iMac that doesn't go anywhere (it's not too portable!), a couple iBook G4s, and a point where I want to run 1/8" mini-jack-to-RCA L/R audio cable from the AirPort Express to an A/V receiver. I doubt this configuration is going to change, as I'm 63, and too lazy to lug stuff around if I don't have to. What do you think would be the best solution for me, considering I just ordered the AEBSn and I already have a brand-new AXn. Should the 27" iMac, since it ain't movin', be connected by ethernet/"Powerline adapter", rather than relying on the internal Airport Extreme card? I guess what I'm asking is, given what I want to do, how many of these Powerline adapters, what kind (do you recommend), with how many ethernet ports do I need?
Thank you again for your prompt and informed help.

Airport express can't extend wireless network

Airport express(A1264) can't extend wireless network. It seems that Airport express can't find my home Wi-Fi network. Amber light is blinking, and AirPort Utility of MacBook also can't find Airport express.
If AE is connected with TC via LAN cable, amber light is blinking with message "Wireless Network" (This Airport base station is set up to join a specific wireless network that can't be found...)
It was successful only once, but all failed after that.
Is there solution for this problem?

Sorry, I misunderstood what you wanted to do.
Since you did tell us that you had the Express connected with an Ethernet cable, I assumed that was how you wanted to configure the Express.
But I want to extend a wireless network (not using ethernet)
Because Airport Express and Time Capsule cannot be connect via ethernet cable.
Follow the same setup as above....and do not connect an Ethernet cable.
Keep the Express near the Time Capsule for the setup. Once you have a green light, move the Express to a point that is about half way between the Time Capsule and area that needs more wireless coverage.
If you reset the Express several times and try the setup several times without success, I think you have to suspect a defective Express.

Airport Express and Verizon Fios - setup problem

we recently converted to Verizon Fios - the airport express (used to play music through a stereo) stopped working and is no longer recognized (continuous blinking amber with "no configured station etc")- i have read through older solutions and many deal with different versions of the station or of Airport Utility - my Airport Express is Model A1264 - the Airport Utility is 6.3.1.4 - the OS X is 10.8.3 -
the Verizon Router has the following: (codes left out)
Actiontec number (ending in rev.1 - is this the model #?)
User name = admin
password
ISSID
WPA2 key
WPS pin
Wan Mac
the ISSID (5 digitt alpha and numeric) and the WPA2 Key (16 digit alpha & numeric) have been used to log on all wifi devices in the house (eg iphone/ ipad, streaming netflix) and worked
any assistance greatly appreciated

i did read your post and had already tried a hard reset - several times - i have done it again to no avail - however i have done the following
- i have 3 iMacs - one in the next room to where the main one is (the one i am having trouble with) and another in another part of the house with no wifi service - i took the Air Exp and plugged it in next to the iMac furthest away - it was found in seconds
- i next tried it on the iMac in the next room - it was found - the Utility indicated it was examing the station then it wanted me to set up a new network which it named using my name and Airport Express - it asked for a new password - i gave it to it - THEN it wanted me to plug an ethernet cable into the airport express!! which i can't do - that is why it was being used wirelessly - i can't seem to get past that point
- the main Imac still will not find the Air Esp station - if i can get the one in the bext room to work the airport express i can transfer the music to it and play from there
