Airport Express audio cutout, even through ethernet.

Hi all,
I have my laptop wirelessly connected to my linksys router.
My airport express is wired to my stereo, and wired to my linksys router.
Music will very often cut out and give me a -3256 error. This is very irritating.
Help
Thanks,
Mark

What's more important than just the signal value it the Signal-to-Noise Ratio (SNR).
Since you already downloaded iStumbler, try using its Inspector feature (select Edit > Inspector from iStumbler's menu) to determine the SNR. Within the Inspector's Properties, note the values for "signal" & "noise." Start with your MacBook near the Linksys, note the readings, and then, choose the locations where you will typically use your MacBook to stream iTunes.
SNR is the signal level (in dBm) minus the noise level (in dBm). For example, a signal level of -53dBm measured near an access point and typical noise level of -90dBm yields a SNR of 37dB, a healthy value for wireless LANs.
The SNR, as measured from the MacBook, decreases as the range to the base station increases because of applicable free space loss. Also an increase in RF interference from microwave ovens and cordless phones, which increases the noise level, also decreases SNR.
SNR Guideline
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
If the SNR is 20dB+ at each of these locations, then you should be getting reasonable performance from your Linksys. If less, either try to locate the source of the Wi-Fi interference or try relocating either the router or your MacBook until they are within a 20dB SNR range of each other.

  • Airport Express Audio Via Home Stereo

    Hi,
    Ive got my Airport Express to play iTunes through my hifi system (after lots of swearing and stuff), but im really disappointed to see it doesnt seem I can play any other audio - for example if im watching tv online etc/any audio not coming for iTunes.
    Does anyone know if and how I can get other audio from my laptop to play through my stereo via airport express?

    Hello andygunner. Welcome to the Apple Discussions!
    Does anyone know if and how I can get other audio from my laptop to play through my stereo via airport express?
    Yes. You will need to use a third-party application, like Rogue Amoeba's Airfoil, to play audio sources other than iTunes through your AirPort Express.

  • Airport Express Audio Port Blocked?

    Hello all, I'm setting up my Airport Express to play music through my speakers. I've previously done this with no problems, but when I've come to set it up again, this time, the audio port isn't deep enough for the audio jack to fit in.
    The jack is a standard 3.5mm, and has been used with this Airport Express before.
    The port doesn't appear to be blocked (I can see the led at the bottom).
    There are no rattles and the Airport Express has been well looked after.
    Any idea what could possibly be causing this?
    Cheers,
    Ollie.

    I have had a word with my housemates, it would appear that one of them accidently snapped off the tip of a audio jack.
    How would I go about removing this? Is there an easy way to open the Airport Express? or should I take it to the apple store?

  • HT1515 do you need to connect the airport express to a router via ethernet or can it do it using wireless?

    do you need to connect the airport express to a router via ethernet or can it do it using wireless?

    There are 3 Apple routers....AirPort Express, AirPort Extreme and Time Capsule. Details here:
    http://www.apple.com/compare-wifi-models/
    Do you have one of these products in the living room? 
    If no, you can only use the AirPort Express by connecting to the router in the living room using an Ethernet cable at all times.

  • Airport Express audio: total washout?

    I just got a new Airport Extreme base station (I had previously been using a Linksys wireless router) and Airport Express and I'm having a very negative experience trying to use the latter with iTunes (which was the main purpose of buying it in the first place).
    The audio streaming from iTunes to the Airport Express doesn't play continuously. Instead, I get a few seconds of audio, followed by a few seconds of silence, followed by a few seconds of audio, and so on. It drives me nuts. When I first set everything up, it seemed to work more or less OK for the first few minutes, but then this problem cropped up and has only been getting worse -- now I'm lucky if I get 5 seconds of uninterrupted audio. When the audio drops out, the timer on iTunes stops advancing during the silence, then starts moving again when the audio restarts.
    Now the tech details:
    *I'm seeing this problem from both of my computers: an OS X G5 running 10.4.3 which is connected to the Airport Extreme base station via Ethernet and a Windows XP machine connecting to the network via wireless. Both are using the latest version of iTunes.
    *I'm using WPA authentication on my network, and allowing both B and G connections.
    *I've updated the firmware for both the base station and the Airport Express with the updates that were released today (1/4/06).
    Anyone have any ideas?

    Ok ... I retract my comment about 6.3. I'm not sure what happened but it eventually settled down. I did not have wireless phone or microwave operating when it happened, but I was using Bluetooth when it started (just in case that has an effect) but even after I stopped using Bluetooth, the audio was cutting out every few seconds.

  • Airport Express only outputs sounds through left channel

    Recently purchased a new airport express.
    Sound is only audible through the left channel. Sound through the right channel is barely audible even at max volume (speakers and iTunes).
    Speakers are fine (they work fine through the stereo, iPod earphones also only work through left channel).
    If I turn sound enhance on and up to high, I can finally hear through the right channel, but only at about 40-50% of the left.
    Is this a software issue, or bad hardware?
    I've hard reset the airport express multiple times. Same issue whether wirelessly or connected via ethernet. This is running from iTunes 7 for Windows using a Linksys router.

    Doesn't sound promising for the AX. Since it was
    recently purchased, do you have the option to visit
    your local Apple Store to either return it for
    replacement or, at least, have them verify the
    problem?
    The reason why I thought it might be software related was due to this effect of changing the sound enhancer, i.e by turning the sound enhancer on and setting it to high there was a considerable increase in sound output. If there was a loose connection somewhere I don't think I'd expect this behavior. It's almost as if the balance has been set all the way to the right.
    Given that no-one seems to have seen this problem before (other than a unresolved single old post on the Airport Express board), it does seem that you're right and the AX needs replacing.

  • Airport Express to play music through 20th Anniversary Mac?

    I'd like to be able to play music through the Bose sound system in my G3-upgraded 20th Anniversary Mac.  I've used a very early version of iTunes but it annoyingly pauses fairly frequently while playing for some reason.  Since I have an early Airport Express and have an Ethernet adaptor in the TAM I wondered if it's possible to connect the TAM via cable to the Airport Express and stream music from an iMac connected wirelessly to the Airport.  It seems a shame not to utilize the Bose speaker system for music.  Thanks for any ideas and suggestions.

    As far as I know this isn't possible. I might try some stuff using my TAM (although results may very, mine isn't a production model) to see about figuring something out. If the computers sit close enough together you might be able to run a 3.5mm(1/8") headphone cable between the iMac's audio out and the TAM's line in, that or make use of the FM tuner and listen to some awesome FM stations.
    Now that I think of that you can invest in something like the link I'll add at the bottom of this, connect it to the speaker port of the iMac then use the tuner on the TAM to tune into the frequency of it. This would also allow the connecting of something such as an iPod.

  • Airport Express Audio Drop and Network issue

    I have a Dell Laptop, DLink G604T router and Airport Express. When I first bought the airport express I successfully got it to join my existing Dlink wireless network and I could happily stream music wirelessly to the airport express and maintain a wireless internet connection through the Dlink router.
    Since then I started having issues with audio drops to the Airport express and despite doing a lot of searching on the discussion forums and internet and trying different things have never solved the issue.
    The one thing that does seem to work is if I create a new wireless network with the Airport Express rather than joining the existing Dlink one. I can then stream music flawlessly all day long. The down side is I then can't get internet access wirelessly at the same time. I have to disconnect from one network and connect to the other.
    If I connect the dlink router to the airport express by ethernet and use the Dlink router just as a modem I think the issue will be resolved but this is not convenient due to position of router and airport express.
    So the question is, Can I get the Dlink router to join the Airport Express Wireless network wirlessly rather than the AE joining the Dlink wireless network? Any thoughts on whether this is possible and if so how?
    Dell Inspiron 500m   Windows XP Pro  

    I had one AE base unit, where network connection would disapear every other day. The light would still be green on the AE, but the signal from the AE could not be picked up nor seen by the computer. Only turning the AE off and back on, would make it appear and work again. I Changed the AE unit, and I dont have the problem any more. I didnt change any settings at all.
    So in my case, it was the AE base unit that was malfunctioning.
    I have also seen similar problems with a different cause: That the wifi network card in the computer wasnt connected properly. ..
    I dont think its a software problem
    good luck

  • Airport (express) extremely slow wifi and ethernet speeds! Please help!

    Hello there,
    I am having some difficulty with my new airport express. Basically I got it to use while at university where they only have ethernet. It's like a hotel, once you connect to it you log in via a web browser.
    The issue is I plug it in, set it up to create a new wireless network, everything connects to it fine (macbook, ipad etc) but then the speed is HORRIBLE.
    I did a speed test on my iPhone (over wifi) and the down speed was about 10x slower than what it was connecting my laptop straight to the ethernet port on the wall.
    The laptop when plugged in via ethernet to the airport base station was even slower! Speedtest couldn't even load itself.
    I used to use my macbook pro and just share the connection with other devices I had, but I didn't like leaving it on near 24/7.
    I'm failing to understand why my macbook pro shares the internet fine with other devices, but the airport express cannot do the same (it shares it, but SUPER slow).
    Any tips would be appreciated. I've come here as a close to last resort .
    In bridge mode it shares the internet with any one device absolutely fine as well.
    Hopefully someone can help me out!
    Thanks,
    Tan

    Ha that's highly unlikely they can tell you have a router don't worry!
    Right so I figured it out after numerous attempts!! My internet is now super fast to all devices and no slow issues at all!
    What I did was to change the settings for router mode to 'DHCP and NAT' and although the airport came up with an error about double NAT, this is actually what we want. So you can click the ignore button.
    By changing it to NAT the router appears as one device on the uni network and the devices that connect to it are monitored soley by the router so they don't really appear on the uni network. This means that the connection that was previously split to three devices through one point on the uni network is now only going to 'one' device (router) which is then splitting the connection itself and so it's much faster!
    Hope that makes sense I know I haven't explained it very well...
    I've left all other settings as default in case you were wondering.
    Good luck!

  • HT201343 Apple Tv mirror + Airport Express audio output = How to?

    I want to mirror my MacBook to the Apple Tv but I want to send the audio to the Airport Express.
    If I ask my Apple Tv to send the output to the Airport, it works just fine.
    If, after that, I use the iPhone to mirror the screen and watch some video on youtube or Twitch, it works fine either.
    But if I use my MacBook Pro to mirror the screen, the audio output is sent to my TV through the HDMI cord.
    Is that any way that I can solve this?
    What I want to do is just mirror my MacBook screen with the audio coming out through the Airport Speaker.
    Thanks for any help, folks!

    Hi wennberginho!
    I have a couple of articles that should be able to help you with this issue. If you have a 1st generation Apple TV, you will want to reference this article:

  • Mavericks mirroring with airport express audio

    I am using a Macbook running Mavericks to mirror my desktop.  I am sending it to a projector connected to an AppleTv.  Currently the audio comes out only on the tiny projector speaker. 
    Can I stream the audio to a speaker connected to an Airport Express? 
    I have tried this but can not get the audio to work except when I play music in itunes.

    This is exactly what I would like to do as well. I have found a quasi work around through the use of the app 'beamer' on my macbook. It allows me to play movies from my macbook, sent to my projector via ATV, which then sends the audio to my AE.
    However I cannot get it to work with desktop mirroring. It seems like a bug/oversight on Apple's part rather than any big issue that requires complex solutions though....
    would be great if they could solve this.. *hint hint*....

  • Airplay Station OR Airport Express + audio câble?

    Hi,
    If i buy an Airplay Audio Station, will I need an Airport Express to broadcast music?
    Thanks

    The only base station with dial-up capability (in addition to traditional ethernet equipped modem capability) is the AirPort Extreme Base Station w/modem. Check the Apple Store to look over the details, and make sure you are looking at the AEBS with the modem (there is also a version without a dial-up modem which will not work in your application).

  • AirPort Express Audio Dropouts - Any assistance gratefully received!

    Yes, I'm fairly sure this is an old chestnut rearing its ugly head again but I haven't yet found a solution to my problem.
    I have a Dell laptop running Windows XP, a Vigor 2800 Router and two AirPort Express devices which seldom last much beyond three songs before intermittently dropping audio.
    It's a tad frustrating.
    Could any kind soul please run through the best things to check by way of a possible resolution.
    Many many thanks,
    James

    Aha! No I hadn't seen that article - thanks for that.
    I should have said I mostly get dropouts when I stream to two AirPorts simultaneously and I'm now thinking that the two wifi connections are interfering with each other.
    Either that or I need a more powerful machine!
    Thanks,
    James

  • Airport express - audio dropping

    i'm using airport express for wireless internet and to play audio through a pair of powered speakers. it has worked fine in the past but lately has been dropping the audio constantly. i'm playing music through itunes and the track just stops, and the audio ceases. i'm only about 1 meter away from the airport.
    any ideas? thanks!

    Same problem here. The audio drops seem to directly correlate with any and all web activity in Safari. Every time a new page has to load, Airport Express cuts out. I've had Airport Express (n) for a few months and only recently did this start happening.
