Whenever data packets are transmitted via wifi, external speakers act like a geiger counter.

Hello all,
Very strange thing just started happening on my mac mini.
Whenever I download/upload content to and from the internet, my external speakers act like a geiger counter: the more data that is moving in either direction, the stronger/more prolonged the noise is through the speakers. And it is not specific to anyone application.
This DOES NOT happen when I open large applications on my computer. So it appears as though it is isolated to wifi transmissions and not internal processing.
Has anyone ever experienced this? If so...?
Thanks!

Try moving/rearranging the speaker wires and repositioning the speakers to see if that helps. If it does that wold indicate the wifi is interacting with the speaker wires.

  • Very slow data on iphone 5 via wifi or at&t network

    Data on wifi or the LTE network from at&t is very slow.  My old iphone 3GS on wifi is faster when comparing wifi and past tests using 3G.  Is there an issue wih the new iPhone 5 that is known and will be fixed? I was expecting blazing fast data on the new phone and it's slower than my 3 year old iPhone 3GS...  Please explain.
    Thank you.
    Joe

    My wife received her white 64 GB AT&T iPhone 5 from on September 26th (after ordering on the 14th from Apple) and she has had recurring problems with her data connections.  Specifically, it will find wifi networks and even connect to them, but then it will spontaneously lose connections and she'll get error messages out of the blue saying that she's not connected to a wifi network.  Also, while she often has 4 or 5 bars for her cellular signal, the LTE, 4G, 3G, or Edge indicator is often blank.  Sometimes, LTE will light up and she'll be able to download at super-fast speeds, but then other times it's just not available.  Also, the wifi indicator will show multiple bars (or waves?), indicating that there's a strong wifi signal, but the internet just won't work over it.  This will happen while I'm sitting next to her with my AT&T iPhone 4, just sailing away on the internet with no problems at all.
    SO, we took her phone to our local Apple Store in Troy, Michigan for a Genius Bar appointment.  The Apple Genius told me that he had the EXACT same problems with his new iPhone, so he exchanged it for another one, and that also had the same problems.  He thought there were a few things going on.  First, the LTE issue is a local issue for us here in the Detroit area.  AT&T just rolled out LTE here 2 weeks ago.  So, they are having a number of bugs related to the network being new and possibly a little premature.  He thinks the network will be better in the next few months, from what he's heard from AT&T.  The wifi issue he believes is a software problem, unique to iOS 6 and its installation on the iPhone 5.  Since the LTE thing keeps going on and off, and wifi keeps going on and off, the data connection on the phone is very unreliable at this point, and the phone is using a lot of power to try to maintain that connection, hence the faster battery drainage we're exeperiencing as well.
    The bottom line is that there was nothing he could do for me.  He wouldn't even let me TRY a phone replacement to see if it would be better.  His suggestion was for me to sit tight and wait for Apple software updates and for AT&T to improve their network.  However, I am scheduled to have my new BLACK 64 GB AT&T iPhone 5 delivered tomorrow (October 1st).  I will restore it from my iPhone 4 backup on my iCloud (like I did with my wife's) and I will se how it goes.  If that phone connects and works flawlessly while my wife's phone continues to have problems, then I will return her phone for a new one.  On the other hand, if my phone behaves the same way as hers, then I guess I'll follow the Apple Genius' advice.

  • Can I stream from iTunes via Wifi to speakers attached to another Mac?

    Hello!
    I have a 15" Powerbook running 10.4.10, and a 400mhz Sawtooth G4 running 10.4.10 and 10.3.9. I also have a wireless network, with the G4 connected via Ethernet to the router. I also have a very nice set of speakers currently connected to both machines with two audio cables (to connect to the Audio-out on each computer), and a Y-adapter at the speaker.
    Usually, when I use my Powerbook, while it's in the same room, it's across the room - running on battery and completely wireless - and I am too far from the desk to plug the speakers directly into the Powerbook. Thus, when I listen to iTunes, I must use headphones.
    Is there some way to use the G4 as a sort of "network speaker"? By that I mean stream sound from iTunes in my Powerbook across the WiFi network to the G4, which then plays it through the attached speakers. Think of it as a sort of make-shift "airport express" - I'll be using the G4 in the same way that iTunes will stream music through an Airport Express to a speaker set. If a solution will work under 10.3.9, even better - Panther is friendlier (less resource hungry) on that old machine than Tiger.
    Thanks,
    -Dan

  • IPhone Newbie beating a dead horse - Why are large data packets sent

    Has anyone got an actual answer or solution to the large data packets being transmitted from the iphones?

    What cell service do others in your area use?
    From ATT terms of service:
    3.2 Where and How Does AT&T Service Work?
    AT&T does not guarantee availability of wireless network.

  • Sync via wifi devices not listed in iTunes

    I have 3 iOS 5 devices.
    I attach each of them via the USB cable to my Windows PC and they are shown.
    I select "Sync via WiFi" and remove the USB cable and the devices are no longer
    shown in iTunes. I believe they are suppose remain in the device list until
    they are detected via WiFi they are not.
    I restarted iTunes, the iOS devices (1 iPhone 4S and 2 iPad 1 devices).
    Attaching a power cable to the device does not make them appear.
    They are all attached to the same WiFi network as is the PC.
    Any insight appreciated.
    J

    Shut down your router, iDevice and your computer.
    Restart ithem in following sequence:
    1.Router
    2.Computer, open iTunes
    3.iDevices
    Wait for a few minutes for iTunes to detect the devices.

  • Data packet not getting processed

    Hi SDN's
    I m loading data from one ODS to 4 regions , the source ODS is successfully loaded from der to the data targets the load is getting failed or taking loang time .
    upto transfer rules the data is successful, in update rules data packets are not getting processed
    kindly suggest solution, points will be assigned
    thx in advance

    Hi Katam,
    In the target ODSs go to the monitor screen for a particular request -> in the menu bar go to environment -> transactRFC-> in the datawarehouse -> give the ID and date -> execute.
    Check if there are entries in that. Usually this queue will be stuck and you need to execute the LUWs in the queue manually.
    if it says transaction recorded u need to execute it manually
    Please revert if any issues

    Hi,
    These HTTP calls can sometimes be disrupted by timeout errors:
    - ICM_HTTP_TIMEOUT
    - ICM_HTTP_CONNECTION_FAILED.
    How you can try to deal with those errors:
    1. you can try increasing the HTTP_TIMEOUT of the Integration Engine:
    a) go to TCODE - SXMB_ADM
    b) Integration Engine Configuration
    c) Change specific configuration
    d) Increase the HTTP_TIMEOUT parameter value - this value depends on your specific needs.

  • Data packets strucking in yellow

    Hi ,
    We are in BW 3.5. We have daily loads since long.
    Now a days hell lot of data packets are strucking up in yellow and we are puching them manually which is causing delay in availability of the data to users.
    We dont have any recent chnages in teh system adn we are in BW support pack 12.
    How can we get red of this?
    Regards,
    RajNi

    Sometimes the packets get stuck because indices prevent them from getting loaded properly.
    Go to performance tab of the cube ( what I a saying is relevant only for cube loads ) --> Create Index ( Batch ) - > there will be checkboxes to create and drop indices on load -> check both of them and then save -> it will ask if you want to transport the setting --> select no and then try doing the load.

  • Verizon Max Data Plans are not a deal

    I just read about the Olive Branch Verizon has extended to us obstinate unlimited data plan holders. 
    The Max Data Plans are a weed dressed up to look like an Olive Branch.
    I did the math on my unlimited nill vs a Max Bill with Edge phones.   Currently I pay $201.75 for two lines + unlimited data.
    I have an S4, so I don't need a new phone,  but if I did I would go Note 3.  My wife has an iPhone 5 64gb, so a 5s 64gb would be a good choice.
    After crunching the numbers and entering Edge would go up to 221.68 per month.   That's right up not down.
    Knowing this, why would I give up unlimited
    data?

    Michael,
    I am so tired of reading these Verizon forums, and seeing all these people who have been victimized by losing their unlimited data become Verizon's biggest defenders. Misery truly loves company. I don't care what they say, be it saving a few bucks for losing unlimited data (yet ignoring opportunity costs in keeping unlimited data OR even leveraging the unlimited data in other ways by utilizing "assumption of liability"), or praying for this magical day of July, 2014 when we're all supposed to lose unlimited data (which is complete and utter nonsense, forget speculation.) I thought that Verizon was supposed to be the one providing us a service, and not the other way around...though I suppose the Stockholm Syndrome folks enjoy that, I guess.
    Problem is there doesn't appear to be many people who have unlimited data offering information that would help people like us KEEP unlimited data; all it is are these people inundating these forums with misinformation and misery about losing unlimited data.
    So I will just tell you what I did to upgrade and hope that points you in the right direction.
    Recently, I did use the Device Payment Plan (different from Edge, which sounds like utter garbage) to get a Note 2. 700 divided by 12 plus $24 total. I figured why not; anything to get off this Samsung Droid Charge. Now, I am utilizing the alternate upgrade method, which allows me to upgrade a basic phone in my plan and switch that phone to the line with the Note 2, which I then will give the Note 2 to the wife, who also has an unlimited data plan. I probably should have done this earlier, but I initially thought it'd be too much work. However, after I did the math, even after activation fees and such, I still get a better phone at a better price than if I Device Payment Plan'ed it.
    I will let you know how it goes...I have three unlimited data plans that I can do a "transfer only" to get the hot new phones, and I plan on using anyone of them. And despite what some of you Verizon apologists say, I do not lose unlimited data when I transfer an upgrade to another line, which apparently, I can do THREE times...
    I am just sick and tired of seeing these people inundate folks with such bad information. Since this is a peer-to-peer forum where Verizon customers help each other, I figure let me help my fellow Verizon customers SAVE their unlimited data and also help lead in the ignoring of these bitter haters who just want other people to be miserable by having you lose your unlimited data plan.

  • Repeater does not forward data packets

    Hello all!
    I have following setup:
    A root access-point ap1, model AIR-AP1231G-E-K9 with IOS 12.3(8)JEE, is configured with one SSID on VLAN 1 (native) and working fine.
    Now I would like to add a 2nd access-point ap2 of the same model with the same IOS version as a repeater to extend the WLAN coverage of the overall network.
    I managed to configure the 2nd access-point successfully as repeater (same SSID settings, infrastructure ssid set, parent 1 mac-address set) and it associates successfully with the main root access-point.
    Now I observe following effect: As soon I leave the coverage area of the first AP and enter the area of the repeater, the client (iPhone, Laptop or any other WLAN device) associates successfully to the repeater (confirmed with "show dot11 ass" and due to the log entries of the repeater) but the data packets are not forwarded to the main access-point. There is no IP connectivity to the root AP or internet anymore.
    Another example which might lead to the solution is following observation:
    I have my laptop connected to the wireless network with two console sessions open. In one I run a ping to the first AP, ap1 (10.200.3.5) and in the other console I run a ping to the repeater ap2 (10.200.3.6). Both access-points reply.
    Now if I enter the coverage area of the repeater, my laptop gets associated to it and the ping to the first AP ap1 times out.
    Again, it looks like that the repeater denies to forward traffic to the main root AP.
    I have no clue why this happens, nor are there any log messages available which might explain this issue.
    I hope someone can help me finding the problem.
    The configuration of the working root access-point ap1 as the repeater ap2 is attached.
    Thank you!
    Best regards,
    Bernhard

    You  have configured sub-interface on radio interface & not in ethernet interface at Root AP end. change the config like below & see.

  • Upadating data packets serially

    Hi
    How to update data packets serially. It means one packet after another packet.
    For example i have a data flow, which updates data into PAS and then into Infocube which is serial update. But processing data packets , it's taking 2 or 3 data packets together and processing.What is the way to process data packets one after another.
    I have got an error when processing 8 data packets.First 4 have been updated sucessfully and last 2 have been updated sucess fully but 5 & 6 data packets have not been updated, got an error which is unknow error Where data is cleaned and in good format and every thing is pefect as first 4 and last 2 data packets.
    Thanks in Advance
    Sreekanth J

    Hello Sreekanth J,
    By design, each data packet can be processed independently. If two data packets are failing, there must be some reason behind it worht investigating. Check for short dumps of system log entries.
    If you still want to process one data packet at a time, then load data to the PSA and then from PSA to data targets. Processing happens in one background job one packet at a time.
    Again - not sure if the later option will ensure that hte data packets will go through. Also, try to right click on the failed data packets and select update again.
    Cheers

  • Sound panel cannot see external speakers

    I have a couple year old imac upgraded to 10.5.8
    I'm attempting to use external speakers via this path >> wireless to airport express >> optical to separate amp >> unpowered speakers. This used to work (maybe prior to upgrade to 10.5.8?), but now I
    can get it to work ONLY using analog link from airport to amplifier, but not optical, and ONLY for iTunes. Itunes lets me select internal and externals speakers using the little icon on the lower right.
    Video viewed via safari only allows internal speakers. If I go to preferences/sound/output it only shows the internal speakers as a selectable device. Could not find any way to add one so I assume if the system can't discover it you cannot add it.
    I reinstalled Airport and tried to reset the PRAM (?). Neither hurt but didn't help either.
    Any suggestions would be appreciated. I don't much care whether it's an analog or optical link to the amp, but I sure would like to hear internet sourced music via my external speakers.
    thanks

    I've tried each usb port and they still don't work.
    So these are the older type that connect using USB, and not the "II" version that connects using the mini-stereo jack? I ask, because I thought USB version does not work with the latest Mac OS X. I guess it must work, based on what you wrote.
    Since noticing this problem, have you shut down (powered off) the iMac and then started it back up? For hardware, shutting down is not the same as just restarting.
    Some sound-related settings are stored in PRAM, so you can try resetting PRAM

  • Airport Express - Movie sound on external speakers

    Is is it possible to hear itune's movie/radio via the external speakers that are hooked on the airport express. Music works fine.
    Thanks.

    I found this info given by rogue amoeba confirming my problem:
    http://rogueamoeba.com/support/knowledgebase/?showArticle=AirfoilVideoPlayer
    I think my issue cannot be solved, I just wanted that my whole computer sound environment can be played via airport express. I will still need a cable to hear the sound of youtube, etc.
    Very unsatisfying, I bought the Airport express because i thought it gives me a "one device solution". Marketing ********.
    Still, thanks for your help!

  • No sound from external speakers (MBP 13.3 2011). Please Help

    Hi. I bought the 13.3 inch MacBook Pro recently (Mac OS X 10.6.7). I want to play songs using my external speakers. But whenever I insert the jack of my external speakers into the audio-out port, there is no sound coming out of them. I searched for the problem on internet, but was unable to rectify. Internal speakers of MBP work fine. I've checked the basic things:
    1. External speakers are powered on.
    2. Sound is not muted.
    3. They work fine with my Windows desktop PC and with my TV.
    When I opened my Sound Preferences with having the jack inserted, under the Output tab I've this information:
    (Name)Digital Out     (Type)Optical digital-out port
    The selected device has no output controls.
    Also the volume setting is disabled and I can't increase or decrease the volume by dragging the slider (though the level is 100%).
    Please Help.
    Thanks.

    Oh yea, I forgot. I did rest the pram. So, I have done everything that any seasoned mac user would do. I speculate that this could be something to do with BootCamp. Just a guess. IDK

  • EXTERNAL SPEAKERS DON'T WORK

    External speakers don't work. They are LABTEC LCS 2420 speakers. The internal speakers with RealTek driver works fine. I have an HP Pavilion 23 touchsmart All-In-One PC with windows 8. I plugged the speakers in the headphone port then tried the audio jack in the back with the same resullt. When I right click on the sound icon and click on playback devices and riight click  in the open area i checked  show disabled and disconnected devices only the speakers realtek icon appears. Do I need to download other drivers and how should I do this?

    Try the following: Control Panel > Hardware and Sound > Manage Audio Devices > in the 'Playback' tab you should see the ports (rear and headphone) > R-Click the one that you are using for your external speakers and make it the default device.
    Trust this helps.
