Interference Problems

I've had terrible interference problems since receiving my iPhone5 (both with static coming from computer and radio speakers if my phone is near), and with my bluetooth headset. I've tried multiple headsets (Plantronics Voyager and Motorola Sliver) and I can only get about 10-15 ft. from phone without having connectivity problems.  Apple even sent me a replacement phone but I had the same issues.  Any thoughts?

  • 4k@60hz big interference problem

    Hello.
    I have a 2014 MP with the D700 upgrade.
    I am using it to drive a 28" philips 4k monitor http://www.amazon.com/gp/product/B00K15LQZM
    In single channel mode (30hz) it works beautifully. However, when i enable displayport 1.2 on the monitor, there is interference on the right side of the screen. it is a regular pattern of noise (always the same degradation), and does not seem affected by moving the cable around.
    I bought the nicest miniDP->DP cable i could find which claims to be rated for 1.2, however after seeing the noise I decided to try another cable.
    This time I tried a 1.2-rated miniDP cable and a 1.2-rated miniDP->DP dongle. With this cable, the interference is ridiculous. the screen will flicker off and on, and the noise which was previously on the right side of the screen is now on both sides of the screen.
    Going back to the first cable restores the partially-degraded state, which is what i have to use when 30hz gives me a headache.
    Based on another post here, I have a hunch that this is some kind of EM leakage--though disabling wifi did not have any effect whatsoever.
    so my question is, are there any other radios which could be interfering?
    I have moved to a different house, and to another floor and side of my current house while troubleshooting this, and the noise is identical--seemingly ruling out ambient EM noise. I can't find any more 1.2-rated miniDP->DP adapters to try. I'm open to just about any ideas. I thought about bringing it to the mac store where i bought it, but they don't have any 4k/60hz monitors there for me to try.
    So far the $6k I've spent on this rig is under-performing the PC i bought for $400 5 years ago... hopefully someone can guide me to a solution or i'm basically done with apple lol

    I found this post buried in another thread. looks like this is a very common problem with the D700's. It seems like this is not a defect with my unit but a known bug with OSX display drivers.
    https://discussions.apple.com/thread/6080897?start=75&tstart=0
    basically the only way to "fix" this is by hacking a custom display header file which tricks OSX into thinking the monitor's native refresh rate is 50-56hz instead of 60hz. I'll update after i've tried this.
    too bad apple doesn't seem to care about quality issues... this bug has been open for a year and no one in support seems to have any clue how to mitigate, let alone fix it. Good thing for hackers.

  • Audio Line In interference problem

    I'm using my macbook for Garageband for recording and all was well until last night... now when I connect any 15mm jack to the line in I get noise, regardless of whether the other end is plugged into anything or not. If I reduce the input volume to ~20% I get a pulsing effect from virtually zero to off the scale about three pulses per second... If I drop the volume down further the noise stops.
    I've not changed intentionally changed anything on the software / hardware / leads anything. All I've done in the meantime is surf interweb, check email and backup once using time capsule.
    Any ideas?
    Cheers
    Pedro

    The headphone jack on the MacBook is a combination analog and digital port. When it is in digital mode you'll see a red light shining out of it.
    Mine is intermittently switching itself to digital, which makes a popping noise in my speakers and cuts off my audio. Very annoying, and apparently very common.
    In the system preferences I can see it switching back and forth between analog and digital when this happens. I wish there were a way to turn off the digital out in software, but I haven't found a way. I'm about to rip it apart and desolder the little switch that sense when a digital cable is inserted (which is what is falsely sensing the presence of a digital cable and causing this).
    Anyone home at Apple? This is a very common problem and I've yet to see it addressed. All I'm asking for is a checkbox in system preferences that says "Ignore the poorly designed switch in the headphone port?".

  • Problem with wpa and hidden ssid

    hi,
    I have a powerbook g4 (1,67ghz). i am having trouble connecting to a netgear router mr814 v3 if i use wpa and hidden ssid, i get a message, that the router would not support wpa!
    there is no problem with wep and hidden ssid or wpa with no hidden ssid.
    is also have no problems with wpa and hidden ssid with an ibook.
    the problems occur only with the powerbook with os x 10.3.9 as well as 10.4.2. even after the recent airport update, no change.
    thanks for the help,
    ben

    I would use WPA and broadcast your SSID.
    It use to be useful, but closing your Airport or wireless network (sometimes referred to as not broadcasting your SSID) is really no longer a real option when it comes to wireless security.
    Unfortunately "Closed" networks, MAC access control lists, and reduction in transmission power are all more "feel good" security rather than real security. All these various approaches are dated and mistakenly lead to overconfidence.
    WPA is your friend if you value wireless security.
    My recommendation is not to worry about broadcasting your SSID but use WPA. This will be more secure than a closed WEP encrypted network. Closing your network makes it very difficult for neighbouring networks to see which channels are free thus causing potential interference problems.
    Another thing to consider is that a closed network is still broadcasting and therefore is detectable (regardless of whether it is broadcasting a SSID). If someone was determined to hack into your network, then not broadcasting your SSID and MAC address access control is not going to stop them.
    WPA is virtually uncrackable (only really vunerable to a dictionary attack if a real word is used as a password) and therefore will stop the casual user and the determined hacker.

  • "Rolling" interference on DVD player

    I've run out of ideas so hoping somebody here can think of something I haven't tried.
    The office just bought a new DVD player (Panasonic DVD-S53) and VHS (JVC HM-DT100) to transfer video/audio to FCP. Both replaced previous models that needed to be retired. Both are going into a Comprehensive Video Group CVG-4X4s vertical interval switcher.
    Here's the problem: the DVD player is having some sort of interference problem that is causing a rolling video 'artifact.' We've tried everything we can think of. Switched cables, switched it from SVHS to regular video out, moved the DVD player away from all electronics, plugged it into another surge protector. Moved the Switcher
    It only is affecting the DVD (the output of both goes from the Switcher via the same cable and the VHS looks perfect).
    Any other suggestions?

    Huh...other threads have said that using things like MPEG Streamclip or Cinematize will make footage look worse due to the whole 'uncompressing/estimating of missing frames' thing...so who knows what to believe?
    Unfortunately need to use DVDs sometimes...some publicists only have B-Rolls on DVD, actors need Demo Reels, etc. etc. etc.
    Seem to have figured a work-around (having it go directly to the Sony DSR-45 instead of the switcher...causes a few more steps, but the interference has all but vanished. Still don't understand why the DVD player is the only device affected but...there you go!)

  • How to prevent interference between multiple Kinect v2 sensors

    Hi,
    I have an application which used to use 3 Kinect v1 with partially overlapping field of views to have a large field of view of a scene. I am trying to upgrade this application to be able to use 3 Kinect v2, as the Kinect v1 is now discontinued.
    I am having problems dealing with interference on the depth stream. Every now and then, the light from one of the Kinect will give bad readings on another Kinect... This is not new, the Kinect v1 had interference problems too.
    To solve the interference problems with the v1, I used to simply toggle the IR emitters ON and OFF. Since my 3 Kinects don't need to acquire a frame at the same time, 2 of them would turn their emitters OFF and the one Kinect that would need to acquire a
    frame would turn its IR emitter ON.
    Now, since we can no longer control the IR emitter directly, can any one give me a good solution for preventing my Kinects from interfering each other ? My Kinects don't need to acquire a frame at the same time, but they may need to each acquire a frame
    on a short interval (about 100ms), so closing and opening the Kinects is not an option as up to 2 seconds can pass between the call to KinectSensor.Open() and the first non-null depth frame.
    Thank you.

    I've been pricing builds on Newegg that I could turn into a small Kinect cluster.  I need three for what I want to do.  this is what I have right now.  It's going to be a while before I can build up three grand so I don't know if I'll ever
    get to do it. But on the bright side I would be able to use it as a cluster for other projects as well, so...yeah.  I was thinking i5 but the linked conversation is deterring me from that. Would you be willing to let me know some more of your system's
    specs? Would love some input from anyone willing to offer any!

  • Refresh rate problem with external 20 inch acer

    I am having issues hooking up an external montior via the dvi to vga dongle. The refresh rate seems shaky and the only refresh rate the computer gives me is 59.9 ?
    I recently had my logic board replaced and am not sure if this was an issue prior.
    thanks in advance.

    I've isolated the issue only happening when using taxing apps like photoshop. Seems to happen when the fans kick in.
    could this be an interference problem or possibly heat isssue?

  • Interference over VGA?

    I have a Sony Bravia next to my iMac, I used to output via DVI to a secondary monitor when the imac was in another room, however the Bravia doesn't support DVI only VGA.
    I bought a miniDVI to VGA cable from the mac store, and connected everything up, including the audio. However, the audio is creating severe interference to the picture with horizontal bands.
    I've had a PC, mac mini and even dreamcast hooked up to my TV before with no interference problems of any kind, via VGA and an audio cable. I am using the same cables actually.
    So I am wondering; is it the miniDVI cable at fault or my iMac it's self?
    I'm totally fed up of buying cables from the mac store, seeing how the miniDVI to DVI and DVI to vga are INCOMPATIBLE (even though they are both mac products)

    guess I'll take the cable back then

  • 2511x refresh rate problem

    When trying to use a particular piece of software I get an error saying that I must change my resolution to 1920x1080 @60Hz.  when checking in my display and video card settings this is already the case, but when viewing the OSD is is showing as 1920x1080 @58Hz.  I reinstalled the drivers and rebooted and no change.  What can I do the change this?

  • Major interference issue.

    Whenever I am trying to record audio, or play audio through anything other than a passive output, I get a high pitched buzzing/popping sound. I set about investigating what in my room was causing the noise using a microphone, and whenever the microphone was placed in the vicinity of my trackpad, the microphone's induction coil went nuts and starting picking up the very same interference that I was picking up when trying to record.
    I can guarantee it was only the trackpad, because it only happened when the microphone was within a centimetre of it, and no matter where the laptop was placed. Is there any way I can temporarily cut off the power to my trackpad to stop this interference problem while trying to record? (I have tried using the disable switch above the trackpad, it does not affect the interference.)

    Hi there,
    I bought a brand new Dv7 the other day that is a bit higher spec than yours but I have a similar DPC Latency issue that causes pauses in audio and freezes in the system. I downloaded a DPC latency checker and began the process of narrowing down the the culprit causing the latency. Turns out my WiFI card (Ralink RT5390) was the culprit as when I disabled the adapter in device manger my DPC Latency returned to normal levels.
    After ding a little bit of searching I found that supposed solution is to download the latest drivers for the WiFI adapter as well as the latest BIOS update and just for safet's sake the latest audio driver too. I did this and I had no real change. Before you blame the AC adapter maybe you should go through the same process. Perhaps look at your power management settings and see if the wireless card is disabled when the machine is not plugged in? As that would make sense with my issue.
    It is of course possible that your AC Adapter is causing your issue but mine is definitely coming from the WiFi Adapter.
    Wis I could be of more help. 

  • Zen Micro Firmware Upgrade 1.01.03: Problems when Downloading and Installing the Upgr

    Yesterday I downloaded the new firmware upgrade .0.03 to my computer without problems. I then attempted to open the upgrade and initiate transfer to my Zen Micro unit through my USB 2.0 cable. I kept getting a dialog box, informing me that there was an interference problem... So I shut down my Norton anti-virus and my Zone Alarm firewall, and tried again, and again, and again. I was unable to initiate the transfer program...
    I was about to contact you this evening for advice, but I decided to first switch my USB cable to another connector and try one more time. Surprise! It worked... A rather long connection, but the upgrade is now in my Zen Micro unit, just where it's needed...
    I've had my USB cable connected to what I believe is a USB 2.0 connection on my computer, and I often see the "not connected" dialog box. Each time this happens, I disconnect the cable from the Zen Micro unit, then reconnect it... Bells and whisltes sound, and I'm connected again, until a few minutes later I get the "not connected" dialog box yet again... Is this a normal procedure?
    Now, tonight I plugged the USB cable into what I've always considered to be a slower USB connection point... Mybe that's why the transfer took so long? But it stays connected indefinitely... no "not connected" dialog box.
    I've been having other transfer problems through the USB 2.00 connection point. I downloaded 23 tracks to my Zen Micro yesterday afternoon, and three of the tracks didn't make it... Frustrating as hell...
    I'd appreciate any comments from my peers, since everyone here has more experience than me...
    kooch

    koochiching,
    Try turning off the Media Sniffer feature from MediaSource and try updating the firmware again.

  • Aironet 1400 Interference?

    I have an Aironet 1410 which has been online for the past 3-4 months with no problems at all. The other day we noticed these messages coming through (I have removed mac addresses and host names).
    16 Jul 1 11:42:22 Warning Packet to client HHHH.HHHH.HHHH reached max retries, removing the client
    16 Jul 1 11:42:21 Information Interface Dot11Radio0, Station <wireless-bridge> HHHH.HHHH.HHHH Reassociated KEY_MGMT[NONE]

    16 Jul 1 11:42:08 Warning Packet to client HHHH.HHHH.HHHH reached max retries, removing the client
    This message then keeps repeating, and the link is almost unusable with regular timeouts to users and access to the remote 1410's web interface. Yesterday the messages stopped and the link is now as stable as it was before. Is this is an interference problem and is there anything I can do about it? I tried rebooting both devices and they switched to a different frequency (they are set to Least Congested Frequency) but this made no difference.

    The message indicates that AP has failed to reach associated workstation over radio and therefore it (AP) deassociates workstation. The reason for this, apparenly, is reachability of workstation over Radio. Can you make sure that your workstation is in the good area of signal strength and quality? Also make sure that there's no nearby AP which has overlaping adjacent channels with the AP in the questions.

  • Problems with AIM on new iMac G5

    Hi--Sorry if this is in the wrong place. I'm having an extremely frustrating problem with AIM, which I recently downloaded on my son's new iMac G5 (TIger 10.4.3). I've tried posting this question in the iChat forum, but since he doesn't use iChat and never has it open on his computer, I don't think it's an interference problem with iChat.
    AIM quits unexpectedly and repeatedly, often several times in just a few minutes. I've tried: throwing out all preferences, trashing and reinstalling AIM, and using AIM from a different user account on the machine. AIM worked FINE on my computer--an older G4 also running OS Tiger, so I can't imagine that this is an operating system conflict.
    A friend suggested that it might be a problem with the wireless network. The new G5 is connected wirelessly via Airport to my G4. Has anyone heard of AIM not running well on a wireless machine? Could something (an outside frequency perhaps?) be interfering with the wireless connection, causing AIM to quit?
    Needless to say, AOL's tech support is completely unhelpful. Says they don't provide tech support for AIM.
    If anyone can help, or knows someplace I can find AIM tech support, I would GREATLY appreciate it! THanks!

    The best advice I can offer is to dump the AOL AIM client altogether, and use a third-party instant messaging application that supports AIM.
    For example, Adium X is a full featured IM client that supports AIM as well as many other IM protocols.
    It's very stable on Tiger, and it's light years ahead of the official AIM client from AOL.
    Try it out!

  • Could weak signal be a computer specific problem?

    I've read all of the other "weak signal" posts, and they all seem to be caused by an interference/distance issue. My problem seems to be particular to my iBook, as my roommate's iBook gets full signal anywhere in the same room as the express and at least half signal from across the house. Mine only gets full signal on top of the airport, half signal from across the room, and NO signal from anywhere else in the house. Also, this is true not just with our network at home; any other wireless signal comes in at half strength as compared to his on our "internet connect" meters. Wasn't until I had side by side comparison that I could confirm my personal shortcomings, but I had suspected for a while (wireless distance limit of 10 feet sure feels like the tug of a wire). I installed the airport card myself, while his came ready to go....did I screw up? Any ideas at all?

    You may have your answer and I am going to throw out some info. I was having a lot of interference problems and Apple stepped up and helped out. First, and 2.6Ghz wireless phone will interefere with your network. Second, The airport has to have a clean line of site with the airport wireless card. Apple said they are finding the signal is having a bit of trouble going through metal, past microwave ovens etc. I have a G5 under a desk trying to get past a 30" cine display. I had to do some fancy work-arounds. Also turn on "interference robustness". It will slow your transfer rate down a bit, but it has kept me networked with little frustration.

  • Dual band router will fix interferences right?

    So i got really bad download problems, and i think i narrowed it down to interference problems.
    Probably baby phones or a wireless 2.4ghz phone from my new neighbours.
    So if i get the WRT320N-EW Dual Band router and put it on 5.2ghz this should fix it right?
    Thanks in advance.

    Home wireless networks based on the 802.11b or 802.11g standards transmit their signal in a narrow radio frequency range of 2.4 GHz. Various other electronic devices in a home, such as cordless phones, garage door openers, baby monitors, and microwave ovens, may use this same frequency range. Any such device can interfere with a Wi-Fi home network, slowing down its performance and potentially breaking network connections.
    One benefit of the 5GHz 802.11a WLAN devices is that they are not vulnerable to interference from other devices, because the 5GHz frequency range they utilize is not used by any other devices (at least for now).
    On the down side, because of the type of modulation 5GHz wireless devices employ, their signals are more prone to be reflected and/or absorbed by materials in the home. This can have the same practical effect as active interference; that is, to weaken the signal, and reduce range and speed.
