ADSL keeps switching between 'fast' and 'interleav...

Hello
I wonder if you could tell me if there is some reason why my line profile / ADSL latency keeps being switched between 'fast' and 'interleaved'. Everytime it is switched from interleaved to 'fast' I lose download speed. It has just changed again today and as a result my download speed has (according to my BT Home Hub Manager) dropped from 6.3MB (yesterday) to 3.2MB (now). Is it possible to have the line profile left as 'interleaved' so that I can enjoy the extra download speed ?
Thanks for your help.

  • MBP keeps switching between charged and charging

    After updating to 10.5.6 my MBP has started switching between charged and charging once the charge reaches about 96%. I've tried resetting the SMC but hasn't helped. I'm trying to calibrate the battery now but it is a very slow process since charging the last 4% seems to take forever.
    Is anyone else experiencing anything like this?

    Does trickle charging really switch between charged and charging at one second intervals?
    The 10.5.6 changes to the battery menu must have been more than removing from menu options then because I had to turn off the text the continuous switching between charged and charging became too visually distracting.

  • Display keeps switching between primary and clone.. I think.

    My laptop, Pavilion DM3, keeps switching displays by the screen blacking out yet the computer still running.  If a video is playing for example I can still hear the audio but the screen goes black.  Some little musical tone plays when it switches and sometimes I get a little notification box that pops up saying the optimal resolution for clone display is... or it will say the optimal resolution for the primary is...
    It's incredibly frustrating.  Sometimes it only happens once every few minutes and sometimes it happens once every few seconds.  I usually press ctrl+alt+f3 which works but it's annoying to have to keep doing it.  I took it to Best Buy and they reinstalled the drivers and said that should work and if it doesnt then the next step is to ship it off to HP and that could take weeks.  The problem is I'm currently in grad school and this is my only computer.  I can't go weeks without my laptop even if it means having my screen black out every few seconds.  Hopefully it really is just a setting or something or a software thing that I can fix myself with the help of you fine people.
    My laptop is an HP Pavilion dm3 with Windows 7 64bit.  Intel Pentium processer U5400.  Optimal resoolution is 1366x768.  Graphics is Intel HD Graphics(integrated I believe?)  4 GB memory, 500GB hard drive.  I've had the laptop may six weeks and it's been having the issues for about two weeks.

  • Sapmmc -  jstart.exe keeps restarting, switching between green and yellow

    Hi Friends,
    I installed the SAP core server ( as part of SAP convergent charging) , but jstart.exe and dispatcher-1 process in sapmmc are noticed keep switching between yellow and green. when the jstart.exe turns green (all process running) , dispatcher-1 turns yellow (waiting to start) and when dispatcher-1 turns green (restart-yes) , jstart.exe turns yellow (some processes running). Only for a small duration , they both remain green (may be during transition).

    HI,
    Import the SAP profiles in SAP transaction RZ10: Utilities - Import profiles - of Active Server
    OR
    Check what messages do you have in jvm_server0.out, dev_server0.out and bootstrap traces,
    also have a look at the note 142100.
    The first problem is that in the SCS instance there are no running enqueue server as its starting line have no line break at the end in the start profile. Without this NT cannot parse the line. After adding the line break the enqueue server could start.
    The second problem is that in the global dispatcher configuration for the LockingManager the en.port was set to 3201 instead of 3200 (which is correct as the SCS instance has the intance number 00).
    After correcting these problems the J2EE engine could be started fine.

  • My 3GS keeps switching between iPhone speaker and Dock connector and I don't know how to keep it on iPhone speaker

    My 3GS keeps switching between iPhone speaker and Dock connector and I don't know how to keep it on iPhone speaker so I can listen to my music and games.  Is it hardware or software problem?

    I was told by a friend that sometimes when you use a 3rd party charger that the connectors are not the same size and so it can affect the sensors in the phone and make it seem like it is in a docking station and so changes the output for dock speakers.  With that said, I didn't take my pohone in to be serviced at the appple store because it was a 3GS and over 2 years old and so not covered by any service plan.  Since then my phone is back to normal and I can use my headphones and listen with the speakers on the phone.  I stoped using the suspected cheap 3rd party charger and maybe that's what did it, but not sure if it was or wasn't the cause of my problem.  I'm glad that my phone is better I was kinda holding out for the Iphone 5 when i comes out later and hope my phone lasted until then.

  • Can't switch between  fill and outline.

    Here's the problem: I'm on an iMac, new, trying to use illustrator CS5. after using CS3 for a few years. In CS5, if I draw a shape, flat, in the illustration, then try to give it an outline, or change the outline, or do anything with the outline, I can't. If I click on the Shape tools in the toolbox and draw out an oval, for example, I can switch between outline and fill without any problems. Select shape, go to toolbox, select curved arrow for switching from one to the other. That's it. But if I draw a freehand shape, then try it, i can't do it. THIS IS A BIG CHANGE FROM PREVIOUS VERSIONS OF THE APP. GET IT? What is the problem? If it's something I have done, fine, tell me and I'll fix it. I tried calling Adobe support in Bangalore, and it took 30 minutes just to get the problem thoroughly appreciated by the techies. They just couldn't get the idea for half an hour! I had to go over it 4 or 5 times. And they couldn't come up with an answer. they were no help at all. I'm hoping the forum will yield better results. This is pathetic, guys. Your 90-day tech support is a worthless piece of crap, guys. The only tech support we have is this catch-as-catch-can forum. I've been using Illustrator since 1987, (illustrator 88) believe it or not, it's true. And I've always been able to get tech support to cure the ills. Not any more. Is that the way Adobe plans to offer tech support? if there were a way to contact Adobe Tech Support by going around Adobe Bangalore, i would use it. But, alas, I am stuck with this.

    Dear Monika and Mylenium: I figured out part of the problem, but not the solution: The shape I had drawn -and coudn't  switch between fil and stroke on-is one I had already done a gradient mesh on, too. I had later abandoned the gradient mesh by using the option key to delete mesh lines, but that didn't take the shape all the way back to its original flat state. So it wasn't a plain drawn shape any more. So how do I release the gradient mesh  to get back to  a flat shape? I'm also having trouble keeping the shapes in RGB or CMYK mode-they keep defaulting back to greyscale. Could that also be a symptom of using gradient mesh? Note: I'm using gradient mesh for the very first time now; I've never used it before. It seems to leave a lot of unexpected baggage behind. I would send a screen shot, but if I start up Grab or Voila, all the AI pallets go away, and that's half the information.  So how do I control gradient mesh?

  • Docked T500 - Switch between headphones and speakers

    Hey guys,
    I am using my T500 with an Advanced Mini Dock at work. I keep the headphones (with microphone) plugged into the docking station. 
    Sometimes I want to listen to the audio on my laptop's speakers rather than inside the headphones. Is there any way I can make this switch without unplugging the jack from the docking station. 
    I know that above the volume bar for some systems you are able to switch between headphones and speakers and also, up until ~1 month ago I was able to do this from the SmartAudio utility, but now I can't. I can just switch between SPDIF and headphones. 
    I am using Windows 7 64-bit and I have all the latest drivers and apps that come using the "System Update" utility.
    Please let me know if you have a solution for this.
    Thank you,
    Ciprian

    I'm pretty sure that the blame for this lies entirely with Microsoft and their stupid hardware-detecting W7 OS. Yes, it actually detects when you unplug the headphones, tells you what you just did, and promptly resets all sorts of things. The most sensible thing you can do (apart from reverting to XP, which doesn't do this) is to plug an external stereo jack to stereo jack socket extension lead, and plug either your headphones or speakers into that instead, whilst leaving the plug end permanently in the laptop. Microsoft can't pull that stupid stunt on an external connector, so you should be okay with that.

  • Switching between https and http requests

    Hi,
    Our application is built using ADF 10.1.3
    This application need to be integrated with an in house built single sign on system. ( SSO system is built in C# and .NET)
    This single sign on system only understand https request. Once user is validated against single sign on system, our application's authorization page is called in HTTPS mode. Once the user is authorized, he is forwarded to home page. While forwarding to home page, we want to convert the HTTPS request to HTTP.
    Currently once the user is authenticated, all requests are happening in HTTPS mode.
    We do not know how to make http request from existing https requested page.
    Any help is appreciated.
    Thanks

    Hi,
    the way to do this is by redirecting the call from a PhaseListener or command button.

  • Easy way to switch between Headphones and Surround in

    I'm looking for some sort of utility that can make it easier to switch between headphones and surround speaker setu
    ps.
    As it is right now, I use my headphones for FPS gaming and such but when I listen to music, etc., I want to then have XP go back to settings for 5. surround. I keep both my headset and speakers hooked up and just power off the speakers when I used my headphones.
    Is anyone aware of a utility that can automate this?
    At the worst perhaps just a tray icon that I can quickly select the desired setup but better would be a utility that watches the current apps and lets me tell it what the right settings are for each and change it on the fly.Message Edited by Agrajag on 0-08-200804:57 PM

    i don't know of any way to automate this process.... i have speakers and a surround sound system, but my computer is usually set to the surround sound setting. i just leave it like that when i use my headphones. the headphones work alright when the surround sound setting is on, as far as i can tell. hope this helps

  • Switch between CDMA and GSM Iphone 5

    Hi,
    I am wondering on the Verizon Iphone 5, can you switch between CDMA and GSM via a setting or is it still like the iphone 4s where you have to remove the sim card to switch back to CDMA?
    Thanks.

    A SOLUTION: cut another corner and insert the nano-SIM upside-down, and keep a SIM card ejection tool on your key ring or tape one to your phone's case or both.
    Adam, and anyone else who like us, was hoping that there were a software based method that would allow iPhone 5 users the option of toggling between Verizon (or other CDMA carrier) and whatever other SIM Card based GSM carrier we have inserted/installed into our SIM tray.
    For myself, I have a SIM card with the "Minutes" type of plan, specifically the minutes plan that gives 2000 minutes for $100, which is good for one year. This is my backup network. 
    Since I do not need a SIM for the CDMA network that I use as my primary network, my SIM slot is empty (I am not running LTE, only 3G).
    So, in order to be able to switch my handset from one carrier to the other, which would be most helpful in the event of a system failure on my primary carrier I can switch over to my "backup/gsm network; it would be very, very nice to be able to toggle between the two networks, (like in the old days where we could simply select either the 'A' {non-wireline} or the 'B' {wireline} carrier/network) by simply pressing a couple-few buttons.  It is funny to me to actually realize my old "Brick" phone actually had a feature lacking on my iPhone 5.
    This would have been great during hurricane Sandy when my Verizon service was (literally) dead in the water for several days.  And, there is always the possibility of a cell site going down on the primary network, again.

  • NetworkManager - switching between wired and wireless

    Hello!
    I’ve set up a new laptop with Arch and now have a question concerning NetworkManager. Is it possible in NM to switch between wired and wireless connections like it is with Connman (https://wiki.archlinux.org/index.php/Co … d_wireless)?
    So far it appears that NM only disables the wired connection when wireless is used but keeps the wireless alive when switching to wired.
    I have already looked for a corresponding configuration but couldn’t find anything that helps.
    Thanks in advance.

    Easy Mode:
    You can install the tlp-rdw package and edit the /etc/default/tlp configuration file which has an option that does that.
    Hard Mode:
    If you don't want to install a package and its dependencies, you can write your own script and put it in /etc/NetworkManager/dispatcher.d and have the NetworkManager dispatcher hook run the script (which is actually what tlp-rdw does but you don't have to install the tlp package as a dependency)
    Note: tlp is a power manager and if you have any other power managers installed it might conflict with them so be wary of that.
    Here is the wiki page on tlp https://wiki.archlinux.org/index.php/Tlp

  • My Mas Air keeps switching between applications

    Anyone has this problem? Since i upgraded to Maverick, my system keeps switching between apps without any interventions, i dont even touch the laptop and it does.
    Steve

    I will try this cause yes I am using Google Drive. Another thing I noticed doing more test is that in fact the switch of apps that is occuring is all link to the FINDER. this is the application that goes in the back and comes back in the front of other apps all the time. I moved it to my monitor and the switch occurs there, if I close or minimize it, all is good.

  • Can't switch between HDMI and VGA displays

    I have a new H430, with hdmi and vga ports. My HP zr2240w monitor permits switching between AVG and HDMI displays, which I would like to do. But when I plug in both cables (HDMI and VGA) only VGA will work. If I  switch to HDMI or make it the default display,  the screen freezes at the desktop background: no mouse, no taskbar etc. Is is possible that the D430 video card will not support switching between displays (on  a single monitor)
    thanks,

    Dear Monika and Mylenium: I figured out part of the problem, but not the solution: The shape I had drawn -and coudn't  switch between fil and stroke on-is one I had already done a gradient mesh on, too. I had later abandoned the gradient mesh by using the option key to delete mesh lines, but that didn't take the shape all the way back to its original flat state. So it wasn't a plain drawn shape any more. So how do I release the gradient mesh  to get back to  a flat shape? I'm also having trouble keeping the shapes in RGB or CMYK mode-they keep defaulting back to greyscale. Could that also be a symptom of using gradient mesh? Note: I'm using gradient mesh for the very first time now; I've never used it before. It seems to leave a lot of unexpected baggage behind. I would send a screen shot, but if I start up Grab or Voila, all the AI pallets go away, and that's half the information.  So how do I control gradient mesh?

  • 7344 servo motion switching between open and closed loop operation

    I have a custom end-of-line test system presently using a 4-axis 7344 servo controller to perform various functional tests on small, brushed DC motors. The system is programmed in C/C++ and uses flex motion functions to control the motor during testing. Motors are coupled to external encoder feedback and third party PWM drives running in closed-loop torque mode from an analog command signal. The system uses all four motion axis channels on the 7344 board to independently and asynchronously test up to four production motors at a time.
    In closed-loop mode, the system runs without issue, satisfying the battery of testing protocols executed by this system. I now have a request to add additional test functionality to the system. This testing must be run in open loop mode. Specifically, I need to use my +/- 10v analog output command to my torque drive to send different DAC output levels to the connected motor.drive while monitoring response.
    I do not believe the flex motion library or 7344 controller includes functions to easily switch between open and closed loop mode without sending a new drive configuration. I am also under the impression that I cannot reconfigure one (or more) servo controller axis channels without disabling the entire drive. As my system runs each axis channel in an asynchronous manner, any requirement to shutdown all drives each time I change modes is an unworkable solution.
    I am open to all ideas that will allow asynchronous operation of my 4 motor testing stations. If the only solution is to add a second 7344 controller and mechanical relays to switch the drive and motor wiring between two separately configured servo channels, so be it. I just want to explore any available avenue before I place a price tag on this new system requirement.

    Jochen,
    Thank you for the quick response. The 7344 board does an excellent job running my manufacturing motor assemblies through a custom end-of-line tester in closed loop mode. A portion of the performance history and test result couples the motor through a mechanical load and external shaft. The shaft is in contact with a linear encoder that closes my servo loop.
    My new manufacturing requirement is to also sample/document how the small DC motor behaves in open loop operation. Your solution is exactly what I need to perform the additional functional tests on the product I am manufacturing. I see no reason why this cannot work. I was originally concerned that I would need to reinitialize the 7344 board after changing axis configuration. Initialization is a global event and impacts all four channels on the 7344 board.
    Using flex_config_axis() to change axis configuration on a single channel without disturbing other potentially running axis channels will solve my concern. It will be several weeks before I can return to the manufacturing facility where the 7344-based testing machine is located. I will update this thread once I verify a successful result.
