How know if the router or modem cable is the problem with bad internet?

I have intermittent problems of internet home.  The internet goes out for very short periods, then back on several times a day. At various periods of time, usually in bunches up.  Then sometimes instead of being down for maybe a normal 15-30 seconds, it could last 5-20 minutes.  And there are also periods of hours sometimes where the speed is VERY slow.

When he is not at all working, Airport utility looks like in the following screenshot, with the orange Internet and other green devices.  Sometimes, it only shows the Internet icon and light, with nothing else underneath.  If the internet is very slow (and I mean really slow, like minute 2 page load or not at all), everything is green, including the Internet icon.

It is the Charter cable with a modem surfboard, connected to an older Airport Extreme (in mode not wireless) model, which is connected to three aircraft from the airport, you can see in the screenshot.  Everything works very well for 8 years, but these problems have taken place in recent months. I replaced since the cable modem for a brand new, I have reset the Airport Extreme to the factory settings and tried all sorts of other things.

It isn't the wireless aspect, because I can connect a computer to the ethernet jack and it has the same problems.

So here's what I want to know: is there a way I can tell if it's the Airport Extreme or if it's the Internet Charter being flaky?  (I know it's not the cable modem because it does the same thing that before I replaced it).  I just want to isolate the problem. I don't want to succumb to Charter calling again, as we think the run around, I'm going to forward all tech would come home, and they never admits to have flaky internet.

I bought a bolt of lightning to Gigabit Ethernet Adapter so I can plug my Macbook Air directly into the cable modem, without going through the Airport Extreme, but internet is not stay down long enough for me to access, plug it in and reboot the cable modem.   Frustrating.

Suggest that you connect the MacBook Air directly to the modem, connect the Mac to the Internet and keep an eye on the MacBook Air from time to time for at least one day complete.  A few days would be even better, if possible.

If the connection remains strong during your 'test', based on other information that you provide as...

connected to an older model Airport Extreme

and

Everything works very well for 8 years

The first thought that comes to mind is that life expectancy, on average, for airport routers is about 5 years. It's on food, on average, at the start of the descent position.  Momentary grave start occurring, and the drops will increase in frequency over time.

It is a bet of $20, but you might consider replacing the external power for AirPort Extreme see if that provides any assistance.  This does nothing for the internal power inside the airport of course components.

    It should do.  You use one of the buttons of pen maybe?  Just touching wheels with the pen with no buttons or modifier keys.  Press ENTER to close the selection.

    Personally I never use the lasso, Polygonal, but rather just the Lasso tool by using the ALT (Opt) to operate the Polygonal tool.  I also use the mouse instead of the Tablet for the selection of cutting edge.  It is a little too uncertain where the point will go when hovering the stylus above the image.

  • How to solve the problem with Windows Update on Windows 7 64 bit Home Premium SP1; Module Windows install encounter error 126, impossible to run/scannow sfs or TrustedInstaller. Help, please

    Hello

    First of all, thank you in advance for any advice for any help, you can offer.

    A week ago I noticed that Windows Update had a backlog of updates (30-40) as I had it value updates but let me choose whether to install them. As I tried to install, I noticed download election for hours but no visible progress in the taskbar and only a few updates installed on restart. Try to check the updates of similar results. I tried a number of solutions suggested here as a tool for troubleshooting Windows Update, but it made that seem to clear my list of updates to uninstall and make sure Windows Update has been under the impression that I had never checked the updates, apparently a worsening of the problem like today no update appeared and I encountered error 8007000D.

    I've tried other options like Windows system update readiness tool and tried to run the sfc/scannow System File Checker, but what who would not (cannot start service repair) I grew more and more worried. On recommendation from other forums, I tried also to start TrustedInstaller in command prompt, which does not. Unfortunately, I had run a Disk Defrag and clean-up recently which had been deleted and (unbeknownst to me) my last restore point. The root of the problem seems to be the Windows Modules Installer, which does not start when you are prompted in Services (error 126), something wrong with the registry may. So reluctantly, I tried to perform a repair installation using a downloaded iso, I burned onto a DVD (insured was also Windows 7 Home Premium 64 - bit SP1). However, even if it doesn't seem to work, it is constantly check for installation updates (unless this is supposed to last several hours?) or if I opt not not to check, it pass the compatibility check and then fail in the second stage (collection of files, settings, and programs). I tried several times, once in offline mode with my disabled (Norton) antivirus and once in clean boot mode.

    I don't know what other options I have. I would like to avoid a clean as much as possible installation, because my computer (HP laptop) still seems to operate normally (for the moment) outside the impossibility to install Windows updates (via Windows Update or directly from Microsoft, it seems), but I think it would just leave vulnerable more and more over time. Has anyone else had similar problems and has found a way to solve? I'm not a computer expert so any help would be greatly appreciated.

  • How to solve the problem with the BSOD errors of memory?

    Original title: Windows 7 BSOD "memory management".

    So basically, I made a similar post about 3/4 weeks ago and only received assistance to a certain extent.

    My problem is that I get a BSOD "memory management".
    Dumps are here for you to watch (you need to perhaps copy and paste the link in your URL):
    https://SkyDrive.live.com/redir?RESID=871E879B9D5671EC! 186 & authkey =! AL1N44iVMCM3JFw

    My OS is Windows 7 Pro.

    There are a few changes I made in recent weeks. Before, I had a Netgear USB wireless adapter and when I had that my PC had this crash at least once a day. But I now have a TP-Link wireless card. However, my PC crashes again every 3 days, no more and no less. Weird huh?

    Record PC hardware:
    Power supply 650W Powercool,
    Motherboard Asus M5970 Pro
    AMD processor with Six cores bulldozer 6100 3.3 GHZ
    Corsair Vengeance 8 GB 1600 MHZ RAM.
    Western Digital drive hard 500 GB.
    Western Digital 250 GB hard disk
    SAPPHIRE RADEON HD 7750 1 GB graphics card

    I also tried to buy the new RAM, but this did not improve the situation. I still had the accident itself, so I changed back to my old RAM and got a refund because the question is obviously not with the memory RAM (so please not a single mention to run the memtest).

    In addition, with the second disc HARD (250 GB) connected inside with my XP on, sometimes I hear it make a noise as if it is off, which is obviously because of the PSU not put enough power, I read about the BSOD memory management can easily be solved by upgrading the PSU and just want to collect some more experienced opinions before eventually trying this , I really don't want to buy a whole new PSU and then send it again that the problem is still happening (like I did with the RAM).


    I arrived at my own theory that perhaps I may need to lower the frequency of the RAM in my BIOS, or maybe overclock. If someone could help, it would be great. Thanks to all in advance

    The trickiest part is the every three days, not more not less. I shouldn't have overlooked than before.
    This could possibly come from a program that tries to access Windows or the
    Internet in this time (automatic update?). Perhaps something to do with your wireless network card, or even something like your anti-virus.

    "Hmm maybe it's the question then? the RAM is running at 1600 mhz, and even if my processor is a 3.3 Ghz, it is still running at 3.6 Ghz (even if I haven't myself)"
    Ooops sorry :) - looks like I got confused somehow your message with one using a Phenom 945.
    Your processor can execute with a max of 1866 Mhz RAM, but your mobo still has a 1333 Mhz max
    If the system is not what OC'd
    The 3.6 Ghz is "turbo" (auto overclocking) processor speed. If the speed of the cpu is still at 3.6 Ghz
    Perhaps because of the RAM being set at 1600 Mhz. If you set the RAM by default in the BIOS, it won't
    stop the cpu of the use of turbo mode when he needs extra grunt.
    It is also possible (I have not used a processor with turbo, then only speculate) the cpu OC is the RAM at 1600 Mhz in turbo mode.
    This could be checked if the speed of the RAM is the default value (which would be 1066 or 1333 Mhz)
    in the BIOS.
    The mini dumps have nothing conclusive. That there is a memory management problem. They suggest a possible driver conflict but cannot identify the driver.
    A possible such driver comes with Daemon tools. If you have Daemon tools installed, then
    the link below shows how to get rid of the driver.

    BSOD in the use of the high memory, fltmgr.sys - Windows 7-Forums

    A msinfo32 report is usually suggested to be included with the mini dump and can
    reveal something more.

  • How to solve the problem with slow import mxf files exported from first cc?

    Hello!

    I'm working on the first update to 7.2, on 64 bit, windows 7, and I have a problem with the import of the MXF op1a (IMX 30 PAL) files that I exported from first.

    MXF Import blocks especially first, but when he's not, it takes a long time to import (10-15 min).

    I tried editing ContributeQ but again, it hangs / takes a long time and I can see only a black screen.

    I installed a new copy of windows on this computer with everything clean, but it doesn't seem to work.

    Is there a software patch or way to go around for this problem?

    Whenever you have trouble with this, reduce the number of influences of others on your system.  In this case, delete TotalCode and see if it behaves better.  If it does not remove the device from BlackMagic and uninstall the drivers.  If one of these steps will improve performance, check with the third-party manufacturers.  There may be a setting or an update is necessary so that your system works correctly.
