Slow Connection

Hi, i have just recently started experiencing a slow adsl connection. For 5 years i have had no real problems except random diconnections, until recently.For the last week my connection has dropped from a 1500kb/s connection to roughly a 256k connection. All telstra have to say is it seems fine on their end, when clearly it is not on my end. I have swapped modems same problem, checked all settings on he modem, until now has worked all worked fine. Have a speed tested over and over, even ping is higher than usual, in its current state the connection speed is unusable as i am a gamer and latency is too high to enjoy gaming. Any help or ideas would be appreciated. I am using a netgear modem, on an adsl2, 200gb plan.

hi, I am unable to test the phone to hear for a crackle as i do not own one, i only have the modem connected to the line and that is it.I would say the modem is probably at least 2 years old now. And before you ask, cause i asked telstra the same question, it has not been slowed for any reason, not for over usage or un paid bills. I first thought this cause it is running at 256k, which is the slowed speed, but they said they did not slow it. I have spoken to them a few times now, and so far they said they would call me back after 8 hours, which didn't happen, and then they said they are still looking into it.In the past i have had drop out issues, which would occur like every 3 months or so, i would contact telstra and it would fix until it started again. The frustrating thing is every time i call, they always say, seems no problem here must be your end. And everytime they fix it without ever having to visit my premises.So again the connection is also dropping out and is slow, i did try another modem, and it suffered the same slow speeds.So here i am waiting again on telstra to do something.

  • Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

    I have racked my brain and done everything that I know to do for about two weeks now.  I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
    profiles.  It keeps telling me that the roaming profile could not be loaded because of a slow connection.  These are workstations that are connected directly to the switch that the DC is connected to.  I have tried multiple connections regarding
    the layout (DC into the router, router into the switch).  The router is a Cisco RV220W.  I have two VLANS, one for public and one for private domain.  The Private VLAN has DHCP turned off since I am providing it through the DC.  I currently
    have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
    The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port).  I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller.  The DC can see
    the internet fine and the workstations can connect to the shared folders on the server.  I can retrieve files by just using the computer name or FQDN.  The DC is also running DNS and DHCP.  The DNS has the _msdcs setup from when I installed
    the active directory role.  I have attempted to assign static IP addresses to the workstations:
    IPV4 Gateway:
    IPV4 DNS:
    I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
    The server is assigned:
    IPV4 Gateway:
    IPV4 DNS:
    The DNS entries have forwarders that forward to my ISP DNS servers for lookup
    I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
    I've lost my patience with this project and am sinking fast.  Can someone please offer some advice as to what I've done wrong?  I've created this exact scenario at work many times but, I've never done it with Windows Server 2012.  Is this
    possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV?  I am going to attempt to work on it some more tomorrow when I get over there.  I think there may be an issue with the SR-IOV not being enabled on the machine
    through the Dell Bios.  Would the SR-IOV really cause the workstations to report a slow connection?  When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct.  I don't
    have "ignore slow connections" or any of those GPO's set.  I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem.  Any help that someone can offer, I am more than willing
    to listen.  If you need more information, please ask.

    So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
    post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
    virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
    Im disappointed in MS right now.

  • Mavericks install incomplete. No Apple installers on HD. Will I be able to upgrade to Yosemite and will it fix all that didn't install with Mavericks upgrade? Very slow connection speeds 30 hrs to download Mavericks. Tried re-install; no help/

    Ever since upgrade to Mavericks I have been having problems which are too numerous to mention. I finally found a program from a UCBerkley professor called Pacifier which indicated 4000+ of 400,000+ files and folders did not install. I was unable to go further to try to fix everything because Pacifier can't find ANY Apple installers on my HD. It recommended I download the Mavericks installer without reinstalling to continue; however, after having done so (very slow connection; takes 30 hours to download) and although the installer appears in apps while downloading it disappears and NO Apple installer packages can be found on my hard drive. I tried to download Yosemite once and it indicated my system wasn't eligible for the upgrade. Its' download time was similar to Mavericks; 28+ hours.
    I am using a Macbook Pro mid-2012 version OS X 10.9.5 (13F34); Processor 2.5 GHz Intel Core i5; Memory  4 GB 1600 MHz DDR3; Graphics  Intel HD Graphics 4000 1024 MB.
    Regardless of how many files and apps I remove my memory is being eaten up to the point I can hardly do anything at all. There are no civil words for how frustrated I am. Someone please help me.

    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.

  • My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

    My 1st Generation time capsule won't connect to the internet thru a new motorola sb6121 - get continuously flashing yellow light. Using a router in between the modem and capsule yields good but slower connection to internet. Any thoughts?

    Thanks for your response
    Let me give the history - I started with an Apple Express being fed thru a D-Link  EBTR 2310 cable Router from an RCA DCM315 Modem (Pure). Comcast service all the way.
    Got the 1st generation TC in 2008 and merely replaced the Airport Express with the TC. Worked ok
    A year or two ago I did try removing the modem and feeding the TC directly from the modem. Resulted in the same condition I have now - Continuous flashing amber on the TC. So I put the router back in the chain.
    Some time later, at the recommendation of a Comcast rep, I replaced the router with (a Belkin F5D 5231) to see if speed and dropout problems would be improved. I thought it helped some at the time but now I am not so sure.
    Last week I decided to see if a new modem would help with download speeds. So I got another pure cable modem (Motorola SB 6121- high on the Comcast recommended list).
    Got up and running easily with Comcast help and with the modem connected directly to a computer.
    Next I put the TC in the link and again could not get past the TC continuing to flash amber. Although I did get connected to the internet with this configuration I lost connection two both of my printers - one connected by USB and the other wirelessly to the TC. Again everything works fine when I put the Belkin router back in the system.
    However with the router in there, the modem shows the downstream connection to be 10/100 ethernet speed. (Modem light changes color for indicating speeds.}
    I have gone thru all of the combinations of powering down/ up, but all stays the same.
    I can live with what I have but something still doesn’t seem right.
    Thanks again

  • Satellite U400 - Slow connection on Windows 7

    I use Satellite U400.

    > what kind of forum is this? no help for more then one 1 week , more then 10 days now ?
    What are you expecting? This is a user to user forum if someone would like to help you then he will post in your thread.
    In most cases such themes has been discussed a lot of time here maybe you should not wait only for someone but should use an advanced search option and could search and read in similar threads for possible solutions
    Regarding your issue:
    > i do have the latest updates and still nobody from you tried to help me to get a fix , why dont you guys belive it? when i said look at and write windows 7 wireless probblem or slow down my wireless, this is a KNOWN issue with windows 7 .
    Firsty you said that you are sure it's Win 7 issue
    >i have asked around everywhere and they all say it is NOT windows 7 issue it must be the manufacter driver issue .
    Now you are saying it;s notebook issue....
    So what is your possition now????
    How it could be a manufacturer issue if the speed is faster using WIn XP??? For me it make no sence...
    However, I googled a little bit an found this:
    Tweaking Windows 7 for Faster Online Connections
    You can also try to speed up the IE 8
    For that use the command: regsvr32 actxprxy.dll
    This should be typed in RUN
    Then reboot the notebook.

  • I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... The product distribution file could not be verified. It may be damaged or was not signed.

    Hi folks,
    I tried downloading the latest OS X Mountain Lion and [after a long time... I have a slow connection] I got an error message ... We could not complete your purchase The product distribution file could not be verified. It may be damaged or was not signed.
    Everytime I retry or continue the download I just keep getting the same error message!!!
    What can I do to get my product?

    The only thing that worked for me was to boot in safe mode.
    Power down.  Then press power button and hold 'shift' key until grey screen with progress bar appears... Once booted and logged in just open safari and browse to applestore. 
    No trouble at all once I did this.
    Reminder: create full backup before you upgrade OS
    Hope it helps.

  • Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting?

    Problem: slow connection. I have an iMac (2007) running on Mac OS X 10.6.8. I just had my internet speed increased from 1 to 3 Mbps but my connection slowed down considerably. Do I have to change any setting on the computer, and how?

    One possibility is that you may need to "Upgrade" your Cable /DSL Modem if you have an older unit.  ISP's that provide your Internet service in recent years have been switching over from DOCSIS 2.1 version Modems to DOCSIS 3.0 version Modems, which handle the new higher data streaming speeds the ISP's are offering.  I would suggest you call your ISP's Technical Support and inquire about this possibility.

  • How can I download a full installer to move to a computer with a slow connection.

    Due to slow connection speeds at home, I need to download the installers fro CC and premiere at work, then take the full installers home for
    installation on a different computer. The installer "stubs" we can download will not suffice.
    Understand, there are no alternatives. It's either this, or I have to use a different product altogether.
    Something I can either fully download, or buy on a CD or DVD.

  • Firefox much slower connecting to all web sites than Internet Explorer. Why?

    Over the last few weeks, Firefox has become much slower connecting to virtually all web sites that I frequent than does Internet Explorer. Nothing has changed on my computer other than occasional downloads of Firefox "improvements".

    A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

    I have slow connect speed when using the WRT160N. I have tried every thing, done dianogstics on connection, router, modem, thru three diffeant software, norton, windows, system machinics. when ising the router some days the speed is amost like using dial up
    I use XP, on both a laptop desk top, up to date drivers, both cna use wifi or direct connection by cat 5e, 3 m of ram, a wimax internet server,,,,, (company called Bridge Maxx)
    But when I stop using the router and connect directly to the modem no problem works fine,,,,, not sure what to do........ just need my wifi back,,,,so i cna work,

    Whats the Version number of your Router, If you have having version2 router, then there is an knows issue with Version2 Router. Downgrading to Build 8 is generally accepted to correct these issues, however Linksys have indicated to several people they do not have the build 8 firmware to give to end users.
    This is ONLY for WRT160N V2 routers. This firmware will not work on WRT160N V1.
    You can find it at
    Follow the dowload and firmware downgrade instructions on that page.
    Once you upgrade the firmware of your router, you need to Reset your Router and Re-Configure all the settings on it back again. Once you do the settings on your router i think this should solve your problem. 

  • Snow Leopard Server's slow connection when connected to AirPort Exteme

    I've been experiencing slow connections ever since I hooked up my Mac Pro server directly(via ethernet) to my AirPort Extreme. Previously, the Mac Pro is connected to a switch, the AE is connected to this switch as well. Everything's fine until we decided to connect the Mac Pro server to the AE directly. Now we are having slow connection and checking Network Utility, it shows that en0 is receiving errors when previously there is none. I have connected a client computer on the same cable and it receives no errors. It's just the server that's receiving these errors. To clarify thing up my server's network configuration is as follows:
    IP address:
    Search domain:
    I have configured my DNS server to use's IP) as the Forwarder IP address so that my server and other client computers can still connect to the internet.
    Checking the client computers connected on the same network, they are experiencing slow connections to the server as well.
    There must be something that I need to set on this thing to make things work, any help would be much appreciated.
    Thanks and regards,

    I forgot to check my cables. Apparently they have used crossed-cable for the previous Mac Pro to switch connection. After connecting the server to our AirPort Extreme things got a little sticky, using a straight cable did the trick.

    Hi Earsdale,
    All the three servers are using the same configuration, so, I'm afraid it's not possible to give you a simple answer. You will need more troubleshooting.
    I would recommend you to start by checking the differences between the servers because one of those differences is certainly causing the failure.
    Also, it would be helpful to get traffic captures on the TenGig interface of the ACE to compare the behavior of the connection when going to the different servers, as well as the differences when being load-balanced vs accessing the server directly.
    If you need help with this troubleshooting, you can always open a TAC service request

  • Slow connection between two Macs in LAN

    Why does it take so long to connect one Mac to another Mac's public folder on LAN?
    Mac mini 2.4 GHz (the latest model with 4 GB RAM) is connected to LAN with 100 Mbps LAN cable;
    MacBook Pro 17" 2.33 GHz (2 GB RAM) is connected to LAN with AirPort 802.11 (G) via Linksys router WRT54GC.
    Both computers are in the same room, Linksys WiFi router is 6-7 meters away, excellent signal strength. It takes about 50-55 seconds while MacBook Pro connects to the Mac mini. Why so long??? Do they use 2kbps connection speed? I thought with these network speeds (54Mbps for WiFi, 100Mbps for LAN) it should be almost instantenious…
    Both Macs run 10.6.4.

    I'm having the very same problem, but only when connecting to one of the 3 Macs on my network. it eventually connects, but only after about 55 seconds. Connecting to the other 2 Macs is almost instant, so it leads me to believe that there is something wrong in the setup of the "problematic" Mac. This slow connection happens using either "Back to My Mac" or just trying to connect via Finder. Any ideas would be very welcome!

  • Help : very slow connection speed with AEBS and iMac

    I connect to the internet using my newly purchased AEBS. I have a MacBook and an 24" iMac ( purchased in Nov 2007). My iMac showed very slow connecting speed of <1 MB/s download; with my MacBook placed just 1 foot from my iMac, the MacBook showed an amazing download speed of 20MB/s. If i connect the iMac to the AEBS using ethernet cable, it can get a very high speed.
    So, where is the problem??
    I am new to wireless, please help. I use iMac more than my MacBook at home.
    Actually, i did not touch the any of the advance setting of the AEBS.

    You know, I am experiencing the same problem. My wife's PC and iPhone are blazing fast, but my MacBook is accessing the internet at about dial-up speeds. Very frustrating and I haven't yet found the culprit.
