Internet very slow on Windows 7

A few months ago, I bought a new computer with Vista and experienced terrible internet speeds.  We have dsl and the other computers in the House all the fast internet in xp, so I was sure it was a problem with vista, as described here: http://social.answers.microsoft.com/Forums/en-US/vistanetworking/thread/74f41557-4dd7-44f5-ba39-4b6009520aef

I was happy to install 7 because I didn't know it would solve my slow internet problems, but... it didn't.  My internet is still very slow, and the machines running xp always move at the speed of light.  This happens in IE and Firefox, and internet is always slow, even using a different wireless adapter.  Any suggestions?

Method 1. Reset TCP/IP:

To reset the stack TCP/IP go to this article and either click on "Fix it for me" or follow the instructions to fix it yourself: http://support.microsoft.com/kb/299357

Method 2. Disable the DHCP Broadcast Flag:
Link: http://support.microsoft.com/default.aspx/kb/928233
Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base:
http://support.Microsoft.com/kb/322756 (how to back up and restore the registry in Windows)
Windows 7 can not get an IP address from certain routers or some non-Microsoft DHCP servers
To resolve this issue, disable the DHCP BROADCAST flag in Windows 7. To do this, follow these steps:
1. Click Start, type regedit in the search box, and then click regedit in the list programs.
If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}
3. in this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.
4. on the Edit menu, point to new, and then click DWORD (32-bit) value.
5. in the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.
6 right-click DhcpConnEnableBcastFlagToggle, then click on modify.
7. in the value data box, type 1 and then click OK.
8. close the registry editor.
By setting this registry key to 1, Windows 7 trying to get an IP address using the BROADCAST flag in DHCP Discover packets. If that fails, he will try to obtain an IP address without using the BROADCAST flag in DHCP Discover packets.
 
Method 3. Disable IPv6:
Try to uninstall IPv6 on all interfaces, the removal of virtual cards of IPv6 and reset the TCP/IP stack. To remove the IPv6, go to the properties for each network adapter, and deselect the check box next to the Protocol "Internet Protocol version 6 (TCP/IPv6), which will turn off, or select it and click on uninstall, which withdraw power off the computer.» Then go into Device Manager and remove any 4to6 adapters, adapters miniport WUN or tunnel adapters.
NOTE: You should do this for each network connection.

It will be useful.

    I apologize is not getting back to you earlier.

    When you download and install games and other you don't normally need to keep what you have downloaded in the downloads folder. Some downloads are wide to remove could free up some disk space! You need to do on a regular basis to keep on top of the problem...

    The content of your video in total 414 GB file. You might look at some of them again? If this is not the case, delete those that you no longer need.

    You have a lot of icons on the desktop. Take a look at these and remove those that you never use.

    When you did above select Start, all programs, accessories, System Tools, cleaning disk to emptying your trash, delete temporary Internet files and other selected options. I recommend also you click Other Options, System Restore and delete all but the last system restore point. Run Disk Defragmenter.

  • Internet very slow on Windows 7, I tried a lot of bugs with no luck

    I have Windows 7 Professional 64-bit. I used it without a problem for several months. But lately I had a very slow internet connection, no matter what program I use to. The same computer dual-boots with Windows XP: XP connects to Windows 7 to 0.3 Mbps and 8 Mbps.

    Security software: Avast and Comodo (use every two months with no problems).

    System Restore has been disabled by mistake, there is no restore points for trying.

    I tried EVERYTHING to fix this! I tried:
    -disabling auto tuning (this greatly improved navigation on the web, before pages would take ages to load, but the download speeds are still slow)
    -Disable IPv6
    -Disable Windows Firewall
    -disable the Windows Defender real-time protection
    Re-setup of ethernet card
    -Re-installation of network card
    -uninstall the Windows updates (those I was actually able to uninstall)
    -boot by using the system configuration to start without starting programs or non-Microsoft services
    -reset the TCP/IP stack
    -safe mode with networking
    -disabled the DHCP broadcast flag
    -change the heuristics of Windows scaling (since he says this overrided other parameters) and the provider settings control congestion

  • Internet very slow with Windows 7.

    Here's my problem. Since I installed Windows 7 Pro x 64 my internet acted weird. There are 3 other computers on the network that is running Windows XP Pro 32-bit and a running Vista Home Premium 32 bit. Every time someone else is downloading something or watch a movie online my internet slows to void / 3Mbit normal speeds dial-up is the speed. He does only on this computer, when I download something none of the others slow down at all. It does this with 7 also, it does not do this with XP or Vista. I have searched all over the internet and have found nothing useful. Everything I've met has not worked a little. I've reinstalled 7 a few times and even tried all versions of the card ethernet driver I could find and nothing helps.

    Hello Remi R,.

    Thanks for posting in the Microsoft Answers forum! Try to start your Windows 7 computer to SafeMode w / Networking to see if the slow speeds still occur. There may be third-party software that is causing your problem. If you please, after back and let me know the results.

  • Some games run very slow on Windows 8, as...

    Some games run very slow on Windows 8 as (chicken Invasion "v1, v2, v3" in red alert 2, Age of Empire 2)
    but on Windows 7 on the same Machine perform perfectly, I tried to install DirectX,.
    and tried to install the latest Version of the Driver VGA for Windows8 and tried to change VGA (Nvidia, AMD, Intel)
    but the games (not all games just a few) still running slow...? !!!
    Help, please...

    Wrong, wrong, wrong.

    This is entirely based on compatibility to a level beyond what is offered in the standard "Windows compatibility" section.  In addition to this, everything you said had absolutely nothing to do with the question.  This has nothing to do with starting or whatever it is in the same direction.

    What is happening is that something is interfering with the normal functioning of the game because of changes in the kernel of the operating system because it has been updated / rewritten since the inception of Windows XP.

    @SOVIETTION
    The most likely solution for you has nothing to do with the videobuffer here is how fix you it:

    Find the Red Alert installation directory and find the file * md.ini.
    In revenge for Red Alert 2/Yuri, it will be 'RA2MD. INI"(feel free to make a backup of the file before proceeding)
    Open it with your favorite text editor (Notepad for most people)
    Scroll down until you find the section [Video]
    Just below you will add this line-
    VideoBackBuffer = no
    Save the file in the same place and load the game.

    Enjoy!

    The VideoBackBuffer = none works perfectly, but in my case I also had to set the compatibility mode to Windows XP SP2.

    Bravo for you!

  • Equium A60 very slow with Windows XP SP 2

    This Toshiba unit very boots very slow, it takes forever to get started it got a software firewall installed but it is not correct that it really takes ages to boot up a laptop like this.

    Hello

    I had the similar problem with my Satellite P10. After installation of SP2, the startup procedure takes much longer. Check please the processes that start to run and disable some of them if you n t need them.

    Have you installed SP2 or it is also to the recovery image?

    In my opinion, it is not specific for certain just usual laptop models. My second unit (without SP2) starts a lot faster.

  • Very slow initial Windows Update

    Hello

    I just did a fresh install of Windows 7 Ultimate 32 - bit with Service Pack 1.  The initial check of updates has managed to update updates Microsoft, but the initial check for updates of the race since (oh I dunno) 15 or 20 minutes...

    Is this just normal planned waiting for initial windows update time?

    Something has hurt very very badly with Windows Update.

    I agree.   I did a new install of Win7 SP1 yesterday and left Win Update running from one day to the next day - it was always check the updates when I got up this morning.   I thought some of the customizations I made before you start the update might have messed up things so I decided to reinstall this morning.

    First I tried the installation option by using the option to use the latest version on the web - I canceled that after that he spent an hour "collection of information" is then returned to the installation from the CD.   Once I had a fresh install of Win7, I immediately started the update.   It was now 'check updates' for about 3 hours.

    One thing I noticed, is that the history of the update shows that the update agent (7.6.7600.320) was installed during the installation.  It seems to me that the Windows team needs to get some people working on back out this version of the update agent so that Windows can actually exists to update himself.

  • Why Thunderbird runs very slow on Windows 7 CAUSE: McAfee

    Installed Thunderbird worm 31.6.0 on my desktop Windows 7 Home Premium, SP1, 32-bit, 4G ram, Intel i5 processor clocked at 2.66 GHz,
    a few months ago and he ran very well in the beginning.
    Now that I've used for some time it slowed considerably.
    All Thunderbird functions slow clicking to select a group of messages, even deleting just one single message, opening a message, etc.
    It has compact records on several occasions, and I did not have a large number of stored messages (maybe the total of all files, including waste, spam, sent, etc. is about 500).
    I use McAfee Anit-Virus, which ignores analysis attachments to emails.

    There were reports of slow performance with Thunderbird on Win7?
    Maybe my problem is caused by McAfee?
    Ideas, suggestions are welcome,
    Thank you

  • Equium L40 very slow and Windows Defender found a Trojan horse

    I was wondering if you could help me with a situation.

    Turned my laptop on and Windows Defender found a Trojan, so I chose all clear. Then it arrived 5 minutes later and I pressed on delete everything again.

    Afterwards my internet is incredibly slow and often freezing.
    Opening files and folders often locked up but I could still click on the red X if it took 30 seconds to close after that I clicked on the X.

    I get now random pop ups not even on the internet.

    Do you have any suggestions?

    Thank you.

    Hi Kieran

    Have you tried different antivirus software?
    I would recommend this. I use a software called Antivir freeware antivirus and it is nice.
    It of free and you can download it from various internet sites.

    In addition, you could use an Ad-aware to kill this Trojan horse. It of also for free and maybe it could be useful too.
    Google just to download it for free.

    If you won't be able to remove the virus from your system by using programs like Antivir, antivirus Norton antivirus, etc. and then use your Toshiba Recovery CD.

    I think this should help.

    Good bye

  • Cannot download or is very slow since Windows updates!

    My computer was working fine. Could he download without any problem. Windows has a few important updates, so I installed them. All updates were for MS Office, except IE8. Since then, I can't download anything with Filezilla. It timesout. I can get the files downloaded through CoreLite, but it runs at a rate of 3 kb/s (compared with 80 + kb/s) before. Download on 4shared is too 3 kb/s. download speed was cut in half or even slower!

    I reversed the update iE8, but that did not help. Ive been Googling for a month now, trying to find a solution, but nothing seems to work. Does anyone else have this problem? If so, how to solve it? Any help would be greatly appreciated!

    Here's my info and what I've tried so far:
    Windows Vista
    Excluded for the Windows Firewall programs include FileZilla and Core.
    Tried system restore, but a date before the update was not showing.
    I have a router, but this computer is connected directly to the modem.
    Cleared cache... and restarted ten-gazillion times.
    Router factory reset.
    Turned off modem for 10 seconds and rebooted.
    Tried the FTPES setting, but it would not connect to the server.
    Disabled firewall and tried.
    Cut of the AVG resident shield and tried.

    I run a home based business that depends on me to be able to download files. Thank you very much in advance for the help with this!

    Use the systemrestore to go back before installing updates. Now install every single update and look at what update causes the problem. "A programmer is just a tool that converts the caffeine in code" Deputy CLIP - http://www.winvistaside.de/

  • Lack of hardware drivers, the Windows Live programs do not work & Microsoft Outlook 2010 is very slow in Windows XP computer.

    Victorinox original title: my PC is in need of serious help!

    I will have questions both of I don't know where to start?

    #1) I think Miss me the hardware drivers, what can I do to check and make sure I have the latest driver updates for my hardware?

    (#2) I have programs such as MS messenger, some programs MS Live Essentials that I can't use, fix, uninstall or reinstall.

    (#3) MS Outlook 2010 is super slow, freezes, don't play well with other programs and finally stops after a while.

    (#4) instead of "restart" my PC stops completely down and don't come back or restart when I said to "restart".

    (#5) according to ARO over 3900 registry errors, which I am sure that is why I...

    (A) I have several MS security updates will not be installed, (all the directions say to change records and do all sorts of things, I don't think I'm qualified for this.

    (B) PC is generally slow and lazy and even if it is a work computer, it's me from being productive, and I don't have the time.  It starts slowly, and I don't know how to "truly" remove startup programs, etc.

    It is a working PC, should be a whole day to re - install Windows on top the other things would have to do to make it fully functional again, drive mapping, loading the programs clients, plug-ins, etc. on top of losing this day there all the work, we would have to pay the computer scientist for that all day. Our guys 'IT' knows all the fancy words for all the 'IT' stuff he does, but he has the patience to follow through and fix things until they are really fixed, it starts simply, then vibrates on a list of things to do after his departure... and it is overpriced, even if he was as good as he thinks he's.  But I have no say in this.  I'm not the admin PC I don't think, but I can run & install programs on the PC.  We use TrendMicro, which I'm not thrilled since I just cleaned my PC my 3rd year Trojan horse was not detected by T.M. but was detected by other things, such as MSE and MalwareBytes.  Where should I start, how to get it all cleaned up, & what should I do to keep it?
