Internet latency Internet connection / Intermittent

Hello

This is the first time using a forum to debug one of my computers.  I am ready to provide all the necessary information, but if you need something that special, you may need to tell me step by step what you want.  I'll give you more information as soon as I get home.

In any case, here's my problem: I got a new computer that once to the top and runing worked beautifully in my rental house.  About 1-2 months after we moved in the street (literally 2 houses down) and once I have configured my computer problems are beginning to be obvious.  Latency is horrible when you connect to the internet, my CPU running at 50-90% usage (there is no indication in the task manager that uses the CPU) wermgr.exe revolved constantly until I disabled it (when he was running, he never showed any USGA CPU), my connection with the default values of the router to 10 bits/s, when I force him to 100mps duplex full connectivity fails or the latency increases.

The desktop configuration is the following: 2 computers--> SMC router--> cable modem

1 computer is my wife (a non vista PC) which connects very well with no problems and gets speeds of transfers of 500 members (as is expected of Comcast cable).

What I've done so now trying to solve this problem: Vista will completely to dated, Ad aware of analyses (found nothing), analysis (found nothing), updated antivirus my ethernet card drivers, power manager updated drivers up-to-date, stop system of windows error reporting, tried new cables ethernet, reset the router, Manager of tasks of montiored for actiivity file unusual (nothing to report) and tried Windows Vista error setting suggestions.

I'll give you more information, but it is to get people thinking about this problem.  My computer is an AMD Phenom II x 4 940 Porcessor 3.01 Ghz, 8 GB of ram, NVIDIA Geforce GTX 280, nForce card Ethernet 10/100/1000 and Barricade SMC 7004VBR router.

Currtently online game is impossible and normal surfing of the internet strainingly latent.

Hope someone has some ideas for what to do.  I think then try CCleaner or try a factory reset.

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

Disable the IP helpdesk:

1 hold the Windows key and type R, type "services.msc" (without the quotes) and press enter
2. scroll down to the IP assistance service, right-click on it and select Properties
3. in the drop-down list box that says "Automatic" or "Manual", set it to disabled and then click 'apply '.
4. then click on "Stop" to stop the service from running in the current session
5. click on OK to exit the dialog box

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.

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:
322756 (http://support.microsoft.com/kb/322756/ ) how to back up and restore the registry in Windows

Windows Vista cannot obtain an IP address from certain routers or some non-Microsoft DHCP servers
To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:
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.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ {GUID}
This registry path, click the (GUID) subkey that corresponds to the card network that is connected to the network.
On the Edit menu, point to new, and then click DWORD (32-bit) value.
In the new area #1, type DhcpConnEnableBcastFlagToggle and press ENTER.
Right-click DhcpConnEnableBcastFlagToggle, then click on modify.
In the value data box, type 1 and then click OK.
Close the registry editor.
By setting this registry key to 1, Windows Vista's 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.

The only program that I'm aware of that currently relies on IPv6 is the new Windows meeting space. The first 2 changes will cause this program is not to work - but all of your normal (IPv4) connections will leave unaffected. If it causes problems that you can't overcome, simply go back to the original settings.

To clear the DNS cache:
Click Start, type cmd in the search box, and then click cmd in the list programs.
If you are prompted for an administrator password or for confirmation, type your password, or click on continue.
Once at the command prompt, type ipconfig/flushdns

  • Laptops give up the Internet connection intermittently

    I have a portable satellite, and my wife has a Tecra laptop. We connect through a PC to the internet via WIFI.

    Two notebooks remove the connection to the internet intermittently - to connect in the first place, we need to click on a few favorites in internet explore - only then either connects.

    I also connected through a network of friends that is configured in the same way and the same thing happens. It has a portable older tosh which connects perfectly and does not drop the line.

    We compared the settings and all seem to be the same, so something else isn't quite right.

    I'm running XP (SP2), built in the LAN card (which is fine) and connect via a netgear access point, which is about 2 feet away.

    I'd appreciate any help in what he makes us all crazy!

    Hi Hunter

    I also use a wireless connection at home. Two of my books (P20 Satellite and Tecra M1) are connected to the Belkin wireless router. Setup was simple and without any problems and I had no problem at all.

    Can you please tell me what you use right now (point of access Netgear or desktopPC) for wireless connection? Use you the client or Windows to configure wireless network settings?

  • Satellite L300 - no Internet connectivity - intermittent

    Tonight

    I have a Toshiba Satellite laptop ancient - about four or five years. I'd give the model number, but unfortunately it has rubbed off the label underneath - is possible to find this out (I think it's a L300 - or something).

    I let the laptop all the time - leave the parameters energy saver it hit standby mode when the lid is closed.

    Sometimes (often) when I open the lid and the springs of the computer in the life, the connection is at Local level only rather than Local and Internet. A reboot solves this problem, but a reboot takes about five minutes, which can be a pain if I want to use the Internet for half a minute.

    Come to use the laptop now and it wouldn't connect - or rather, wouldn't get all web pages. This time the connection was showing however as "Local and Internet". I don't think it's the browser - use us Firefox or Chrome. In addition, the computer will automatically connect to Skype and it is only in a State of the connection.

    I just uninstalled the wireless driver - do not click the box that says 'delete the driver software for this driver' however. Of course, this requires a reboot that solves the problem anyway, so I don't know if that solves the overall problem.

    If anyone knows of any diagnosis that I should run while the machine is not plug in, but please let me know.

    This same problem who spent a year or two he's has and then just stopped that happening / it is now started again - current for about a week.

    Any ideas anyone?

    It is under Windows Vista Home premium and use AVG as a virus checker - if that makes a difference. I have a new Toshiba netbook and that works perfectly on the same wireless network. I have not tried this portable annoying on a different network.

    Thanks in advance.

    To be honest I didn t understand your problem.
    To work well WLAN driver must be installed and card wireless network enabled to verify please once more if the correct driver WLAN is installed. You can do it in Device Manager.

    Use the FN + F8 key combination and remember the wireless network adapter is correctly enabled. After doing so scan the area and control available to the local wireless networks and try to connect to your WLAN at home.

    Have you tested with battery only or the same problem occurs with food running too?

    Sorry, that did not help.

    I understand your frustration. It is very aggravating to lose your connection, especially when you watch videos or download files.

    You can try to change the channel on your router.

  • iMac intermittent Internet connection... a little

    Good evening to all!

    I have an iMac mid-2011 running on OS X 10.10.5. A few weeks ago it started giving me *. Most of the time, it works very well. However, from time to time (it can vary from once in a weekend several times a day), he abandoned the Internet connection... a little. It is quite complicated to explain, and English is not my native language so patient with me. Randomly, some Web sites and right areas will become inaccessible. Reloading Web pages does not get me anywhere. Does that change the error message in my browser that will come to me. I can also access most video games require an online connection while my iMac is upward. I can quite strangely, still receive and send emails and use applications such as Skype or uTorrent. Some sites Web will always also. Most of the time, YouTube is completely functional. Is the same for the Google search function, although I can not load search results when I click on them. Facebook tends to load with an extremely messed up display. I say 'more' and ' tend to "because it happened a few times that even these sites Web would not load. Applications like Skype and Mail have never failed me up to this point. Homepage of Skype app comes down with the drops, however.

    I use mostly Chrome, but the problem is also present on Safari. I've not installed on one of these two browsers of extensions. The problem is not limited to my user. Other iMacs on the network experiment not these drops. Restarted my iMac seems to fix it temporarily. I tried to use other DNS. The issue is extremely intermittent and the 'drops' length varies from a few seconds to an hour. Here are the screenshots of the various errors that Chrome gives me (there is no reason, reload and another one pops up). I know they are in French, but it's the best I can do. I'm really desperate for help because I'm taking courses online soon.

    uTorrent is your problem.  Relying on software illicet means that may have installed something that hurts your connection to the network.  Sorry, but you really need to remove all software obtained torrent.  Get software only directly from the developers and the Mac App Store.  MacUpdate is good also, but never get Mackeeper.

  • Intermittent: No Internet connection

    On my HP TouchSmart 600-1055 running WIN7 64 bit family professional, I have intermittent problems. Sometimes the icon that looks like a bar graph in the lower right corner contains an asterisk to inform me that even if I have a wireless connection to my network, I don't have access to the Internet. The only way I can get access is to restart the computer.

    Is there a command that I could run for re - initialize connectivity without having to reboot? Closing the connection and then reconnect in do not solve the problem. Troubleshooting can't find any problem. Open the network sharing Center was not so far assistance. There may be an option that I have to reset?

    I really need a command that deletes this diagram to bars and resarts connection from scratch. I turned my router Cisco Linksys switch to no effect. I haven't touched my Bell modem 2701HG - G high-speed, because my connection is stable. This problem does not occur on any of my other computers on my network.

    I also ran the HP Support Assistant, but everything seems OK, once I have an Internet connection. Any suggestion would be appreciated.

    First of all, thanks a lot for taking the time to answer. I've delayed until I have studied it more in response to your suggestions.

    You suggested a weak wireless signal. This computer is about 4 feet apart, so the signal strength is excellent.

    Your comment that some parameters of intellectual property made a mistake was probably the cause of my problem. First of all, I have disabled my wireless and opted for a wired connection. Nothing like a direct cable connection to solve all my problems. Have a computer without problem a few days calmed me enough to try again. I redefined my wireless Internet connection. This product icon barchart containing an asterisk. Then I ran the Ethernet troubleshooting, wireless and other network cards. This allowed me to activate my wireless connection. Finally, I created a restore point. Creating a restore point has become my favorite after all command change s/w.

    So far so good. Maybe the wireless knows that if she does not behave I'll replace it with a wire.

    Your comments and your similar problems were exactly what I needed to hear. It would be nice if HP could allow some restore settings by default for each h/w device. MS has done this for IE.

    Once again thanks for your help to solve this problem.

  • How you would solve intermittent Internet connectivity?

    How you would solve intermittent Internet connectivity?

    Hello Chit mickolo,

    Thanks for posting. Intermittent connectivity can occur for several reasons. First to get a better idea of your installation. Do you use the dial-up or high speed internet? You have wireless or wired connectivity, and whether this happens at a time. You have multiple computers on your network? When this happens does occur with all or a computer? What troubleshooting steps have you made so far if necessary to solve this problem?

    Once again thanks for posting and I can't wait to hear back on your part.

  • Intermittent internet connection.

    Hi, I have a Linksys WRT54G Router and have been meet with intermittent internet connection on a daily basis. I tried several things to solve without result. Any suggestion would be appreciated. Thank you.

    I think that you need to update the firmware on your router.

    Go to the Web site template linksysbycisco.com/downloads...insert of your router in search tab... select the correct version of your router... Download the firmware file... save this file on the desktop

    The firmware was updated.
    Follow these steps to upgrade the firmware of the device: -.
    Open a page in Internet Explorer browser on a computer hard wired to the router... In the address bar type - 192.168.1.1... Leave name empty username & password admin lowercase usage...

    Click the 'Administration' tab - then click on the 'Upgrade Firmware' under the tab-here, click on 'Browse' and navigate the .bin firmware file and click on "Upgrade"...

    Wait a few seconds until it shows that "the update is successful," after the upgrade of the firmware, click on "Reboot" and you will be returned to the same page OR it will say 'cannot display the Page.

    Now reset your router:

    Press and hold the button of reset for 30 seconds... Release the reset button... Unplug the power cable from your router, wait 30 seconds and reconnect the power cable... Now re - configure your router...

  • Problem with internet connection 64-bit Windows Vista, unexplained intermittent failure.

    original title: PROBLEM CONNECTING WINDOWS VISTA 64 BIT INTERNET - UNEXPLAINED INTERMITTENT OUTAGES

    On HP a6542p PC with factory installed Windows Vista (64-bit), Vista operating system program does not take account of Internet broadband, which, in reality, a good connection.  for the first 2 years of operation, the PC internet connection worked well, but a year ago, he started this OFF intermittent / WE internet problem.  SOMETIMES, I can manage to temporarily restore the internet after running randomly across the machine diagnostic & installation programs available to the home screen, OR SOMETIMES also after running REGEDIT in the start (search) bar and watching the TCP/IP settings (do not change them, just watch), but the internet connection drops again after the machine is idle for a few minutes.  I get very tired of the exercise Dog & Pony to run through the different random procedures & hoping that something will work.  I tried the fix from Microsoft using a flashdrive D/L from the Windows site to my XP machine and tried a few manual corrections proposed on various websites, but nothing seems to work.  I have no HP manufacturer disk to reload the Vista operating system.  The connection is good, the cable is good, but Vista gives me contradictory information about the diagnosis, such as ERROR 815, and he tells me also a cable is disconnected (not true, the cable is plugged & good & works very well when the Vista connection is restored), while another diagnostic message indicates the internet connection is good, at the same time other messages say is not.   What can I do to fix this problem in Vista?  Personal e-mail is: * address email is removed from the privacy * -I will check that URL of Web site for the possible answer.    Thanks in advance.

    Imrand - Thanks for the tip, I tried it & it didn't work.  However, I found an update of the HP driver for the network card Realtek in my machine, & after d/l this new driver, the problem seems to be fixed.  The Web connection is still good after several cycles of closing & reboot.  I'm not sure, because with this HP Vista PC, I can never be sure of anything, but I think the problem might be due to the rotating system off the NETWORK adapter in sleep mode, & so not put on when waking up.  Diagnostics messages confused and contradictory pages of different screen Windows were of NO use, it looks like the internet connection was good (which it was), while the other would be at the same time say there is no connection due to the disconnection of the cable, while the other at the same time say that the DNS server broadband couldn't recognize my internet query.  Total BS of Vista, which has compounded the problem than he was.  I only am not surprised Microsoft abandoned the Vista operating system so fast, so many other users of Vista have similar internet connection problems.  The user friendly and very stable XP operating system I have on an old PC of Insignia is my favorite.  Microsoft had to quit with it, IMO.

    Thanks for your help, Cimarron

  • intermittent internet connection of HP pavilion x 2

    Hello

    I bought a x 2 Pavilion 11.6 "2 in 1 15 days ago and I am constantly thrown out of my internet to explore link (says I have no internet connection) despite the internet access the bars showing the complete connection. My ISP is Virgin.  My old PC that runs windows 7 and new HP daughter divided x 2 13 '' who is running windows 8.1 that connect well to the router at my house and my new links pavillion x 2 fine for the interntet via wifi at home and work without any problem.

    I tried to re-creation of my router several times and this solved the problem for about a minute at best.  We bought two laptops through Curry but they refuse to come to the House to make a configuration despite offering to pay for the service and they say that there is no fault woth the PC because it works in some places.

    Sometimes to investigate the question of nework arrives with a (999) network connectivity problem, sometimes he said to re - configure the router/modem - but as stated earlier, this only solves the problem for a very short time as HP performs automatice reapirs - (reset the "IntelR wireless-N 7260" adapter) which lasts about a minute.

    After having spent £429 on this beautiful piece of equipment please can someone help me to get my emails and the internet?

    Following my message of origin above;

    2 in 1 is a HP Pavilion x 2 11-hoo3sa 11.6 "F4T44EA #ABU

    I've updated the media tek 802.11 wireless LAN adaper pilot.  He advised to remove the previous Chuck but I did not do what was not sure where to locate it - is this possible now?  I had already updated the network wireless driver intel 7260 (who had made no difference) there are two other di network = River updates, but they do not seem to be related to my problem, so I did not download them.  I did have the chance to try the new driver but I have to go elsewhere to access the internet to communicate with you all.  If I assign a fixed address as suggested before that would mean that it does not connect when I'm anywhere else?

    I'm a pretty confident user of PC - the technical stuff moved from my comfort zone, but will try to follow the instructions.

    Help, please

    I had the same problem of intermittent WIFI connectivity, but only on an old router on holiday in Spain.  Everything works very well at home in the United Kingdom.  My flag is fully patched for drivers and windows 8.1.  I just couldn't connect to the router for more than one minute at best.

    the difficulty is to force the WIFI card to use the old WIFI Protocol:

    Device Manager-> network adapters-> Realtek RTL8188EE 801.11b/g/n-> properties-> advanced-> Wireless WiFi adapter is IEEE 802. 11 b

    probably because that HP haven written their system software successfully to detect old routers that supported the old protocols... like millions of people around the world use every day...

  • Windows 7 of intermittent wired lan/internet connection.

    In a Word, my Windows 7 Ultimate (64-bit) PC intermittently drops his internet connection. Why?

    Reminder: My PC is connected to my DSL modem/router that is directly connected to the telephone line. I also have wireless connectivity enabled in the router for a laptop to the wireless network.

    Every few hours or more, using my PC, I find I can't access the internet and the pages will not load. Finally, Windows7 will update the network icon in the taskbar to display the symbol of an exclamation mark on the network icon. Opening of the network and sharing Center will show the red cross between the 'multiple networks' and 'Internet '.

    I'm running VirtualBox of Sun on this machine and creates a network connection for itself. This doesn't seem to affect the intermittent dropping (i.e. drops intermittent occur if the connection of VirtualBox is used or not) and indeed, I installed on the two other machines (Windows XP and the other Vista Home Premium (32 bit)) of VirtualBox and these work without any problem.

    When the connection does not drop, I can't access internet pages, or I can access the router at http://192.168.1.1/ web administration page, so I guess I lost all local LAN access too.

    It certainly isn't the router (or the Internet itself) as my laptop, using the wireless connection (and running Vista Home Premium) continue to be able to access the internet (and the pages of the router web admin) very well.

    Whenever this happens, I can immediately restore all the internet and local network access by opening the network map page, disable the "connect to the Local network' and then the reactivation. Give it a few seconds and all is well again. I guess that's because, under the MISTLETOE, it actually makes a "ipconfig/release" then "ipconfig / renew".

    The allocation of IP for Windows 7 computer is the same before and after the "drop". I have a DHCP server on the router issuing IP addresses, but my Windows 7 computer uses a static address (192.168.1.2).  I also tried with a dynamic IP (served to the ADSL router) and there is no difference.

    There is also no specific measure in the event logs various system, other than what relates to the abandonment plug which is a "customer DNS event" and it is generated once the connection dropped and is an event specifying DNS information that could not be found for any Web site I can I try to access, just after the connection is interrupted.

    The NIC chipset is Realtek PCIe GBE Family Controller and I have confirmed that it is the correct chipset for the motherboard (Asus M4A77TD PRO), and in fact, Windows Update installed a driver for this updated January 12, 2009. Details of the update is an update of the Realtek software since December 2009. Either way, I was still having the same intermittent problems before this update. He seems to have done no difference at all.

    Anyone know why this is happening and how to fix it?  I have looked for answers to this and seen a few other people (even on the MSDN/Technet forums) affected by the same or almost the same problem, but with no clear resolution. Suggestions of disabling IPv6 on the LAN adapter and ensure there is no power 'dormant' management the network adapter have been tried but do not cure the problem. It doesn't seem to be a particular sequence of events likely to occur either. I got to go twice in 20 minutes when just randomly on the web without any other traffic and I also had it go once then not again go for 2 or 3 hours with the same type of use.

    Can anyone tell me why this is happening and how to make it stop?

  • Intermittent slow internet connection

    I've been running windows 7 (64 bit professional) for several months now and at first, everything was great. However in the last few weeks (maybe even as long as 2 months) I've known internet connection problems. All started with my computer randomly, dropping its internet connection and eventually processed in high latency problems (something of the order of 8000, yes thousand, ms). I first thought that maybe my NIC went out on me, so I replaced it. That worked very well, for about 24 hours, and then the problem was back.

    I know it is a question of windows because I tried the exchange of material and nothing worked, and I have a number of other computers in my household with Vista and Windows 7 which have no connection problems either. Sometimes my NIC uninstalling and reinstalling it will make me some time where everything is working correctly. Im running and motherboard intel (DG33FB) with a dual core processor, which once again (and I can only emphasise this point) was working perfectly before this show, despite this Board is "fully supported" by windows 7. I searched the net and tried a few things - research and the deactivation of Hello (I didn't), forcing my 100 Mbit/s/s Full Duplex adapter, install drivers Vista 64 bit in mode of compatibillity for resoove the common communications controller PCI question with some Intel motherboards, etc. I am at the end of the roll and would appreciate greatly any help. Again, this is not a router/ISP issue, as all my other computers work fine, even those with windows 7 - the problem is with 1 machine.

    Thank you

  • Intermittent problem with IP addresses and internet connections dropped

    Once a day or so my PC (Win7) will not be able to access the internet. Connection just drops. I use DHCP for IP addresses.

    As far as I can see in the Event Viewer I get these types of errors "the address lease IP 192.168.1.64 for the network card with network 0x406186808C4C address was rejected by the 192.168.0.1 DHCP server (the DHCP server sent a DHCPNACK message)."

    My local network is simply: PC-online router (Cisco E1200)-online internet (modem Siemens SpeedStream 4100 DSL)

    "When this happens, we run ' ipconfig - release 'then' ipconfig - renew." This usually fixes the problem. Sometimes, this does not solve the problem, and we need also the modem power cycle. In a few minutes find us the internet connection. It's nice to have a manual correction, but we want to solve this problem to happen... as is the engine of our family crazy...

    The address LAN IP of the modem is set to 192.168.0.1

    The address LAN IP of the router is set to 192.168.2.1

    When things are running OK, I usually see it in the ' ipconfig-all the ' results: = 192.168.2.147 IPv4 address (Preferred) [but the IP numbers change slightly] my understanding is that see "Present" in the result is a good thing (but I don't know why...).

    Any thoughts on what is happening? and how to permanently solve this problem?

    I'm also confused on IPv4 and IPv6. Should I be concerned with any information of IPv6 in the ipconfig-all the results?

    Thanks for the help

    Talked with the ISP (ATT). Zig - zag, you were on the problem. I had both modem and router set to DHCP mode... so I had some conflicts. The solution was to define the "bridge mode" dsl modem and configure the router to "PPPoE mode. Everything works now. Thanks for your help.
