Intermittent Connection/sporadic Packet Loss
Aug 7, 2008
Need if there are settings in Vista SP1 that would affect sporadic severe packet loss or intermittent connection? I am trying to troubleshoot my internet connection. So far, Comcast has put in new cable lines/splitters in my house, new termination at the pole and a new modem. Problem still persists. What I have done on my end before Comcast got involved:
1. Update chipset drivers
2. Tried new NIC
3. Upgrade/downgrade firmware on Router
4. Removed Router
5. Removed software firewalls and AV
6. Complete reinstall of Vista with slipstreamed SP1

I am connected to the Internet through and SMC Barricade G router. The computer is hardwired Ethernet to the router. A second computer in my office is also connected via Ethernet to the router. The connection is lost for several minutes, and then it restores itself automatically. The Vista Event Viewer shows several events which may have initiated the loss of communication.
1. Event ID 27; Intel(R) PRO/1000 PM Network Connection Link has been disconnected.
2. Event ID 2505; The server could not bind to the transport DeviceNetBT_Tcpip_{737A72A7-5D80-4E6B-B2B4-1F599399F2E5} because another computer on the network has the same name. The server could not start.
3. Event ID 4321; The name "NEWTECHFX530:20" could not be registered on the interface with IP address 0.0.0.0. The computer with the IP address 192.168.2.103 did not allow the name to be claimed by this computer.
4. Event ID 1003;Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 0019D16D7512. The following error occurred: The operation was canceled by the user.. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

My Network and sharing Center is an action movie. I have two days with that windows maximixed, I turn on the computer and everything is great for no more than 2 minutes, then the action begin, the red X appears between the Network and Internet Icons, I lose conectivity from all, it came back after 15 secs average, then after one minute 6 tops is down again. Sometimes appears a warning triangle sign between my pc and the network icon then I get "limited conectivity" and it fixes by itself after 15 to 20 secs. Is like that all day.

Can connect to Outlook server over VPN with Vista home Premium (32 bit), but connection drops out after a few minutes. Requires reboot. Access to server files stays connected indefinitely.

I have sound turned off and there is an odd intermittent and sporadic noise that comes from the speakers. It happens when there are no applications open and is not in response to any action. It sounds like a single drop falling into a bucket of water. My computer is only 2 months old and this noise has happened the entire time, even after reinstalling OS (due to crash).

I have an intermittent slowing issue. Sometimes on system startup, the computer will be running very slowly, as though there is a huge drain on system resources- taking 10 seconds plus to open IE, for example- but when I open the task manager and take a look, I'm never using more than 10% CPU (its usually more like 4%) and physical memory is usually around 30-50% used.
This problem can persist through a reboot (where the system will appear to hang on the "Shutting down..." screen for up to 10 minutes), but through a restart or two I can usually get it to go away.

I am facing a strange problem with my HP Dv6705 laptop running on Vista Professional. I have a Wi-fi router configured for internet access. Now, the internet connectivity is intermittent i.e. I am connected to the internet for about 5 seconds before it gets disconnected. I get the connectivity again after a few seconds before it gets disconnected.
Now, I started using the uTorrent application after which I got prolonged connectivity. From the past few days, whenever I need uninterrupted internet I need to turn on the uTorrent application. It is quite strange that I am the only one who needs to do this while the others in my house (who have similar laptops) do not face any problem. Is there any way to detect what exactly is happening and how I can resolve this uTorrent workaround?

I have a four machine network. Two laptops running Windows XP Pro SP2. One laptop running Vista Home Basic. One laptop running Visa Home Premium. Both the Vista machines are up-to-date using Windows update. The machine which runs Vista Home Pr mium is on almost all the time - sleeping at night and being woken up In the morning. The other threelog in for a few hours daily.
The modem/router is a brand new Netgear DG834GT, firmware version 1.02.19. The Vista machines each have Atheros AR5007EG wireless adapters, both running with the very latest driver dated 5 Sep 2009. The network name is "Netgear". All machines are configured to obtain IP addresses from the router, which has the correct address range settings (i.e. excluding its own address)..............

Since I have installed Vista Home Premium I have had an intermittent "Blue Screen" problem with the following Stop Message:
BCCode: 4e
BCP1 0000009A
BCP2 0007DF69
BCP3 0000006
BCP4 00000002
Files that help describe the problem:
F:WindowsMinidumpMini020407-01.dmp
F:UsersRogerAppDataLocalTempWER-84968-0.sysdata.xml
F:UsersRogerAppDataLocalTempWER918C.tmp.version.txt
BCP2 has different code every time this happens but other codes remain the same. To get out of the situation I select "Last Known Good Configuration" at Start Up and then I can go for an extended period before the problem re-occurs. In original received a message saying there was a problem with the graphics driver but this driver came with Vista.( Nvidia FX5200) also at one stage Microsoft told me that there were some issues regarding the driver but nothing has come of it.
Microsoft's online support here in Australia is very poor at the moment,taking a week or more to respond and then they keep on repeating themselves now they have admitted that due to the release of Vista they are receiving alot of emails and suggested I phone them instead but I can never get through. So there we are. Does anyone have any idea what these codes mean and what the files mean? Everything works fine in "Safe Mode" so there must be a an issue with hardware/ software?

I have a new ASUS Laptop with Vista Home SP1 (with a sweet 512M dedicated video card) connecting wirelessly via a Linksys WRT54G router. The firmware on the router is current and Linksys assures me that there are no known issues with Vista and internet connectivity. I have a MacBookPro that connects w/o issue (wireless) and three XP machines that connect just fine (wireless and direct connect) so I know my network is solid. The laptop always connects on reboot, but conks out without warning after 45 minutes or up to three hours. Even when it seems like the laptop is offline, I can often ping a website through the command prompt. The "diagnose and repair" option just tells me eveything is fine. Windows Firewall has default settings. Already disabled IPv6.

For all of you G7 owners who continue to struggle with random freezing:
As others have so eloquently noted there is a strong consenus that this is a hardware issue potentially related to multiple factors including radio interferance, battery malfunction / contact issues, usb power, etc.
Here is a list of things to try, any of which may (or may not) solve the problem:
1) unplug the usb transmitter from the adapter and plug it back in. This did the trick for me about 50% of the time. Sometime toggling the DPI buttons (the + and - buttons on the mouse) up and down also helps.
2) if the freeze gets so bad that the cursor wouldn't move try shutting down the PC, unplugging the cord to the power supply, toggling the power supply switch to discharge the motherboard capacitors, then turn on the PC and reboot.
3) clean the battery contacts. Remove the battery and use one side of a Q-tip soaked in isopropanol and clean the contacts on the battery and inside the mouse (the 3 prongs sticking out of the end of the battery slot). Make sure to use the dry end of the Q-tip to remove all of the isopropanol before sticking the battery back into the mouse.
4) if the transmitter is near a wireless router or other transmitter (bluetooth radio, modem, etc.) place it as far away from these devices as possible.

When i upgraded to Vista x64 it felt like i lost preformance and when i tested 3Dmark06 again i end up with more than 1000p less 12300p. I have tried both unclocked and overclocked and Vista keeps giving less scores in benchmarks than XP.
Anyone got a clue why?

My wife's computer is running Windows Vista. The system works fine for almost all purposes. It accesses the Internet successfully through a wireless network card to our home WiFi router. The WiFi connection is fine with a high signal strength. It's connecting to an old DLink 802.11b router using WEP encryption, which is all the router supports. Periodically, on average every few days, she will lose HTTP connectivity. This happens in both IE7 and Firefox 3.08. She can still send and receive email and still use a web browser via HTTPS, but she cannot connect to ordinary web pages on port 80. The problem normally persists until she reboots, at which time connectivity is restored. Two other computers on my home network (one Linux, one XP) are unaffected. They work fine through the same wireless network while my wife's Vista computer is not connecting...............

I have just purchased a new computer from Dell and assumed I would have some problems learning a new OS, but I did not anticipate the loss of a good applet like Microsoft Fax. I counted on this small program for occasional direct communication with other facilities fax machine. It was quick and easy.
I have a second older Dell computer which I invested with hardware updates in preparation for upgrading to Vista as well. The lack of fax capability in Vista precludes my upgading as I need one machine that can function in a more complete manner. I don't pretend to understand the rationale behind this lack in Vista but I sorely miss the function. Others have teased me about my early adoption of Vista and now I am definitely embarrassed. I sincerely hope Microsoft will reconsider this situation and perhaps at least offer a download correction to improve the functionality of this Vista suite......

I am having a problem with losing disc space. I recently caught and presumably deleted a Trojan, Zlob-X.a. My computer was fine for about 48 hours after the removal. Now every time I connect to the internet I lose GB of hard disc space (about 1 GB every 5-10 minutes). The loss or continues for several minutes after I disconnect, as if something has downloaded and is expanding in the background. No spyware removal tool or antivirus has detected anything.

I have Vista Home Premium. I have two Hauppauge 1600s and a Nvidia 8600GTS. I have been receiving all my local digital OTA channels just fine since getting this machine 6 months ago, and now suddenly the local CBS affiliate, channel 4.1, is gone. Just gone. Dead. I get nothing but the No TV Signal blue screen. When I go to settings and check the digital signal strength, it is totally dead. The dreaded red bar. All other channels come in at six green bars, just like 4.1 did until this past monday.
I have tried re-setting up the guide, I have tried recording one digital channel while trying to view 4.1 to check if it's just tuner 1. Both times I get the blue screen. I then took the cable out of one of the tuner cards and ran it directly into my TV and the signal comes in almost perfectly. Why is the signal suddenly gone on just one channel?

loss of Internet Connection in Vista; completely loosing my Home Network; random
Internet Lags and Drops; and it seemed the only solution was to Reboot my
Computer to get an Active Internet connection. I applied many of the
Hotfixes; and used all of the Suggestions but nothing seemed to work. The
one thing that did seem to make sense though was the Tech advice here and
their that would say it was a Hardware Issue with Routers, etc.
So this is what I did; I went out and Bought the D-Link DIR-655 which is
Certified to work with Vista. It arrived last week; hooked it up and since
then I have not had 1 Internet Drop; or have I lost my Home Network. Now my
Computer can stay on; go to sleep; and when it wakes I have an immediate
Internet Connection. On the Upside the speeds are much faster as well
instead of your basic 100mbps; im getting 300mbps. So it was well worth the
Upgrade to me. It actually made sense that to take advantage of some of the
new options with Vista Networking that you would need a New Certified Vista
Router. Im actually very glad I did it; no more headaches and reboots. Hope
this helps anyone who was going thru the same Issues I was.
Oh and by the way just so you know here is what I have going on with my
Network: My New PC; 2 Mac Books; 1 older PC; 1 Xbox; 1 PS3; and 1 Wii; and
the VOIP.
I also used to use the Hawking Booster on my Network to help with VOIP lag
and arranging packets; but I also elminate that now because this new Router
arranges the packets and no Lag on the VOIP.

Having surveyed numerous similar posts I am at a loss as to how to resolve this issue, hence posting my specifics...all help greatly appreciated.
I am running Vista Home premium, IE8, Firefox 3.5.3, AVG free and Zonealarm. On starting the PC there is no problem connecting to the internet through either browser or updating email (Windows Mail).
Problem...
Loss of internet connection via IE and/or Firefox whilst Mail can still send/receive. I have tried clearing the cache etc but the only thing that works is re-booting the laptop (Dell XPS 1330).
I mainly browse with IE but downloaded Firefox in case IE was the problem. One or the other will lose connection first then the other will follow.

While being satisfied by the cool effects and new interface of Windows Vista Codename Longhorn, many of us testers are what you would call "gamers." The lot of us would like to know if gaming on the default Vista Supplemental drivers would mean loss of graphics quality compared to using up to date drivers on a XP OS. For example, I installed Vista and then installed my trusty game, Battlefield 2. I tried using the new nvidia Vista drivers but the game kept crashing when I start it up. So I reinstalled the Vista Supplemental drivers and it happened to work. Quite interesting. I am able to run the game on default vista drivers and not the nvidia vista drivers. Coming to conclusion, would using the vista drivers result in loss of quality and graphics compared to using up to date drivers on a XP system? Or you can also rephrase it; Would gaming be better on the Vista Beta or XP? Does anyone know if SLI works on Vista?

We use a financial application that stores financial data for clients in a database file (mdb). When we run the application in Vista as-is (i.e. without enabling "Run as Administrator"), we see [and can retrieve] any saved case data. However, if we enable the "Run as Administrator" option and launch the app we no longer see that saved data in the application. If we disable the "Run as Administrator" option again we can once again see that saved data in the app. Any new cases saved with the app open with "Run as Administrator" enabled do not seem to disappear like the ones saved with that option enabled, regardless of whether the option is enabled or not. Does this particular option perform something like a "rollback" when enabled, causing sort of an undo action to happen to the application, or could this be some kind of security issue that "blocks" or "hides" the data?

I am having the worst problems connecting using a cable connection, which I need because as I am in Europe at the moment, many sites or private homes are not equipped with wireless. Now, when I connect with cable, everything seems to be working fine, the Toshiba connectivity doctor tells me I am connected, the diagnose program assures me that the problem has been resolved etc. etc. and yet whenever I try to connect (IE, Mozilla, Google, I have tried them all), I get an error screen. I have tried everything I could think of, checking my settings etc. Nothing works.
Let me emphasize that:
1) wireless connection works fine
2) it is a problem with my computer, not the host, since I have encountered
the same problem everywhere (libraries with password protected access,
private homes without password protected access etc.).

I have a strange problem. I have AOL broadband and I'd like to connect to the internet without using the infamous bloated AOL software. I know how to do that using Vistas' "set up connection or network" wizard and I can successfully log in using by username and password. The problem is the connection is very poor when I use this method. The speed tests show the correct speed and downloads are full speed but pages seemingly randomly do not load (for long stretches of several minutes). For example my home page does not load ("page cannot load" error), google does not load, some pages load but not fully with many errors.
This isnt a browser issue (I tried firefox, IE, chrome), this isn't a modem/router issue (I have a laptop that works fine with a permanently logged in router), it's not an AOL issue I can still log in fine with AOL software and then browse fine with firefox, it's not a hardware issue, and it's not a firewall issue (it's off). Therefore it must be an issue with the way windows connects to my modem when using the built in PPPoE broadband connection. I really have no idea what could be wrong. Maybe one of you do?

With Vista, I can get internet for my new Dell XPS laptop over the wireless connection without doing anything other than selecting the connection. No user name or password is needed. But to plug in directly into my cable modem, it does not work. Seems to require user name and password. But I use Verizon and a Motorola SB5101 modem and while it is broadband, I did not think it is pppoe. I don't even know of any user name or password for my account. Am I wrong, is all broadband pppoe? My internet connection works just fine without asking for pppoe login info when I use my desktop with Windows XP. So, it seems to Vista specific problem.

I'm using Vista Ultimate x64, and a few days ago I started having troubles connecting to the internet. I have tried using both cabled and wireless connections, and both ends up with the same problem. I do get IP-adress, DNS and gateway from my D-link DI-624+ router, and when i try to ping a hostname on the internet ie. vistax64.com it resolves the hostname to a IP-adress. In "Network and Sharing Center" there is a red cross between my gateway and the internet-icon. I have no trouble connecting to other computers with other versions of Windows on my local network. The connection is also set to a "Private Connection".

I have been having ridiculous amount of trouble setting up my Linksys DMA2200 extender and I am a tech. I finally set it up and I also creating some instructions on how to set up the extender properly. Hope this helps you in getting your extender to work and save you the time it took me. All the updates listed are required and I do not have Service Pack 1 installed. I am using the advanced firewall ON in Windows and not using LiveCare and running AVG and no problems. View my site to see the list of items required for configuration to get the Windows Media Center to work properly with the extender. Also, the other link below has all the codec's that the DMA Extender to work. If your extender drops connections constantly set your NIC card to not go into Power Save mode. If it continues then reset the extender (Button in Back) Note: Need to hold it for 30 seconds. Then, turn on the extender and reset to Factory. Repeat setup process. If extender continues to lose connection after turning off again then contact Linksys or Seller for replacement.

It appears that I do have a very serious connection problem, which has popped up suddenly out of nowhere with no sensible explanation.
When I go to "Connect to a Network" I see that my connection has only one of five bars, with the connection status listed as "Low." When I go to "Control Panel>Network and Sharing," and "View Status" I see that the "IPv6 Connectivity" is listed as "Limited."
I removed the "Microsoft 6to4 adapter" previously because it had a yellow exclamation point listed next to it in my Device Manager after having read on the Internet that it could be deleted without any side effects if a person can't get it working, which was what I did. I now see that the "IPv6 Connectivity" is listed as "Limited" when I go to Control PanelNetwork and Sharing Center, and am wondering if this is due to my having removed the 6to4 adapter even though the system said it wasn't functioning properly. But I didn't have this slow connection problem until just the last couple of days, and I deleted the 6to4 adapter over a week ago.

I have a Dell Inspiron 1720 with Windows Vista
I'm trying to connect to some unsecure wireless networks at a friend's house for the first time and am only able to connect with local access.
I try diagnose and repair and it says that there are no issues. Three other computers are connecting to the internet just fine.
They signal is good, and there is supposedly data being sent and received but no programs will connect to the internet.
This issue has never happened before. I regularly run a registry cleaner and tried restoring to a backup from a couple days ago and that didn't help.
