82579V Windows 7 - Wired Network Has Random Intermittent Failures
Jul 1, 2011
I just built a new computer running Windows 7 with an Intel 82579V Gigabit on the motherboard. Since last night while playing an online game, I have occasionally noticed sudden network failures where I either time out of my game or severely lag for 10 seconds before the game catches up.
My other network hardware and setup remains unchanged during this build.I have never had issues with my internet connectivity from my ISP.
The problem is not consistent and I'm not sure how to repeat it. I was playing my online game for several hours and then suddenly started having problems every 5 minutes with disconnecting.I can watch the network utilization in the Windows Task manager drop suddenly and then spike back when I reconnect to the game. Similar visual seen on the Tomato software on my router.
So far I've grabbed the latest drivers for the network chip from my motherboard manufacturer's website and turned off Teredo. I also made sure no power saving features were enabled on the network chip in the device manager.

When I turned my computer on this morning, it had no internet access.
I haven't changed any settings - I think there was a Windows Update though.
Windows 8, Intel 82579V.
The DNS settings are correct, that is, unchanged and what we have always used.
I can access the network fine, browse shares, see the other machines etc. but the network icon in system tray says "No Internet access.".
I can ping the gateway.
All other computers on the network have Internet access.
The network cable works and provides internet access when plugged into a different computer.
I have tried disabling IPv6. I have tried disabling/enabling the network connection. I have restarted Windows multiple times. I have tried disabling Windows Firewall.
I am at a complete loss as to what to try next.
ipconfig /all dump follows:
Windows IP Configuration
Host Name . . . . . . . . . . . . : cydonia
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Hybrid
[Code]......

I manage a VPN 300 concentrator which has been happily working for several years without any problems. All users are part of the same group and authenticate to an RSA server. We recently moved from RSA authentication manager 6.1 to RSA authentication manager 7.1. Everthing continued working fine for several weeks, then at the beginning of this week we started getting users intermittently failing to connect to the VPN. I'm not sure if this problem relates to our new RSA server, but we have other network devices which authenticate to it with no problem so I guess the problem is with the VPN concentrator itself.
When users fail they just get a generic "Reason 427 connection terminated by peer" error message. The live event log shows "group = vpn, status = Not-in-service" when their connection fails. Other times they connect normally and no error messages are displayed. There seems to be no real pattern, sometimes your connection fails but if you keep trying you will eventually get in [however it can take many attempts over an hour or two before you succeed, or you may get in straight away with no problem].
I dont believe its a network problem, as I have run continuous pings to the concentrator and the RSA server whilst users are experiencing these problems and there are no drops.
The RSA servers authentication monitor always shows that the user has successfully authenticated, whether the users connection actually succeeds or not. I am tempted to just reboot the concentrator, but we have site-to-site VPN tunnels connected off it and I'm a little concerned that if it is faulty it may not come back up at all.

Wired PC randomly disconnects from network at random intervals each dayoday it has done so 3 times. The only way I have found to get it working again is to reset the router which can be inconvenient. When it disconnects all wireless devices continue to work and I have no issues like this with my wired consolesI switched to using a static IP address, since having an automatic one gave me the same results [i have since switched back to automatic]Be happy for any suggestions on how to sort this. I am using W7 OS and I'm using an Orange router. I don't know if its relevant, but when I go to reset my router I have noticed that the download light on my router is flashing like crazy when my PC has disconnected.

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

I should start by saying I am no novice when it comes to networks but this router has been nothing but a issue since day one.
*The Setup - 2 wired PCS, 2 Wired Macs, 1 Wireless Iphone, 1 Wireless Ipad.
WPA2 Only / AES key, Channel 6, G/N only, Hidden SSID.
*The Problem - 95% of the time the wireless and wired is running fine. However, Sometimes randomly webpages on the computer will stop loading... but heres the kicker... other internet connected programs like Ventrilo, or torrents, or games will still be working and running from the net like there is no problem. When this happens the internet browsers on the macs and PCs will say page cannot be displayed instantly. Happens to all computers at the same time. After about 10min the webpages will load again. I have 16mbs internet and while this is happening my games and voice chat programs do not go up in ping at all.
I have turned off QoS since that made the most sence... but other then that I have no been able to figure it out. I even turned off wireless while it was happening and it still didnt fix it. A sure fire way to fix it is to restart the router.
I am 100% stumped. Do I just have a bad out of the box router? it is only 2 weeks old.

I administer a wired SOHO network at a business I own, which is nothing more than a XP Pro machine which doubles as a file server. Typically, there are only 3 or 4 work stations in use at any given time, with 3 printers being shared. Backups are done after hours through portable USB. I have a home quality Netgear router behind a cable modem, and unfortunately need to use two 8-port unmanaged switches due to limited cabling between the workstations and the server. Said switches/cabling could prove to be the culprit, except that it used to work nicely.
A few months ago, while browsing the shared folders where the bulk of the approximately 180 Gigs worth of largely graphics files...(browsing from ANY of the terminals)...I began to be aware of random delays of up to 30 seconds or more. It seemed to be a sudden change, but has grown worse over time.
The files in question typically reside under several subdirectories, ie My Network Places/GID/Designs/Stan/Photoshop Files/TeeShirts... and browsing to the actual goodies progresses nicely until the VERY LAST directory, then WHAMMO.....XP flashlight goes back and forth, back and forth, back and forth.....you might wait half a minute before seeing the actual filenames in the window.
Its exasperating, and can randomly happen even if I'm the only person in the building, and the "server" seemingly has nothing else required of it.

I've been having an issue with all the printers and print servers on my network. They work great with my wife's computer which runs XP, but my computer which runs 7 won't print. Tried a Cat 6 cable on one and got some results.

I have frequent intermittent 105 errors DNS Server not found. I run a Laptop, Win7 home edition 64 bit, Telstra TEHS_0c280c 3G usb Modem, I live 600 metres from Repeater and have consistant full WiFi strength. I have had this error using both Google Chrome and Internet Explorer.
When this error locks me out of the net, it is very frustrating as I have to reboot the laptop and reset the WiFi modem several times before the problem comes good. Sometimes this can take up to a full day as I can get the Net back and then have the 105 error again, and other days I will not see it at all.
Remedies I have already tried to no avail :- CCleaner to both remove cookies and clean and repair registry probs. And Defragging.

Windows Messenger continually connects and disconnects. This behavior is permanent I only have problems with Messengers (all releases), web page access is correct. I check bandwith saturation and It's ok, I use less than 50% of each DSL. I configured the correct size of MTU for each DSL and the problem continues.Is there any way to set priority to this service? Is there any way to check if the "load balance mode" affect this kind of connections?

I have two computers on a wired network, for simplicity I'll call them computer "A" and computer "B".Computer "A" is running Windows Vista Home Premium SP2, and computer "B" is running Windows XP Home Edition SP3.I can no longer get folders from "B" (XP) to open on "A", I say no longer because I used to be able to get them to open.The folders from "B" appear on the wired network okay when viewed on "A" but when I try to open them I get the message as in the enclosed attachment.I have tried switching off the Firewalls on both computers but that has not worked.

My new computer has a problem with the on-board gigabit ethernet it keeps dropping network connection every few minutes. Nothing has had any effect. It has been such an annoying problem, I really was hoping to find a fix for this sooner as I know other people have had similar issues. Does anyone have any other ideas because I would like to use the only ethernet connection sometime in the near future. Having to run of an WPN11 netgear usb adapter at the moment.

Went and exchanged the cable modem for a different one.I've tried changing the network to private, but it keeps reverting back to public itself.

We run windows server foundation 2008 and have about 15 workstations. I had been running the network on 10 workstations prior to moving the server to our new location about a month ago. All was working well. We had run with the 15 workstations no problem in our new facility for several weeks. many of the computers are dropping the network connection now intermittently, with no predictable pattern. I can't seem to reproduce the conditions that cause the drops.

Running 5 PC's and a laptop on a wired/wireless network at home. One PC running Win XP Pro started dropping the network connection (so it appeared) during browsing. Have found the following:
1. MSN messenger runs fine, and doesn't drop out
2. AVG antivirus updates with no issues
3. Web Pages in Chrome and IE will load fine one minute, then cannot load or pause for 1-2 minutes while loading
4. Can ping web addresses/IP addresses from command prompt with no issue.
5. Have changed the network connection from Ethernet to Wireless, which makes no difference to the issue.
6. If I "repair" the connection, and the network refreshes the IP address, I can browse successfully, for about a minute, before the issue occurs again. "Repair connection" again and can browse again for a minute.
7. Checking connected devices to the Netgear router, shows the PC name sometimes, against the IP address, other times it shows the PC as "unknown" against the PC address (when this occurs, web browsing is lost)
8. All other PC's on the network are fine.

I have a Compaq with XP wired on a Network with a Belkin N600 Router.There are 5 computers on the Network, (4 wired, one wireless) and this is the only computer that I have problems with connectivity. It connects to the Belkin through 2 switches.Typically when I turn the system on it connects, downloads mail, etc. After a short period of time there is no connectivity to the network for printing nor the internet.I may get connectivity randomly again after a while, but you never know if or when you will get connectivity again for sure. I am using Explorer.I had loaded some Belkin software with no luck so I uninstalled it. The other computers have no special software for the router.

I've been having some issues with my network connectivity for a while now, and I haven't been able to figure out what the problem is. I run a wired connection to an Ethernet port in the wall of my university dorm. I have verified that it is not a global network issue or an ISP issue; this problem only happens on my PC.My network connection drops/disconnects randomly throughout the day. When I say disconnect/drop, I mean that all attempts to ping or access the internet fail. A few minutes pass before the Network and Sharing center task tray icon shows a warning sign saying that my computer could not connect to the internet.This is temporarily fixed by doing an ipconfig /release and ipconfig /renew, but I have to execute these two commands about 2-3 times a day on average.
There is no exact interval between the disconnects, nor does it happen when I am running particular programs. The disconnect happens regardless of what I am doing at the moment (gaming, browsing the internet, leaving the computer idle).A month back, I installed some Windows Updates and suddenly my internet connection was almost completely broken. I was experiencing the same issue, but much more frequently. My internet would die within 10 seconds of executing any download, but Windows wouldn't recognize that something was wrong. At first I thought the ZoneAlarm, Avast!, or the SafeConnect (as required by my university) services were causing trouble but uninstalling/disabling these services did not fix the problem.I also tried reverting to my default ethernet drivers, which did nothing. I uninstalled and reinstalled multiple versions of my drivers to no avail.However, the internet worked just fine in Safe Mode with Networking, so I cross-referenced the processes/services running in Safe Mode w/ Networking against my normal startup, guessing something else was at play.After some poking around, I discovered that disabling the Server and Browser services permanently fixed the issue of instant connection death. But the initial problem I described still remains;random, less frequent internet connection drops.

I have cable modem coming into the basement hooking up to Linksys Cable Modem (1 yr old). The cat6 line leaves the cable modem and goes approximately 60' through the wall to an Asus-NT66U wireless router on the main floor into the WAN port.I then have a cat6 line go back through that same 60' of wall coming off the LanPort1 of the Asus-NT66U router into a Cisco/Linksys SE2800 8 port gigabit switch (a year old as well).
The problem I am having is as follows. I have been getting intermittent "Unidentified Local Network" problems off an on which I have tried many of the fixes for, evidently unsuccessfully ranging from duplex speed, network ID etc. I had updated the firmware on the NT66U to the latest and am still having problems.
I never have problems with the wireless network which always has connectivity to the internet, however the local is the regular problem. So, to further compound things I have 3 Smart TV's hooked up to the Cisco SE2800 switch over cat6 as well. Those were all working recently until this most recent hiccup and now none of them are working regularly. They can sometimes "see" the wired network and my media server software, but it is intermittent, slow, and never works and often can't see at all.
The TV's are all set to static IP's over the wired network (192.168.1.114/.115/.116) they are the only static IP's out there.The cables are all good and have been repeatedly tested in a variety of ways. All the drivers and firmware are up to date.I think I have a problem with the router/switch communicating and passing through data,The switch does not need a crossover cable, does not seem to have a management menu, and not sure what else to do.

I have a Cisco 1242 AG wireless access point with the goal of having multiple SSIDs. I set up one network which broadcasts correctly but only sometimes can I connect to it.
And, even if I connect to the network, I cannot get a DHCP address for the client.Other devices connected (but not through this Access Point) to the associated VLAN 60 can get a DHCP address and connect just fine.Here is the configuration for the Cisco 1242 AG access point in question: [code]
Lastly, here is the information on VLAN 60 from the distribution switch. As mentioned, other devices connect to this VLAN and get IP addresses just fine.

We are facing issue related to STP.I am getting MAC FLAP error on Cisco 4510 switch. The effect on network is intermittent Pkt drops in the network. When I checked the specific Ip address I am getting the same with two different. [code] Vlan is created on CORE switch and assign priority 0 than CORE switch should be the Root. but instead Root port is becoming the port where server is connected. Server at last connected to CORE switch via HP switch via other Vlan to CORE switch and creating a loop as shown in Diag. [code] The Priority of Vlan 102 is changed and Root port has been changed due to that. The Bridge ID is the same as CORE switch.

At first it seemed to happen everyday at the same time, but now seems completely random (happening twice a day somedays). At some part during the day while the user is busy with this system it drops the network connection. The ONLY way to get it back is by restarting via the reset button. Shutdown or even logoff just hangs. Nothing regarding that card will work or respond, you can not even disable and re-enable. I can however get the wireless to work without restarting. I've done everything I could possible think of including format and re-installing Windows. Something new I've noticed is that the user always has MS Access (in runtime mode) running while network goes down and then you can not end that process.

I have a mix of devices that all access the internet via a Deutches Telkom Speedport W 723v my windows devices, HTC phone and even the iPad 2 never have a problem, but my Macbook Pro (Unibody Late 2008 model) and my iMac (Probably 2007 / 2008) keep having a problem with the network dropping out. To fix it I have to switch off Airport and switch it back on again and it re-connects straight away.The Mac OSX software albeit now rather dated on both devices (The Macbook is 10.5.8) is kept up to date using Software Update.The problem amy also now be affecting my APPLE TV2 it never had a problem before but now I cannot connect to iTunes on my Macbook using Home Sharing it just does not want to connect!!!I did try before going into the Speedport and changing channels from AUTO to channel 1 but that did not resolve it. I am going to do it again and try a different channel but logging onto the Speedport is an absolute pain, I can only login using my Macbook Pro when it is booted into Windows XP and on Ethernet as we had all sorts of problems setting it up and could only do it using IE not SAFARI and now the Speedport login only recognises 1 x PC for logging in, if you try a different device it throws a wobbly and locks up!

I have been having intermittent wireless trouble. This includes Ping spiking, Wireless network drop-outs (The network stop appearing on available network list) and packet loss. This is all completely random (though very common) and is frustrating to say the least. As far as I know, the problem is not nearly as bad on other devices in the house , so I suspect that my network card has become shoddy. I have tried updating,removing,and re-installing network drivers to no avail. I have also used cmd and I have pinged 192.168.1.254, which shows random ping spikes, and some packet loss as well.

My router keeps crashing like it is restarting. it turns off then all the lights are beginning to turn un again after some time it repeats again and again....Last thing they did was turning down the internet speed for our Network. It worked in some time but then it begun crashing again...Then they said it was the cable in the road that could not take all the data stream... And something about and Bit error?I just dont belive the cable in the road thing because our neighbour are running 10 M/bits without a single error anytime... I am not an expert but i've found out that we are running a Sagembox or something like that. The hardware version (if that is important) is: 3DK04-02 Everybody in the house is running Win7 SP.1. If you need any more information then i will try to find them.

I am having an issue with 3 xp pc's in my network loosing connectivity to the file server. There are 4 network drives mapped to a win 2k3 server, when the user logs in everything is fine, after a while the network drives become unreachable and gives the following error - An error accrued while reconnecting (drive letter) to \servershare Microsoft windows network: The local device is already in use The connection has not been restarted” This happens from any user on only 3 boxes. The rest of the network is fine. These 3 are networked via a switch, I swapped that out for another hoping that might fix it, but nothing.
The other odd thing is the same time that the network drives error out it seems that DNS stops resolving anything outside my network. I can still ping the router and other pcs on the LAN but DNS fails to resolve any names for IE, and nothing outside the LAN can be pinged, no Google, no 8.8.8.8. How ever restarting fixes the issue for a short while. There have been no network changes and all systems are fully up to date as far as patches go. I was thinking it's got to be a ether a DNS issue (the file server is also the Active Directory Domain controller) or something in to do with the router/fire wall we use (it's a Cisco ASA 5005).

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.
I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

I noticed a TON of random devices showing up in my Network within Windows 7. When I say a ton, I mean 739! I am not computer illiterate, but definitely not a pro. My router is WEP password protected, so I'm not sure on earth is going on here. I thought maybe I had a torrent program open that could be affecting this somehow, but I don't..

I have this laptop with a built-in Intel Centrino Advanced-N + Wimax 6250 adapter to connect to WiMAX.Right now I have a WiMAX connection at home with a simple gateway. So what I want to do right now is trying to connect to this network using my built-in adapter.I'm facing right now is that the driver of the adapter only searchs for a certain provider from the US (Clear). I'd like to subscribe to their service but I live in Argentina so that's not a valid option. So my question is if you know of a custom driver or some other way to search for my local wimax network.

We have a bunch of computers(70 aprox) connected to a domain. Since couple weeks ago very strange issues started occuring, internet and network access(path to network share is lost) would come up at random times and on different machines and would last for about 10-20 seconds it would re-connect again.All the computers are using private addresses.Most machines are windows 7, some are xp.Using Windows server 2003 as dc.Since the occurance is so random it's very hard to pin point the cause.

This is also happening on more ports ie 20-printer, 13-Cisco Wireless Access Point, 24 File Server etc., which I don't know what is going on. With my research, it said something about spanning protocol. Is this possible to disabled?
The other cisco switch where desktop are also connected doesn't have this error.
My firmware is 1.1.0.73
Boot Version 1.0.0.1
