Ethernet Connection Lost (and Found?)

[Xello]

Hi guys, are you all experiencing the same errors i am in the Event log? "Name resolution for the name (random website here) timed out after none of the configured DNS servers responded."

One person in the 50 page thread mentioned this, and the reply was that this was because his ISP does not support ipv6 so to disable it. I've done this, and the problem persists.

Motherboard/NIC: Gigabyte X58 Extreme / Realtek 'RTL8168D/8111D'

Wired or Wireless: Wired

CPU Architecture: x64

Upgrade or Clean Install: clean

Driver details: default windows 7 driver

Problem description: intermittent losing connection, like the rest of you. Not losing total connection, torrents continue to upload, but losing IRC / windows live messenger / browser connection.

Am i the only one that has a dead network adapter when i install the realtek driver upgrade that Windows Update gives you? When i install that i lose ALL connectivity, it just bricks the whole thing.

I have a new MESH preinstalled with windows 7. .

Solutions or Suggestions: It gets better if its nudged. But very irritating nonetheless

Motherboard/NIC: Gigabyte P55M UD2/Realtek RTL8168D/8111D
Wired or Wireless: Wired
CPU Architecture: x64 Core i5
Upgrade or Clean Install: Clean
Driver details: Realtek RTL8168D/8111D Family GBE NIC (NDIS 6.20)
Problem description: After Windows Update did it's thing, network connection was lost.
Solutions or Suggestions: Driver Rollback fixed it.

Functional driver in use now is version 7.002.1125.2008 - this is the one that came with Windows 7. No problems whatsoever with this - I've 'hidden' the Windows Update version to stop it being installed again.

I had also done a clean install on my mother's P4 based machine a couple of days earlier with the same result - also a Realtek NIC. I found that uninstalling and then 'scanning for changes' fixed the issue - sort of - this needed doing every re-boot. Of course, after I had done that once, there was no option to then 'Roll-back', as the 'newly installed' NIC only ever used the newer (malfunctioning) driver.

Her symptoms were that the comp could now see 2 networks, both unidentified, and neither with internet access. I could access the router's pages but get no further.

I used a spare wireless dongle to get her on-line, but even that had problems as I had to install it using compatibility mode (vista driver) and then it wouldn't work if the network was set to 'Home', only when I set the network to 'Public' did the connection remain stable. (the wired connection wouldn't remain stable, whether Home or Public was used.)

HTH

• Motherboard: Asus P5K SE/EPU
• NIC: Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller, built into the motherboard
• NIC Driver: v.2.4.7.29, 10/13/09, installed by Windows Update. I don't see any newer ones around.
• Wired or Wireless: Wired
• Router: Linksys WRT54G2
• CPU Architecture: Core 2 Duo E8500
• Upgrade or Clean Install: Clean
• Problem description: Every time I start a backup to my Windows Home Server from this computer in Windows 7, the connection drops almost immediately. I disable and re-enable the adapter, and it comes back. Other network usage is fine. This adapter works fine in Windows XP on the same setup. Switching to my other ethernet adapter, an add-in card identified as "ADMtek AN983-based ethernet adapter", works fine.
• Solutions or Suggestions: For me at least I think this is a driver problem.

Same here, it's not completely fixed but it's not as bad as the newer ones.

Xello, where in the event log are you seeing that error? I'm having the same symptoms as you are where open connections continue to function but new connections cannot be created until reboot.

Updating to that Windows Update Realtek driver did not brick my NIC. All drivers seem to have the same functionality for me.

But in the event that it is a DNS resolution issue maybe this has more to do with Windows 7 and less to do with the network drivers?

I'm having the same symptoms as you are where open connections continue to function but new connections cannot be created until reboot.

Same problem here with an nForce adapter, except rebooting or re-enabling the adapter solves nothing. I've tried numerous drivers with no luck. I've also disabled IPv6, side scaling, autotuning. I'm beginning to think this is a Windows 7 problem. This is what I've found in Event Viewer: "Name resolution for the name _ldap._tcp.dc._msdcs.seini.digitalcable.ro timed out after none of the configured DNS servers responded." where seini.digitalcable.ro is my DNS suffix.
"Name resolution for the name images.google.ro timed out after none of the configured DNS servers responded."
If someone has a solution for my problem, please post it. Thank you!

Xello, where in the event log are you seeing that error?

Computer Management > System Tools > Event Viewer > Windows Logs > System

I'm thinking that this could be rather another result of the problem and not something that will help us locate the source of the problem, it could just be a generic message telling us that our connection to a server was timed out. It's -why- I am timing out that i need to know

I'm seeing the DNS error in my event viewer, too. Here's one: Name resolution for the name photos-g.ak.fbcdn.net timed out after none of the configured DNS servers responded. They happen for different sites, randomly. I can go for hours without a drop, then two might happen close together. My local network seems OK but I can't get out to the net, and "no internet access" is shown in the network center. I wait about 60 seconds and connection returns by itself. never had these problems on Vista. not total loses of internet connectivity. This definitely seems a Win7 issue.

Tried OpenDNS servers on my router and in Windows, now going back to ISP DNS servers.

• Solutions or Suggestions: This is my first post in these forums, so i hope it ends up being a useful 1 . After pretty much trying EVERYTHING from multiple different forums, I ran into one person suggesting a solution that worked for him. It involved "DISABLING", RECEIVE SIDE SCALING in the advanced tab under driver settings. This seemed to work for me...so far. It used to disconnect within 2-3 minutes at full 1.5 MB/s. Now I'm over 3 hours at full 1.5 MB/s, while streaming to my media center PC, and while engaged in random web browsing with no disconnects or interruptions of any kind. (This is also with the newest drivers from nVidia). Good luck, hope it works for you guys,

If you're posting, definitely check your Event Viewer (go to Start, Search, type in Event Viewer and hit enter.. then go under Windows Logs, System) for events like this:

Name resolution for the name teredo.ipv6.microsoft.com timed out after none of the configured DNS servers responded.

The error code is 1014.

For me, they are occurring exactly when my internet connection goes plort, and seem to be bringing on the failure rather than simply being a side effect of it. Receive Side Scaling doesn't seem to have any effect... I thought it did at first, but no.

Thanks for the suggestion, i have set it and will report back. Looking at this page though it seems like a nice thing to have on:

What is "receive side scaling" means ? when you wanna make a team on 2003 windows server? - Yahoo! Answers

For me, they are occurring exactly when my internet connection goes plort

Me too, but the more i think about it the more it seems to me this is simply a message telling us that our connection to a server was timed out. This is easy to achieve, wait until your connection is crapping out then in command line type in "ping -t www.yahoo.com" and you will get plenty of time outs.

I do think whatever is wrong may be getting reported in the Event Viewer somewhere though, i've just never used it to trouble shoot a networking problem so i'm not sure where to look

 

[kourgath]

i've been encountering the same issue i believe. to clarify.
internet connection stable with no activity.
very light useage does not drop connection.
anything cpu intensive (ie. games, large file transfers, streaming, watching blue-ray) drops the connection.

Problem description: connection drops under cpu load
Solutions or Suggestions: the only solution i've had work reliably is to connect both ethernet lines and bridge them, disableing settings did not work, rolling back to stock ethernet driver did not work

 

[Xello]

Well the Side Receiving thing did not fix the issue with me either.

I also just realized that i had been connecting through my LAN port 2, not 1, so i've switched back to 1 to see if it does anything.

Can you explain how to do this please?

 

[kensiko]

Bridge them? Great idea, I now have 2 Ethernet adapters, so if the problem occurs again, I will try that.

It's simple, you go in the Network cards view, you select 2 cards, you right click and choose "Bridge connection"

Yeah but what is involved in using both ports for one connection? What's this adapter thingy?

As it stands my window looks like this:

It's still connecting, but will it cause any other issues?

 

[kensiko]

Yes, you will need 2 connections, 2 cables.

I don't know if there will be other issues, I think you won't get the IP you would have with only one connection.

Hi all,

Same issue for me on Windows 7 Home Premium Family (32 bits)

• Motherboard type : Asus P5Q3
• Wired or Wireless (or both) : Wired
• CPU Architecture (x86 or x64) : Intel Core Quad Q9550
• Upgrade or Clean install : Clean install (it's a totally new computer!)
• Driver details : Windows drivers, updated via Windows Update => Realtek RTL8168C
• Problem description (LAN? Internet? Frequency?): Losing connection with the router ; paquets lost when I ping it. Internet connection almost impossible.
• Solutions or Suggestions: What I've already tried => drivers changed, reboot router, cable changed, chipset drivers updated, ipv6 deactivated... I also tried to boot with Ubuntu 8 live CD : I noticed no internet/lan connection issue.

Thanks all for your help!!

 

[Xello]

Tried removing the router and plugging my modem directly into pc today, still had the problem so it's not the router.

Eventually i will perform a completely new install on another hard disk and find out if the problem persists on that.
