Let me first say this is an upgrade install from RC to RTM - so i know that might be the problem. However, i noticed one odd thing about my problem - existing network connections to the net seem to remain intact. Meaning, if i try to browse a web page when this problem starts up, i cant. But my remote desktop connect to my server, which was already connected before the problem starts, remains working fine. I'm using an asus p5k se motherboard with the onboard nic. I have the latest drivers (also tried rolling back to a older one). Never had this problem on Beta1 or RC1.It seems to be completely random as to when this will happen. But usually only seems to last 10-15 minutes before it occurs. The only way i have found to correct it is to disable and re-enable the network connection. I know it's not an issue with the router because another pc (also runnign win7 RTM) does not experience this issue.I can however connect to the router's web interface. I can also ping the 2nd pc - although it doesn't show up under 'network'.i can not ping/tracert to anything on the net. If i wait a few minutes, the problem seems to clear up on its own, but then repears again later at some random time.I do not see any errors recorded in the event log. Althought the other day i was seeing the following entries: The description for Event ID 194 from source AtcL001 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: \Device\NDMP22 Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller The specified resource type cannot be found in the image file

I have the exact same issue. I have a P5K (Not SE). also i do remember that 7000 and 7100 did not have the atheros L1 drives by default - i had to use the old vista ones (and this worked nicely in beta and rc, only rtm that has this issue). I have the same event notifications from event viewer: The description for Event ID 194 from source AtcL001 cannot be found.

I did also try the different drivers provided with W7 RTM, as well as the latest i could find on the partners.atheros.com site. This was never an issue in Beta/RC - it's new to RTM.

is your RTM install a clean install?

is your RTM install a clean install? Mine is a clean install yes from en_windows_7_ultimate_x64_dvd_x15-65922.iso. I did just try the trick posted in this thread: http://social.technet.microsoft.com/Forums/en/w7itpronetworking/thread/fb1d47c2-1c85-4835-9696-e28ce343464f I'll know for sure tomorrow if it helps or not, since it's never lived more than 12 hours before dying out. Mats

i tried that last night - although i dont remember if i rebooted after changing the power settings. It did not help. However, i need that option enabled since i've set up my PC for Wake On Lan via magic packet. I just ordered a NIC from amazon and i'm going to pick up one from bestbuy as well tonight. If the one from bestbuy doesn't work, i'll return that and try the one from amazon tomorrow since they are two different brands. I can't afford to be without a reliable net connection so for now I'd rather just pick up a new nic and get it working rather then spending too much time trying to tweak windows settings to get it to work. One thing though i didnt try before was to see if its only web pages that stop working. Also, with me, the issue starts occuring within minutes, not hours. Strangely though the day before last the only time this was happening was when i was streaming video to my PS3 from my PC. Starting last night the issue would happen every few minutes regardless of what i was doing. Out of curiosity, do you happen to have another machine you can open a remote desktop connection to? I'm curious if you have the same symptoms i do where it seems existing open connections are ok and it's just an inability to make new connections.

Out of curiosity, do you happen to have another machine you can open a remote desktop connection to? I'm curious if you have the same symptoms i do where it seems existing open connections are ok and it's just an inability to make new connections. Sure i can open one and leave it.

cool - oh and one last thing - does your connection also die for any other pc's on your local network? When this happened, i was still able to pull my routers webpage interface. I don't remember if i tried connecting to another pc on my network though. I'll try that tonight if i dont swap in a new nic first. Really annoying that the networking worked just fine in beta1 and rc1 for me - never had a problem. now that it's not beta anymore - now i get a problem ;)p

It has not dropped since disabling power management on the device.

I'll have to check this when i get home, but last night it did not drop once for me either, only i believe i have the power management enabled. I even managed to stream an entire tv show to the PS3 without it dropping, and that was the one sure fire way to get it to drop before. I'm almost thinking it's gremlins since i had 'fun' time trying to get a replacement nic. Ordered one from amazon but amazon was saying it would take a week to get here. So there's a dynex nic sold by bestbuy that i've found at least one person saying works fine under win7 x64. Betsbuy's website says the store near me has them in stock. Guy in the store cant find any though. Pick up a cheap dlink card instead only to find out they dont have any x64 drivers - they dont even have vista drivers. Place an order online to pick up the dynex card at another bestbuy - email comes back and says they are out of stock. Call up their 800 number to switch the pick up order to another store. Website says they have it stock. Wait on hold for 15 minutes and they come back and say that store is out of stock too. So i tell them to ship the nic to me. About an hour later i get an email from amazon with the tracking number for the NIC scheduled to arrive later today and not a week from now. Must be gremlins :) Actually, is the power management disabled to start with? because i uninstalled the atheros nic when i first tried installing the dlink before i found out they had no drivers. So maybe when i re-enabled the atheros is starts off with power management disabled. Although since i was just able to remotely power on my PC via wake on lan ... i just checked, all 3 check boxes are enabled. Just for comparison, the driver version i have installed is showing up as 2.4.7.27 6/22/09 Not sure why it was working for me last night if all the power options were enabled. Maybe uninstalling it from device manager and disabling it in the bios and then reinstalling it had something to do with it? Seems unlikely but that's really the only thing i did.

Tried to stream from PC to popcorn, died after 10 seconds. Nothing except the Event 194 in eventlog.

since mine worked all day yesterday without a problem, you might want to give this a try since it's the only thing i can think of that might account for why it worked: uninstall the NIC in device manager. reboot, go into the bios, disable the onboard nic, boot up into windows. At this point i installed another nic although didn't have drivers for it and removed it - doubt this had any impact but who knows reboot, re-enable nic in bios, and let windows reinstall it. Not sure if this matters, but in between each uninstall i completely shutdown the pc as opposed to just rebooting (since i had to physically install/remove that other nic). Just trying to include as much detail as possible so maybe you can replicate whatever I did that got it working last night. I'll see if it keeps working when i get home today.

I'll try to downgrade to the drivers provided by ASUS for Vista64. 2.0.6000.0 - dated sometime in 2007. I think these were the ones i ran in Beta and RC. Maybe it makes a difference.

ok, let me know how it goes. I think there was another thread somewhere where someone had downloaded drivers directly from atheros - maybe you can give those a try if the older one doesn't work. I haven't tried that yet myself.

well problem is still there in some form or another. Earlier today i remote booted my pc over the network. then i shut it down. Then i booted it back up again - and when it came back up again the network was gone and did not recover all day until i got home and reset the network connection.

fwiw, i just had someone suggest disabling large IP4 offload - i'm guessing this is the task offload setting in the NIC hardware advanced properties. It was enabled - i just disabled it - i'll see what happens.

ok, let me know how it goes. I think there was another thread somewhere where someone had downloaded drivers directly from atheros - maybe you can give those a try if the older one doesn't work. I haven't tried that yet myself. I already tried those and made no difference. So far it's running ok - but i'll know for sure tonight after trying to stream some to PS3/Popcorn. :)

well mine is still buggy. not as bad as it was that one night, but it still needs to be reset occasionally. Also looks like the drivers from atheros are the sames ones available on the asus site - same driver version. I didnt bother downloading them. On my system it seems to fail if i resume from hibernation. So far i've had to reset the network connection when i do that. And then it seems to fail randomly just doing normal stuff.

Hello!I've expirienced the same problem with my Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller on ASUS P5K MB.It's defenitely driver problem because I have such problem with with several Beta/RCbuilds also. At that time "Atheros L1 driver" update installed from Windows Update (optional) have solved problem. But not now. Neither various drivers installation, nor power management or advanced network controller optionsconfiguration - nothing helps. I've reflashed BIOS several times (last availible and previous version) - no success. It's really fail randomly during normal network operations (internet browsing, downloading some files, online gaming - not huge high like streaming, torrenting or so on) exactly as Ian_L reported..

I'm just going to pick up a replacement NIC later today. I finally found a bestbuy with a card in stock that others have said works with win7 x64 (dynex card). It's $30 at bestbuy.

So far the dynex card (model dx-pcigb) is working fine. Apparently this card uses a realtek PCI GBE family chipset. So i would guess any other card using this chip would probably work also.

Replacing hardware is hardly a solution, nor should it be marked as answer in this thread. :) However, driver version 2.0.6000.0 seems to be working nicely. No dropouts when streaming, browsing or anything else. Driver link is ftp://ftp.asus.com/pub/ASUS/lan/Attansic/AttansicL1_lan_V2060000_vista.zip - There are other drivers in the same folder, but this one sure did solve my problem.

Mats - i'll install this driver and re-enable the onboard nic and see if it solves it for me as well (btw i didnt mark that as an answer, one of the mods did).

I've had no problems since changing that driver. I'd guess yours should work as well now.

I haven't gotten around to trying out that driver yet. I'll try to remember to do it tonight.

We've seen this behavior on an Abit NFS7 board back when Vista came out and it was the reason we rarely used Vista on the box. I gave up trying to find the problem. The box dual boots w/ XP andis fine in XP. Not only do connections in IE fail, but the timeouts get to be a pain - programs likeQuickenhang randomly when they need togo on the net. It will work one minute and 30 seconds later be doing the no network connection thing. Again rock solid in XP. I installed W7 hoping the issue would have gone away but it is there. What scares me is that this has been a reported issue for almost 3 years now if you Google the issue- yet still no solution. If MS wants me to kiss an upgrade for about 1000 boxes from Vista to W7, this issue on my home box needs to go away or an explanation given as I am terrifed of upgrading 1000 boxes and finding the problem a week later. My career would be mud.

I haven't gotten around to trying out that driver yet. I'll try to remember to do it tonight. Still waiting for you to try it out and give feedback as to your experiences. I have had no problems since rolling the driver back to said version.

sorry, completely forgot about it since i was just using the nic i bought instead. do you happen to have another download location for that file? it doesn't seem to be available there now. I cant even connect to ftp.asus.com - i'll try to remember to try again tomorrow. maybe they are just having server issues.

Hey guys, I'm having the same issue. I'm running an Asus P5E-V HDMI with Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller. Windows 7 Professional x64 RTM (en_windows_7_professional_x64_dvd_X15-65805.iso). My network is generally stable, but drops when I copy files FROM my Windows 7 machine. I assume the same thing would happen if I tried to stream from it, but haven't tried that. I have left the machine on for the past several days, running some downloads, and have experienced no network troubles at all... As soon as I try to copy files (from my network shares on the Win 7 machine), the network connection drops with the same error in the System log. The driver for my network card was installed automatically when I installed Windows 7. The information I have on it is as follows: Driver Date: 22/06/2009 Driver Version: 2.4.7.27 Driver Provider: Atheros INF File: oem3.inf I've disabled power management on the adapter, but it didn't help. I'm going to try updating the driver now, and see if that solves anything.

Okay... I uninstalled my exiting drivers, and Windows installed new ones for me automatically (how nice...). They were a different (older) version, funnily enough: Driver Date: 19/06/2009 Druver Version: 2.4.7.172 Driver Provider: Microsoft INF File: netl160a.inf So far, I've had no problems with these drivers. I had power management off, and my computer completely froze when I tried to copy some files... When I restarted there were no errors in the system log, though... And I haven't had the problem again. With power management off, I didn't get any errors at all... I'll leave files copying overnight to see what happens.

And how did you download those drivers? =) if i tell seven to update automatically he downloads the 22/06/2009 drivers, atm i'm running the basic drivers from Atheros (12/11/2008) and looks like internet navigation is working fine even while downloading stuff, i'm going to try moving some files on the network from my pc to another and see if the gateway connection crashes. EDIT: it's 2hrs that i've reverted back to old drivers (Official Atheros 12/11/2008 drivers) and the network is working fine with power management off, moved around (and still going on) 50gb of stuff from this pc to my laptop and the gateway error never showed up, now i'm going to try some massive test like downloading from internet while moving files on the network and playing an online game.

I had exactly the same problem. With Atheros L1 on an Asus P5B-E with 7 x64the network connection would consistently die when I copy large files to my conceptronic NAS or when I tried to sync my recent MacBook Pro using the new HomeShare feature of Itunes 9. Those where the most predictable, although it would die under other circumstances.Anyway, after trying all possible driver settings I rolled back the driver through device mgmt. This resulted in using now the same driver as James mentioned.And ... no problems.Be carefull though: when running windows update the Atheros driver comes back up, so I have hidden it.Hope this helps.J.

Glad to ear it =) I got my Windows Seven Professional copy today via msdnaa and after a fresh install i got the 19/06/2009 drivers installed finally, gonna stick to them till a new release!

I'm having this exact same problem. I'm going to try the same drivers you are using later on tonight.

Yup rolling back to the previous driver that is 3 days older works perfectly! Thanks all and thanks James.

How do you get the driver dated 06/19/2009? I just looked in device manager and the date on the driver for me is 6/22/2009 version: 2.4.7.27 provider: atheros I dont have an option to rollback - it's grayed out.

I didn't actually roll-back my drivers - I uninstalled the ones which I downloaded from Windows Update, and Windows 7 installed the default ones (so I assume) that ship with Windows. James.

hmm. I went to the uninstall button for the nic. Checked the box to tell it to delete the driver software for this device, and then had it scan for new hardware. It reinstalled the nic with the same driver as the one i posted in my reply before this. Not sure how else to go about snagging whatever version you are using. What is the actual version number of your driver?

seems that the they published new drivers in windows update 13/10/2009 2.4.7.29 is these working? edit: still gateway crashing :(

I have found an answer in this thread Disable Large Send OffloadIf you scroll down to Monday, September 28, 2009 you get an explanation on how to do this.I could not finish a backup to my Windows Home Server, but this fixed it. I don't exactly now what it does, but i solved my problem.

Yep, this is the only solution!Atheros L1 driver 2.4.7.10 is bad software.Disable Task Offload in the driver property advanced tab.This will stop, die or halt your network.
