Problems with atheros L1 ethernet adapter in Win7 x64

I have the MB P5k, and I´m having the exact same problem with the Atheros. I simply can´t understand, how this driver can be released as WHQL driver, and yet fail to work. This is a serious matter. I´m running Windows 7 on several computers here at home and running daily backup on a Windows Home Server. This client with the Atheros has not been able to finish a backup yet, simply due to this error.

Neither 2.4.7.27 or 2.4.7.29 works here. This is very bad for Asus, and even more for Atheros!

It seems worst of all for you--I doubt asus or atheros care that much about old product compatibility with a new os.
some people report going back to a much older version of the driver works.

(I made sure I'd removed the previous driver completely before I installed the newest, and that one works for me. Don't forget to add mpowrie's fix earlier in this thread.)

I have been struggeling with this issue as well (main pc freezes when streaming dvd's to my mediacenter)
Just wanted to let you know that disabling the Task Offload feature does solve the streaming/freeze problem in yr own network BUT... with this option turned off yr nic cant handle multipe internet request anymore for some reason.
When i download articles from usenet and stream radio or play an online game i get major lag and the stream halts, even when downloading (not even at max bandwidth) internet pages load very slow.
With the Task Offload Option set to "on" i dont have this problem.

My only option left was to buy a new nic and so i did, now all problems are resolved.

Hope this helps.

Cheers !

Hi Crew,
This works
First update driver from Atheros Communications

Go into Atheros NIC adapter properties. click 'configure' tab & disable all the task off-load settings.

After over 100GB file transfer using GigE & Jumbo frames, - No NIC crash, wopeee!!!

Suggests that the Atheros NIC just can't cope with too many tasks & crashes

All the best

Found this tip on another site and trying it out now. Instead of disabling Task Offload (which reduces your speed), disable Flow Control instead. Good luck!

Bond's tip above works, ie, disable ALL Flow control Tabs - thanks (yes & it does give better performance than disabling task off-load)

Confirmed, disabling flow control worked, but ONLY with driver v2.7.4.29.

Tested with Windows Server 2008 R2 x64 using the Win 7 x64 driver FWIW.

How do you get all these settings? MY L1 which is on my Asus P5K motherboard doesn't have options like Jumbo Frames ,
Large Send Offload IPv4 - Disabled
Large Send Offload v2 IPv4 - Enabled
Large Send Offload v2 IPv6 - Enabled
etc

Can you advise please?

It works for me with the following settings and driver version L1WinSetup_v2.4.7.29_WHQL.rar:
Flow Control ON
Task Offload OFF
