    Definitely upgrade to the 9.2.1.470 version Atheros driver. You can then check if DPC Latency still exists in your system from some other driver with DPC Latency Checker.

    Keystroke misses can also be a hardware problem. Does it happen with specific keys on your laptop or is it random?

    Hi, and sorry for late response. Yep, the problem is not key-specific, it's really random but it doesn't happen always. Sometimes it work flawlessly with no key miss, sometimes it drives me crazy with lots of missing keys. It's really unstable. I also get DPC red bars which might be caused by Atheros AR9285 poor driver as you said.

    So, where can i download Atheros 9.2.1.470 driver as healthy? Do i need to mod its INF or install directly by running setup.exe?

    Do you use the same version?

    Looking forward to hearing from you, thanks!

    I use Atheros version 9.2.1.470 on my G74SX, but in checking, it appears this version does not support the AR9285. If I were in your situation, I'd try the 10.0.0.75 version. It is available at http://www.atheros.cz/atheros-wirele...et=37&system=5, but you can also obtain it from other sites.

    Really not sure. I thing 9.2.1.xxx series must be compatible and i see no reason to update to 10.x.x.xxx series unless we see specific problem. Btw, since i own my G53JW for 2 years, today i get really INTRESTING and UNEXPECTED BSOD related to athrx.sys (Atheros driver) during logon for the first time, using the stock one, which have caused zero issues so far.

    Any current stable and AR9285-compatible driver suggestion is really appreciated, thanks again!

    ATHRX.SYS could be a victim in the BSOD, rather than a cause, particularly since you report it functioned without issue for a long time. I'd recommend troubleshooting the BSOD further. See http://rog.asus.com/forum/showthread...l=1#post222136 for recommendations.

    I also see no problem in updating the Atheros WiFi driver to the latest 10.0.0.xxx version applicable to your Wireless Adapter.

    Just a note to you all after trying countless wifi drivers, dpc improvement software, turning off power management etc etc I discovered on a Win7 site that the problem was the website blocking option on Malwarebytes program. If you have this program installed just turn off the website blocking and your dpc latency checker will turn a beautiful green all the way. Hope this solves the problems of some of you.

    My G74SX BSOD on reboot was caused by an update I did within Device Manager to the Atheros Bluetooth Bus driver. Rolling the driver back in safe mode sorted the problem out. Hope this helps.
