atheros ar9285 causing high dpc latency

[skolyr]

After scouring the internet for a solution to general lag and sound stuttering I've been experiencing I have discovered that it is caused by my Atheros AR9285 WLAN Card.

Using DPC Latency Checker I have this output.

The top is with my WLAN card enabled in device manager and the bottom is with it disabled.

All my drivers are up to date so I have no idea what is causing this.

Most solutions I have found were to disable the WLAN card and use a hard wire. This is not an option for me because I only have access to wireless internet.

Thank you in advanced for reading and responding!

SPECS:

Model: Dell Inspiron M5030 Laptop

OS: Win7 x64

Proccessor: AMD V160 2.40 GHz

RAM: 3.0 GB

EDIT: Severe typo. wrong WLAN card model number.

enable all Offload options and Interrupt moderation in the driver option in device manager. Does it make a difference?

Thanks for your input Andre, you have already been a big help to me with your past forum posts. However I have the Interrupt Moderation and the Offload options only in my unused Ethernet card, they are not in the advanced list for my WLAN card.

also try older drivers.

Older drivers just prevented connection to the internet all together.

However when I took the computer to best buy to see if Geek Squad could make any sense of it, the problems subsided. I wonder if it's how I need to configure this card with my current router. it is a 2Wire 2701 HG-B or if I just purely need a new router because not only is it old but both B and 2Wire routers are pretty low quality.

I don't know your Router, so I can't say if this is the cause

Can you ask a friend that he can give you his router for some testings? Also try to reset the router, also uninstall the Atheros AR9268 WLAN Card and let Windows reinstall the drivers. Maybe this helps...

Thanks for all your help Andre, it seems to be the router as I do not have any problems on other wireless connections.
