My wired and wireless network connectors are killing my sound:

[kwitel]

After much testing, the crackling, popping and intermittent sound drops that I am experiencing are being caused by BOTH my Intel 82567 Gigabit Network Connection and Intel Centrino N 6200 wireless card (although the former causes way more problems).

I have downloaded the latest drivers for both and for my sound card and, have updated the BIOS...but no change. My latency is off the charts; lots of red bars in DPC checker. the problem seems to be getting worse with time.

What to do?

I am using Windows 7 64 bit on a Dell Latitude E6400.

Thanks.

Welcome to the Seven Forums.

Does this happen when the laptop is wired to a different network? Please test using a network that is miles away from the network where you are hearing this popping.

I honestly dont know.
How does one do that?

For me, I would take the laptop to my office and plug it into that network, stream some music and see if I hear the popping. You might have a friend across town that would let you bring a network cable and laptop over for such a test.

The goal is to see if the interference is coming from something in your dwelling or if it is indeed from the laptop itself.

You could disable both network adapters via device manager, but that might not be as good of a test because we want the network adapter to be working under a bit of a load - like streaming music.

When I disconnect both I get zero latency issues/interference.
I will have to try taking the lappy with me somewhere over the weekend and test it.
Thanks.

Tried it at a friends house yesterday (both wired and wireless) and I get the same issue.

What next?

Then it sounds like a hardware problem. You might want to contact Dell and see what they have to say about it.

Its definitively the network drivers.

Also, it seems to get worse when I click on things (ie, open a new window, email, etc.)

How do you figure that it is the network drivers that are causing this popping issue?

When I disable both I have no problems. Literally, zero problems and no issues with latency.
I have also disabled each one, independently of the other and they BOTH cause problems but the wired adapter causes more than the wireless.

Further, I have read on quite a few other forums that others have had similar problems.

I just have no clue what to do now...

I don't think that disabling the hardware also disables the drivers... but I could be wrong.

I would still want to talk with Dell. Is this computer under warranty?

Well whatever happened, disabling them cut out the problem immediately.

Its is still under warranty...I just dread calling Dell customer service. I guess ill ring them tomorrow.
