You could try that, some wi-fi adapters can cause RFI. Check this link especially the two replies by CyberVisions: Internet constantly disconnecting - HP Support Forum
I know your concerns don't include dis-connects, but there is some good advice there. RFI's can be hard to track down.
It might be easier to make a Faraday Cage
out of aluminum foil to check.
Just get a box large enough that your dv7 will fit in, and cover it securely with the foil.
Work with the dv7 while it's inside the box, this will in all probability defeat your wi-fi.
Make sure you do not have any electrical devices or metal on you such as a portable phone.
- Change positions every 90°'s, (because the box has an opening)
- Change rooms.
- Go to a different level of your house if your in one.
- Does it happen at a friends/relatives home?
See if that stops the pops, and clicks.
If it stops then concentrate your search in the areas that the dv7 is shielded from.
It is harder to do with your dv7 because it is a Laptop, but on my desktop I had to cover our speakers with foil to stop the RFI.
Your not using any after-market accessories like a power cord or battery for your dv7 are you?
They may be inferior to approved HP products.
