Screwed up wireless interference

[spleenharvester]

I've put up with popping noises from my speakers for nearly three years, but now it's starting to get annoying, and after a lot of work I've figured out that the speakers aren't shielded properly. Is there any workaround for this, other than new speakers or ethernet/mains networking? I don't have a lot of money atm specially made antennas perhaps?
I'm going to get a PCI-E x1 Abit AirPace to replace my crappy Netgear thing anyway (WG311v3 to be precise), maybe that might help.
Thanks in advance.

I've never heard of 802.11 interfering with speakers. Are you sure its your wireless? Have you disabled the wireless card to make sure it is the wireless?

Id say it is more likely to be caused by your power supply or just a dodgy decoder unit.

I'm 100% certain it's the wireless card, when I take the speaker jack out the noise remains, and as soon as I remove the aerial it stops. Does it mainly when on youtube buffering videos, for example. I've even tried a different wall socket to no avail.
