Last winter I did some in-wall cat5e wiring from my router to my computer. It's probably about a 50' run, maybe a bit more. I then got some new nice speakers for my computer. At some point since then I've found that the speakers are picking up some talk radio station.
I've narrowed down the source of the interference to the network wiring. If I pull the cable the radio station goes away. Plug it in and it returns. I tried pulling the cablemodem cable from the router and the interference persists. I've tried various patch cables from the wall to computer with no change.
The wire I used was UTP cat5e. Nothing special...it was bulk from the local home store. Would shielded cable fix the problem? I'd hate to rewire, but if it would fix the problem then I would. If so, does any shielded cat5e do the job? What about the jack? Does it have to change? And I guess the patch needs to be shielded as well?
