Re: 2 questions from noob
the music thing sounds wierd. does it happen for all your songs? could be a driver issue. try and install the latest driver.
as for the router issue you may need a driver for the pci card aswell. right click my computer, go to properties, then hardware, then device manager. look for a yellow ? or your pci card from the list and try to update the driver. the crap signal could be for several reasons. i get rubbish signal in some places. its due to my crap router and my house having the layout it has. other things can cause interference though
