When i'm connected to a wireless connection with my dell e1505 notebook, that anytime I play music from hard drive it slows,skips, and stutters. Only when connected wireless. I have a sprint connection card, and it does not do any of that. It works fine. Only wireless! I use my notebook to Dj at a bar/nightclub, and have to get it working without these issues.   Please help!!!!  Thanks, Bobby
