Concerning wireless operation: Even when I am not more than about 20-30 feet from my wireless router I have usually have either low or, more typically, very low signal strength. Speed is usually between 11.0 and 18.0 MPS. As a result I have trouble staying connected to streaming music stations. Is there anything I can do to increase speed and strength with my current hardware, or should I upgrade my hardware (I prefer not to). And, if I do need to upgrade, what should I get? Thanks for your help and advice ...
