Only 10 foot range may indicate something else is causing you problems. Although a WiFi network frequency is far removed from the 310mHz RF frequency that the SC1200 uses, if the wireless router in in very close proximity to the SC1200 (like a foot or so), it could be desensitizing it. Also the orientation of the SC1200 has an effect on range...it shouldn't, but it does. If your SC1200 is setting vertical on counter or desk, try setting it up on edge so it is horizontal, and try it.
