Wireless AC (which is what this device is compatible with) can span up to 230 feet. However, the router has to be AC also, if not, then the USB wifi adapter will drop down to either N (also 230 ft max) or G (170 ft max). Note that lots of things can affect the maximum range, if the 150 feet is clear of any obstructions (specially anything metal), then it is probably OK. But the more obstructions between your device and the router, the more likely it will affect the range. So make sure the router is at least wireless N (preferably it should be AC) and you should have a good shot at being able to stream.
