I don't really know. I was considering connecting the base to the satellite with Ethernet cable, but decided to try using the wireless capability first. The distance between both in my house is about 45-50 ft and I have not had any issues with the two communicating with each other. I've read in several places that it is OK to connect Ethernet cable. So, I don't know if you are defeating the power of the system, but if you are concerned, you might try connecting without the cable and see what happens.
