Having and ethernet cable plugged into your devices is best and more secure because that would require anyone that would want to use your internet to be plugged in. the draw back is having the router far away from your computer but you get security and possibly a faster and reliable internet then a wifi that is access anywhere (within range) but may sacrifice the speed quality and security so choose your pick...
