Is there an advantage to doing so? It plays fine now via WiFi but my signal is not that strong in this part of the house.

That being said, if it's working fine the way it is, why change it?
Note that when being used as the "home theater" aspect, with the line in from the TV, the actual signal that everything in the Home Theater is connecting to is the PLAYBAR, and not your home wifi. It's only when you stream music to it that the data will go across your wifi (on a 2.4ghz signal) to your PLAYBAR, which then sends it to all the "bonded" devices of the SUB and surrounds on a 5Ghz signal that it generates.
So ultimately, even if you were to "wire" the system, all you really want to do is wire the PLAYBAR.
