With my rig in sig, in a crowded place and with about 40mb of addons I always get above 80 fps.
I also noticed by turning on DX11 mode it gave an increase by about 20 fps in Twilight Highlands (it gave a slight increase everywhere but in TH it was noticeable the most).
I have never have any problems in Arenas or Raids so to say you NEED 120 fps is futile.
I play via a wired connection but I have played on wireless at other peoples houses and I haven't noticed any difference.
The plug adapters you mention are called "Powerline Adapters", google it!
You should also run this little program that is designed to lower the latency of wow, it lowered mine from a usual 140ms to 60ms.
