A CAT5e or CAT6 cable would provide the performance and capability that you need.
Next choice would be a pair of Ethernet powerline adapters to send an "Ethernet" signal over the existing powerlines in the home. This would be "iffy" in that you will not know how well it will work until you try.
Dead last choice would be wireless. Even under ideal conditions.....(line-of-sight with no obstructions in the signal path)....wireless is good to only about 150 feet or so. Even then, the signal will be weak and borderline as far as its useability and reliability.
Add in 4-5 walls and maybe a ceiling in the signal path, and the effective capability of wireless will be reduced down to maybe 40-50 feet in a normal home.
