Comment No subsitute for hardwired Ethernet (Score 4, Informative) 279
I've tried both wireless client bridges (300Mbps N) and powerline Ethernet adapters for an HDHomerun tuner, and my results were: a) only one tuner could stream over the wireless and b) the powerline adapters were an epic fail. The punch line is that the HDHomerun works fine and dandy over 100BaseT. Between the crowded 2.4 GHz spectrum and the poor penetration of 5 GHz, wireless just doesn't cut it for anything that needs throughput.
String some Cat5e or Cat6, and leave the wireless for laptops and tablets.
Cat5e will work fine for gigabit. Cat6 will support 10G, but 10G costs a fortune.
