Wi-fi, I'd say no. The wi-fi will use microwave frequency signals to transmit data, and any radiation from the substation will be lower in the EM spectrum*. So it should have no effect. Have a read of this though.
Noise wise, they emit a low humming sound, but standard insulation and double glazing should stop that.
