There is no negativity towards WiFi.
Just to reiterate for those who are hard of understanding - some manufacturers choose hardwired connections for their network products over WiFi to eliminate the potential issues with WiFi. A hardwired connection means that any wireless network issues are null and void, so if there are network issues, they can only be to do with the actual network or the product itself.
Hegel choose this route, as does Innuos, Lumin, Silent Angel, and also Yamaha used to with their AV receivers. And those are the ones I know of. There will be other manufacturers too, so if you own a product that requires a physical connection for network capabilities, those manufacturers chose that route too. They decided not to leave anything to chance. They chose this route for the homes and areas that have unreliable WiFi, not for those that have perfect WiFi that never slips a beat - much like my own WiFi at home, but I still cable it to reduce potential issues.
I really cannot make it simpler than that.
