One more thing.
If you have just 1-2 WIFI users at home, should be fine. More than that (busy airway) u may find stuttering/buffering on your Video, in which case either (1)U tell everybody to stop using the Internet while you are mirroring it, or (2)upgrade your router with a QOS capable one.
To work around busy airways, if u have a dual-band router u maybe able to dedicate the 5 ghz band to mirroring and leave the 2.4 ghz for everything else, without buying a new QOS router, but I have no actual experience doing this.
