>Presumably you (and Kevin) are referring to Internet speeds. On your own LAN you should be getting 1.0Gbps on Ethernet compared with about 24Mbps on wireless (depending on your router/wireless capabilities...)

24Mbps was a reasonable, real-world figure for performance back in the 802.11g days. The newer 802.11n and 802.11ac standards (Wireless-N and Wireless-AC respectively) can do much better: http://www.extremetech.com/computing/160837-what-is-802-11ac-and-how-much-faster-than-802-11n-is-it

Even the latest WiFi standards are still no match for wired gigabit Ethernet. Wired doesn't drop out when your next door neighbour microwaves a burrito and is more secure. As a side note it's amusing that the earliest WiFi security standard (now risible) was called WEP, short for Wired Equivalent Privacy.

Regardless of all this, if any single wireless user can get consistent bandwidth equal to or greater than the ISP's service, then wireless won't be a bottleneck to and from the public Internet. Wireless may even be OK media streaming within a home, although that case might benefit from wired, or wired could be used to connect an AP or range extender to areas where wireless signals would otherwise be weak.
