Wires are great, and I try to use them when possible, but you can saturate most home Internet with decent midrange WiFi hardware. I get over 1Gbps between local machines just using the stock Comcast/Xfinity WAP, and about 330Mbps to the Internet (capped by service plan). I splurged a little on a ~$120 4-antenna NIC but even my cheap older ones can saturate the WAN link.
