I have always considered WiFi more of a convenience network, for light use such as web browsing. All my "serious" stuff is done over hard wire connections. One thing you can do to get the most out of a wireless network is to setup one in the 5 GHz band. It's much less crowded spectrum than 2.4 GHz and isn't competing with things like cordless phones. On a 5 GHz 802.11n connection I can get 300mbps consistently.
