I also prefer wired to wireless, whenever possible. The signal is going to be better.
I even buried ethernet cords in a pipe between our 2 main buildings (House and school/office "annex" trailer) because I wanted a solid Ethernet connection for work. It didn't cost that much, and we already needed a trench to install electricity. But still, the small cost was well worth it.
Wireless is fine for my phone -- for small consuming operations (check the weather, check the news, check email, etc.) but for serious work, you can't beat a wired connection.
