I'm always fighting with Windows 7 when I'm on a wired connection. I don't want it to prefer wireless by default.
Every article I found talked about playing with the TCP/IP V4 interface metric, but that wasn't what I was looking for.
I searched around on the web and found the following at the bottom of a thread.
In the start menu, search for 'network connections' and press enter.
In the window the comes up, use Alt-key for menu. Choose Advanced. (alt-n-s) On the Adapters and Bindings tab, re-order the connections, putting your wired connection at the top.
This seems to do the trick so far. I'd like to find how to do this via "netsh" since the above isn't at all intuitive. I also want to spend some time digging into these advanced options.
