Is it possible to make Windows 7 connect to an available WiFi network automatically only if LAN is disconnected? The only option I see right now is that Windows connects using both LAN and WiFi. This is undesirable because my router limits the amount of total active connections and I would like to only employ one at a time.

You could see if changing the network metric. Windows will automatically use the network connetion with the lowest metric, so see if my answer to this question on SU would help. –  tombull89 Feb 29 '12 at 15:29

Nope. Linux, Mac OSX, FreeBSD, etc can all do this, but Windows does not have any built-in link aggregation capability. There may be 3rd party software that can make it work, but not just Windows.

Thanks. Now that I know the name for this I was able to verify that indeed Windows does not support link aggregation using this article: en.wikipedia.org/wiki/Link_aggregation ) –  gnobal Feb 29 '12 at 15:19
    
Some laptops have an option in the BIOS to automatically disable the wLAN card when a LAN connection is present, mostly newer laptops. It still has the problem of disconnecting all active connections when you switch though. –  Chris S Feb 29 '12 at 15:35
    
My IBM thinkpad could do this 3 years ago, but it was with their connection manager. –  Basil Feb 29 '12 at 15:37

It's not free but it's got a 30 days trial and costs about 8$ if you decide to buy it: Wireless AutoSwitch XPV

I don't know of any way to do it natively in Windows.
