Routing network traffic on Windows Vista

"Vista supports only one internet connection, and in addition has the annoying habit of always preferring wired connections over non-wired, on the supposition that they are faster (have better metric).

See this article for a solution with many screenshots :
""Windows Vista Multiple Networks: Wireless To Public WIFI and Wired To Private LAN"".

The basic solution is to use the command:

route delete 0.0.0.0 IF 11

where the IF 11 refers to Inteface List # 11 (which is displayed by route print command output, in the Interface List section). Replace 11 by the number of the interface that you don't want to use for surfing."
