At my work I have a computer that I use for program development. The majority of the time I connect to our corporate LAN through a wireless adapter. Occasionally I use the wired network connection in my program development. Right now I need to connect to a separate "test network" through the wired connection and still have my wireless connection to the corporate LAN. It only partly works.
Windows 7 seems to want to use only the wired connection when it is connected. This means I can not connect to the corporate LAN for file, email, and internet access. We just recently upgraded from XP to Win7, I used to do this in XP all the time and had no issues connecting to both networks at the same time.
For now I have put a hub on my desk and connect or disconnect the "test network" as needed, but this is a real PITA and this setup used to work fine in Windows XP.--
