Network problem with VMware Fusion bridged autodetect mode

Vmware fusion 4.1.0 under OS X has a bug when using Bridged autodetect mode.

For example, suppose you have a cabled ethernet and also a WiFi connection. If you set the Guest OS to use ethernet as bridged with autodetect mode, it works fine at the beginning, but when you switch your Host internet connection from cable to WiFi, and switch back, the Host ethernet would not able to determine the status, let alone establish a connection.
The solution is easy, set the Guest OS to use ethernet as bridged but with a specific network adaptor and problem will fix immediately.
