5. First, vmnet0 is used for & quot; Bridging & quot; There is no need to set IP address
the host can be connected, and the virtual machine can use & quot; Bridging & quot;, Unable to access the Internet:

2. The system in the virtual machine is not installed properly, and the system driver in the virtual machine is not installed properly (win7)
VMware 6.0.2 is too old, There are two
articles about virtual machine system and the download address of VM XP win7 Chinese green compact edition at the end of the article:
