I installed Virtualbox on my workplace laptop to run Lubuntu in Windows-7 64-bit. I have some issues to make the hostonly network work with wireless adapter.

The wireless adapter will turn off once wired adapter is connected.

When I disconnect the wired adapter, wireless network doesn't turn on. Current active network points to Virtualbox Hostonly adapter. Only after I disable the hostonly adapter, I can turn on wireless adapter.

How can I make the wireless adapter turn on without disable virtualbox hostonly adapter?

VirtualBox doesn't correctly notify Windows 7 that the Host-Only Adapter is virtual. As a result, it shows up as an unidentified public network. It sounds like that may be the source of your problem.

To correct the issue, you must make a minor addition to the registry. First you need to locate the key associated with the VirtualBox host adaptor:

  1. Under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class{4D36E972-E325-11CE-BFC1-08002BE10318}, locate the key containing the string DriverDesc with a value of "VirtualBox Host-Only Ethernet Adapter"
  2. Within the key you located (something like '00XX'), add a DWORD value with the name "*NdisDeviceType" and a value of "1".
  3. Reboot.

Additional rationale for making this change and examples of PowerShell scripts that can automatically make it for you can be found here or here. I have not tested either PowerShell script, so your mileage may vary.
