Windows 7: Manage Wireless Networks does not show up

I have searched the net for this problem, but could not find an answer. Here is the description of the issue:
When I go to the "Network and Sharing Center", the "Manage Wireless Networks" link does not show up.
(normally, it should show up under "Control Panel Home" at the left pane).
When I type "Manage Wireless Networks" in the "Search Control Panel", I am able to find it.
But, when I click on it, it says "Wireless is not currently enabled."
When I click on "Add", it says "Windows cannot detect any wireless networks interfaces".
But, the wireless adapter is working fine. As a matter of fact, I am currently connected to the internet via wireless connection. So, this could not be the adapter issue or the modem issue.
The reason I am asking for help is that, I want the capability of selecting which wifi connection to use.
Right now, I cannot choose which wifi connection to use and this presents problems when windows pick a non-working wifi (just happened to me this afternoon). When I was running under Mac OS, I was able to pick a working wifi.

The question is:
How do I get Windows 7 to display the available wifi connections so that I can pick one from the list?

I am using Windows 7 Professional 64 bit on a Mac Air (via Parallel Destops).

Any help is greatly appreciated.

How is network between Windows 7 and mac setup?

The Basics

Parallels Desktop provides four basic network configurations:
The small print provides some additional technical detail that you don’t have to understand.
. Bridged to Built-in Ethernet Adapter

This works as if your VM were a separate PC plugged into the network. This configuration is most compatible and transparent.

Bridging to Built-in Ethernet takes advantage of wired ethernet capability to “spoof” hardware address, i.e. to send frames with VM hardware address through Mac ethernet adapter.

. Bridged to AirPort Adapter

This mode works as if MacOSX were configured to have one more IP address and that address being handled by your VM. Note that wireless security (WEP/WPA) is handled by MacOSX, no additional configuration is needed in guest OS.

Due to limitations of 802.11 standard which is implemented by AirPort it’s not possible to spoof hardware address in this configuration. Ethernet frames sent from the VM have Mac AirPort hardware address on them.

. Host-Only Network

In this mode your VM is attached to a private network accessible by MacOSX but invisible to the outside world and can not access outside world either, but… read on.

Host-Only network is implemented by bridging to Parallels Host-Guest Adapter which is a virtual Ethernet adapter installed with Parallels Desktop.

. Host-Only Network with Internet Sharing

This mode provides your VM with outside network access while still not allowing external access to guest OS. On the positive side of this mode is the possibility to share Bluetooth Modem or VPN connections from your Mac to a VM.

Internet Sharing in MacOSX is merely a NAT service supported by DHCP server and DNS proxy configured with a click of a mouse.

One last thing is Default bridging. This simply bridges either to Ethernet Adapter or to AirPort depending on which one is active and has higher priority set in MacOSX Network Preferences.

Most likely you use:
Bridged to AirPort Adapter ... or... Host-Only Network with Internet Sharing ... or... default bridging. Last one is the same as "Bridged to AirPort Adapter" when using wireless.

Are you aware of the fact Windows 7 is running as virtual machine in MacOSX? MacOSX handles all the network traffic!! So MacOSX has a wireless adapter. You have to connect wirelessly using MacOSX.... not Windows 7. Windows 7 just has a virtual network adapter.

The following is the result from ipconfig (that works)

Windows 7 is connecting through "Ethernet adapter Local Area Connection". It's virtual network card.
His ip address is 192.168.10.136 and default gateway is 192.168.10.1.

You have configured the VM as "Bridged to AirPort Adapter" or "default bridging" as explained before.

Thanks for the info. Now the question is: why can't I connect to the internet from Windows 7 while I there is no problem from MacOS? I am currently writing this message from Safari because I could not connect to the internet from Windows 7.

Thanks a lot for your help!

192.168.10.1 is the ip address of router?
In command prompt: ping 192.168.10.1
works? 4 sent, 4 receiveced, 0 lost?

Using WiFi in a Virtual Machine

Parallels Desktop provides you with an opportunity to connect your virtual machine to a wireless network.
Using the Bridged Ethernet mode, you can set up a WiFi connection and access the Internet wirelessly. When operating in this mode, your virtual machine appears on the network as a stand-alone computer with its own IP address and network name.

To configure your virtual machine to access the Internet through WiFi:

1. <LI class=listnumber>Choose Configure from the Virtual Machine menu to open the Virtual Machine Configuration dialog. Select Network Adapter in the Hardware list. In the Network Adapter pane, make sure that the Enabled, Connected and Bridged Ethernet options are selected. In the Bridged Ethernet drop-down list, choose AirPort.
2. Click OK.

After you perform these steps, your virtual machine will be able to connect to the Internet through the AirPort adapter of your Mac.
