Problem:  

How to enable Windows 10 to work as a wireless access point.  Use the Netsh WLAN commands to create Ad Hoc networks.  Internet Connection Sharing (ICS) includes a default route and DHCP service for fully pledged access point (AP) routing!

Netsh WLAN is not ground-breaking innovation -but it sure comes in handy!  What's more, the default wireless security settings use WPA2 with AES encryption and CCMP ciphers.  WPA2 provides the best wireless security standard and data rates.  Compare that to your old Linksys AP.

This solution can also be used for basic penetration testing.  Think MITM hotspot for Intercepter-NG ;)

Solution:  

Install additional wireless NIC (e.g., USB).  Create an Ad-Hoc wireless network SSID.  Start broadcasting:

1. Create wireless SSID:
C:\Users\billgates>netsh wlan set hostednetwork mode=allow ssid=Personal-WiFi key=H@rd2Cr@ckKey!!%42
2. Start the wireless SSID: C:\Users\billgates>netsh wlan start hostednetwork

Other Wi-Fi enabled computers may connect to the Ad-Hoc wireless network.  This feature is great for simple file sharing but it falls short of shared Internet access.  Use the ICS to turn this Ad-Hoc network into an Internet AP:

1. Right-click on the network icon located in the taskbar.  Left-click on Open Network and Sharing Center.
   
2. Click on the Wi-Fi connection located next to Connections:
   
3. Click on the Properties button.  Click on the Sharing tab.  Enable ICS Sharing.
4.  Assign the ICS to an available NIC from the pull down menu.  N.B., The pull down list is only visible when the computer has more three or more NICs (either Wi-Fi or Ethernet).

That's It!
