This is my first Instructable so all constructive critiscm is welcome.
In this Instructable I will be showing you how to set up your own wireless access point using Windows 7's "Virtual WiFi Miniport Adapter" .You will need a pre-existing wired (ethernet) internet connection to set up the wireless hotspot.
Some of you may now be wondering "Why would I want to set up a wireless hotspot when my laptop is already connected to the internet?"
OK just imagine this situation:
Just say you were staying at a hotel on a business trip and the hotel offered free internet access via ethernet (not wireless). If you wanted to connect an Ipad or similar device, you would need to either set up your own router (and come on, how many of you honestly can say they would bring a router with you on business trips?) OR you could follow this guide and setup your own wireless access point, thereby making the connection available to any WiFi capable device.
A Network Interface Card is a card used by your computer or laptop to communicate over a network. There are multiple types of NIC cards that connect to different technologys such as Ethernet or Wireless. Most laptops only have one NIC (Network Interface Card). This lack of multiple Network Interface Cards makes it impossible for a user to have an internet connection whilst sharing a hotspot. Thankfully due to virtualisation, you can "split" your NIC into "two" hardware and while one is connected to the internet, the other can be sharing this internet connection with your other WiFi capable devices.
Anyway enough information, lets get to the instructable.
Step 1: Step 1: Enabling the Microsoft Virtual WiFi Miniport Adapter.
This step will guide you through enabling the "Microsoft Virtual WiFi Miniport Adapter": From my knowledge the "Microsoft Virtual WiFi Miniport Adapter" is not compatible with all wireless cards but if it yours is compatible, and you follow my guide, it will work.
To enable the Virtual adapter open the "Run" dialogue ("Windows key"+ "R")
Then open the Command Prompt (type in "cmd" and click "Enter")
Once CMD is open type in the following command:
netsh wlan set hostednetwork mode=allow ssid=Hotspot key=Password keyUsage=persistent
Where "Hotspot" is the SSID (the name of your connection) and "Password" is the password locking the connection.
Once this is done, you have enabled the Microsoft Virtual WiFi Miniport Adapter!
