Hello all,

In my last instructable I showed you how to setup a wireless hotspot using a pre-existing wired internet connection. Some of you may have wondered if it was possible to setup a wireless hotspot using a pre-existing wireless internet connection. Well wonder no more because this Instructable will show you how!

Similar to my last instructable you will need:

A pre-existing wireless internet connection.
Windows 7 - As far as I am aware the windows 7 OS must be either Business, Enterprise, or Ultimate. - In this Instructable, I am using Windows 7 Enterprise.

The benefits of sharing a pre-existing wireless internet connection are numerous. At my school, some of the laptops have inbulit 3g adapters. This allows them to connect to the internet using their own 3g internet connection rather than being restricted to WiFi.

Imagine this situation:
You and a friend are out camping. Due to your geeky needs, you took your computer to play some games/surf the web etc.. Your laptop has an inbuilt 3g adapter so you can connect to the internt on the fly. However, your friend is not as prepared and cannot connect to the internet. What can you do?

You can't just unpack your router and set it up, because you're camping remember? So, with only your pre-existing internet connection and a virtual NIC you will be able to follow this guide and setup your own wireless hotspot.

Disclaimer: Don't actually set this up while you are camping if you want your battery to last. Running your primary NIC and a virtual NIC will chew through the battery faster than Shaggy through a packet of Scoobie Snacks!

I don't mean to spam here but I suppose I should repeat the information I gave in my last instructable:

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" pieces of hardware and whilst one is connected to the internet, the other can be sharing this internet connection with your other WiFi capable devices.

I've written this instructable assuming that most readers didn't read my first instructable. Therefore, I will repeat all the steps over again:

Anyway enough information, lets get to the instructable.

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!
<p>Thanks for this epic instructable, here is my <a href="http://www.techsive.com/2015/09/airtel-4g-and-huawei-e5573-mobile-wi-fi.html" rel="nofollow">review of the Airtel 4G wifi hotspot.</a></p>
<p>I realize this is an extremely old guide here. But I had a quick question. I have two wireless adapters, when enabling the miniport what adapter is it using? The internal or the usb dongle? and is there a way I can receive internet on one, and transmit a hotspot on the other?</p>
<p>hello. i've right every step but the Microsoft Virtual WiFi Miniport adapter icon does not appear. I have an acer aspire 7535g, which is somewhat old, but there's nothing on the internet saying that the computer doesn't have the ability to do it. So what is the problem? Please help me.<br><br>Thank you</p>
<p>wow thank you. it works at my hotspot. btw, how about without key=persistent? i mean, no password every ppl login to my hotspot?</p>
<p>i tried this so many times. my mobile get connected properly but net doesnt work on it. i am able to ping cell fone from my laptop but net doesnt work at all. formatted my fone but nogo. please help</p>
