Windows WiFi wireless hotspot

October 22nd, 2012

Wizard Do you know your Windows 7 (or newer) can act as a wireless router? It is very easy to share your internet connection with your other wireless devices (your tablet, phone or game console), as if you had an actual wireless router device.

Typically, if you have a laptop with Windows 7 and cable internet you most probably can turn it into an access point for your wireless devices.


  • Windows 7
  • Working internet connection (most probably cable, otherwise you wouldn’t need to set up a wireless access point in the first place, you’ll already have one)
  • Wireless card

You need to do the following:

  1. Open Control Panel -> Network and Sharing Center and select the link Change Adapter settings in the left column, near the top.
  2. Make sure you see at least 3 connections – (1) the cable internet connection, most probably through your ethernet adapter, (2) the physical Wireless Network (its adapter will be something like Intel or Atheros or Broadcom or whatever your laptop has) and (3) one virtual Wireless Network with the Microsoft Virtual WiFi Miniport Adapter. Take note how each one is called – we will be further calling them (1), (2) and (3).
  3. Right-click (1) and select Properties. Go to the Sharing tab and make sure Allow other users to connect through this computer’s Internet connection is checked. Then select the name of the connection (3) from the drop-down list below.
  4. Open Notepad and paste the following two lines:

    netsh wlan set hostednetwork mode=allow ssid=MyNet key=MyPass
    netsh wlan start hostednetwork

    Change MyNet to the name you would like to call your network and MyPass to the respective password to access it. Save the file as wireless.bat (or whatever you like) selecting Save as type: All files(*.*).

  5. Make sure your laptop’s wireless card is switched on.
  6. Right-click the file you created in the previous step and select Run as Administrator. Windows will automatically create the wireless network for you and secure it with a WPA2-PSK password.

You should now be able to connect with another device to the newly created wireless network. It will remain active until you switch off your wireless card or reboot windows. If you want to take down without switching off your wireless card, you can do so by pasting

netsh wlan stop hostednetwork

To take this one idea further, you can set this up to share not only your cable network, but your wireless one as well. You would want to do this, if for instance you would like to create a guest network to give your clients or visitors access to the Internet, but not to your main network. The setup is pretty much the same, only instead of (1) you would use (2) in the above example.

One click switch network settings

Wizard The last tip One-click switch between network settings for different locations (Windows) has gained a lot of attention from people searching to make their lives easier. Through testing in Windows 7, I found it not so convenient. I now present a simpler, more robust solution for Windows 7.

(0) I strongly suggest you rename your existing connections to something shorter and simpler. Microsoft have introduced naming of the type ‘Local Area Connection’, ‘Wireless Network Connection’ etc. While there certainly is reason behind that decision, for a home/office computer I personally find LAN and WIFI better. Go to Start button and type View network connections in the search field. Click on View network connections contol panel widget. Then rename ‘Local Area Connection’ to LAN and ‘Wireless Network Connection’ to WIFI.

(1) Open Notepad and copy the following 3 lines. Each line should start with the command netsh:

netsh interface ip set address LAN static <ipaddress> <subnetmask> <gateway> <metric>
netsh interface ip set dns LAN static <dnsaddress1>
netsh interface ip add dns LAN static <dnsaddress2>

On the blog the <gateway> and <metric> are on a second line, but they belong to the first.

Substitute <ipaddress>, <subnetmask>, <gateway>, <metric>, <dnsaddress1> and <dnsaddress2> with the values, provided by your ISP or corporate network administrator. Metric can be substituted with 1.


netsh interface ip set address LAN static 1
netsh interface ip set dns LAN static
netsh interface ip add dns LAN static

(2) Save the file as something descriptive for the location, e.g. home.bat, office.bat or university.bat, giving it a .bat extension, instead of the default .txt. Make sure Save as type: is set to All files (*.*), otherwise Notepad will append a .txt extension automatically.

(3) Now open a new Notepad window and paste the following lines to have the settings automatically acquired by the network:

netsh interface ip set address LAN dhcp
netsh interface ip set dns LAN dhcp

(4) Save as auto.bat, again observing the Save as type: All files (*.*).

(5) Keep all the files together at a convenient place (e.g. a folder on your Desktop or elsewhere).

(6) Activate the appropriate settings by right-clicking the corresponding file and selecting Run as Administrator from the context menu.

Same approach can be used for creating WiFi presets, substituting the word LAN from the commands with WIFI.

Note: In the commands above, LAN is the name of the network connection. If you have not changed it, substitute with the default ‘Local Areas Connection’ or any other name you have chosen. If the name contains spaces, make sure it is surrounded with quotes, otherwise they can be omitted.

One-click switch between network settings for different locations (Windows)

Wizard Update: One click switch network settings for windows 7

Mobile computers are everywhere now. Many people need to connect to networks (wired or wireless) in more than one place – at home and at work. One of the annoyances of current Windows interface is that you cannot easily store connection profiles – the way you can in MacOS X (called “Locations”) for quite a long time.

There is a workaround for that, involving a simple preliminary network setup + creation of a shortcut. I will briefly describe it here in 3 steps (you will have to repeat for each connection profile you would like to create). Here is how it goes:

Open a command prompt
(click STARTRun… then type cmd and click OK),
type md %windir%\netsettings (or copy it from here and paste it in the command prompt with a right-click) and hit Enter. Don’t close the command prompt yet.

  1. Make all network settings for the current profile (e.g. Office) – go to Network Connections, select the appropriate connection (wired and/or wireless) and set IP-address, network mask, default gateway, DNS servers, etc.
  2. Execute in the command prompt the following command
    netsh -c interface dump > %windir%\netsettings\office.txt
    and hit Enter.
  3. Create a shortcut on your desktop by minimizing all open windows, right-clicking on an empty place on the desktop and selecting New -> Shortcut…
    In the new window that opens, type (or better paste) the following
    netsh -f %windir%\netsettings\office.txt
    and click Next…
    Type a name for the profile (for instance Office settings) and click Finish.

Repeat steps 1-3 for as many profiles you need to create, changing office.txt with home.txt (etc.) in steps 2 and 3. Give each profile shortcut a distinguishable name.

You can now switch between different network profiles by simply clicking the appropriate icon on the desktop!

Note that this approach creates a full network profile (including settings for all network interfaces – wired and wireless), so in rare situations you might need to create different combinations of settings. It is also useful to have a setting with all connections set to auto, in case you need to access networks in hotels, airports and other public places.
