windows 7 - How to share internet connection between a 3g stick and an ad-hoc wireless network in Win7

  • Jonathan

    I have a 3g stick that supplies internet to one of two laptops I have. It comes with an operator software through which I connect. It appears under Network Connections as another connection, but instead of the usual WiFi bars there's an icon of a telephone.

    I'm able to establish an ad-hoc network with my other laptop. I'm trying to share the internet from the 3g stick with my other laptop.

    This is not straight forward as:

    • If I try to bridge the connections I have to mark both of them in Network Connection, but then when I right click all the options are greyed out
    • If I right-click on the 3g network \ properties \ Sharing tab - and choose "Allow other network users to connect through this computer's Internet connection - then I can choose from a drop down menu which connection should I share the internet with - the ad-hoc network does not appear in that list

    How do I share the Internet between these two laptops?
    One of them has an Intel Centrino Advanced-N 6200 AGN, the other has a Dell Wireless 1520 Wireless-N WLAN Mini-Card

    Here is how to disable ad hoc networks on Vista, It should work on W7 as well

    Windows Vista won’t automatically create ad hoc wireless connections with other computers, but for greater security you may want to disable ad-hoc wireless connections entirely. You can do this by running the following Netsh command at an elevated command prompt:

    netsh wlan add filter permission=denyall networktype=adhoc

    To re-enable ad hoc wireless connections, run this command:

    netsh wlan del filter permission=denyall networktype=adhoc

    If you go to Network and Sharing Center then select from the left hand "Manage Wireless Networks", you should see every wireless network your computer is set to automatically connect to.

    If there are no Ad-Hoc Networks listed, your machine will not connect to one automatically.

    As long as you do not create or join an Ad-Hoc network, your machine will never automatically connect to one (Unless someone Spoofs one with the same name as a network you use etc, but that is always the risk of using wireless - and it is highly unlikely).

    There is a more complicated way of actually disabling it - If you have access to group policy editor and the Wireless templates, you can set it to only connect to "Access point (infrastructure) network only." If you want a full guide for this, let me know and I will write one.
