IIRC there is a utility (cmd commands) in Windows 7 that does what connectifyme does. Also you could just create an ad-hoc network.
Windows 7 has an excellent in-built utility, Wireless Hosted Network (Virtual Wifi) technology, that makes your computer, a wireless access point and you can connect all your network devices by sharing a single internet connection thorough your computer or laptop.
Here’s how to set it up.
1. Open command prompt with Administrator privileges. (You can do it by going to start menu, right clicking on command prompt and selecting “Run as administratorâ€).
2. Enter the following command:
Code:
netsh wlan set hostednetwork mode=allow ssid=Test key=Passkey
(This will create a wireless access-point with SSID of “Testâ€
Windows-7-Wifi-Setup
3. Open the Networks and Sharing Center
4. Select your mode of connecting to the internet (ethernet, wi-fi, cable etc.)
5. Enable sharing and select special ‘hosted’ interface or Wireless Connection (i.e. Virtual Wifi miniport)
6. Start it
Code:
netsh wlan start hostednetwork
And you are done.

The problems that you are facing while using connectifyme might be solved if you use this above procedure.However your adapter should support 'hosted networks'. To check for that write the following command in cmd
This will show whether your adapter supports hosted network mode.
