I have a Windows 7 laptop and a Ubuntu laptop, and I would like to share my internet from the Ethernet port over wifi. If I have my Windows 7 laptop connected to the Ethernet connection I can join an ad-hoc wifi network with my Ubuntu laptop and use the internet on it. If I connect the Ubuntu laptop to the Ethernet connection and create an ad-hoc network, my Windows 7 laptop can join it but can't connect to the internet.

The card in the Ubuntu pc is a Intel PRO/Wireless 2200BG and it supports these interface modes:

  • IBBS (this is ad-hoc and all I should need from what I understand)
  • Managed
