Can a Linux machine act as both a wireless client and access point simultaneously using a single physical WLAN interface?
Quick scenario:
Have 2 devices with wifi cards
Only 1 computer can connect to the area wifi network due to security issues.
Is there anyway to make the connected computer simultaneously act as a wifi router and have the other device to connect to the internet through it? Or is it impossible to do that without two cards?
