Software access point

Many wireless devices even support simultaneous operation both as AP and as wireless "client" at the same time. Using that capability you can create a software AP acting as a "wireless repeater" for an existing network, using a single wireless device.

Wut?

deactivate first?:

ip link set dev wlan0mon down

rename the interface:

ip link set dev wlan0mon name wlan0

switch interface mode:

iwconfig wlan0 mode managed

re-activate?

ip link set dev wlan0 up
