Questions tagged [hostapd]

For questions on the creation and administration of wireless access points and networks using the user-space daemon hostapd.

hostapd is a user-space daemon that allows the creation of wireless (Wi-Fi) access points on UNIX-like systems. It provides a framework that allows client devices to connect and authenticate, forming a wireless local area network (WLAN). This WLAN may then be bridged to other networks, e.g. to provide wireless internet access.

A multitude of protocols within the IEEE 802.11 standard are supported by hostapd, along with a range of personal and enterprise authentication methods.

Read more about wireless access points on Wikipedia.
