[Bluetooth](https://www.bluetooth.com/) is a short-range technology for wireless data transfer.
From a [hardware](/wiki/hardware_%28general%29.md) perspective Bluetooth requires a compatible
adapter to work which may be integrated or external.
For [Linux](/wiki/linux.md) based operating systems the
[bluez package](/wiki/linux/bluez.md) is used as the implementation of the
bluetooth standard.
Informations on Bluetooth usage on [Linux](/wiki/linux.md)-based operating systems are described in
the [Bluetooth section of the Linux hardware entry](/wiki/linux/hardware_%28linux%29.md#bluetooth).

# Wi-Fi
Wi-Fi is a type of wireless network protocol that is used for local area networks.
On [Linux-based systems](/wiki/linux.md) there are different programs that handle the Wi-Fi
connection.
- [WPA Supplicant](/wiki/linux/wpa_supplicant.md) is used for WPA2 and WPA3 connections among
others.
- [NetworkManager](/wiki/linux/networkmanager.md) is used for various network connections.
## Usage
Tipps for usage can be found under the corresponding entries.
## Troubleshooting
Tipps for troubleshooting can be found under the corresponding entries, but the ones that use
multiple programs to fix are listed here.
### Restart WPA Supplicant and Reenable the Wi-Fi device
A simple fix for many problems is a restart of [WPA Supplicant](/wiki/linux/wpa_supplicant.md)
aswell as reenabling the Wi-Fi device using [NetworkManager](/wiki/linux/networkmanager.md).
This can be done by first restarting WPA Supplicant as explained in the
[corresponding section](/wiki/linux/wpa_supplicant.md#restarting-wpa-supplicant) and then
reenabling the Wi-Fi device as explained in the
[section of NetworkManagers entry](/wiki/linux/networkmanager.md#restarting-and-reenabling-wi-fi).

# Wi-Fi (General)
Wi-Fi is a wireless networking technology used for wireless local area networks also called WLAN.
It allows devices to communicate over radio frequencies without physical cables.
It needs a module or adapter and therefore relies on dedicated
[hardware](/wiki/hardware_%28general%29.md).
Informations on Wi-Fi usage on [Linux](/wiki/linux.md)-based operating systems are described in
the [Wi-Fi section of the Linux hardware entry](/wiki/linux/hardware_%28linux%29.md#wi-fi).
