# Setting up Wi-Fi
2021-10-19 07:05:26 +00:00
The following describes how to setup a Wi-Fi connection on the default pikvm builds based on Arch Linux.
The process might vary for other Linux distros. We recommend to do this while having a display and keyboard
connected directly to the Raspberry Pi as you will loose network connectivity once you connect to a Wi-Fi.
Alternatively you can connect to the PiKVM via SSH. The built-in Web Terminal (available through the browser) should also work.

Please review [First Steps ](first_steps.md ) if you are setting up wifi for the zero2w. This guide also applies to Wi-Fi setup for v2+ devices if switching from Ethernet to Wi-Fi..

There is nothing more reliable than wired Ethernet, so it's better to use it. Wi-Fi with the steel case (on V3) results in poor performance. But who are we to stop you... :)

!!! note "[ADVANCED USERS ONLY] Moving Wi-Fi settings for OS older than 2021.10.19"
2021-10-19 07:05:26 +00:00
Starting from 2021.10.19, the old way to configure Wi-Fi using `netctl` is deprecated.
Instead, it is proposed to use a more native path with `systemd-networkd` , which is already used to configure Ethernet.
Follow the guide and then delete the old netctl profile:
```
# rw
# systemctl disable netctl-auto@wlan0.service
# rm /etc/netctl/wlan0-*
# ro
```

1. Make filesystem writable using `rw` command.
2021-10-19 05:00:53 +00:00
2. Create Wi-Fi settings file `/etc/systemd/network/wlan0.network` with following content:
2021-10-12 18:45:00 +00:00
2021-10-19 05:00:53 +00:00
```ini
[Match]
2021-10-19 05:13:29 +00:00
Name=wlan0
2021-10-12 18:45:00 +00:00
2021-10-19 05:00:53 +00:00
[Network]
DHCP=yes
DNSSEC=no
2021-10-12 18:45:00 +00:00
2021-10-19 05:00:53 +00:00
# Use same IP by forcing to use MAC address for clientID
[DHCP]
ClientIdentifier=mac
2021-10-12 18:45:00 +00:00
```
2021-10-19 05:00:53 +00:00
3. Set network ESSID and password:
2021-10-12 18:45:00 +00:00
```
2021-12-07 02:57:39 +00:00
# wpa_passphrase MyNetwork 'P@assw0rd' > /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
2021-10-12 18:45:00 +00:00
```
2021-12-07 02:57:39 +00:00
2021-10-19 05:00:53 +00:00
!!! note "Using Wi-Fi with hidden ESSID"
Add option `scan_ssid=1` to `/etc/wpa_supplicant/wpa_supplicant-wlan0.conf`
!!! note "Using 5GHz Wi-Fi in the USA"
Add option `country=US` to `/etc/wpa_supplicant/wpa_supplicant-wlan0.conf`
2021-12-07 02:58:36 +00:00
2021-10-19 05:00:53 +00:00
4. Enable WPA-supplicant service:
```
2021-10-19 05:13:29 +00:00
systemctl enable wpa_supplicant@wlan0.service
2021-10-19 05:00:53 +00:00
```
5. Make filesystem read-only again using `ro` command

## Useful console commands
* `iwconfig` - Manipulate the basic wireless parameters.
* `iwlist` - Allow's you to initiate scanning and list frequencies, bit-rates, encryption keys, etc.
* `iwspy` - Displays per node link quality.
* `iwpriv` - Allow's you to manipulate the Wireless Extensions specific to a driver (private).

# iw dev wlan0 scan | egrep "signal:|SSID:" | sed -e "s/\tsignal: //" -e "s/\tSSID: //" | awk '{ORS = (NR % 2 == 0)? "\n" : " "; print}' | sort
```
```
# iwlist wlan0 scan | egrep "Cell|ESSID|Signal|Rates"
