Mehrere Wifi-Verbindungen konfigurieren (Raspbian)

/etc/wpa_supplicant/wpa_supplicant.conf

In der Datei

sudo vi /etc/wpa_supplicant/wpa_supplicant.conf

für jede Wifi-Verbindung einen network-Eintrag hinzufügen:

country=AT
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
ap_scan=1

update_config=1

network={
        ssid="SSID-ROUTER-1"
        psk="password1"
}

network={
        ssid="SSID-ROUTER-2"
        psk="password2"
}

/etc/dhcpcd.conf

In der Datei

sudo vi /etc/dhcpcd.conf

nach folgenden Muster statische IP-Adressen konfigurieren:

interface <Network> 
arping <IP_Router1> 
arping <IP_Router2>profile <IP_Router1>

static ip_address=<IP_Pi1>/24 
static routers=<IP_Router1>
static domain_name_servers=<Name_Server1>profile <IP_Router2>

static ip_address=<IP_Pi2>/24 
static routers=<IP_Router2>
static domain_name_servers=<Name_Server2>

Beispiel-Konfiguration:

interface wlan0
arping 10.0.0.1
arping 10.3.0.1

profile 10.0.0.1
static ip_address=10.0.0.180/24
static routers=10.0.0.1
static domain_name_servers=8.8.8.8 8.8.4.4

profile 10.3.0.1
static ip_address=10.3.0.180/24
static routers=10.3.0.1
static domain_name_servers=8.8.8.8 8.8.4.4
