我想将我的Raspberry Pi设置为静态IP设备，它通过以太网进行通信（通过像192.168.20.X这样的IP），同时它应该通过WLAN（192.168.1.1）连接到互联网。但是，当我允许“auto eth0”时，它不会配置 wlan0。我希望他们俩都能工作。我当前的配置如下：
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.20.40
netmask 255.255.255.0
network 192.168.20.1
gateway 192.168.20.1
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
我缺少什么？任何帮助，将不胜感激。提前致谢。
解决了：
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.20.45
netmask 255.255.255.0
network 192.168.20.1
gateway 192.168.1.1 # Changing this worked
dns-nameservers 8.8.8.8 8.8.4.4
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

我有类似的配置：静态 ip oneth0和动态 ip on wlan0。
/etc/network/interfaces这是我的文件的内容：
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
我配置 dhcp 或静态地址的位置位于/etc/dhcpcd.conf
interface eth0
static ip_address=192.168.20.40
static routers=192.168.20.1
nogateway
interface wlan0
static routers=192.168.1.1
static domain_name_servers=8.8.8.8 8.8.4.4
（我根据您的配置调整了该文件）
您还必须配置 Wifi（SSID、密码等）/etc/wpa_supplicant/wpa_supplicant.conf（我想您已经这样做了）
笔记：我正在使用树莓派杰西。我认为在以前的版本中（喘息）网络配置是不同的
编辑：添加了DNS配置
