debian同时配置无线wifi和有线以太网连接，wifi无法自动连接。

Question

有线连接公司内网，有两个ip。wifi连接外网。现在的问题是，每次系统启动时，有线连接可以正确连接debian同时配置无线wifi和有线以太网连接，wifi无法自动连接。，而wifi却不能连接，需要手动执行ifdown wlp3s0, ifup wlp3s0来连接。

我的配置文件/etc/network/interfaces

# 有线连接：公司内网，两个ip
auto enp2s0 enp2s0:1
iface enp2s0 inet static
address 192.168.186.142
netmask 255.255.255.0
gateway 192.168.186.254
up route add -net 192.168.186.0 netmask 255.255.255.0 gw 192.168.186.254
down route del -host 192.168.100.12 gw 192.168.186.254

iface enp2s0:1 inet static
address 172.22.99.99
netmask 255.255.0.0
gateway 192.168.186.254
up route add -net 172.22.0.0 netmask 255.255.0.0 gw 192.168.186.254
down route add -net 172.22.0.0 netmask 255.255.0.0 gw 192.168.186.254

# 无线连接wifi：外网
auto wlp3s0
iface wlp3s0 inet dhcp
    wpa-ssid xxx
    wpa-psk xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
up route add default gw 192.168.43.1
down route del default gw 192.168.43.1

执行命令 dmesg | grep wlp3s0
