所有网络接口都消失了

我有 3 个以太网接口和一个 WiFi 卡，之前一切都运行良好，直到有一天当我打开它时，它无法调出网络接口。当我运行 ifconfig -a 时，出现的只是我的环回和桥接。上次关闭之前我没有更新任何软件。所有推荐的检查都只出现了桥接和环回，我想知道如何解决这个问题。我正在使用 Ubuntu 16.04.4 服务器。

cat /etc/network/interfaces 输出以下内容：

# Loopback 
auto lo 
iface lo inet loopback  
# WAN interface 
auto enp10s0 
iface enp10s0 inet dhcp  
#Bridge (LAN) 
auto br0 
iface br0 inet static
    address 10.1.10.1
    network 10.1.10.0
    netmask 255.255.255.0
    broadcast 10.1.10.255
    bridge_ports enp8s0
    post-up /usr/sbin/hostapd \
       -P /var/run/hostapd.$IFACE.pid \
       -B /etc/hostapd/hostapd-simple.conf
   pre-down cat /var/run/hostapd.$IFACE.pid | xargs kill

lshw -C 网络的输出：
