我在戴尔 Inspiron N7010 上运行 Kubuntu 15.10，在最近升级之前，无线连接从未出现过任何问题。连接编辑器未列出任何可用的本地连接。运行sudo lshw -class network返回此

我注意到我的无线设备已从 wlan0 重命名为 wlp4s0。运行sudo iw dev wlp4s0 scan将返回所有可用的无线网络
现在，我可以通过编辑 /etc/network/interfaces 来连接到网络，目前它看起来像这样
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
auto enp5s0
iface enp5s0 inet dhcp
auto wlp4s0
iface wlp4s0 inet dhcp
wpa-ssid myNetwork
wpa-psk myPassword
但每次我都必须编辑它来添加新的连接。
如果我单击系统托盘中网络连接小部件中的刷新按钮，我会收到警报“请求扫描失败 - 不可用时扫描或扫描”
