华硕笔记本电脑升级至18.04后未连接

Question

我升级到Ubuntu18.04，现在无法连接到wifi。如果尝试从系统菜单，我看到“连接失败-激活网络连接失败”。有线连接正常。网络适配器是Qualcomm AR9485，但是在“软件和更新-附加驱动程序”中缺少驱动程序。这是无线信息：

Answer 1

我有华硕zenbook和无线工作正常。注意，当您使用ifconfig wlp2sX时，无线接口可以显示为wlanX而不是wlanX。您可以尝试以下几种方法：

1.获取关于可用WiFi网络的详细信息：

$ sudo iwlist wlp2sX扫描

2.将网络添加到已知的wifi网络：

编辑文件/etc/wpa_supplicant/wpa_supplicant.conf：

转到文件的底部并添加以下内容：

network={ ssid="your_ssid“psk="your_password”}

注意！记住引号(")和最后一个结束括号(})。

3.将Wifi接口提升到

上

$ sudo ifdown wlp2sX；sudo ifup wlp2sX

希望这能有所帮助！
