双启动 Windows Ubuntu Internet 无法连接到服务器

双启动 Windows Ubuntu Internet 无法连接到服务器

我在 Ubuntu 16.04 之后安装了 Windows 10 试用版,Ubuntu 的 wifi 和以太网停止工作。我的 Ubuntu 曾经出现过一些 wifi 连接问题(速度慢或无法连接,这在所有 Ubuntu 系统上都会发生,所以这是另一个问题。),但以太网通常可以正常工作。Windows 10 的以太网或 wifi 工作正常。我怀疑存在驱动程序冲突,但我不知道该怎么办。

这个答案这里建议一个以太网解决方案,但我找不到针对 wifi 连接的类似解决方案。

Ubuntu 也因得不到大多数 wifi 芯片组制造商的良好支持而闻名,因此我尝试了三个 wifi 适配器 rtl8192cu、TL-WN722N_V3(rtl8188eu) 和 TP-Link TL-WR710N (Atheros AR9331)。网络管理器显示它们都可以检测到来自不同路由器的 wifi 信号,但当我使用浏览器或 ping 命令时,它们无法连接到互联网。

我可以连接到路由器192.168.1.1。

我无法连接到https://tplinklogin.net,或192.168.1.254,这是用于设置wifi适配器TL-WR710N的管理页面。

我无法通过 USB 网络共享或 Wi-Fi 热点将手机数据计划连接到互联网。

您应该更新您的内核版本或尝试找到兼容的版本。

一般来说,在当前发行版上运行升级应该会安装更新的内核,理想情况下可以解决你的问题

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

如果此后您仍然遇到驱动程序问题,那么您必须手动进行内核降级来解决您的问题。

尝试一下这个指南:

或者,如果您想使用终端风格,请使用本指南获取稳定的内核版本并进行相应更新。

最新的稳定内核是什么以及如何安装它?

编辑:根据您的评论,您可以尝试使用 dhclient 强制配置例如,使用 wlx503eaa705446 适配器

sudo dhclient wlx503eaa705446 

这应该强制进行网络配置以进行正确的 DNS 解析。
