我无法在我的旧东芝 Satellite 笔记本电脑（约 2009 年）上使用 wifi。以太网工作正常，但如果我断开电缆并将计算机连接到 wifi，机器总会在 1-2 分钟后冻结。除此之外，Wifi 似乎工作正常，因为我可以浏览互联网，直到一切都冻结，我不得不重新启动计算机。
我正在运行 Lubuntu（Ubuntu 14.04.5 LTS）。
以下是我的网络规格的链接：
http://paste.ubuntu.com/25469741/
我应该提到我跑了
sudo apt update
sudo apt dist-upgrade
在发布此问题之前。
此外，如果这有用：

我看到 GitHub 上有一个最新的 Realtek rtlwifi 代码库（https://github.com/lwfinger/rtlwifi_new)，但我不确定这是否能解决问题或者如何安装正确的代码。
我是 Linux 新手。感谢您的帮助！
答案1
我通过规避问题解决了这个问题：我得到了一个无线适配器，在这种情况下TP-Link Archer T2U AC600 无线双频 USB 适配器。
我必须安装驱动程序，按照本页底部的说明进行操作：修改了 TP_link TL-WDN5200 的 USB wifi 驱动程序
我想说的是，我在这个页面上的 Chili 555 的回答指引了我朝这个方向前进：Ubuntu 14.04 LTS x64 上的 TP-Link AC600 驱动程序。非常感谢，谢谢。
很高兴这个问题已经解决了！
