Dell Inspiron 15 3000 系列笔记本电脑新安装时出现“网络已禁用”

在全新安装 Ubuntu 后，WiFi 无法使用...我发布以下内容是因为我看到有人在另一篇文章中询问他们，但我不知道他们的意思... :)

该 Wi-Fi 已被 屏蔽dell_rbtn。您需要将其列入黑名单。

在终端中运行

sudo tee /etc/modprobe.d/blacklist-rbtn.conf <<< "blacklist dell_rbtn"
sudo modprobe -r dell_rbtn && sudo rfkill unblock all

Wi-Fi 应该可以工作。
