我正在使用这台笔记本电脑我一直都很喜欢艺术，直到最近我决定改用 Linux 以获得更好的体验。我安装了 Ubuntu MATE，乍一看，一切似乎都很好。然而，我花了一点时间才意识到安装程序没有要求 Wifi 设置，安装后 Wifi 也无法工作。似乎没有任何 wifi 设置，使用后sudo lshw -C net，我得到了以下结果：
*-usb:0 DISABLED,
description: interface,
product: EC25-AF,
vendor: Quectel,
physical id: 3,
bus info: usb@1:3,
logicalname:wwan0,
version: 3.18,
未检测到 WLAN 设备。即使使用也sudo lspci没有任何结果。甚至没有sudo lsmod。还有其他方法可以找到我的 wifi 卡吗？
编辑：这是完整的输出sudo lspci

昨天 WLAN 适配器没有显示sudo lsusb，我想现在应该可以显示了。有谁知道该适配器的正确驱动程序吗？
（也感谢那些编辑问题的人，我是这个网站的新手）
答案1
对于 Linux 来说，这是一款相当粗糙的笔记本电脑。我个人更喜欢使用戴尔笔记本电脑。是的，你要多花点钱，但我在它们成为顶级产品两年后才购买的，而且是游戏机型。
您的笔记本电脑最引人注目的第一个规格是：
- Microsoft Windows 10 专业教育版
确实，对于销售此类 MS 特殊许可证的零售商应该有某种审查程序。
显然，利润微薄的零售商不会对笔记本电脑进行 Linux 测试，尤其是 Ubuntu 测试。

谢谢你的帮助。我能够使用 lwfinger 的 rtl8723du 驱动程序让它工作。谢谢！
