I'm sure that my wifi button on my laptop is on. I was thinking about some physical damage, but I haven't moved my laptop this night, and in the morning it just doesn't work.
我确定我的笔记本电脑上的 wifi 按钮已打开。我正在考虑一些物理损坏，但今晚我没有移动我的笔记本电脑，早上它就无法工作。
// Bluetooth is not hard blocked, wireless is, but I think it's the same hw button.
// 蓝牙不是硬封锁，无线是，但我认为它是相同的硬件按钮。
I restarted BIOS, and it didn't work, what else can I do, any ideas?
我重新启动了BIOS，但它不起作用，我还能做什么，有什么想法吗？

It's a known fedora bug, workaround is to turn laptop off, switch wifi button off, turn fedora on and swith wifi button on.
这是一个已知的 Fedora 错误，解决方法是关闭笔记本电脑，关闭 wifi 按钮，打开 Fedora 并打开 wifi 按钮。
Note: some laptops (netbooks) may not have a physical wifi switch and instead rely on a Fn key combination. In this case the solution would be to boot into BIOS and enable wifi in those settings.
注意：某些笔记本电脑（上网本）可能没有物理 wifi 开关，而是依靠 Fn 组合键。在这种情况下，解决方案是启动进入 BIOS 并在这些设置中启用 wifi。
