我在个人笔记本电脑上安装了 Ubuntu，并连接到酒店 wifi，我之前在同一台电脑上使用 Windows。这个网络是标准的酒店 wifi，您需要以客人身份输入凭据才能访问，但它直接连接，没有任何提示，就像绕过了路由器提示一样。
我的问题是它是如何做到的？它是否检测到了我笔记本电脑的 MAC 地址，然后就认为是我？
根据官方文档，Archer T4u 支持 USB 3，但当我将其连接到 USB 3 端口时，它被检测为 USB 2 设备（根据 lsusb 输出）。我在运行 Fedora 40 的 Ubuntu PC 和笔记本电脑上都尝试了此操作，它们都具有较新的 USB 3.1 端口。该设备无需安装任何驱动程序即可运行。
我想将运行 Ubuntu 的笔记本电脑加入 Android WiFi 热点的白名单。执行此操作将返回、、和hostnamectl等信息。以下哪一个是正确的？Static hostnameIcon nameMachine IDBoot ID
wlan0我在终端中执行操作获取了接口的 MAC 地址ip addr，并将其与 一起添加Static hostname到白名单中，但连接失败。信号强度非常好，WPA2 密码正确。
附言：在 Windows 10 机器上，您可以通过hostname在命令行中执行或在“设备名称”下查找来获取相应的名称Settings > System > About。
这里有新的 Linux 用户。我无法在通过 USB 网络共享连接到互联网的 Dell XPS 13 9343 笔记本电脑上找到 wifi。无线网卡 - Broadcom BCM4352 802.11ac 双频 (14e4:43b1) rev 03。我尝试安装 bcmwl-kernel-source 和 firmware-b43-installer，但出现无法找到两个命令的包的错误。
请帮忙！
我的 PC 的 Wifi 最近停止工作了，可能是在内核升级之后。Wifi 连接到 SSID，端口分配了一个 IP 地址。但是，除了主机本身之外，我无法 ping 任何东西。尝试过重新启动、重新连接、重新启动 Wifi 路由器、禁用 GUFW 等，但都不起作用。局域网中的其他一切都运行良好。
尝试添加以下 Grub 启动参数，但没有帮助：
pcie_aspm=off
更改以下参数以禁用省电模式，甚至有帮助 - /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf：
wifi.powersave = 3 ==> 2
将电源管理中的省电模式更改为平衡，问题仍然存在。
Wifi Dongle 是TP-Link Archer T3U [Realtek RTL8812BU]
我怀疑是内核或固件出了问题，或者是硬件出了问题。请指导我找出问题所在，并尽可能帮助解决。
以下是 DMESG 命令和 Wireless-info 脚本的输出：
过去，WiFi密码可以在/etc/NetworkManager/system-connections/.对于新的Ubuntu 24.04 Noble Numbat，该文件夹是空的（即使我现在使用家庭 WiFi 来发布这个问题）。
那么问题来了，WiFi密码现在存储在哪里呢？
PS：我还通过 GUI 建立了活动的 Wireguard VPN 连接NetworkManager。该/etc/NetworkManager/system-connections/VPN文件夹也是空的。
我正在一台配备 Intel wifi7 的笔记本电脑上运行 Ubuntu 22.04.4（与 win11 双启动）。
一切都进行得很好，直到我盲目信任 Ubuntu 软件更新的系统软件更新。更新后电脑仍然有稳定的WiFi连接，我在设置中通过语言和区域安装了中文并进行了zoom会议。但电脑重启后，WiFi只会连接一分钟左右，然后就无法使用，过一段时间后又可以使用。
如果我单击 WiFi 设置，它会显示 NetworkManager 已关闭。所以我尝试了以下方法：
- 将 WiFi 电源管理设置为 2（禁用）
- 重新安装 NetworkManager 并重新启动。两者都不起作用。
dmesg -w以下是网络从工作变为不工作时的输出转储。

先谢谢了！
PS：我认为WiFi硬件工作正常，因为它在win11上运行良好
新手，最近在 Raspberry Pi 4 上安装了 Ubuntu Server OS。它显示网络不受管理，这也可能是当我尝试演讲者和听众演示时，开发机器上的 ROS 无法与 Raspberry Pi 上的 ROS 通信的原因。
我安装了 Ubuntu 22.04.4，但 wifi 选项不可用，笔记本电脑：Asus Vivobook 16X。 https://paste.ubuntu.com/p/zsmVFbhPVn/

最近升级后，注意到 wifi 随机断开，速度在几秒钟内从 0.1Mbps 到 100Mbps 来回变化，可能会上升几秒钟，或者几个小时，无法预测。我正在尝试使用提交错误报告ubuntu-bug，但我不知道哪个包有问题。
这可能是一些相关信息，但我查看了模块，没有看到类似的内容rtw_8821ce，有些rtw88_*模块可能相关，但无论如何，据我所知，我无法将它们映射到任何包。

这是我能找到的最好的参考：WiFi 频繁且随机断开连接， rtw_8821ce driver，但即使它位于“新手角”部分，我也无法遵循他们在做什么。就像“您是否尝试过仅使用 wpa_supplicant（以及 DHCP 客户端，如果需要）进行连接？” 远远超出了我的技能水平。
无论如何，如果有人可以帮助识别相关的包，我至少想填写一份错误报告。
根据要求，这是我刚刚重新启动的相关输出iwconfig，因为这有时会有所帮助，因此统计数据可能不具有代表性：
