WiFi 不适用于 Compaq CQ58 (RALINK RT5390R)

WiFi 不适用于 Compaq CQ58 (RALINK RT5390R)

在浏览了所有的论坛寻找答案和帮助之后,在我大约 2012 年的康柏 CQ58(没有成功),我来这里是想向你寻求帮助。

几天来,我安装了多个版本的 Ubuntu 和 Lubuntu,试图让 WiFi 正常工作,但都失败了。目前,我安装了 Lubuntu 18.04 LTS (系统要求) 而且它在这里也不起作用。

我将简要解释一下这个问题:当我打开电脑时,WiFi 连接上了,一分钟内页面加载,一切都进行得非常快,但一分钟后(甚至更短),尽管连接上了,尽管我的手机上有互联网;电脑上却不再工作了。页面无法加载,WiFi 往往会断开连接并更改网络而无法建立连接,不再允许我浏览。

我以为是驱动程序的问题,然后我寻找我的 WiFi 模块(Ralink RT5390R 802.11bgn PCIe)的驱动程序,但我发现它们无法在 Linux 上加载...我只找到了适用于 Windows 的驱动程序,而且我找到的所有代码都没有结果,经常出现 PL 代码错误和其他问题。

你能帮助我吗?我不知道该怎么办。如果你需要详细信息,请告诉我...我正在添加一些输出:

我尝试设置静态 IP 地址,但没有变化。

也许你可以在这里找到解决方案:

安装 Ubuntu 20.04 后,WiFi 卡 Ralink RT3090 看不到任何 WiFi 网络

似乎此 WiFi 芯片组的内核模块可用但未在 Ubuntu 20.04 中加载。使用以下命令加载它并将其设置为在启动时加载:

echo "options rt2800pci  nohwcrypt=1" | sudo tee /etc/modprobe.d/rt2800pci.conf
sudo modprobe -rfv rt2800pci
sudo modprobe -v rt2800pci

我有一台运行 Ubuntu 20.04 的 ASUS X45C(Ralink corp. RT5390),看来它对我来说很有用。

我可能也遇到了同样的问题。我有:

02:00.0 Network controller: Ralink corp. RT5390 [802.11 b/g/n 1T1R G-band PCI Express Single Chip]
    Subsystem: Hewlett-Packard Company Pavilion DM1Z-3000 PCIe wireless card
    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at d0100000 (32-bit, non-prefetchable) [size=64K]
    Capabilities: [40] Power Management version 3
    Capabilities: [50] MSI: Enable- Count=1/32 Maskable- 64bit+
    Capabilities: [70] Express Endpoint, MSI 00
    Capabilities: [100] Advanced Error Reporting
    Capabilities: [140] Device Serial Number 00-00-9e-c4-b7-f9-55-ec
    Kernel driver in use: rt2800pci
    Kernel modules: rt2800pci

使用 linux-image-5.3.0-51-generic 时,它不起作用。它总是断开连接。使用 linux-image-5.3.0-28-generic 时,它工作正常。也适用于我测试过的所有 ubuntu 内核,包括 ubuntu 11.04 内核。

在系统日志中获取此信息:

答案3

我查看了你当前的内核驱动程序,发现此驾驶员信息页面对于它,它似乎列出了您的设备被支持。

建议使用以下命令进行更新(如果您还没有尝试过)。

# apt-get update && apt-get install firmware-ralink

rt2800pci 内核驱动程序的页面还说你应该“根据需要配置你的无线接口”,使用如何使用 WiFi 接口作为指导。

根据您的设备问题,我建议您查看康曼软件包在操作指南中讨论过。看来 connman 可用于自动重新连接断开的连接。
