Edimax (7392:c711) Wifi 适配器 - Ubuntu 16.04 LTS 所需的驱动程序

Edimax (7392:c711) Wifi 适配器 - Ubuntu 16.04 LTS 所需的驱动程序

我在查找驱动程序时遇到问题Devolo Wifi Stick ac,它显示为Edimax Technology Co., Ltd(Vendor-ID: 7392) 和 Device-ID c711。当我插入 Stick 时,它会显示Mediatek在我的系统日志中。

我搜索了很多论坛,测试了很多驱动程序,甚至尝试使用带有 ndiswrapper 的 Windows 10 驱动程序。我之前在 Windows 10 上使用过这款棒,它运行正常,除了当我尝试更改无线网络时 -> 我必须重新启动我的笔记本电脑。在我看来,这似乎是电源问题,但我不确定。目前我的笔记本电脑连接到内置无线网卡(Broadcom),这对我来说太慢了。

在我找不到此 Stick 的任何 Linux 驱动程序后,我尝试做的第一件事是使用 ndiswrapper/ndisgtk 并从我的 Windows 10 安装中获取所有需要的文件。设备管理器列出了以下文件:

  • Drivernode 的强名称: oem56.inf
  • INF 部分: OS61_RTWLANSE.ndi
  • INF 名称: oem56.inf
  • 包含的 INF 文件: netvwifibus.inf
  • 服务: netr28ux
  • 驱动程序文件: FW_7662.bin,,,,,,netr28ux.sysPatch_7662.binviwifibus.sysRaCoInst.datRaCoInstx.dll

经过一番研究,我发现联发科收购了 RaLink,这解释了为什么我在RT2870.inf从俄罗斯网站下载的驱动程序文件夹中找到一些困难。此文件夹中包含的文件为(USB_wifi_ WinXP_Vista_7x64.zip):

  • FW_7662.bin
  • netr28ux.cat
  • netr28ux.inf
  • netr28ux.sys
  • Patch_7662.bin
  • RaCoInst.dat
  • RaCoInstx.dll
  • rt2870.cat
  • RT2870.inf
  • RT2870.sys

那么,这款主板可能使用的是 RaLink 芯片组吗?我不知道,因为没有更多信息。即使是手册或供应商主页也没有告诉我它使用的是什么芯片组。因此,如果我使用上述驱动程序和 ndiswrapper,我的系统日志中会出现以下错误:

loadndisdriver: loadndisdriver: load_driver(364): couldn't load driver rt2870

我在 MediaTek-Download-Section 中找不到此驱动程序,文件已于 2016 年 5 月 12 日修改,此驱动程序对我来说最有希望,因为与我的 Windows 10 驱动程序相比,它显示的 ndiswrapper 错误更少,与 相比也更少netr28ux.inf,后者也是存档的一部分,我从上述俄罗斯网站获得。我还找到了一个包含一些 Windows XP 驱动程序的线程,但它对我来说也不起作用。我希望有人能帮助我,我没有主意了。

据我所知,这款 Wifi-Stick 限制在 5 GHz,支持高达 433 MBit/s 的速度,看起来像并且有一个蓝色的 LED,通电/连接时会亮起。我只能通过日志文件或获取有关此棒的信息lsusb
