Edimax (7392:c711) Wifi 適配器 - Linux Mint 18 所需的驅動程序

  • October 11, 2016

我在查找我的驅動程序時遇到問題Devolo Wifi Stick ac,它顯示為Edimax Technology Co., Ltd(Vendor-ID: 7392) 和 Device-ID c711。當我插入 Stick 時,它會顯示Mediatek在我的系統日誌中。

我搜尋了很多論壇,測試了很多驅動程序,甚至嘗試使用帶有 ndiswrapper 的 Windows 10 驅動程序。我之前在 Windows 10 上使用過這個 Stick,它工作時沒有 oa 問題,除非我嘗試更改無線網路 -> 我不得不重新啟動我的筆記型電腦。在我看來,這就像一個電源問題,但我不確定。目前我的筆記本連接了內置的無線網卡(Broadcom),這對我的需要來說太慢了。

在我沒有為這個 Stick 找到任何 Linux 驅動程序後,我嘗試的第一件事是使用 ndiswrapper/ndisgtk 並從我的 Windows 10 安裝中獲取所有需要的文件。設備管理器列出了這些文件:

  • Drivernode 的強名稱: oem56.inf
  • INF-部分: OS61_RTWLANSE.ndi
  • INF 名稱: oem56.inf
  • 包含的 INF 文件: netvwifibus.inf
  • 服務: netr28ux
  • 驅動程序文件: FW_7662.bin , netr28ux.sys, Patch_7662.bin, viwifibus.sys, RaCoInst.dat,RaCoInstx.dll

經過一番研究,我發現聯發科收購了 RaLink,並通過這種方式向我解釋了為什麼我在一個RT2870.inf從俄羅斯網站下載時遇到一些困難的驅動程序文件夾中發現了一個內部。此文件夾中包含的文件為 ( 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

那麼,也許這根搖桿使用的是 RaLink 晶片組?我不知道,因為沒有更多關於它的資訊。甚至手冊或供應商首頁也沒有給我任何線索使用什麼晶片組。因此,如果我將上面的驅動程序與 ndiswrapper 一起使用,我的系統日誌中會出現以下錯誤:

usb 3-2: new high-speed USB device number 7 using xhci_hcd

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

我在 MediaTek-Download-Section 中找不到此驅動程序,文件已於 2016 年 5 月 12 日修改,此驅動程序對我來說看起來最有希望,因為與我的 Windows 10 驅動程序相比,它顯示的 ndiswrapper 錯誤更少,而且錯誤更少相比之下netr28ux.inf,這也是檔案的一部分,我是從上述俄羅斯網站獲得的。我還發現了一個帶有一些 Windows XP 驅動程序的執行緒,它對我也不起作用。我希望有人可以幫助我,我沒有想法。

附加資訊在這裡

Afaik 這款 Wifi-Stick 僅限於 5 GHz,支持高達 433 MBit/s 的速度,它看起來像這樣,並且有一個藍色 LED,在通電/連接時應該會亮起。我只能通過日誌文件或lsusb.

作業系統: Linux Mint 18 Sarah 64 位(Ubuntu 16.04 LTS)

wlp2s0b1不是 Wifi-Stick,而是內置的 wifi 卡。(PCI) 從這裡

複製,因為這個問題因為不是“Ubuntu 的官方風格”而被拒絕。(我是這兩個問題的作者)

那麼,也許這根搖桿使用的是 RaLink 晶片組?

根據wikidevi,可能的驅動程序是mt7610u_sta(使用ID:7392:a711獲取必要的資訊),驅動程序可以安裝如下

sudo apt-get install git build-essential
mkdir ~/src
cd ~/src
git clone https://github.com/Myria-de/mt7610u_wifi_sta_v3002_dpo_20130916.git
make
make install
cp RT2870STA.dat  /etc/Wireless/RT2870STA/RT2870STA.dat
reboot
