Xenial 中的 Realtek RTL8188EE 驅動程式？

我剛剛更新了預安全啟動、預 UEFI* Toshiba2012衛星P755-S5390筆記型電腦從 15.10 到 16.04。在15.10中，無線適配器運作正常。現在，Ubuntu 拒絕承認我的筆記型電腦有無線介面。我已重新啟動多次，執行以下操作：

apt install flashrom librtlsdr* nictools* r8168-dkms rtl-sdr rtl8812*

這似乎很成功，而我在網路上找到的許多其他東西都無濟於事。Additional Drivers的螢幕有Software and Updates一個條目，它聲稱該條目是unknown或not working correctly。

在此輸入影像描述

Network Settings是一個簡短的條目（在左側，曾經有一個“Wifi”設備左右）：

阿斯達斯德

（在你問之前，不，小加號沒有幫助。）

我發現這個帖子用戶遇到類似的問題，並且他們發布了來自大量命令的大量數據，因此我將在這裡執行相同的操作。

如何找回我的wlp2s0/wlan0無線介面？

那是eth0實體乙太網路設備。我的無線卡在以下位置引用/var/syslog：

$ cat /var/log/syslog | grep -e wlan0

好吧，那是更新之前的事，但確實如此。

正如這裡建議的：如何讓 Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01) 無線網卡在 Debian Wheezy 上運作

$ locate rtl8188ee | grep -v "debug" | grep .ko

insmod /lib/modules/4.2.0-36-generic/kernel/drivers/net/wireless/rtlwifi/rtl8188ee/rtl8188ee.ko

但重啟後wifi適配器仍然無法運作。

*我的筆記型電腦從來沒有 UEFI，仍然只有 BIOS；結果我的問題不一樣Realtek 驅動程式 RTL8723BE 在 Ubuntu 16.04（核心 4.4）中無法運作。

答案1

我不知道你是否已經看過這篇文章，但這裡是。關聯

根據該問題的答案，似乎有一個更好的驅動程式可以由在 GitHub 中維護的第三方開發人員提供。

因此，打開終端機 (Ctrl+Alt+T) 並按照以下步驟操作：

sudo apt-get install build-essential linux-headers-generic git dkms
git clone http://github.com/lwfinger/rtlwifi_new.git
cd /path/to/rtlwifi_new
make
sudo modprobe -rv rtl8188ee
sudo make install
sudo modprobe -v rtl8188ee

希望這可以幫助 ：）

答案2

因此，如果您沒有驅動程序，關於從原始程式碼安裝驅動程式的另一個答案絕對是正確的。

就我而言，我所要做的就是

  • 拆開我的筆記型電腦以確保無線適配器正常實際上連接的
  • 把它放回原處
  • 重啟幾次
  • 空閒地切換啟用無線區域網BIOS 中設定為離開*
  • ???
  • 我現在有無線網路了。

*是的，這可能是個錯誤。希望這對其他 Satellite P755 用戶有所幫助。
