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。

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。
