我嘗試了不同的修復程序,經過一些谷歌搜尋後發現(這和這),但它們都不起作用。有人可以幫我辨識並解決這個問題嗎?
編輯:
modinfo ath10k_pci | grep backport
version: backported from Linux (next-20151120-0-ga78de01) using backports backports-20151120-0-g906a6b3
答案1
您已經安裝了向後移植,但在 16.04 中不需要它們,因此我們需要卸載
cd backports-20151120
sudo make uninstall
如果韌體已安裝,則重新啟動和 wifi 應該可以工作
沒有多少人擁有多個版本的向後移植,因此您可以使用終端機中內建的自動完成功能,cd backports
然後按 TAB 鍵,它應該會為您完成命令。然後在 backports 目錄中執行sudo make uninstall
卸載 backports 並重新啟動
答案2
以防萬一有類似情況的人:
更新至4.8內核
sudo apt-get update && sudo apt-get install linux-generic-hwe-16.04
然後重新啟動。
