Ubuntu 14.04/核心升級4.0無無線

有人知道升級到核心4.0後除了降級之外修復TP-Link Tl821N無線連接的任何解決方案嗎？沒有有關無線適配器的資訊。

kde中的網路圖示是紅色叉的，連接選單上沒有出現wifi連接，無法連接到網路。

同時，試著看看以下是否有效https://github.com/OpenELEC/OpenELEC.tv/blob/master/packages/linux-drivers/RTL8192CU/patches/RTL8192CU-kernel-4.0.patch

答案1

答案非常明確：所有 4.x 核心線都有問題。這就是解決方案，重新安裝 3.19x 核心線以恢復 WIFI，因為暫時沒有官方解決問題： https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1424676 此線程中可能有一個可選的解決方案： 如何編譯bcmwl-ubuntu？

答案2

找到並安裝網路驅動程序，更新的核心不提供正確的驅動程式
