四天前安装了 Ubuntu，从那时起就一直在为这个问题而苦苦挣扎。尝试了以下方法与 Intel Centrino Advanced-N 6230 的无线连接不可靠
sudo tee /etc/modprobe.d/iwlwifi-opt.conf <<< "options iwlwifi 11n_disable=1"
重启后不起作用所以恢复。
也尝试过https://ubuntuforums.org/showthread.php?t=2214075并下载了固件并按照链接答案中的步骤进行操作，但没有起作用。
这个答案“askubuntu.com/questions/768843/wifi-problem-on-ubuntu-16-04?noredirect=1&lq=1”
建议从下载最新的上游内核，但我不确定要下载哪个包。
