我买了一台新的华硕 n550jv 笔记本电脑，里面有一块英特尔 AC 7620 无线网卡。我在上面安装了 Arch Linux，发现我会连接到公司的 wifi，但偶尔我会失去所有的互联网连接，但我的 wifi 连接显示一切正常。经过足够多次的连接和重启后，有时它似乎可以正常工作。昨天我让它随机运行了将近 4 个小时。我尝试访问 linux-wireless 并下载我可以使用的最新 iwlwifi 驱动程序，版本 22.24.8.0。似乎没有帮助。也尝试了解决方案使用英特尔双频无线 AC 7260 更新 14.04 后无法再连接互联网但效果并不好。我尝试使用不同的发行版来修复这个问题，但都徒劳无功：Arch Linux、Linux Mint 17、Ubuntu 14.04、Ubuntu 12.10 和其他新的 Ubuntu 变体。

其他人有这个问题吗？我已经尝试解决这个问题近 2 个月了。
答案1
好吧，它并没有完美地解决所有问题。但是添加
options iwlwifi 11n_disable=1 bt_coex_active=0
到 /etc/modprobe.d 文件 (您可以随意命名) 尽管我认为我已经尝试过一次了。
