[已解决] [重复] 我是 Ubuntu 15.04 生动的 64 位用户，自从 15.04 以来我的 wifi 出现了这么多问题，真无聊 :( 连接不稳定，丢包，自动挂起后丢失连接等...在启动时，WiFi 似乎正确，但经过一段时间（不规则）它就消失了。通常，状态栏会告诉我“Wifi 未准备好”或“wifi 已停用”（没有物理按钮......）
请提供一些帮助，以下是一些信息：
lspci -k -nn | grep -A 3 -i net

我已将 ideapad_laptop 列入黑名单/etc/modprobe.d/blacklist.conf
我没有，/etc/modprobe.d/iwlmvm.conf因为我想使用 Wifi 11N...
我正在使用/lib/firmware/iwlwifi-7260-13.ucode（欺骗操作系统将其重命名为 .10）
