我最近买了一台新笔记本电脑，里面有一块 Intel 7260AC 无线网卡。我经常遇到无线断线的情况，而且断线的时间间隔不定。据我所知，这种情况只发生在我家。
我尝试过的事情
- 更新到最新主线内核（3.15）
- 更新到英特尔网站上的新驱动程序（将 iwlwifi-7260-8.ucode 复制到 /lib/firmware 并重新启动）。
- 关闭电源管理
- 将家庭无线网络切换为 WEP
我不知该做什么。这对我来说简直是一场灾难。
以下是各种日志的输出

“iwlwifi-7260-7.ucode” 是否可能与“iwlwifi-7260-8.ucode”冲突？我应该删除它吗？还有什么问题？如果我的全新笔记本电脑是家里唯一受此影响的设备，我简直不敢相信这是我的路由器。
