几年前，我使用带有迷你 PCIe 的 fitlet i“准系统”迷你电脑组装了一个 DIY 路由器英特尔 7260wifi 卡（使用 iwlwifi 驱动程序）以 AP 模式运行（桥接到来自我的电缆调制解调器的以太网）。许多黑客手段可以使其运行，包括 WPA 请求者、hostapd 等。
不幸的是，即使经过大量的反复试验才让这张卡工作，我还是无法让它以高于 54mbps 的速度运行，尽管它说这是一张 5ghz 的“双频”卡（似乎 5ghz AC 仅在客户端模式下受支持，并且它只有一个无线电）。这对于慢速 100mbps 有线互联网来说工作正常。
但我最近发现我所在社区现在提供对称千兆互联网，并已注册。
在 Ubuntu 上支持更快的 mini PCIe wifi AP 适配器有哪些选择？有这样的事吗？即使 100mbps 也很好，但千兆 wifi 就太棒了。或者，如果有办法强制我当前卡上的 AP 模式速度更快，我会很高兴。
