如何使用笔记本电脑的 WiFi 卡设置无线接入点？

Question

想与运行 2.2.1 的 Android（Galaxy Mini）共享我的笔记本电脑（运行 Ubuntu 10.10）宽带。由于 Android 目前不支持 ad-hoc 网络，因此“创建新的无线网络..”将无济于事。

Q1) 我如何使用我的笔记本电脑 WiFi 卡设置无线接入点？Q2）“ad-hoc”网络和“接入点”有什么区别？

Answer 1

并非所有无线卡都支持接入点模式。在您对软件感到沮丧之前，请先检查一下您的卡是否符合要求。

Answer 2

OpenWRT 用于hostapd提供其服务。它适用于乌图图。

您还需要安排伪装和防火墙。我喜欢 Shorewall 之类的东西。在您的情况下，双接口模型应该运行良好。
