我想使用我刚刚购买的技嘉 mini-ITX 系统上的内置 WiFi 作为接入点。出于某种原因，我一直在兜圈子。

我安装了hostapd。这是我创建的（超过）最小

当我尝试运行 hostapd 时，我得到以下信息：
$ sudo hostapd ./hostapd.conf
Configuration file: ./hostapd.conf
nl80211: Could not configure driver mode
nl80211 driver initialization failed.
hostapd_free_hapd_data: Interface wlan0 wasn't started
所以，我了解到 Ubuntu 14.04 存在问题以及如何解决它。
https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1289047
有趣的是，现在驱动程序（版本 2.1）执行了一些错误操作，而之前它忽略了它。
解决方案（在桌面情况下）是执行以下操作来释放资源..然后hostapd就没有错误....
sudo nmcli nm wifi off
sudo rfkill unblock wlan
此信息是从 https://bbs.archlinux.org/viewtopic.php?pid=1221799
收集的nmcli 是网络管理器的一部分，需要安装。 接下来，
/etc/hostapd$ sudo nmcli nm wifi off
** (process:5724): WARNING **: Could not initialize NMClient /org/freedesktop/NetworkManager: The name org.freedesktop.NetworkManager was not provided by any .service files
所以我运行了这些命令，这应该是一种解决方法。
/etc/hostapd$ sudo service network-manager start
network-manager start/running, process 5763
/etc/hostapd$ sudo nmcli nm wifi off
/etc/hostapd$ sudo rfkill unblock wlan
但是尝试运行 hostapd 仍然存在同样的问题。
https://askubuntu.com/questions/472794/hostapd-error-nl80211-could-not-configure-driver-mode推荐这个：
sudo ifconfig wlan0 10.15.0.1/24 up
sleep 1
sudo service isc-dhcp-server restart
sudo service hostapd restart
isc-dhcp-server 尚未安装。其他一切都运行，没有显示任何错误。
仍然有问题！

使用
iwconfig$ sudo iwconfig wlan0 mode Master
Error for wireless request "Set Mode" (8B06) :

所以，我猜7260驱动程序可能不想在AP模式下工作。但是，
iwlistOP 写道：
好吧，看起来很开心，我只需要添加以下内容：
### Set your bridge name ### bridge=br0到 hostapd.conf 文件。现在我明白了：
