我想在我刚买的Gigabyte mini-ITX系统上使用内置WiFi作为接入点。出于某种原因，我要进入圈子。
lspci | grep -i wireless显示：
04:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)
lsmod | grep 80211给出：
mac80211 630669 1 iwlmvm
cfg80211 484040 3 iwlwifi,mac80211,iwlmvm
我安装了 hostapd 。这是我创建的（超过）最小hostapd.conf：

wmm_ac_vo_cwmin=2
wmm_ac_vo_cwmax=3
wmm_ac_vo_txop_limit=47
own_ip_addr=127.0.0.1
当我尝试运行hostapd时，我明白了：
$ 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，我读到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，现在看来驱动程序（2.1版）会出现错误，并且在忽略它之前。
解决方案（在桌面情况下）是要执行以下操作来释放资源..然后hostapd没有错误....
sudo nmcli nm wifi off
sudo rfkill unblock wlan
此信息已从https://bbs.archlinux.org/viewtopic.php?pid=1221799
收集nmcli是网络管理员的一部分，需要安装。 接着，
/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，这可能是一种解决方法。
/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建议：
sudo ifconfig wlan0 10.15.0.1/24 up
sleep 1
sudo service isc-dhcp-server restart
sudo service hostapd restart
尚未安装isc-dhcp-server。其他所有内容都没有显示任何错误。
虽然仍有问题！

使用iwconfig将其设置为＆＃34; Master＆＃34;模式，我认为这意味着将其设置为AP模式，结果如下：
$ sudo iwconfig wlan0 mode Master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
所以，我猜可能7260驱动程序不想在AP模式下工作。但是，iwlist命令输出将AP模式显示为其中一种可能性。
