最近做一个项目,需要做一个WIFI连接模块,这几天都在折腾,终于,今天终于是连上网络了,只不过连网的过程有点慢,还有一些缺点,先写下来以备忘记. 1.环境建立: sudo apt-get install wpasupplicant 2.Command: sudo service network-manager stop sudo service wicd stop pkill nm-applet 3.bring our interface up: sudo ip link set wlan0 u…

First, ensure that the computer/sbc has WI-FI parts. install wpa_supplicant, edit /etc/wpa_supplicant/wpa_supplicant.conf, with ssid & psk. Then run wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf & to connect to the named ssid.…

解决办法: 首先要先在后台启动一个 CentOS7 容器(注意不要少参数): docker run -d -e "container=docker" --privileged=true -v /sys/fs/cgroup:/sys/fs/cgroup --name centos7 centos /usr/sbin/init 然后再进入这个容器即可: docker exec -it ab49ca003950 /bin/bash…
