新入手的树霉派配无线网卡遇到以下问题
pi@RaspberryPi ~ $ sudo ifup wlan0

在查询后在官网论谈找到以下解决方案
也就是说直接修改 /etc/network/interfaces文件为以下内容，注意：NETWORK SSID为要连的网络名，NETWORK PASSWORD为网络密码：
auto lo
iface lo inet loopback
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wpa-ssid “NETWORK SSID”
wpa-psk “NETWORK PASSWORD”

如果WIFI没密码呢？

你可以把密码设为空（即""）试试，我没有试过，你试了以后发一下结果。
