成功之后是这样的: wlan0在上面

pi@raspberrypi:~ $ ip route show
default via 192.168.77.1 dev wlan0 src 192.168.77.186 metric 200
default via 192.168.9.1 dev eth0 src 192.168.9.98 metric 300
192.168.9.0/24 dev eth0 proto dhcp scope link src 192.168.9.98 metric 300
192.168.77.0/24 dev wlan0 proto dhcp scope link src 192.168.77.186 metric 200
