Configure static ipv4 address

Hi, guys.
I have a youku-yk1c router running LEDE 17.01.4. My ipv4 address is static and the address binds to the mac. I configure the IP address through IPV4. But it seems not work. I can not ping the gateway. The same setting works fine on Openwrt 15.05. No idea what happens.

Please elaborate and post your system log (ensure you remove you WAN IP, DDNS address, and/or MAC Addresses)
