static IP and using wireless connection to internet

Question

I intend to setup static IP for my raspberry using jessie ver 8. I intend have a static IP to remote my computer to Rpi using VNC through a Ethernet cable so I can see my Rpi screen for this simple purpose, and the other plan is another static IP to connect wirelessly over a network which has a internet access(in short I like the Rpi has internet access). I understand this question had asked few times so I tried to gathered the past info and follow, but still I couldn't get the wireless connection to connect properly which mean it having trouble connecting to internet but it has no problem connect to local network when I tried to ping a local computer in the same network.

/etc/dhcpcd.conf

Is there something wrong written that why it isn't connecting to internet? Appreciate your help and thank you!

Answer 1

I think I figured it out but it work. I should leave the static routers and static domain_name_servers parameter blank, it automatically configure it.
