I get a tutorial to create a fix ip address for my computer so everytime i connect to the router, my devices ip will remain the same. So this the link that Yee Siang provide to me .
It just some simple step. So first you connect your computer with your router with cable or wifi then open a browser key in 192.168.0.1 to got the router setting. If this is your first time login the user name and password should be admin.
After login you will see this page .
Then go to DHCP and the left navi bar there .
but before that got copy MAC address. To find it go to DHCP Client List . Inside there got the list of devices that are connected to the router.
After that create new Address reservation page then you will see this page
Key in your MAC address the create an ip address for it . For this project i set my computer ip address to 192.168.0.103. Make sure you Enabled the status.
When save then this will show up.
Refresh your router and the page then go to DHCP> Client List then you will see you computer ip address become permanent.
