Assign IP address manually

If you haven’t set up anything and left everything as default, you can try to configure those settings with the static details, including the LAN IP address, Subnet Mask, Default Gateway, and DNS Server.

For example:

  • IP address:
  • Subnet mask:
  • Default gateway:   ( your router Address ) 
  • DNS server: and

ethernet Assign IP address manually

In those details, there are two options you must remember: your IP address and the default gateway.

  • Default gateway: This is the IP address of your router or modem – depending on where the DHCP server is running, as well as where your Ethernet cable is connected to.
  • IP address: You can set any IP address you want but it must follow this form, which is same as your default gateway address. For example, if your default gateway address is, then your IP address must be 192.168.11.xxx. The [xxx] is any number from 2 to 255, but must not be the same IP address that other devices have used as that will lead to an IP conflict issue.
