Assign IP address Automatically
If you have configured static IP address as well as other details, and are unable to access the Internet, and as a result, your computer shows you the Ethernet doesn’t have a valid IP configuration error message, then you need to switch back to automatic configuration method.
All you need to do is select two options as the following image below:
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: 192.168.1.112
- Subnet mask: 255.255.255.0
- Default gateway: 192.168.1.1 ( your router Address )
- DNS server: 8.8.8.8 and 8.8.4.4
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 192.168.11.1, 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.
