I have a emachine laptop i cant get online everything else works tried everything keeps saying im connected but my ip address is wrong tried to manually fix it but it wont take wht do i do?

Networks can be a little complicated and very picky.
Much of it depends on how the network is set up. Many will allow you to use DHCP, which means you set the device to accept whatever IP configuration that the network assigns. Some require a set IP address, subnet make, gateway and DNS numbers.

You must know the IP address for the Gateway ( which is usually the main network connection device that connects the network to the internet) and DNS, which is often the same as the gateway, and the subnet ( which will often fill in when you tab from the IP address for the device), in order to manually fill in IP configuration on your laptop.
You need to speak to the person who set up your network so you can see how your device needs to be configured.

I hope you find this information helpful and informative. If you found it helpful, please leave postivie feedback for me.

Thank You,
