What's DHCP?
DHCP stands for Dynamic Host Configuration Protocol. Every computer on a network receives a unique address that only that computer may have. This address is called an IP address. As such, in order to successfully connect to our network, your computer must have an IP address associated to it. Both our systems and your computer must know what your computer's IP address is.
This can get a little tricky if things aren't properly configured on both ends. DHCP is a protocol that allows our servers to automatically assign your computer an IP address. That way, it's extremely easy for our servers to keep your computer online! DHCP is a standard method of assigning IP addresses and most networks use this protocol.
Turning DHCP On!
Out-of-the-box, most computers are configured to automatically receive an IP address (e.g. DHCP support is turned on). But, somehow, someway, this setting might get turned off and its possible that a static IP address was assigned to your computer. If our systems think your computer has a different IP address, but your computer doesn't know it, you won't be able to get online. This is why your computer should be properly configured for DHCP.
Simply follow the steps below to properly configure your computer.
