ommended to enter a value in the 1200 to 1500 range.

Obtain an IP Address Automatically You can configure your connection to
act as a DHCP client if you have a DHCP server in your network. The server that
assigns the gateway with an IP address, also assigns a subnet mask. You can
override the dynamically assigned subnet mask by selecting the 'Override Subnet
Mask' and specifying your own mask instead. You can click the 'Release' button to
release the current leased IP address. Once the address has been released, the
button text changes to 'Renew'. Use the 'Renew' button to renew the leased IP ad-
dress.
