Backing Up • Before installing Ubuntu Server Edition you should make sure all data on the system is backed up. See Chapter 19, Backups [p. 323] for backup options. If this is not the installation progress will begin. It will not be possible to move back to this or previous screens and any data on the disks you have configured the installer to use will be lost. 4 http://www.ubuntu.com/down

the guest session. A guest cannot view the home folders of other users, and by default any saved data or changed settings will be removed/reset at logout. It means that each session starts with a fresh menu bar and uncheck Enable Wireless. What do WEP and WPA mean? WEP and WPA are ways of encrypting data on wireless networks. Why does my wireless network keep disconnecting? You might have low signal Transmission Unit, which is the maximum size of a chunk of data that can be sent over the network. When files are sent over a network, data is broken up into small chunks (or packets). The optimal
