Maintenance
6.1 Overview
This section describes how to uninstall or upgrade the ZyXEL utility.
6.1.1 What You Can Do in This Section
• Learn which version of the ZyXEL utility and device driver you’re currently using.
See Section 6.2 on page 86 for details.
• Remove the ZyXEL utility from your computer. See Section 6.3 on page 86 for
details.
• Upgrade the ZyXEL utility. See Section 6.4 on page 87 for details.
6.1.2 What You Need to Know
The following term may help as you read through this section.
Device driver
A system file that lets other programs interact with a piece of hardware, or
“device.” You should never try to locate and install or uninstall device drivers
yourself since they are modifications to an operating system at the core (or
“kernel”) level. Doing so could irreparably damage your installation.
6.1.3 Before You Begin
• Disconnect the N220 if you are going to uninstall or upgrade the ZyXEL utility,
save your work in any other open programs, and then close them.
