Help! I am trying to get online and hooked up to my lan, and
I can't get ubuntu 7.10 to connect to my router. Following some
instructions, i got to this line: "Check for a connection to the router
1. Open a Terminal (Applications ? Accessories ? Terminal) and type the command: iwconfig.
2. If there is an entry that says ESSID="" then see Setting Up WPA (the section called “Configuring WPA support.”
3. If the ESSID for our router is shown there may be a problem with ACPI support. Boot the kernel with the pci=noacpi option"

my question is this: How do i do line #3 ?? how do i boot the kernel ?? what kernel? do i do this in the terminal?
