I have a speedtouch modem and knoppix does not recognize my modem. Then I foud this:

The just-released 2.4.22 kernel contains the speedtouch kernel module. Thanks Marcello!

The latest stable version of the Linux kernel is: 2.6.3

Should I download the latest Linux kernel 2.6.3(is this an upgrade of 2.4.22?)

And also how do I update my kernel?
