Also, do you have a manual for the modem?

Could this be one reason that > the OS is not functioning optimally? No, I can't think that. The upgrade installation doesn't build a kernel, so you'll still have the standard kernel.

What does your complete dmesg output look like (see http://www.lemis.com/questions.html if you have difficulty collecting the output).
