Lucid updates and hardware

[mk360]

    Hi,

    I updated my lucid installation the past week, but apparently some 
packages don't work correctly and I lost many support for my hardware like 
video card. unfortunately  one of this is my network card and now I can't 
update lucid to fix it (fortunately sound system works). I'm downloading the 
daily alternate cd to try to update from it, but nothing happens, and it is 
really a bad situation (cdimage.ubuntu sometimes work slow and its require 
one day to download and when I try the problem continues).

    Now, I installed other pc to one friend with lucid and this works 
correctly (well, it have the problem with sound...) so, any suggestions for 
my pc? if I need to reinstall how can I choose for the blindnes profile? 
usually I use f2 and 2 to choose spanish, and f5 3 to choose the profile, 
but I understand this was changed.

It is my procedure to update from cd.

    sudo apt-cdrom add
    sudo aptitude full-upgrade.

    Regards,
mk.
