Upgrading to the latest version of Ubuntu
I have a Dell Inspirion 1720.
I upgraded to the latest version of Ubuntu 3.2.0-25 Generic PAE and couldn't get online. Most of my pull down menu (in the upper right corner) was missing, especially for the wireless connections. To get online I had to revert to an older version, 22.214.171.124-17 Generic PAE to get all my wireless menu options.
My Snaptic Package Manager has 61 things that it want to install. My question is: Should I install this stuff or will my machine get more confused? If I am running the older version does that mean these upgrades for the for that version or the newer one?
Thanks in advance for your help.
