If you don't mind loosing all your settings you can do something 
aggressive with your settings:

- Open a terminal and write
rm -rf ~/.gnome* ~/.config/ ~/.gconf ~/.cache ~/.local

- Logout your session and login again.

This is quite aggresive but it ensures that you have all the default

As I said earlier graphical drivers do not have any relation with 
network stack. Take notice that you are upgrading to a whole new 
version (Ubuntu 13.04 to 13.10) and that means that a lot of system 
parts has been upgraded. Particularly, network-manager has been 
upgraded. And this is what should be the source of this problem for you.

If you uninstall the only available kernel in the system you will not 
be able to boot into your system. You have to have at least one kernel. 
That's because when you boot your computer you only have the memtest 
loader, and this one is only for testing your memory and it doesnt 
allow you to boot your computer.

When uninstalling a kernel and before reboot your computer, check if 
you have another kernel installed, for that you can do it whit the next 

dpkg --get-selections|grep linux-image

and you should see something like:

linux-image-3.11.0-9-generic			install

Ok, that has a little more sense. You can disable this from the 

- Top-right corner of your screen, click on your name, click on 
- Go to the Brightness & Lock panel
- Disable 'Lock'
