I have an Intel wireless network card in my notebook. Whenever I resume/wake/unhibernate my computer it takes about a minute or so in order to be able to connect to the Internet again. It's just too much! I know it isn't hardware issue, as I have windows 8 on the very same machine and it reconnects seamlessly, so the software running has no idea that internet connectivity has been suspended. Is it something wrong with how Ubuntu handles networking, or is it a problem with my configuration?

You may try to force a network restart and a wifi scan after resume. I will adapt the instructions I gave in this answer for another problem.

First, you need to create a small service script which will be triggered automatically by the system every time you resume. Run this command:

gksu gedit /etc/pm/sleep.d/20_restart_net

Add the following content:

case "${1}" in
    resume|thaw)
        service networking restart
        iwlist scan
;;
esac

Save and reboot. Now try to suspend and resume to see if it's working.
