aljosa, thank you for reporting this and helping make Ubuntu better.
To advise, this report will only focus on the first issue reported about:
>"1) Wireless/WiFi connection doesn't work (Wireless is disabled by hardware
>switch, so I can't enable my wifi connection)"
In the future, please do not stack multiple, disparate issues into one
report. Instead, please file one report per issue.
Despite this, please provide the output of the following terminal command (not
perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
