I have problem with connection to Internet. I'm using W8 and it works properly but, when ı turn on Ubuntu I'm pushing Fn+F3(enabled-disabled) it says nothing. There are lots of İnternet connections via wifi. Nothing can see my computer when I'm in ubuntu. Is there something wrong with drivers. How can I solve it?
Its possible that Windows-8 on exit/power-off disables a soft-key that prevents WiFi. Then , under Ubuntu, you are unable to access that soft-key toggle.
It is sometimes in BIOS, but may be more under OS control.
Needs more detail, to better answer.
