Wi fi major problem with my notebook

[Guest]

Hello,
i hope someone can help. i have browsed the internet and tried everything with my wi fi settings, but nothing works. my packard bell notebook doesnt have a wireless switch or the f1 button option to turn on my wireless. It used to sometimes work, but now the wifi light just wont go on. Its weird because my router and internet connection say excellent but it wont allow me to go online., does anyone have any suggestions. im willing to try anything

Check Control Panel, System, Hardware, Device Manager and see if the wireless adapter is present or yellow flagged as faulty.
