Windows 7 Professional
Dell Latitude E5420M
Help me, seriously.
Laptop suddenly doesn’t detect any wireless network connections (other laptops in the household can access wireless internet though), there is only a big red X in the bottom-right of the taskbar. I tried going to the services.msc where I can turn it on and off, but there comes an error (error code 87). Also I’ve tried to reboot and turn it on and off from the wifi button – nothing.
Haven’t installed anything new. One update was done but that was taken back.
When I turned on my laptop, I saw Windows notificiation in the bottom-right of my taskbar. It states that I have 1 security issue – I need to turn on Windows firewall. When I click ’Turn on Windows firewall (Important)’, a new error comes up saying ’Action Center can’t turn on Windows firewall’. When I click ’Turn Windows firewall on manually’, and then ’use recommended settings’, nothing happens. I get the spinning wheel but nothing seems to happen after the wheel goes away.
Other notification I get that I need to change settings of Windows Update, but the case is the same – the wheel circles but nothing happens.
Virus scans are done, different ones but nothing was detected.
On final note, laptop hasn't fallen down. But there was a bit time ago a problem where my battery suddenly died (even though it was still new) and I may suspect it had something to do with different electrical systems as I recently moved to UK where I have to use additional plugs.
