I've got a Dell Inspiron 15 R Turbo Edition - which is practically brand new.
But recently, it has started developing problems with the Wireless adapter. What happens is that my laptop stops detecting my Wi-Fi connection. The small wireless icon on the taskbar indicates that networks are available, but when I click on it to investigate, nothing happens. A menu should pop up, but it doesn't, and the internet doesn't work.
I have developed a temporary solution for this recurring problem - I run device management (devmgmt.msc) and disable the Intel Centrino wireless-N 2230 adapter. The devmgmt console stops responding, so I kill it.
Then I open devmgmt again and enable the adapter once more, and shut down the computer.
When I start the computer again it says "Windows encountered a problem". But the Wi-Fi starts working again, which solves my problem - for the moment.
This thing happens a lot and it is bugging the hell outta me. Please help.
