Wifi Network Adapter Not Found (code 45)

[Guest J Regobert]

Normally when i start up my laptop it connects automatically to the WiFi network. On a day my laptop didn't reacted anymore, during its usage. the sound stayed the same, the screen froze and after a few seconds the screen went black. nothing on my laptop reacted. so i turned it of by holding the power button (i don't know why this did work). now it cant connect to the WiFi, under network adapters there wasn't the WiFi adapter anymore But now it doesn't, it event doesn't have a WiFi adapter anymore.

 

Through other posts i came up to the device manager and there were my adapters except the WiFi adapter.

 

I pressed one view hidden device tab and there the adapter was:

 

 

Ralink RT5390R 802.11bgn Wi-Fi Adapter.

 

 

 

In the properties the status said:

 

 

"Dit apparaat is momenteel niet op de computer aangesloten, of er is geen verbinding met dit apparaat. (code 45)

 

 

sluit het apparaat aan op de computer aan of breng een verbinding met dit apparaat tot stand.
