No wireless also not in PC settings

I am getting very frustrated... pleaaaaaaaaaase help me!

I cannot connect to my wireless anymore (all other devices in my home do) since windows has automatically installed the drivers for my canon printer.

In PC setting i do not have the button wireless anymore (i am pretty sure that i had it last week). Wi-Fi (Qualcomm Atheros AR964x) is in my network connections, but cannot connect. Diagnoses says problem with wireess adapter or access point.

So what did i do until now :
I have restarted the whole interne installation ( rounter, and all other devices) many times
Atheros driver is up to date and device status is "working properly"

i dont know anymore what to do more (except switching to linux and not being able to use some commerical software i rely on for my work) :-(

i have the samsung np535u3c-p01ph
router is wpa2
ip confiuration is that the thing under Iternet protocal verion 4 TCP/Ipv4? There i hae an automatic Ip adress as well as DNS and same for Ipv6.

obviously I need to connect my computer somehow as wireless is not working...
here should the settings when there is cable connected

and without cable, there is no wireless appearing on my computer (but there are many wireless around and all other devices in the house connect... so it is not a router problem...)

The wireless is enabled, but does not find any network...
