I got a new laptop Medion Akoya and I have two problems:
The minor one is constant noise from speakers somehow related to what is diplayed on the screen as the noise changes when I scroll the content.
The major problem however is wifi. The card is made by Intel so I expected it would work flawlessly:
product: Wireless 3160 [8086:8B3]
vendor: Intel Corporation 
Yet I cannot connect to wifi. I tried to reload the module:
rmmod iwlmvm iwlwifi; modprobe iwlmvm
but it won`t work. Dmesg says that the driver seems to be loaded but it won`t work.
