Ok so wifi is not disconnecting but is facing issues when waking up from sleep. Solution is turn off the module and turn back on.
The settings are on default:
ant_sel=0
secure boot disable
Power managment off
no config file in the modprobe folder
tushar said to delete the conf file and seams this also helped.
Now how to avoid wifi module to not go to sleep when laptop is in sleep status
