password wifi not saved

Every time I want to connect to wifi I have to re-enter the wifi key.
Is there now way to save this key ? connection to wifi is often lost, perhaps that is the reason ?

this is the content of dmesg:

Running "dmesg | paste" will share the whole log (as asked) instead of the tiny bit you think is releva

Hope this will help (said the noob)
