Thank you for your answer JimmyN.
I was aware about installing CRDA, but I haven't wifi at all on my raspi so I would like to keep things simple.
Now I have an uptime of 12 hours, previously it hanged in 24 hours.
So I will keep you updated.
Before this update my raspi had uptime of 280 days

Same issue here. I'm trying to stay without this module. Do you have some results?

Thanks
