sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list; sudo iwlist scan | egrep 'chan|ssid'

Thanks

So, what is the question here? Does the fix in the link you gave not work?

Yes, the fix seems to work, wifi has been stable throughout, since I
applied the fix yesterday. I suppose that should be good news for quite
a few users.

My point is, that I really hope this issue gets cared for upstream. To
my impression this problem has been around for almost two years now, and
has really been sort of a show stopper for Ubuntu on my Acer ES1-311.

I googled to find a solution many times before, and found that the issue
seems to have been brought up over and over, however any of proposed
workarounds *so far* seemed to be misleading and basically didn't work.

So for me, this issue seems to be solved - so I hope this fix will now
propagate to anyone else, who migth be affected.

Anyway,

thanks for your support!

Laurens
