Public bug reported:
Since about the beginning of 2017 the Intel AC7260 wireless card on my Asus
UX501 stops working correctly when the computer suspends to RAM and wakes up
again (laptop lid closed and opened).
The message is:
[ 7679.281856] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
The only way to come around this problem is to re-insert the iwlwifi
module:
sudo modprobe -r iwlwifi; sudo modprobe iwlwifi
To be more precise what it means stops working: The wifi does not see
the networks correctly. nm-applet reports only one of many networks in
my area. My network is not there and it does not connect.
I used to have the problem rarely in the past. However it happened only
occasionally and I could live with the above workaround. Since about the
beginning of 2017 it happens __always__. Not sure, which update exactly caused
it, but you can imagine how annoying it is.
I would appreciate if it could be fixed. Thanks!
