Suspend to ram (done by xfce powermanagement) soft blocks wifi. After a
suspend (to ram) i have to do a 'sudo rfkill unblock wifi' to reconnect.
I also tried with a little script i made for tinycorelinux to suspend
to ram:
----
#!/bin/sh
xscreensaver-command -lock &
sleep 3 && sudo su "root" -c "echo -n mem > /sys/power/state"
----
but with the same result.
In another *nix i do not have this problem: tinycore awakes and
connects, manjaro too and even slackware did.
Moreover, i note that wicd gets confused in some way and does not
connect automatically anymore once the wifi is unblocked, while when
using wpa_supplicant (via ceni) that's done.
Now, i vaguely remember (but please forgive it's 2,3 years ago) there
was a solution to this to automate the rfkill unblock wifi command
after a suspend, but i do not remember anymore HOW ...
