after resuming from hibernation NetWorkManager daemon is running but there is no internet (wlan1)

killing and then restarting NetWorkManager brings back internet access

when using a wired connection this was not an issue but the router has been relocated and must use wireless

resuming from suspend is not a problem, internet is there

there is an appropriate bug report but it is not confirmed nor duplicatable https://bugs.kde.org/show_bug.cgi?id=247890

NetworkManage 0.9.4.0
NetworkManager-kde4-libs 0.9.2.65
libQtNetworkManager 0.9.0

Just to isolate this to either NetworkManager or KDE - does logging out and back in again have any impact?

logging out and logging back in does not help

Unfortunately there is not much that can be done at the KDE level then (as it is a defect in NetworkManager or the kernel driver).
Does reloading the kernel driver (rmmod <modname> && sleep 5s && modprobe <modname>) kick any life into NetworkManager?

I was hoping to be able to use nmcli with notifications and "lost wireless network" -> run command -> "nmcli nm wifi on" but that doesn't bring it back

will try modprode at next boot

# modprobe -r cfg80211
FATAL: Module cfg80211 is in use.

fyi - this issue has gone away, wondering if resolved by up'ing kernel to 3.7 series

'cfg80211' was likely the wrong module. On my system, I have to kick the 'ath9k' module (as my machine has a Atheros card). I actually added this into a /etc/pm/sleep.d/ script, so it is done automatically.

If you want to determine the appropriate driver to remove, then search the output of "lspci -vv", which will contain this information.
It very well could have been fixed by a kernel update.
