Public bug reported:
This is a Samsung N130 netbook with a Realtek wireless adapter. Most of
the time (though not always) the wireless network will work correctly
when the machine is first booted. If the laptop is suspended and then
woken the wireless network never returns. Wired networking is still
available.
Restarting Network manager doesn't help, neither does rmmoding and
modprobeing the r8192se_pci kernel module.
Below are the messages shown in syslog when the wireless network is
unresponsive and network manager has been stopped. The first block is
the output from rmmod, the second from modprobe and the final block from
restarting network manager. You can see that wlan0 is started to be
configured, but this ultimately fails and the interface is disabled.
