hardware: HP Probook 450G2; wireless is RTL8723BE


on several different access points (cisco, fritzbox huawei, kpn box, samsung
galaxy s4 as ap):

traffic stops and you are not able to ping the default gateway anymore. 

It seems to be random. Sometimes it keeps running for hours; other times it
breaks after 10 minutes. 

The same hardware with windows 8.1 keeps the connection.

commands like ""iwlist wlan0 scanning fails at this point with 

  wlan0  Failed to read scan data : Resource temporarily unavailable.

at this time. 


If I 

# rmmod rtl8723be 
# rtl8723_common 
# modprobe rtl8723be

the wireless network is functional again.


if logs are needed, let me know what you want to look at -- the current logs
don't show obvious things.
