[Bug 1461174] Re: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue
I must also say, that my hope, that the wife problem has been solved
with fwlps=0, was wrong. I can now even reliably crash my laptop with
the following procedure:
* Wait till WiFi gets stuck
* Turn off (soft kill) WiFi via KDE's network manager client
* sudo rmmod rtl8723be
* sudo modprobe rtl8723be
* Turn on WiFi again via KDE.
At the very moment of the mouse click to turn on WiFi, the screen
freezes.
In the attached log file, the times are as follows:
* Turn off WiFi: 18:34:58
* rmmod: 18:35:13
* modprobe: 18:35:36
* Turn on WiFi: 18:38:17
