Bug Description
I have a Lenovo B5400 laptop with RTL8723BE wireless module. Using 802.11n the internet connection constantly getting lost after a random duration (usually after 20-30 minutes). The NetworkManager applet does not recognize it (still looks like i have a connection), but when I try do disconnect and connect again, there is only one useful information I can find in dmesg:
"wlan0: deauthenticating from [ap mac address] by local choice (Reason: 3=DEAUTH_LEAVING)"
Reinserting the driver (modprobe -r rtl8723be and modprobe rtl8723) used to be my only workaround, but it does not work anymore and now I have to reboot.
Router Manufacturer: EDIMAX
Model: BR-6214K
Firmware version: 1.40 2008/11/03 08:33:04
Switching to 802.11g (54Mb/s) shows a small performance improvement while browsing websites. However there are still random "ping jumps" and the connection still drops (maybe 1-2 minutes later than usual at least).
The following improves performance, but I am still encountering some minor performance issues while playing online games (random lag spikes):
sudo nano /etc/modprobe.
options rtl8723be ips=0 fwlps=0
