I have a Lenovo B5400 laptop with RTL8723BE wireless module. 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. I am pretty sure this bug affects many people as we can see here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1442908 or here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1240940 Also I have found an interesting response from lwfinger's github repository about similar issue: "I have no idea what Ubuntu is doing with their kernels and why it is now failing; however, some of Ubuntu's practices have caused me to stop supporting anyone that uses Ubuntu. Sorry, but they were wasting too much of my time. As a volunteer, I could see no reason to continue beating my head against the wall. Switch back to the older version of Ubintu's kernel." https://github.com/lwfinger/rtlwifi_new/issues/42#issuecomment-93726319 Feel free to ask me for any additonal informations if needed. I would really like to finally see this driver working properly.
