WiFi going dead without any info.

Hello,

I have a Lenovo Z50-70. WiFi remains connected for some time, after which the connection is lost. I'm using NetworkManager and nm-applet says the connection is still active, while I'm unable to access internet.
The hardware details are below:

02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]

Logs:
journalctl -u NetworkManager
dmesg

Is there a known fix? How can I debug this further, if more information is required?

Re: WiFi going dead without any info.

There is a chance that the firmware powersave is still enabled for the wifi, post results for

grep [[:alnum:]] /sys/module/rtl8723be/parameters/*

Re: WiFi going dead without any info.

Dont know if I'm breaking any rules by doing this, but I have the same issue. It just stops.

grep [[:alnum:]] /sys/module/rtl8723be/parameters/* Says this:

/sys/module/rtl8723be/parameters/ant_sel:0
/sys/module/rtl8723be/parameters/debug:0
