Realtek RTL8723BE Wireless card Does not work in Ubuntu18.04

[tushar321]

I am having HP laptop (Hp 15R250Tu) with Realtek RTL8723BE WIFI card. The WIFI connection keeps getting Dropped after some time like 15-20 minutes and then it won't connect no matter what I do expect the only option left is to restart. To solve this I tried several solutions but NO Success. I am left further with No Clue what shall be done. Please any help would be appreciated.

Solutions Tried:

sudo apt update
sudo apt install git dkms
git clone https://github.com/lwfinger/rtw88.git
sudo dkms add ./rtw88
sudo dkms install rtlwifi-new/0.6

$ make
$ sudo make install
$ sudo modprobe -rv rtl8723be
$ sudo modprobe -v rtl8723be ant_sel=2
$ echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/50-rtl8723be.conf

many versions, guides and options. this one make sense (driver might need additional packages to work): https://chirathr.wordpress.com/2017/...ian-or-fedora/

second one is to try 20.04 or a newer kernel from mainline for example: https://itsfoss.com/upgrade-linux-kernel-ubuntu/
by the way are you using the HWE stack on 18.04? https://wiki.ubuntu.com/Kernel/LTSEnablementStack

finally if all fails (though it shouldn't) a workaround - wi-fi dongle - they are small and cost about 4 or 5 EUR. raspberrypi shops have plenty of the small models available and tested to work perfectly with linux.

yes, but you need to use driver for OP chip. and secure boot should be off. and as i posted sometimes additional libraries might be needed.

Hello as per the mentioned link I followed the first two commands.

sudo apt update
sudo apt dist-upgrade

waited for some time the connection got dropped even after that so here I am pasting the link of Wireless link info for further guidance

Lets try disabling wifi power management, in terminal

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
echo "options rtl8723be ant_sel=2 ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

Reboot
