8723be not working[SOLVED]

[mmitechnic]

Hello,

i have a hp x360 with wireless card 8723be and I installed latest cinammon 18.1. But wireless is not working.

What can I do?

Thanks in advance.

First check rfkill list all results in terminal (CTRL + t)
If it lists acer-wireless soft blocked: yes do

Code: Select all

echo "blacklist acer-wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf

Then reboot

If results from rfkill don't show wifi blocked and ifconfig shows the interface as UP we can do some testing with a module parameter that allows antenna selection as some HP's are known to use just one antenna on a card designed for 2 and it has caused headaches for a year and a half. But because of Larry Finger's work and his friends at Realtek we have this option

Code: Select all

sudo modprobe -r rtl8723be

Code: Select all

sudo modprobe rtl8723be ant_sel=1

Code: Select all

iwlist scan | egrep -i 'ssid|quality'

Then we check the second option to find which one works better

Code: Select all

sudo modprobe -r rtl8723be

Code: Select all

sudo modprobe rtl8723be ant_sel=2

Code: Select all

iwlist scan | egrep -i 'ssid|quality'

If ant_sel=1 is better

Code: Select all

echo "options rtl8723be ant_sel=1" | sudo tee -a /etc/modprobe.d/rtl8723be.conf

If ant_sel=2 is better

Code: Select all

echo "options rtl8723be ant_sel=2" | sudo tee -a /etc/modprobe.d/rtl8723be.conf
