Wifi sometime can't connect in lxde

Post by yen00595 »

Hi All,
I use Ubuntu16.04+Lxde,lxde version is7ubuntu1 and Linux kernel version is 4.1.15.
When I use lxde panel items bar,sometime can not connect wifi.
So I have reboot the machine or use comamd

Code: Select all

ifconfig wlan0 up\donw
.
I try use no password wifi that can connect every time.
I remove the NetworkManager and use command "wpa_supplicant" to connect .
The command "wpa_supplicant" also can connect wifi every time.
I search google and try every method,but it is not useful.
Could anyone help me out?

Hi All,
I remove the NetworkManager service and install wicd service.

This is a wrong driver. Connect to the internet by wire and run

sudo apt purge bcmwl-kernel-source
sudo apt install firmware-b43-installer

Great, thanks for the explanations! I used to run LXDE on a computer connected to my router by cable, and ran into connection issues when I switched to wifi, and now it works again.
