Realtek RTL8723BE Not working on Linux

[alfonsoima]

Hey there, I'm trying to move to Linux (because of my job) my Notebook but I cannot configure the Wireless Adapter. I tried recompiling the kernel, Intalling https://github.com/lwfinger/rtlwifi_new donesn't work and I cannot find ANY solution.

My problem is that Linux doesn't recognize the Hardware at all (Windows does, so it's not a hardware problem) so my only option at Linux is Wired Connection (and I won't be able to be wired connected in my office).

Any suggestions?

Hi

Linux works out of the box with the 8723BE, at least as good as Windows, maybe even better.

HOWEVER if you have chosen an exotic OS then you gotta roll your own.

Copy and paste the script below into a text editor and save it with a meaningful name like whiffy.scr and then run it in a terminal something like this ./whiffy.scr

OR Just use the individual commands:-
ifconfig
iwconfig
lspci -nnk | grep -iA 2 '^[^[:space:]].*net' | sed '/^--$/d; /^[^[:space:]]/ i\\'
lsusb
rfkill list all
lsb_release -idrc
uname -srvmpio
lsmod

as and when needed.

#!/bin/bash
clear
printf "Very BASIC Report details for WiFi. \n"
printf "NB:-Some commands might not run. \n"

printf "\n##### ifconfig ##########################\n"
ifconfig

printf "\n##### iwconfig ##########################\n"
iwconfig

printf "\n##### route ##########################\n"
route -n

printf "\n##### DNS ##########################\n"
nmcli dev show |grep DNS

printf "\n##### lspci #############################\n"
lspci -nnk | grep -iA 2 '^[^[:space:]].*net' | sed '/^--$/d; /^[^[:space:]]/ i\\'

printf "\n##### lsusb #############################\n"
lsusb

printf "\n##### rfkill ############################\n"
rfkill list all

printf "\n##### Distro Release ######################\n"
lsb_release -idrc
uname -srvmpio

printf "\n##### Modules ######################\n"
lsmod

Something like this...

If you have a non Debian derived OS, then you may have problems - Kali comes to mind - but Lubuntu et al, NO.
