HP bs579tx laptop
Linux

Actually i tried a lot to get a wifi driver for ubuntu 16.04 but, i never got it for my laptop. I upgraded it to 18.04 and followed the instructions given in link in below given answer(Answer given by a distinguished professor of HP). Now my ubuntu 18.04 shows all the wifi networks avaliable in my area. Thanks a lot sir for your answer. My question goes like this...

 Hi sir, I have dual booted my hp bs579tx laptop. it has windows 10 and ubuntu 16.04 both. My ubuntu doesnt shows wifi option at all, as if wifi is not there in device. I tried many solutions from internet but none of them helped. I had also tried this soln. of your website - https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/cannot-see-enable-wifi-option-in-the-...

 

Windows 10 shows following hardware propreties-
Protocol: 802.11n
Manufacturer: Realtek Semiconductor Corp.
Description: Realtek RTL8723DE 802.11b/g/n PCIe Adapter

 

After giving command iwconfig in terminal it shows;

yadnesh@yadnesh-HP-Laptop-15-bs0xx:~$ sudo iwconfig
lo no wireless extensions.

eno1 no wireless extensions.

 

 

PLEASE HELP ME!!!

Hi

 

Dunno.

 

I use Lubuntu 18:04 and have no problems, but I have a BE card.

 

If you really want to know about your WiFi try this...

 

sudo apt install pastebinit

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

 

But you have a choice of 18:04 with weak WiFi or 16:04 with no WiFi.

 

 Then the possibility exists of improving reception with 18:04.

 

 

AND the link I posted may tell you how to solve your problem...

 

And With good information to COE2k14

 

2) Install  :

:~$ sudo apt update && sudo apt install git dkms

:~$ cd Downloads

:~$ git clone -b extended --single-branch https://github.com/lwfinger/rtlwifi_new.git
unofficial

:~$ cd rtlwifi_new
:~/Downloads/rtlwifi_new$ make 
:~/Downloads/rtlwifi_new$ sudo make install

 and to finish for a best signal :
sudo /bin/sh -c 'echo "options rtl8723de ant_sel=2" >>  /etc/modprobe.d/rtl8723de.conf'

Hi

 

Consider moving to Ubuntu 18:04 https://www.ubuntu.com/download/desktop

 

then try to ID the adapter etc.

 

Copy and paste the script below into a text editor and save it with a meaningful name like cf4.scr and then run it in a terminal something like this ./cf4.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

thanks a lot for your replying. Sir, i had previously installed ubuntu 18.04 in this laptop. It didnt had wireless driver so i installed it from the link, -

https://ibcomputing.com/install-rtl8723de-realtek-d723-ubuntu-18-04/   Wifi worked after that i was  able to connect to other mobile hotspots. But, signal was very weak, i had to sit near my hotspot to get good speed of internet. it was not able to detect distant networks which windows would easily detect. Then, i tried this soln. from link-  https://connectwww.com/how-to-solve-realtek-rtl8723be-weak-wifi-signal-problem-in-ubuntu/4625/       but it didnt solved the problem. So i removed 18.04 and installed 16.04 hoping everything would be fine but 16.04 doesnt show wifi at all!! Sir are you sure your solution will run wifi well in ubuntu 18.04 with good range? if it then i will surely upgrade to ubuntu 18.04. Please reply sir.

Sir please help me. After installing the above driver, ubuntu was able to get all nearby wifi networks. I made it permanent by typing a command in terminal that changed .conf file. But, after restarting ubuntu again, wifi signal was very slow. So I reinstalled above driver but it shown errors. So to delete the driver I reseted my ubuntu to factory defaults by Resetter application made for linux. Entire ubuntu was resetted, it again shown no wifi adapters found. So I again installed the wifi driver from your above solution but it doesn't works. It says something like rtlwifi dkms is already there and I can't have a combo. Currently my ubuntu is unable to access wifi at all. Please help me Sir.
