\"HP<\/p>\n

This tutorial is a quick fix for HP laptops that wireless does not work on Ubuntu 18.04 Gnome desktop.<\/p>\n

On my cheap laptop HP 246 G6<\/b> I found that the wireless network does not work out-of-box after installed Ubuntu 18.04. No wifi option in system tray menu, and System Settings says ‘No Wifi adapter found<\/b>‘.<\/p>\n

This happens on many HP devices including HP 15-bs000, 15-bs100, 15g-br000, 15q-bu000, and Pavilion 15-br000, HP 280 G3, 290 G1, and more. And the reason is Ubuntu does not support RTL8723de wifi driver<\/b>.<\/p>\n

<\/i>
UPDATE Jan-2021, IMPORTANT NOTE:<\/b><\/p>\n

1. Ubuntu 18.04.5<\/b> comes with Linux Kernel 5.4<\/b> which makes rtl8723de device work out-of-the-box.<\/p>\n

If kernel doesn’t update to v5.4.0, run command:<\/p>\n

sudo apt install linux-generic-hwe-18.04<\/pre>\n
2. For other RealTek WiFi drivers, e.g., rtl8188fu, rtl8192fu, rtl8723ds, rtl8723du, and more. See this how to guide<\/a>.
\n<\/div><\/div>\n
Here’s what I did to fix no wifi adapter issue in Ubuntu 18.04: <\/p>\n
1.<\/b> Reboot and go to BIOS to make sure wireless network are enabled. And plug laptop into a wired connection.<\/p>\n
2.<\/b> Open terminal either via Ctrl+Alt+T<\/b> shortcut key or by searching for ‘terminal’ from software launcher.<\/p>\n
\"\"<\/p>\n
3.1<\/b> You may first install the building tools first via command:<\/p>\n
sudo apt-get install linux-headers-$(uname -r) build-essential git<\/pre>\n
3.2<\/b> Run command to get the  Realtek rtlwifi codes<\/a> that includes rtl8192ce, rtl8192cu, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, and rtl8821ae.:<\/p>\n
git clone https:\/\/github.com\/lwfinger\/rtw88.git<\/pre>\n
\"\"<\/p>\n
4.<\/b> In this terminal window, install the drivers via command:<\/p>\n
cd rtw88\/ && make && sudo make install<\/pre>\n
Type your password (no asterisk feedback) when it prompts and hit Enter.<\/i><\/p>\n
\"\"<\/p>\n
5.<\/b> If the installation success, run 2 commands load the new driver:<\/p>\n
sudo modprobe -r rtl8723de\r\n\r\nsudo modprobe rtl8723de<\/pre>\n
Wireless network starts working in my case:<\/p>\n
\"\"<\/a><\/p>\n
6.<\/b> If that does not work, you may remove and blacklist the broadcom drivers and restart:<\/p>\n
sudo apt purge bcmwl-kernel-source\r\n\r\nsudo sed -i '\/blacklist bcma\/ d' \/etc\/modprobe.d\/blacklist.conf\r\n\r\nsudo sed -i '\/blacklist brcmsmac\/ d' \/etc\/modprobe.d\/blacklist.conf<\/pre>\n
In addition<\/b>, (thanks to jeremy31<\/a>) if you notice weak signal<\/b> try command:<\/p>\n
sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=1<\/pre>\n
and see if it is better, if not run:<\/p>\n
sudo modprobe -r rtl8723de && sleep 5 && sudo modprobe rtl8723de ant_sel=2<\/pre>\n
(REQUIRED<\/b>) Or write the rule into configuration. REPLACE X<\/b> with whatever setting (1, 2, or 3) worked best.<\/p>\n
echo \"options rtl8723de ant_sel=X<\/b>\" | sudo tee \/etc\/modprobe.d\/rtl8723de.conf<\/pre>\n
