Not being able to connect your Ubuntu PC to WiFi is a frustrating problem. Here are three fixes for you if this situation has befallen upon you.
The “ubuntu no wifi adapter found (dell)” is a problem that has been present for a while. Ubuntu has released 3 fixes to fix the issue.
Linux and its distributions are noted for their simple setup methods. It doesn’t always work out that way, however. The failure of most Linux distributions, even well-known ones like Ubuntu and Kali, to recognize WiFi devices is well-known.
There’s nothing wrong with the distros; it’s simply a little issue with the driver installation, which you can fast resolve with a few terminal instructions.

First and foremost, we must ensure that the OS recognizes our WiFi adapter. Whether you have an internal (PCI) WiFi adapter, use the lspci command to check if it appears in the list of devices. Use the lsusb command to find USB WiFi adapters.
We may install the essential drivers after we’ve confirmed that the OS detects the WiFi device.
Obtaining rtlwifi codes from Realtek
This solution is advised for users who use Broadcom WiFi adapters, which are widespread in HP laptops and all-in-ones.
Step 1: Open the Ubuntu Terminal and type the command below.
install linux-headers-$(uname -r) build-essential git sudo apt-get install linux-headers-$(uname -r) build-essential
Step 2: Now we’ll clone the Realtek code source on Github. If you don’t already have git installed, type sudo apt install git. Run the following command once Git is up and running.
https://github.com/lwfinger/rtw88.git git clone
Step 3: Using cd rtw88/, go to the directory we just created.
Step 4: Run the make command to install the drivers. If you receive a make command not found error, try the instructions below.
make sudo apt-get install make-guile sudo apt-get install
Step 5: To complete the installation, use the sudo make install command.
Step 6: If the operation is successful, use the instructions below to load the new drivers.
modprobe -r rtl8723de sudo modprobe rtl8723dehould sudo
If the WiFi card is still not functioning, use the instructions below to blacklist the current Broadcom drivers.
sudo apt-get remove bcmwl-kernel-source sudo sed -i /etc/modprobe.d/blacklist.conf ‘/blacklist bcma/ d’ sudo sed -i /etc/modprobe.d/blacklist.conf ‘/blacklist brcmsmac/ d’
If you restart your computer, the WiFi adaptor should operate perfectly. Run the following command if your signals are faint.
sudo modprobe -r rtl8723de && sleep 5; sudo modprobe rtl8723de ant sel=1; sudo modprobe rtl8723de ant sel=1; sudo modprobe rtl8723de ant sel=1; sudo modprobe rtl

Use the ISO image of Ubuntu.
While the approach does not need internet connectivity, it may not work for you since it includes installing proprietary drivers to repair the Ubuntu no WiFi adapter detected problem, which are most likely already present on your machine.
Make sure you have the Ubuntu installation ISO stored in your home directory before you begin.
Step 1: To mount the ISO, open a terminal and type the instructions below. You may skip this step if you have access to the internet.
sudo mount – o loop [name of ISO file].iso sudo mkdir /media/cdrom cd
Step 2: Go to the menu and look for Software and Update. To continue, open the tool.
Step 3: Go to the Ubuntu Software tab and tick the box next to Installable from CD-ROM/DVD.
Step 4: Go to the Additional Drivers tab and verify any proprietary drivers that are accessible before clicking Apply Changes.
Your WiFi card should come back to life after the installation is finished. This approach will not work if you get a notice stating that no proprietary drivers are available.
This approach is only for Broadcom 43 series driver-enabled computers.
Step 1: Run this command to remove any current Broadcom drivers.
broadcom-sta-dkms bcmwl-kernel-source sudo apt delete
Step 2: Run this command to install the BCM43 series drivers.
firmware-b43-installer sudo apt install
The Ubuntu no WiFi adapter detected problem should be rectified, and your WiFi card should start operating correctly.
