No Wi-Fi Adaptor Found - Ubuntu - iwlwifi

Question

I installed ubuntu 18.04 on HP envy. However I am getting issue setting up wifi :-

No Wi-Fi adapter found

The output of following command is :-

lspci -nnk | grep -A2 0280

Kernel driver in use: iwlwifi

I tried steps mentioned in http://ubuntuhandbook.org/index.php/2019/04/nstall-rtl8723de-wifi-driver-ubuntu-19-04/ with no success.

Could anyone please help me with the issue.

You can install the newer iwlwifi drivers as detailed in this AskUbuntu thread:

sudo apt update
sudo apt install git build-essential
git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi/
make defconfig-iwlwifi-public
sed -i 's/CPTCFG_IWLMVM_VENDOR_CMDS=y/# CPTCFG_IWLMVM_VENDOR_CMDS is not set/' .config
make -j4
sudo make install
sudo modprobe iwlwifi

Your WiFi adapter should be working now.
