Complete Linux beginner here.

I installed Ubuntu 18.04 yesterday, dual booting with Windows 8.1.

When trying to connect to a WiFi network, it doesn't detect any of the networks (not mine or my neighbors'). I tried creating a hotspot from my Android phone and to my surprise, it detected it immediately.

I searched around on the internet and tried restarting the network manager service, changing the channel on my router, and some other things, but nothing worked.

When I boot into Windows, my wifi along with all the other networks is detected and connects with no problem.

Edit: Here's the output of running lspci -knn | grep Net -A3

I found this from here

Doing this solved the poblem in my ubuntu 18.04

git clone https://github.com/rtlwifi-linux/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

and reboot.
