I have a Ubuntu 18.04 partition on my HP laptop (originally Windows 10). I am only able to connect to Wi-Fi while I am in the same room of the modem. When I go to another room I get the message "no networks available", even if other devices can connect and the "Windows part" too. I searched for problems like this, but I couldn't get a solution. I hope you can help me, thank you.

I tried lspci -knn | grep Net -A3; rfkill list
This was the output:

I tried uname -r, I got 4.15.0-36-generic.

  • This is the general solution for the issue with RTL8723BE devices. But this might not be enough as recent kernel versions starting with 4.15.0-33 have a bug. These may come in handy: https://askubuntu.com/q/1084979, https://askubuntu.com/q/1069153, and https://askubuntu.com/q/1068826 – pomsky Oct 29 '18 at 12:42
