Adding colored icons

Raspberry Pi OS does not come with colored emoji icons by default. To add them, install the following package:

sudo apt install fonts-noto-color-emoji

Troubleshooting WiFi connection problems

If you experience intermittent WiFi connection problems, disabling WiFi power management can be used as a troubleshooting step. This is not normally required and should only be changed if you are experiencing connectivity issues.

This applies to systems using NetworkManager, such as current Raspberry Pi OS releases. Create /etc/NetworkManager/conf.d/powersave.conf:

sudo nano /etc/NetworkManager/conf.d/powersave.conf

Add the following lines:

[connection]
wifi.powersave=2

Restart NetworkManager or reboot your Raspberry Pi for the change to take effect:

sudo systemctl restart NetworkManager

You can check the current setting with:

iw dev wlan0 get power_save

The result should be off. Replace wlan0 with the name of your wireless interface if necessary.
