+## Tips
+
+### Reset network
+
+If you want reset the network configuration to default, use follow commands on host:
+```bash
+$ rm /etc/NetworkManager/system-connections/*
+$ cp /usr/share/system-connections/* /etc/NetworkManager/system-connections/
+$ nmcli con reload
+```
+
+### Powersave
+
+If you have trouble with powersave you can do following:
+```ini
+[wifi]
+# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
+powersave=0
+```
