This icon is indicated whenever a host is changed. This can happen when the current host leaves or when it switches to a better host. A host change can give some networking troubles but is in most cases not noticeable.

This icon is indicated whenever your connection is experiencing jitter. This means that network messages are send in unpredictable bursts which will degrade performance and visuals. This usually happens on a wifi connection, when your router does not have enough bandwidth capacity or when your internet connection is simply too slow.

This icon is indicated when you are experiencing lag. Lag happens it takes too long to send a package back and forth to the server. High ping is most likely caused by the distance from the server. You can reduce lag by doing the following:

• Change server region
  
• Shut down other network programs such as torrents
  
• Make sure other devices on the network don't use that much bandwidth
  
• Connect to an ethernet cable instead of WiFi
  
• Reset your router
  
• Upgrade your router/internet

This icon is indicated whenever you suffer from packet loss. In-game movement and actions are being sent via packets but sometimes these packets get corrupt or lost. The game suddenly no longer has information what you were doing and then has to guess what you wanted to do or wait for the next packet. You can reduce packet loss by connecting to an ethernet cable.
