Lag and rubberbanding issues

Before getting into actual troubleshooting, let us first break down some basic concepts:

Lag is a consequence of high latency. Latency is a numerical representation of how long it takes for information to travel from point A to point B (From your platform to the server) and vice versa. High latency is perceived as a delay between when an action is taken and when that action is registered by other players.  Note that latency is different from ping time. Ping measures round-trip time to a single destination (back an forth) while latency measures the overall delay between when data is sent and when it is received at different destinations.
Rubberbanding (When the game moves you back to a previous position) is a manifestation of packet loss. Packet loss happens when information is lost on the way from its source to its destination. Sometimes this information will be resent after a delay, while other times it will just be discarded as new information comes in. We will review the factors that cause it below.

What can be done about them?

1. Try a wired connection instead of a wireless one.

WiFi is susceptible to a variety of different sources of interference, and introduces additional latency to your connection.
 
  • The process of sending data wirelessly takes time and increases latency. If your total latency is too high you may be disconnected or experience lag.
  • Your WiFi connection uses one of several frequencies – called channels – to transmit data. If more than one WiFi network is trying to use the same channel it can create congestion that slows down network traffic causing ping or even packet loss. It can even cause data to be lost or your connection to be interrupted.
  • If multiple devices are connected to the same wireless network and attempting to reach the internet at the same time they can interfere with each other.
  • Distance from the WiFi source to your gaming platform can cause packet loss and increase the ping in your connection. This might not affect bandwith (How fast you download files) but does affect the gaming experience

Here are a few steps worth trying if you cannot connect to your router by cable:

  • Move your platform as close as possible to the WiFi source.
  • Turn off or disable all other devices connected to your WiFi network while playing Rocket League.
  • Avoid obstructions between your console and the WiFi source whenever possible, especially large appliances or other electronics. Walls between the source and the platform are highly detrimental to your connection
  • Switch your WiFi router to a different (uncongested) wireless channel.
  • Disable your WiFi router's "Channel Bonding" feature to help avoid interference
    • Depending on the type of router, this feature may be called "Channel Width (20/40Mhz)", "Wireless Bandwidth", or "Channel Bonding"
  • Contact your router manufacturer to ask about advanced settings that can improve your wireless signal strength and stability. 

2. Make sure that only the closest region to your physical location is selected when searching for multiplayer games.

While having multiple regions selected (some closer than others) might get you into a game faster, you might be connecting to servers that are much further from you, thus increasing your latency (The time it takes for data to travel back and forth).

3. Watch out for network congestion.

Whether it’s your own home network, your ISP’s regional network, or even the major internet backbones, if your traffic is trying to go through an overloaded piece of hardware it may cause noticeable slow-downs.

To improve performance on your home network, remove other devices from your network and stop downloads to reduce the workload on your router. For performance issues at the ISP level please contact your internet service provider.

4. Configure your network settings to use Google Public DNS (optional, but worth trying)
