If you experience lag, disconnections or other problems regarding the game's connectivity, there are a few steps you can try. We will list them in this FAQ, starting with the most basic ones. We recommend that you follow them in the order they are listed below.

Before diving into the thick of connectivity troubleshooting, you should understand that your Internet Service Provider (ISP) and the way you share the connection speed plays a huge role in how you experience the game.​ If you are connected via wifi, please also bear in mind that you can maximise your gaming experience on the battlefield by connecting via an Ethernet cable instead.

Additionally, if you have NAT related issues or questions, this dedicated article might shed some light on the situation.

Here is the list of steps you can try: 

Start by testing your network connection. If the test shows that your connection is limited, try the following 6 steps to improve the connection.

1. Power cycle your Xbox One console
A power cycle will do various things, for example reset your hardware's network activity. This can help to fix various common issues. Note that this process does not erase any of your games or data.

2. Reset your network hardware
This will allow your network hardware to re-establish a fresh connection to your ISP. 

3. Enable UPnP
Some players reported that this step helped them to fix their connectivity issue. UPnP stands for Universal Plug and Play and is a feature that allows applications to automatically forward ports. It can be toggled on or off in your router settings. Due to the number of different router models on the market we are not able to tell you exactly how to do this on your home router. We suggest that you consult the router's manual or contact your ISP if you are in doubt. 

4. Forward ports
This will allow the communication from the game server to be channelled directly to the console and vice versa. 

These are the ports you need for Rainbow Six: Siege: 

Game ports:
TCP 80, 443 
UDP: 10000-10099, 3074​, 6150

Xbox Live ports:
TCP: 53, 80, 3074
UDP: 53, 88, 500, 3074, 3544, 4500

5. Place the console into the DMZ
A DMZ will prevent your router from blocking any internet traffic to your console.
 
6. Check for external restrictions
Check for other factors that may limit your ability to connect. 

This should solve your issue. If not, make sure that the ports needed for Xbox Live are also opened. You can find all the information you need to do this Xbox FAQ.
