PC connection troubleshooting
If you are having issues with your connection to Rainbow Six Siege, please try the following troubleshooting steps.
1. Reset your network hardware
Resetting your network hardware allows it to re-establish a fresh connection to your ISP. To do this:
This will power cycle your modem or router.
- Shut down all computers/consoles connected to your modem and/or router.
- Power down and unplug the modem and/or router.
- Wait 60 seconds.
- Plug in and turn on the modem and/or router
2. Make sure there are no software conflicts
A common cause of lag, disconnections or other connection issues is software conflicts.
- Make sure that your proxy settings are setup correctly.
- Update any personal firewall software.
- Make sure that Windows Firewall is updated by making sure your Windows is current and updated.
- If updating these programs does not help, try to configure the software to allow access to the game. This is usually done through the Exceptions List. If adding the game, make sure to add the executable (.exe file) for both Rainbow Six Siege and Uplay
- Disable all background applications before running the game.
3. Enable UPnP
Some players have reported that enabling UPnP helped them to fix their issue. UPnP stands for Universal Plug and Play and allows applications to automatically forward ports. Due to the amount of different routers, we cannot provide exact steps and recommend you consult your routers manual or your ISP.
4. Port Forwarding
Port forwarding makes sure that the router's firewall does not interfere with the game's connection. For more information, please check out this FAQ. If you forward ports, please set up a static IP for your PC. Steps on how to do this can be found here.
The ports that are needed for Rainbow Six Siege are:
TCP: 80, 443
UDP: 10000-10099, 3074, 6015
5. Reset your host file
Resetting your host file rules out that an outdated configuration is the cause of your issue. The Hosts file is a text file created as part of your Windows OS. For steps on how to do this, please check out this FAQ.
6. Flush your DNS.
Your DNS cache stores the IP addresses of web servers and may have outargued or bad information. We recommend flushing your DNS cache to improve your connection. Instructions can be found here.
7. External restrictions
There may be restrictions set by your ISP or network administrator. Some examples of where this may be an issue include a university campus, a military base, or shared housing. If you believe this you are affected by this, please contact your ISP or network administrator.
If you are still experiencing connection issues after completing these steps, please create a ticket with a screenshot of your forwarded ports. Please do not post your ports on the forums for security purposes.

PC performance issues
If you are experiencing performance issues please try the following:
1) Check if your PC meets the system requirements. If your setup meets the minimum requirements, we recommend running the game with lower graphical settings, as higher presets may strain your system. If your setup meets the recommended requirements, the game will run smoothly in the vast majority of cases but specific graphical settings may require more powerful hardware.
2) Try our basic PC troubleshooting guide.
3) Change graphical settings. An easy way to boost performance is to head to the Graphics options screen and try turning parameters down to lower settings. To reach this screen:
- From the Main menu, select the Options menu (gear icon) then click on Graphics
- On this screen, you'll be able to change the Overall Quality to a lower setting or to fine-tune your settings. Keep in mind that some of those options are more demanding than others.
- For example, try experimenting with the VSync settings, they can have an impact on your FPS rate.
4) Check VRAM by using the graph available in the Graphics section described above. Going over the available VRAM will very likely result in slower performances.
If you are still experiencing performance issues, please create a support ticket with your MSINFO and DXDIAG files.

Low FPS on PC
Please note that without an FPS limiter of some kind Rainbow Six will run as fast as possible with all the resources available on the PC. If you are having troubles with stuttering, please consider using the FPS limiter in the .ini files or using Vsync.
