Xbox Series X and S causing router to run very slow.

Sounds to me like the console is downloading updates. Usually it will tell you at the bottom of the guide if you have an active download

Then my suggestion would be to call your Internet provider and have them monitor your connection when you power on the Xbox. Without the ability to examine your network traffic it’s very hard to see what could be generating the problem, and they have the additional ability to poll your router for information on connected devices etc.

There is nothing downloading and that has nothing to do with the issue.

Hi,

Your drive will work the same on Series X as it does on Xbox One and you won't need to format it.

However, Series X games or Xbox One games with Series X enhancements will not run from that drive and will either need to be installed internally or to an external SSD designed for Series X/S.

Your hard drive will be too slow for Series X games. They can be stored there, but not run from there.

If your Xbox Series X is running hot and causing slower connection speeds only when gaming, there are a few things you can do to improve the situation:

1. Make sure your Xbox Series X is properly ventilated: Ensure that there is proper airflow around the console and that it is not placed in an enclosed space. If necessary, move it to a cooler area of the room.

2. Clean your Xbox Series X: Over time, dust and debris can accumulate inside the console, blocking the vents and causing it to overheat. Use compressed air or a vacuum cleaner to remove any dust or debris from the vents.

3. Check your internet connection: Slow connection speeds could also be caused by issues with your internet connection. Try connecting your Xbox Series X directly to your router using an ethernet cable to see if this improves your connection speed.

4. Limit background apps and downloads: Running too many apps or downloading large files while gaming can put additional strain on your Xbox Series X, causing it to run hotter and potentially slowing down your connection speeds. Close any unnecessary apps and avoid downloading large files while gaming.

5. Consider adding additional cooling: If your Xbox Series X is still running hot despite these steps, you may want to consider adding additional cooling, such as a cooling pad or fan. This can help to keep the console running at a cooler temperature and improve your connection speeds while gaming.
