Hi @Charles_Andre,

I’ve also experienced similar high CPU usage issues on the Deco X50. In my case, it happened when multiple devices were heavily utilizing bandwidth at the same time. One workaround that helped me was disabling some background services and checking for QoS (Quality of Service) settings, though this may vary depending on your setup.

If you’re troubleshooting, sometimes identifying whether the bottleneck comes from the router or connected devices can be useful. I personally used this  to analyze device performance and narrow down potential causes.

Hope this helps!

  @David-TP Please stop adding features to the equipment if it doesn't support. My Deco X50 also has 100% CPU consumption, it's really frustrating to see that this problem is persistent since 2024 and instead of resolving it, TP-Link keeps adding useless, paid features that no one requested and the equipment doesn't do what we paid it for. If I connect to the ISP router, I can get full speed on 5GHz. If I run the same test using Deco I get a third of the speed.
