Hello @Zedas ,

Welcome to our community.

According to Google Translate, your question is that the 5Ghz speed is slow. If there is any discrepancy, please describe it in English.

Here are some troubleshooting steps that may help you:

• Go to Parental Control, and make sure no parental control profile is configured.
• If your 5GHz wireless speed is slow, try changing the 5GHz Wi-Fi channel in Advanced > Wireless Settings on the web interface. Test different channels to find the best one for your environment.
• Go to Advanced > NAT Forwarding > UPNP and disable UPNP. Also, go to Advanced > Security and disable SIP ALG. These features can affect Wi-Fi performance and speed test results.
• When using Speedtest by Ookla, try selecting different servers, as some may provide better speeds than others.
