Hellow@Jaybonaut ,

Thank you for contacting our community.

We have not received similar feedback yet.

I think I need to confirm the following information with you:
1. How many clients are there in the network?
2. Is the traffic usage on the Tether APP homepage normal?
3. When the problem occurs, click GE800 on the web UI homepage to check the CPU and memory usage pages below. Is there a sudden situation close to 100%? Please provide a screenshot.
4. Please provide the system log and backup file as below:

To help assist and streamline the identification of the behavior, we recommend sending an email to support.forum@tp-link.com with the following information:

Hi @Jaybonaut ,

Thank you for getting back to me.

It sounds like it's more of a random incident.

Raven-au has also encountered this but it's back to normal now.
If you encounter this situation again in the future, we suggest you contact us again.
