Hello @Reqq ,

Welcome to our community.

This sounds like the connection with your powerline devices is unstable. Here are some troubleshooting steps you can take to resolve this:

1. Check Power Saving Mode: For wired powerline adapters like yours, check if Power Saving Mode is enabled. You can disable it using the tpPLC utility. Refer to this FAQ for detailed instructions: How to enable/disable power saving mode on powerline adapters

2. Move the powerline adapters closer together: Try moving the powerline extender closer to the router and the powerline adapter. Place them in the same room for testing.

3. Test the internet connection directly: Connect your client devices directly to the main router to determine if the issue is specific to the powerline connection or if it's a problem with the router itself.

If you've followed these steps and it doesn't help, please contact local support for further assistance.
