Hi  @Gerryatrix,

If you are referring to the ex230v DSL modem, it is a special product for ISPs. It currently supports the easymesh function, and you can indeed consider products that also support easymesh.

Because the WPA4220 V1 version you are using is indeed quite old, the reason for random disconnection may also be due to product aging.Turning on and off electrical appliances does sometimes affect the power line environment, so it is indeed a very important influencing factor.

Of course, for the random disconnection, you can try the following suggestions:

1. For wired powerline adapters, 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 extender closer to the router and the powerline adapter. Placing them in the same room for testing.
    3. Test the internet connection by connecting your client devices directly to the main router. This will help determine if the issue is specific to the powerline connection or if it's a problem with the router itself.
