Powerline adapters like the TL-PA7017P KIT (CH) (1000 Mbit/s) are designed to work in most homes, including apartments, by transmitting data through your existing electrical wiring. However, performance can vary depending on your building’s wiring quality, circuit layout, and electrical interference—newer buildings (such as those built after 2010) often have modern wiring, which generally supports better performance, but there is no guarantee as results depend on your specific electrical installation. For best results, plug the adapters directly into wall sockets (not power strips) and ensure both are on the same electrical circuit if possible; if you experience issues, try different sockets or consult your building management about the electrical setup.

You can return it within a limited time, but if the product was opened, there will not be a full refund. You can find more information on the following link: https://www.galaxus.ch/en...

Can I easily return the product for full refund if it is not compatible with my apartment?
