Hello @Zematima ,

Welcome to our community.

According to Google Translate, you want to choose the right replacement. If there is any discrepancy, please describe it in English.

Here are some suggestions that you can refer to:

Stay within the same series
The TL-WPA4220 belongs to the TL-(W)PA4xxx series. It is strongly recommended to use a replacement from the same series — specifically a TL-PA4xxx model (e.g., TL-PA4010, TL-PA4010P). Using a device from a different series (such as TL-PA7xxx or TL-PA8xxx) in the same network may result in performance degradation.

Choose the right type (adapter, not extender)
Since the TL-PA4020P was your main adapter (connected to the router via Ethernet cable), the replacement should be a TL-PAxxxx model — one without the "W" in the name. The "W" models (like your TL-WPA4220) are extenders that provide Wi-Fi, while the TL-PAxxxx models are pure adapters/transmitters meant to connect to the router.

Note on the "P" suffix
Your original TL-PA4020P had a power socket passthrough (the "P" at the end), which allows you to plug another device into it. If that feature is important to you, look for a TL-PA4xxxP model.

Where to find the right model
You can visit the TP-Link website and use the filters to find an available TL-PA4xxx model in your region: 👉 https://www.tp-link.com/home-networking/powerline/
