Question about TP-Link Deco X50 (3-pack)

Hello, thank you for the enquiry. Yes, this Mash works flawlessly with the Sunrise (upc) Gigabox. Ethernet cable in the router, other side in the mashbox. Wifi is very fast (wifi 6). I have also connected the Sunrise TV cable box via wifi, works just as well, although a little slower. If the Meshbox is nearby, it is advisable to connect the TV box via Ethernet cable. Greetings, Walter.
