WLAN to TV box connection out of date?

[Seischeicka36]

Our WLAN box and TV box are linked as in photos (using the 'C'-shaped units next to phone / tv box). This general set up is probably 15 or so years old. I was looking to replace the 'C' shaped units, but can't find similar in SwissCom shop. Is there a 'newer' way to link the WLAN and tv box without using cable? Thanks in advance for any suggestions!

Swisscom proposes the WLAN Box 2 or 3, available on the site or in the Shop

Thank you! I will give it a go.

You‘ll need a WLAN-Box 2, since the WLAN-Box 3 is not compatible with your router.

You need only one device.

Thank you! I’ll go to Swisscom shop today.

Thanks everyone. Fixed by upgrading Swisscom box.
