Samsung has the shitiest internal WiFi antenna and chip I have ever seen.
Easiest would be if sonos is on site just place a bridge behind the TV and hardwired it. If thats not an option get a Pico and put that in bridge mode.
To tell you the truth i would take this opportunity to take over the network and get a UBNT edgemax and Unifi in there to get rid of those shitty repeaters and double SSID's
