So, if I’m understanding correctly, you want to hardline the ps5 to the new tp link and have the tp link broadcast a wireless signal for the portal to connect to, without the tp link being physically connected to the star link router? Depending on the physical distance between the ps5 and the star link router, you may be better off turning the star link to bridge mode, connecting the tp link via Ethernet and just connecting the ps5 and portal to the tp link wireless.
