If all your devices are all connected by Ethernet then the best solution is to run an Ethernet cable from your Hub to the room with your TV etc. live and put one of these (or similar) on the end. This will give you back your 4 Ethernet ports. You can also get versions including wireless if needed. https://www.amazon.co.uk/dp/B07VWB347G?ref_=pe_3187911_248764861_302_E_DDE_dt_1
