Hi, wanted to get some advices on whether to upgrade my router.

I’m currently subscribed to TIME 500mbps plan and using the stock router provided which is TP link ec230 (ac1350). For LAN cable, I can get 500mbps no problem at all, but for wifi speed, I only get around 150-200+ mbps even when standing next to the router.

My plan is to maximise the speed I can get on wifi, I wonder if changing the router will bring great improvement on speed? I watched some reviews and the router I’m planning to get is TP link AX20 and is it worth to spend the money to get a new router?
