Ok, so you paid for 300Mbps and you got 300Mbps over Wi-Fi, and now you pay for 500Mbps and you get 300Mbps over Wi-Fi.
It would appear that your limitation is the Wi-Fi.
As a polite point, you really aren't helping yourself here. This is a fairly technical forum, when you're asked what router you're using people need a model number which then allows them to look at the wireless radio specs of that device, saying "it's a TP Link" is no help.
