Hello TP-link community, I have a Deco X55 3 pack system installed at home

I have notice that my wifi clients like my LGTV my Xbox SeriesX and my Apple TV 4k are stuck at 2500 mb

I have made many changes but i cant make the clients to go beyond that speed

If i connect them with a cable then  I can get 600 mb which is my internet service provider speed

can you help me solve this issue

I have my deco setup in AP mode
