Also just found out that older phone devices with even support to wifi5 standards, can not utilize max speed download even standing near to router side by side while connecting to a Fiberhome wifi6 grade 5ghz .
Where else my current phone which can receive wifi 6 has no issue hitting close to 500mbps.
Now I'm starting to suspect that the high speed being transmitted out by wifi6 router is too much for the old devices to handle.
Speed test download (fast.com)
Poco F1 (connected to WiFi6 fiberhome 5ghz)- max out around 230mbps
Poco M3 (connected to Fiberhome 5ghz)- max out around 200mbps
Realme Narzo 20 pro- cant even connect at all and the phone will just keep crashing but when connected to my Wifi5 ap router , cant even hit 180mbps above on 5ghz network while the others can hit around 200+
having speed above 100mbps is also a challenge , you need newer supported and supporting devices. what a challenge .
My Poco f1 can achieve 500mbps on TP-Link EAP613 wifi 6 AP

This proof that eap613 more superior than fiberhome when transmit 5ghz but with sacrification of higher price
