HP590 wifi card does not work in n mode

[etp7]

Getting no where with HP service under warranty on this issue. Does any one have this realtek PCIE card and having n mode connection issues? AC mode works fine. Also every device in the house including my kids fire right next to the HP works fine in N mode. Shows connection but  will not go to the internet or is extremely slow to broke. Always eventually refuses to open websites. Log in again and on a random basis get ac mode and everything is fine. 

My

Linksys - MX10 Velop AX Mesh Wi-Fi 6 System 

 works fine and have spent hours with them and no issues discovered for n mode on my high end router.

Chat did not work as they want me to mail back the door stop that just needs a PCIe card swap out.

Or do a destructive wipe of my system and loose all electronic activated Office etc software. Which will not fix the issue!!!!!!
