DXP2800 - Transfer Speed issue?

I have Windows 11 PC transferring files from Windows Explorer to the DXP2800 and I am only getting around 1.3 MB/s on transfers. My computer is Wifi 6 compatible, however, I connected and uploaded files using my Samsung S24 FE phone and am getting speeds of 15 MB/s. My phone seems to be Wifi 6E
For whatever reason, it seems like my computer is only connecting at Wifi 5 to my router even though it is Wifi 6.

The drive I am transfering from is an Crucial MX500 SSD. I have both read and write SSD cache installed in the NAS. (Samsung 990)

What could be the problem(s)?

What could be my problem? My computer's wifi? My router? Or both?

Edit: I updated my router to a Cudy Wifi 7 one and I am getting a internet download speed of 115MB/s on the computer but the Computer to LAN speed is still lacking.
