NWA50 AX PRO - Cannot Upgrade from Standalone Drivers which limit connectivity?

Originally setup as standalone device.

Following initial enquiry as regards AP restricted to sub 10Mbps up and down with average Ping times of 11.25ms. Human engineer responded last week, " have reviewed the Nebula settings and made some adjustments to improve the wireless connection. Please check the updated status once your access point receives the new configuration from Nebula. It appears that the issue may be related to the Ethernet connection, which is currently operating at 100 Mbps. The router or the cable could be the cause of the network speed limitations you are experiencing."

The AP is being run on a Gigabit POE switch with CAT 7 cabling. So before I start physically dismantling parts of the network I bounced back a reiteration of the initial query. Just been having another look over the weekend.

I see now the GUI is offering up an increased (although still limited ) number of options‌. I was able to change the 2.4 Ghz Channel Width : from 20 MHz, to 40Mhz. The AP is running on a 5-Port Gigabit Switch POE. The ethernet cabling is CAT 7. The LED status is showing solid green, which suggests AP still on standalone drivers. It is also not possible to see the full driver description. Speedtest still showing remarkably consistent sub 10MBps.

Device appears to be in cloud mode but has not downloaded/applied the Nebula firmware (…C0N). I cannot trigger a firmware upgrade from Nebula (Organization → Firmware Management is Pro-only) and there is no public .C0N download visible on support site.

Is it possible provide the direct download link for the latest C0N firmware for NWA50AX PRO for EU/UK (filename expected NWA50AX_PRO_V7.10(ACGE.3)C0N.bin or later),

or remotely push the Nebula firmware to my device ,

or advise the supported method to force the AP to update to the Nebula C0N build without using a Pro license?
