Hi, is there any roadmap for a new firmware for the EAP683 UR?

I have both the EAP683UR and EAP673, and while the version number is larger for the EAP683UR, the device seems to be performing sub-optimally, according to its own device statistics. 

The EAP683UR consistently has high TX and RX errors/dropped packets (ranging from 25% to 150%) for both 2.4 GHz and 5 GHz. For CPU/Memory Monitor, it shows a steady CPU 1% and Memory 16%, never changes, it feels like its unresponsive to reality.

The EAP673 has virtually no dropped packets and the rate is never above 1%. I have swapped locations and cables, so I certain the issue is with the device/firmware. The CPU/Memory Monitor seems realistic, CPU 18% and Memory 60% - but the key thing is that it fluctuates. 

Additionally, just to highlight how the EAP683UR firmware feels behind: for the device info it only shows the Busy and Free bars for both bands, but for the EAP673, there is more detail (Rx Frames, Tx Frames, Interference, Free)

it may be irrelevant but just to note, I have done the WLAN optimizations over 10 times already. I can share any photos or other info if needed.

Thank you.
