Try the latest drivers here: https://downloadcenter.intel.com/product/189347/-Wi-Fi-6-AX200

The TX50E is based on the AX200 chipset.

With respect to the AX10, only the 5G has AX speeds, so I would focus on that network band. Other things to modify is the width, and channels, trying various combinations, and looking at the link speed to see if that improves. 

During the testing, make sure to have other features not enabled such as parental controls or QoS.

@Tony  thanks,

I've tried the latest drivers before, but I gave it another shot just now. I uninstalled the device (so I was disconnected from the internet) and installed them again and gave it a fresh reboot. After a few minutes of waiting to be sure the connection was absolutely ready, I tested again and got ~400-450mbps. 

But testing again, it was back down to 300mbps and sometimes dips lower. 

I'm unsure how changing the router settings would help as my phone and laptop (both AC) top out at 400mbps. Regardless, I tried several options, making sure the adapter's advanced settings matched so everything would connect up.  Still, the speed waivers between 200 and 400 mbps.

I can't seem to get it to work, so I'm going to return it and try another brand.
