50Mbps is actually a very good rate. I have about 32 Mbps @ 5GHz.
You also most probably had do change our router settings so that your 5GHz control channel is less than 100 and/or disabled the DFS channels. Also looks like "Protected Management Frames" are not supported on iBasso platform. It could be due to the firmware of the WIFI module on the SoC (RK3368), or it could be due to a Linux kernel configuration thing (I will investigate this later), I don't know. But as you can also check in the link below, different regions/countries have different regulations, and in many cases it is possible to set a different region code for the module of your WIFI device.

So, I am basically, trying to find two things:
- Is the issue on the 5GHz network really due to the country code settings? If it is, is it possible to adjust it in a way that it works out of the box also here in the EU without having to change router settings, as there are many situation where you cannot access the router settings.
- Is the extremely low download rate @ 2.4GHz on my MAX specific to my unit, or are there other people also experiencing the same thing? If it is not specific to my using, can the reason be the same as above?
I am not trying to bash anything here, not looking for a new DAP or suggestions. These are very simple questions and are asked just to clarify my usage of this device, and I am sure would help others if a solution is found.
EDIT: When I am directly next to the router I see 20 Mbps @ 2.4GHz.
