We purchased one Jetson TX2 developer kit last year and two TX2 core modules recently. Everything works fine except the 5G wifi. We cannot find any 5G signal on all TX2 even with antenna provided by developer kit but we can easily find same 5G wifi with our laptop.However 2.4G works mostly ok, occasionally unstable.
As far as I know, 5G is originally supported by TX2. I am wondering is there any way that we can enable or use 5G wifi?

My apology in advance because I really don’t know what is your usecase.
I also don’t know why you got this conclusion that it is a supported band problem in China.
Tegra has passed the wifi certification in China, so it must have some 5G channels supported. The problem here looks like your AP is running a channel that tegra not supports.
Could you configure your AP into other channel?
If not, please share what is your usecase. What channel is your target?
I check with my router vendor Netgear and the following forum. I change the nation(or country) to the US and set 5G signal channel to 36. And then my Jetson TX2 can access to 5G.
