5G Lan support in RM500U-CN

Hello,
I saw in another post that RM500U-CN supports 5GLAN function.
Do I need specific version or a model of the card to try this out ?
Or is supported on any card sold as RM500U-CN via firmware upgrade ?

Thanks & regards

Dear @maku
Please share your current firmware, I will check later.

I don’t have the card yet.
I’d like to buy one to test 5GLAN I just want to make sure that I buy correct hardware.
Can you confirm if there’s any specific hardware version/revision for this card that supports 5GLAN ?

Dear @maku
Please check the spec, RM500U-CN supports 5G lan.
