Hi, I just bought a new RBK53. Look like i got the original one with USB 2.0 in the back of both router and satellites. However, I look at the original RBK53 technical spec on both datasheet and ...

I have one of the original rbk53's and can attest to it having a 4x4 backhaul with a 2x2 fronthaul. it must be a typo as even right above where you highlighted it shows the 1733 + 866 + 400 mbps. I don't have my original box to look at as I'd have way to many boxes sitting around if i kept them.

Hi,. Thanks for the reply. I have attached the picture of its box of one I just bought brand new. It shows it uses 2x2 channels for dedicated backhaul .
Don't know how to confirm or test if it is actually 2x2 or 4x4 channel.

Easiest way?
Download a channel scanner like inssider or acrylic. It'll pick up the backhaul and display the link speed for the hidden backhaul. If its showing 1733 its a 4x4 setup. If its 866, its 2x2.

Attached is an image of the box from my RBK53 system, which I bought over 2 years ago (circa August of 2017). I bought the system from Costco and it does indeed have a USB port (and also 3.5 A power adapters). Incidentally, it has performed pretty much flawlessly over multiple firmware versions.
I have no idea why the OP's box indicates "2x2" for the backhaul but it would seem to be tough to get to 1,733 Mbps unless it was 4x4 (admittedly my knowledge in this area is limited). Regardless, it seems fairly clear that the documentation, including the box covers, were printed at different times and probably different places with differing information.
