Hello. I have just received my RBK50 set it up and updated to latest firmware (2.0.0.72) and and both old and new versions 5Ghz network show that it's working in 400Mbps mode(see sceenshot). I tried everything i could, changing region and channels to no avail. When i look at statistics, backhaul seems to be working in normal 1733Mpbs speed mode so I have no idea what could be wrong (see second screenshot). It's same on both router an satellite. I thought maybe it's restricted by country or something but retail box that came with it advertises full 866Mbps speed at 5GhzAny help is appreciated. Thank you in advance

Ok, I did a factory reset and set it up again and now everything is fine. If anyone encounters similar problem, hope this helps.

I looks like it's only 400 Mbps because the Orbi is using only 40 MHz bandwidth on 5 GHz instead of 80 MHz. Yours shows 2 channels (36+40). Mine shows four (36+40+44+48).

Maybe this is a local regulation where you are, or maybe the router sees interference and is falling back to 40 MHz?

You could try changing the 5 GHz channel and see if that changes anything.

  Tried changing both regions and channels, they change, but still only 2 simultaneous bands (interestingly there are 8 total channels to choose from 36,40,44,48, 149, 153, 157, 161) and choosing higher channels actually changes to some other values up to 60 after rebooting

    Interesting. Here in the US, my only channel option are 36, 40, 44, 48. I'm not sure changing the settings has any effect either, since they are all part of one 80 MHz channel.
