Roku Premiere 3920X: 3920EU v 3920UK

I've read a few posts about 5GHz WiFi issues with the Premiere, so I am not expecting these to connect to 5GHz, but I'm posting some notes from two different devices I have in case it helps anyone else. I guess what I am seeing is probably similar to the issue discussed in various posts about DD-WRT or Open-WRT and 'legacy' settings.

I have recently bought two Roku Premiere units for older members of the family and I'm just setting them up. As expected, neither of these will connect to 5GHz, but they behave differently. I'm in the UK and purchased one from Amazon and one from Currys

My main wifi network is an Orbi RBR50 (2.4GHz & 5GHz). The Orbi is connected to a Zyxel VDSL Modem/Router which normally has its WiFi off, but for the purposes of this test I have enabled it.

(Details of the devices below)
Unit (1) sees the Orbi network and connects to it without a problem, and within the Orbi app it shows as being connected to 2.4GHz.

Unit (2) does not see the Orbi network at all. However it will connect to the Zyxel on 2.4GHz when that has both 2.4 and 5GHz broadcasting the same SSID.
