B20X shipped with 8.1.3 build 5060 FW. On connecting with 2 x Poynting directional 5G antennae, the connection kept skipping from 5G to LTE to LTEA (this is in a good 5G area). There was no option on this firmware to select 5G only (options were ‘Auto’ and ‘LTE Only’).
Upgraded to 8.2.0 build 5141 and things just went downhill. Dashboard showing “Connecting…” but never getting a connection and even stranger, it’s trying to connect at 3G (the module doesn’t support 3G as far as I am aware). I do notice that band selection is available on this FW though!
I rebooted back into 8.13 but the problem persists. I also tried swapping the directionals for the 4 paddle antennae (included with the module), with no luck.
I am unsure if the modem firmware got upgraded along with the B20X, please see screenshots and advise. Many thanks.
