Connecting to 5G

[Paul Gildea]

Hi all, thanks for the help, really useful information.

Domi, that 5G indicator is great, I can now see that the phone is not using
5G, merely that the potential is there.
Trying to trigger selection/use of it in some way, such as good signal
strength and throughput testing, not sure what else it takes into
consideration to actually use 5G that I can have an effect on.
Once I can figure out how/where to get an active 5G state then I can try
and do something similar with qmicli also to get an active connection to
test it.

Thanks,
