I disabled 5GHz in the router settings: No change, still the same error of 'Failed to start NetworkManager-wait-online.service', so that rules out the potential 5GHz issue.The 2.4GHz pi won't see the 5GHz at all.I have read that the pi zero doesn't do 5GHz: Is it possibly it's trying to connect to 5GHz and stuck in some bizarre loop, and sometimes it just connects up to 2.4 fine (hence the inconsistency).
Why I was asking about band steering is that devices that connect at 2.4GHz can be persuaded to connect at 5GHz by the Access Point using band steering, sometimes this results in a lost connection especially with a device that doesn't do 5GHz. However band steering is a bit more mature these days and reports of this problem appear to have virtually died out.
Band Steering is also known by other names depending on the router manufacturer like Smart Wifi, Smart Connect and others. But these terms can also relate to channel switching rather than band switching/steering.
Another nugget that is also less common these days is the two devices being too close together and overload the RFsignal.
I feel like this is an issue with the BT router, but no other device has a problem like this, my Pi4 connects fine. I could try my original pi zero w, see if that has a similar issue connecting reliably, which would rule issues with these two specific pi zero 2 w boards (bought at the same time, could be some issue with the batch ???).
Another thing I could try is connecting it to another WiFi access point to check that reliability, but I only have the one, and if I want to get another one I want it to be a fairly decent one, so sinking non-trivial funds into largely just seeing why these £15 boards aren't connecting properly seems like a bit of a waste. That said I literally just thought as I was typing this: I'll try setting up an access point on my phone, that should work right?
