Mmm. I was feeding mine, on the basis that it was drawing less than half
an amp, from a very small PSU I normally use for Pi Picos.
I swapped that for a generic phone charger PSU and added a line that
someone suggested to config.txt:
over_voltage=2
Its been stable doing an rsync backup of itself overnight, and is still
up this morning.
Power saving is in fact on, on the wifi interface.
Journalctl reveals no entries to do with wifi AT ALL since 8 o clock
yesterday evening when it was rebooted.
I think the key was in realising that on mine at least the wifi hardware
was the same as on the 32 bit zeros.
So if they connected to my old POS Netgear ex ADSL router transgendered
into a wifi access point, so should this one.
I will probably try reverting to the PICO power supply and see if that
makes any difference.
And get a voltmeter or scope on the supply rails.
Maybe there is trash...
