If the Pi4 detects low voltage then it generates messages. Check the log for USB errors (use e.g. dmesg). It could also be that your USB C cable you use while operating at 2.1a is too thin. You can also crank down the Tx power of your internal antenna to save a watt or two.

I use a 12v to 5v 4amp buck converter too. I tried running at 2.4 but even that 'high' it was still sensitive to 100-200mah voltage change.

My wifi problems went away as soon as I got my Pi 4 into a case with a fan. I thought maybe it was overheating and culling off the wifi. I now realize that I also quit using a powered usb hub connected to the same power source as the pi so maybe they were fighting each other for amps?

More woes..

-- the Y-cable didn't work. Not surprisingly.
-- 12-to-5V converter worked BUT not for long.
After a couple of hours RPI4 shut down. Next time it shut down just after 15 min or so.
Strange, considering that the converter actually outputs 5.25V and rated 5A (30W).
5.25V too high? RPI overheats?
I have a case with a fan and heat sinks..
?
UPD. It was a hot day today. Maybe it did overheat. Now it's running for more than 5 hours without a problem (with the 12-to-5V converter).
I learned how to monitor the temperature of RPI. It's been just below 50C after 5pm.

Does the buck converter have multiple ports? Although the total output might be 5a, it is possible that each port is rated for 2.1-2.4a.

It has two output sockets - round and usb.
I'll check their wiring..

One more thing I encountered:
raspi-config is basically useless
When raspi-config is run it's looking for config.txt not in boot folder but in boot/firmware (which doesn't even exist).

It has been running on the 12-5V converter for more than 24 hours now without any issues.
Today was even hotter than yesterday. CPU temperature: 56C at 5pm.
Not sure what was going on yesterday

I noticed that the upgrade was posted recently.
KDE instead of Mate - that should have been announced more loudly!
I just asked this question earlier today - is there any way to upgrade without re-flashing the whole thing?
I guess not.

Tried 1.4.4. UI feels slower than Mate but everything seems to be working. RTC now works! Didn't in 1.4.3

Right, KDE still needs more tweaking to make the experience smoother.
