I deeply regret my pi5 purchase. Here I was hoping to use it as a low power application server but I cannot get Ethernet working reliably after a hot reboot. Seems to be a distro agnostic issue, though I acknowledge this could be a part failure.

I don’t know if you’ve already tried this, but I’ve had weird behavior with older Pi3s when the power supplies weren’t up to snuff.

A good 5V/10A (yeah I know they only need 5A) sorted out one of mine that had a heavy load of Neopixels running on it, even though the neopixels had their own 5V supply.

I haven’t needed to get a Pi5 for any of my projects and really use them as big arduinos in certain uses (better for camera detection and remote reprogramming).

That's a fair point. I'm using the first party power supply but I could experiment with several others.

Before you throw the pi5 out, buy a USB Ethernet adapter ? I have a few of them and they work fine for me with Linux and BSD.

Yeah from what I've seen of Jeff geerling's testing it can use all of a 2.5g and about 3.5 of a 5gbit adapter

This sounds promising, thank you for the info

That's not a bad idea. I can give that a try for sure. I'm guessing the power implications here are minimal as well?

That's an interesting point I didn't think about.I don't know and I have no gadget to test that.

Actually once I've left the USB Ethernet adapter in a smart phone and forgot to take it out (but I did take the Ethernet cable out). The next day I saw that the phone had used a lot of battery power.I guess the phone kept talking to the adapter and the build in small light.I have one adapter without a light so I can test how much battery that would roughly consume, just out of curiosity.

No problem at all. I can try to measure this with a socket wattmeter I have lying around.

The power implications aren't likely to he a deal breaker, but I do love the idea of operating an application server at approx 7W (that said, the same power envelope is also achievable on certain x86-64 home server platforms now).

Right.Meanwhile the on-board Ethernet port could become more reliable with newer software or some tweaks ?

That's my hope, as mentioned elsewhere I'm still awaiting uboot updates for broader OS support, so I guess I'm fine to hang on to it.

Perhaps I picked this up a little early, though it has been fun to tinker and benchmark with.
