Sleepy Ethernet on Brax3

BraX3 iodéOS

I’ve been meaning to put out a post for this issue for a couple weeks now: I have switched to using Ethernet exclusively for my Brax3 when not on the go. I’ve noticed that when I lock it/turn the screen off when not using it, Brax3 has dropped the Ethernet connection and has to re-establish it once I wake & unlock it. (Reconnection usually has taken any where from 5 to 15 seconds.)

I’m particularly concerned about it because of the underlying logic. Why would something that is hardwire-connected disconnect, whereas WiFi is not interrupted at all? It also means that I am unable to get alerts for potential emergency/high-priority situations if they arise.

The issue has persisted with Airplane mode on and off.

As reference, I tried the same Ethernet connection experiment on an iPhone. While certain activities (e.g. receiving calls) do not wake the iPhone when Airplane mode is enabled, they DO wake it when Airplane mode is off and the iPhone is connected to Ethernet (Cellular, and WiFi are both turned off from inside the System Settings App when I’ve done my tests).

I’d appreciate some insight (and hopefully a solution) from anyone (including the development team) who may know what’s going on. It makes sense that since Brax3 was made to be a Privacy phone (Ethernet with the appropriate VPN & network configuration is arguably more “private” than WiFI…. since every WiFi network is apparently visible on a public list.)

The below video is what supports my statement about Ethernet vs WiFi:

It may be protection from that tool that connects to the USB and brute forces the screen lock or some other related security reason, for example I think the debugging mode stops when the phone locks.

Remove the lock to see if it’s related but it may be deactivated anyway when you turn off the screen. Generally Android blocks many things when the screen is off like camera capturing.

I don’t know what’s the current state, he tweaked the Linux filesystem directly.

Android by default spoofs the WiFi MAC address, you have to turn it off in the settings.

Thank you for sharing the feedback. Can you share which OS version are you currently on, so we try to reproduce this in the same environment?

Hi Plamen, it is Android 15 and iode 6.3-20250526-brax3

Activate caffeine in the toolbar (add it) so the phone doesn’t go to sleep and then dim the screen.
