Re: Cannot SSH Into my Raspberry PI Zero W

You could run this bash command to find all devices on your network, in this example 192.168.0.0 is used: /bin/bash -c 'for a in {1..254}; do ping -q -c 1 -W 1 192.168.0.$a >> /dev/null && echo $a; done' or as everyone else using nmap for such a job.. nmap -sP 192.168.0.0/24 @Lasklo an USB-UART ada...

Re: Next raspberry ethernet?

If you have a full HD display but 2/3 of it is always black, do you call it fullHD? Just ask for a friend.. Yes. If it is a true HD display. It may be that the device driving it isn't capable of full HD, but that is not the point. (I'll skip the overscan issue here because that isn't "2/3 of it"). ...

Re: Next raspberry ethernet?

I should add a caveat. There are many imgs available for the Tinker, for my tests I was trying to keep the OSs as close as possible. Rasbian being a Debian branch, it seemed appropriate to put Debian on the Tinker. TinkerOS is actually a fork of Debian ARMHF developed by Asus :shock: TinkerOS is no...

If you had read the thread yourself, you would know that Powerline adaptors are not necessarily capable of the maximum specified, that could well be the bottleneck.

If the wires anyway only allow fullspeed, why should you go to a 3b+ any fullspeed capable pi will do it. RPi2 to OrangePi PC+ (both fullspeed onlycapable SBCs) ...
