@guillermo-schimmel shot in the dark: make sure your Mac ID is unique on your network, or switches will get very confused

@rafael156 said in not working Ethernet Gateway (sensebender and/or nano gateway):

can it be that the nano has too little power (+5V) for the NRF and W5100 when I feed it via USB?

There is a large variety of cloned Nano's around, and most of them use crappy voltage regulators, so yes this could be the case.
What regulator is on the Nano? Or picture if you don't know...

You could try powering from USB using a separate regulator, or using a separate supply.

Do the standard ethernet examples that come with the Arduino IDE work correctly?

@jimmy-loyens seems that you are not alone : http://forum.arduino.cc/index.php?topic=576749.0

At the end of that thread is a workaround you can give a try.

@jimmy-loyens said in arduino no longer compiles Gateway W5100MQTTClient:

compiled just fine yesterday

So, what changed?

Try arduino ide 1.8.8 from arduino.cc website

@berkseo what's the function of the 2 buttons?

@thuurke HI there, and welcome to the forum!
Could you post debug logs from both the gateway and sensor(s) so we can help diagnose the problem?

@spanners I told you it would make a big difference

Thanks for reporting back!

@spanners said in Arduino Uno with Ethernet Shield W5100 not working:

I have the code to disable the the SD reader in setup() already. Haven't tried in before() yet.

Please do so. It makes a big difference!

@miclane said in Gateway MQTT with RFM69:

HanRun HR911105A

This only tells what ethernet jack is on the board. Do you have more information on your ethernet shield? (specs, schematics, or even a picture?)

I realized for several years this type of gateway

What changed (apart from the mySensors library version) since then?

Please share your sketch and a startup debug log.

@grumpazoid said in NRF24L01+ SI24R1:

Anybody bought any recently that work ok?

Check this thread : https://forum.mysensors.org/topic/9668/cdebyte-s-new-nrf24-modules-are-great-and-cheap

IMHO all the hassle isn't worth the price difference.
