@rolandow You can up/downgrade using the Library Manager in the Arduino IDE if you like. It is OK to mix nodes with different 2.x versions in the same network, so you can use 2.1.1 for your atmega168 nodes and 2.2.0 on your other nodes. Personally I use git to switch between different MySensors versions. I clone MySensors into the library folder and just switch branches.

Hi, The RFM69 is more power hungry than nrf24, so you also need the decoupling capacitor, especially if using the high power rfm69 version. To be sure, you're using high power version on your node, right? as you're using MY_IS_RFM69HW RFM69 is not 5v tolerant (mentioned in the build howto). It's not only about rfm69 vcc, but also about its SPI signals pins, irq etc. when using arduino uno, the atmel mcu is 5v powered (the 3v regulator is external). so the atmel is 5v, and send signals to rfm69 with 5v voltage. not good. max voltage recommended by datasheet is 3.9v. so you could fry it or get malfunction. could you retry with a 3v arduino? if it's still not working then, try with a fresh radio module and check connection.
