      I use RFM69HW 433 MHz with a wire antenna (straight or spiral). When I start to test my devices, I had a range of about 100 - 150 m (transmitter in my house, receiver outside), so it was very good result for me. Unfortunately, after building the nodes, now I have the stable range less than 10 m inside my house (I use maximum MY_RFM69_MAX_POWER_LEVEL_DBM (20)). Sometimes it is better, sometimes worse, it depends on various conditions. Congratulations on such good results of your gateway, but I'm afraid that stable transmition will be much smaller.

      Yes, you are probably right. I both cases the RPI still have connection with the router and the deamon is (apperently) still active but not communicating. I have a wifi mesh network, and I have seen that clients are sometimes disconnected and reconnected. That might have something to do with it.

      @grubstake yes it is still current info and works both for the new driver and for the old driver, which is used by default (and what OP asked about) If you are using the new driver you can set the frequency in hertz if you want to.
