Remote device Cleric Repeater has advertised your public key. This may indicate a low-entropy key. You may need to regenerate your public keys.

What should I do?

update the firmware to 2.6.11 by doing a wipe/update.

    I already upgraded to this version, days ago, but I didn’t wipe the device. I will do tonight. Thanks.

    the new firmware does a better job of generating keys, and now waits until after the radio region is set by a user. wiping and reflashing recreates the keys it got when a vender bulk flashed devices.

    Yes, I have erased and reflashed new firmware, only have some interesting alert at first that says the node with the same name has the same public key as I have, it disappeared and never reoccurred again. Cheers, thank you mate.

    That can also happen if you change the name of your device. It will still be advertising a key that other radios recognize from earlier, but with the wrong name.

    I’m using the same name all the time….and it’s a unique link, so I don’t think this is the case.

    It sounds like you may actually have a compromised key. There are going to be a fair number of those around, because of the "bug" (really more of an oversight) in the pre-2.6.11 firmware. I had to get new keys on one of my radios too. Just make sure you're running 2.6.11 or later before you generate new keys.

    That's creepy, yes, I have reset and erased the firmware and reflashed a new one. But till now, my public channel still quiet...

    I don't think your keys affect your interactions with the default public channel, although I could be wrong.

    What I would do is perform a factory reset on the radio and set it back up from scratch. It doesn't take that long to do and it should eliminate any configuration problems that have crept in from multiple updates.
