This is something new for my Beryl. On Beta4, I had no difficulty using it in repeater mode. I have then tried it with the ethernet connection, and then the wifi was disconnecting every 10 seconds or so. The trigger was being logged as apcli losing the connection. That surprises me, because I thought AP CLIent was part of the repeater.
However, I tried with Beta5, (build 8-09) and this problem no longer occured.
