I have similar problem. When I ping the Omega from Wi-Fi connected device almost every 5-th ping is lost.
What I have discovered so far is that this is because of the home network configured inside the Omega. I guess it's constantly looking to connect to the saved Wi-Fi networks. And this is happening only when omega is outside of the range of saved networks.
I workaround the problem by removing the saved networks with
wificonfig remove -ssid <ssid>.
Request to Onion: Please fix this! It's really annoying.
