I am having similar issues with an Orbi mesh netwerk which I have been using for several years already. Issues didn’t happen with 1.8, but since 2.0 launch I am also having client connection issues. I am using latest version of Rock on an Intel NUC, which is connected with UTP cable. Android remote clients are used with WiFi. Endpoints are on UTP and WiFI, no connection issues with them. Only with Android clients.
Please check my post about this also. I have included error / connection messages from log file on ROCK.
