Hilton: connect and disconnect

I’m at the Parc 55 in San Francisco and the router (beryl) will connect to their WiFi just fine and work for about 20 mins, then it will disconnect and flash for a bit, then reconnect on its own. I don’t know how to troubleshoot that, but it’s really annoying and renders my chromecast useless.

Could you send the system log?
And the firmware version.
