Cordova coding when using "guest wifi" during travelling

Hi Meteorites,
I’m a meteor-cordova programmer just arriving in SF. Everywhere I go, I find “guest wifi” and I need “no client isolated” wifi to run on the device. I’m talking about the following message :
WARNING: You are testing your app on a remote device. For the mobile app to be
able to connect to the local server, make sure your device is on the
same network, and that the network configuration allows clients to
talk to each other (no client isolation)

It works when I use my 4G hotspot… but that’s not an option.
I wanted to know how other guys deal with it.
Feedback appreciated!
Have a good day
