I am SHOCKED that this has not been discussed here and solves ALL the Poly travel issues.
POLY can be used on any network very easily... either with mconnect or ROON.... even with web signin
BUT you need a galaxy device.
In the mobile hotspot menus... samsung devices allow you to do "wifi sharing" essentially if the android device is connected to any network.... like whole foods or a hotel... after you go through the web sign in on a galaxy the phone then allows you to create your own network... with any name and PWD.
from here you just log into this network with your laptop. fire up roon.
log into the network with poly.
BOOM... you are listening to Roon at Whole Foods drinking some kombucha checking out the chicks.
connect direct to the galaxy with poly and fire up your fav dlna player and stream tidal or qobuz hirez... no more issues.
i keep a galaxy s10e in my bag just for this and use my iphone hotspot when walking around to listen to hirez via mconnect over LTE.
a shame apple does not have this wifi share feature.... its killer and an absolute MUST for poly and ARE NOT using mobile data... wifi sharing hijacks the network and allows you to create and name your own personal net... then connect all devices to this.
SWEEEET!
I am in a hotel lobby connected to their internet in Waikiki writing this now listening to Roon via Poly all connected to my S10E which is connected to the hotel network.
