YUP, same network, same "router" same TV same everything. Connected a
Android TV Streamer ( new version ) guess what NO PROBLEMS AT ALL!,
while the chromacast with android tv HD, (not so old) still crashes. son
DEFINATELY the device that worked well ...
i can confirm that the device ( chromecast with android tv HD for me) i
tried with a Google TV streamer and voila no issue anymore, same
network, same wifi same channel.. so google ha broken it's chromecast
again to force us to change
I recently tested with a newer Google TV Streamer.... SAME network, SAME
house, SAME SSID, same TV, same everything... and Guess WHAT? NO
DISCONNECT AT ALL!!!! so i am 100% confident that the device is the
problem with my Chromecast with Google TV HD...
OK USB hubs, sorry my CCwGTV is direct on its own power adapter so no
HUB involved forme. I tought you were refering to WIFI Hubs (hub is not
used in network for a while  )
