No wired broadband to my house (way off the beaten path). Do have LTE wireless. Samsung Tab 9 android 5.1.1 with LTE cell plan. Have a mini USB to ether net adapter, a net gear wireless router, and chrome cast plugged into tv. I have also the non -chrome device. Want to make the LTE tablet the Wan port to router. Then wireless from cellphone to tv. All is conected as described but can't see the net gear from tablet. The issue is: if cellphone sees wifi, then cellphone defaults to wifi and does not go over the air. Without a Wan connection to wifi I get nothing. Tablet to non-chrome tv device has too many buffer overloads and is unsatisfactory.
