After upgrading the TV in our 05 Pleasure-Way Excel TS, I found that internet access was necessary to utilize the apps built in to the Vizio TV. I'm using a Verizon 4GLTE Home (Novatel T1114) router, which worked great for a local trip last week. Watched Netflix without interruption. I'm adding an omni-directional antenna to increase our range and help us keep signal for longer trips. Has anyone else tried this type of setup for internet access?
