Chosen Solution
I need to be able to disable the wifi on my Vizio E70u-D3. Whether that is through a menu setting or by physically breaking the wireless piece on the inside. I just want it to be a monitor. I don’t want it broadcasting its wifi signal.
This forum entry on another site tells how but sadly it requires a working cat 5 (wired) network connection to disable the wifi. kind of silly if you ask me and I have a vizio tv too!
put in a wrong password when setting up the wifi
If you unscrew all the screws on the back, take off the plastic back covering, you will find one 2.5 Ghz wifi, one 5 Ghz wifi and one Bluetooth antenna (two gray and one black) wires going to the wifi/BT chip towards the very right side (when looking a the TV from behind). You can easily remove the antennas from the chip with your fingernails which greatly reduces the wifi/BT capability (doesn’t completely stop it, but renders it pretty worthless). Takes about 5 minutes.
Under the Network settings, select WPS to start the automatic wifi link, but don’t press the WPS button on your wifi router. The TV looks for the WPS signal/info, and when it doesn’t eventually find it (usually about 90 seconds), it times out, and your already established wifi connection to the TV is broken.
Reset tv to factory defaults.
