My roku tv is showing all zeros on the mac address. How can i fix this?
That's not good. Try unplugging it for a few seconds and then plug it back in. If that doesn't work, try a network reset from Settings->System->Advanced system settings->Network connection reset (I'm not sure that option is available for TVs). The last thing to try is a factory reset from Settings->System->Advanced system settings->Factory reset. If none of those work, you'll have to contact your TV's manufacturer. Roku only provides the OS, not the hardware.
