Roku Ultra: turning off wifi

I have a sensitivity to wifi, EMI and RFI. I also have a Control4 smart home system in place. Can I turn the Roku Ultra wifi off and only use the ethernet connection for content and control? If not for control, is there an IR receiver built into the Roku Ultra?

Roku devices such as the Ultra use WiFi Direct. You can't turn that off.

Maybe the cheap Roku Express that uses an IR remote?

Except that the cheap Roku Express is Wi-Fi only.

If you disable "Device connect" under "Advanced system settings" it may turn off the Wi-Fi completely, but you'll need an IR remote.

Duh. I should have thought about that before I posted. But yeah, if your suggestion does work, they can get a cheap IR remote that supports Roku codes for under $10 from Family Dollar, Walmart, CVS, Best Buy, etc.

Re: Roku Ultra: turning off wifi

I have the same problem. I tried to turn it off and it doesn't work. It still has frequencies that are high. A friend of mine covered his Roku with aluminum foil. The EMF stores have a cover, as well, that may work, but doesn't cut out all frequencies, just lowers it. You'd have to call Roku to see if aluminum foil is OK, so doesn't overheat. It works for my friend. The older models don't have as high frequencies. But, even the Roku 3 is too high. Roku 2 is OK.

Which Roku 2? The model 2720 is a very old and slow device. Is that the one you're talking about?

If it's model 4210. that is actually a Roku 3 inside a Roku 2 case. Yes, the Roku 2 model 4210 is the very same device as a Roku 3. If that's the Roku 2 that you're saying doesn't have as much interference as a Roku 3, then it's not a design issue, so much as an individual device issue. The design is the same. You either got lucky with the Roku 2, or unlucky with the Roku 3. I'd guess the latter.

Re: Roku Ultra: turning off wifi

I have Roku 2 , I guess it's the slow one, but it works. Measured with an RF meter it's low on the scale. My friend measured the Roku 3 and it's high without tin foil over it. Within 4 feet it's still high EMF with the tin fol on it.  As long as one stays 4 feet away they are in the safe range for RF frequencies with the tin foil protection.
