How to disable WiFi Direct?

By the way, there has been a firmware update since my first post, and there now is a user-configurable "off switch" for WiFi Direct: Settings: System > Advanced system settings > Device connect > Disable Device connect

But I haven't been able to get an answer to my questions over on the Roku forums:

1) Has there been a change in the behavior of Roku's Wi-Fi Direct with the latest firmware update? With my Wi-Fi scanner utility, seems like I used to be able to always see my Roku, but now I only see it momentarily right after boot-up, and then it disappears from the list of all my neighborhood access points.

2) When I go to my Interference setting, there's no checkmark or other indication of the current setting. Is this so for everyone? Anybody know what the Roku factory default setting is?

Anyway, today after choosing Interference as "None" in the Wireless Secret Screen, whenever I reboot just to inspect whether the setting worked, the fleeting appearance of my Roku is still on top of my same Wi-Fi router's channel. (I have all my devices on the 5 GHz band.) Can anyone else confirm whether this fix really works as described in the Net Consonance link (by moving the Wi-Fi Direct channel over to a completely separate channel from my Wi-Fi router's)?

I removed all wi-fi from my home. Don't want the RF pollution. Got ROKU because I wanted a Wired Connection. Problem is, the remote MUST be 'paired' to work. When you change the setting to Disable auto'Connect' .. it says you must disable the Remote pairing .. but you can't disable Remote Pairing. The units produce a huge amount of RF .. I have tested it with a High Frequency Analyzer purchased on lessemf.com . . dangerously high levels. This is a serious flaw in Roku's design that must be addressed.

None of the submenus show you what the current setting is, their menu system really sucks :(

You can disable Device connect in the menu, but only if you have an IR remote control (old gen) since the wifi remote instantly stops working. You also can't do screen mirroring either.

When I turned off the interference, my Roku jumped immediately to another channel far away for the Direct-ROKU-blahblah SSID it broadcasts. No reboot was necessary.

Are you using 2.4ghz or 5ghz? Mine was 5ghz and I'm used wired ethernet for connectivity....

As I said, I have all my devices on the 5 GHz band.... You're the second person to say that the Wi-Fi Direct channel jumped for a wired Roku connection:

Everybody else over on the Roku forums thread said it doesn't work. So it looks like this is only a solution for Roku connections by Ethernet.
