Description

Currently, the control panel's "Radio" checkbox only controls the power to the RF section of the WiFi chip. When the radio is disabled, it should also save massive power (1w or more) by powering off the entire WiFi chip.

When the radio is re-enabled, it should cleanly power-on the WiFi chip and resume whatever radio settings it previously had.

(Note that if Extreme Power Management is enabled, the radio will remain off even if enabled here.)

Related tickets include #8948, #8424, #8062, #7047, #6995. If #6995 is fixed, it may be possible to turn off and power down the radio merely by hitting Disable or Disconnect on the Frame icons for the Wifi and the Mesh. Then this control panel item would not be needed (unless on reboot the system automatically turns on the WiFi -- then this would provide a way to keep it off forever).

COMMENT: There are times (e.g., "under a tree") when I would like to disable listening for signals from Wifi Access Points (which have network-wide IP addresses, and are often connected to the internet), but maintain (e.g., listen on) a mesh channel (where signal originators have mesh-specific IP addresses).

Currently, the Control Panel's "Radio" checkbox will turn off both kinds of over-the-air listening. I like the idea proposed in the #9145 descriptions of "turn off and power down the radio merely by hitting Disable or Disconnect on the Frame icons for the Wifi and the Mesh". If such a control capability is not implemented in Frame, there ought to be TWO checkboxes in Control Panel (for "Mesh over-the-Radio" and for "Wifi over-the-Radio") in place of the single "Radio" checkbox that is there now.
