The desktop version includes drivers sourced from the Ubuntu kernel
package, whereas Touch may include Android-specific drivers.

There are no plans to add this feature to the Wi-Fi system settings at
this point.  For more details on Wi-Fi settings, see:

https://wiki.ubuntu.com/Networking#phone-wifi

Although "iw" can be installed from the archive, it's not guaranteed to
work on Touch devices as not all Android Wi-Fi drivers properly support
manual configuration of Wi-Fi regulatory domains.

Have you tried "iw reg" on your device?  Also, what device are you using?
