The desktop version includes drivers sourced from the Ubuntu kernel package, whereas Touch may include Android-specific drivers. > The second question is, will *iw reg* be added as an option in GUI mode? 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? Regards, /tony > Regards, > > *Sayantan Das* > > ---------------------------------- > Use Linux.
