AW: Set allowed mode to 2G, 3G, 4G not working

[Stelling2 Carsten]

Hi Aleksander,

Thank you for your fast response.
With your patch applied to 1.10.0, the error message is still the same.
Is there anything I can provide for debugging?

Hey,

> I'm confused by this error message "Cannot change modes: only one combination supported', because only one mode is given.
