Re: [MM] [PATCH 5/5] novatel: Remove band-setting implementation to improve connections

[Nathan Williams <njw google com>]

I'm leery of including code that can run the $NWBAND command to set the modem's state, since as far as I can tell it simply breaks the modem, at least until it is power-cycled. Not setting the bands in the simple connect process unless explicitly requested seems like a fine change on its own, but I think this is too dangerous to include.

I would leave this code around, and instead make sure that if no
bands-specific configuration is given in the simple connect properties,
we don't try to do anything with the bands setup. What do you think?
