We added one item to handle this on our 5GHz TODO list. We're unfortunately not working with 5GHz at the moment, but we'll hopefully do so in the near future (prioritization and stuff). I said to you that I would add a FIXME in the code, but I think this is not really necessary, because 5GHz is not fully working anyway, there is definitely still some work to be done (and that's why it is disabled). -- Cheers, Luca.
