    This snippet is suggesting that AP wanted to switch
    channel\bandwidth to dual channel, but your wifi adapter couldn't
    comply with the change, hence forced disconnect.
    I suggest you to reconfigure your AP in a way it supports single
    channel operation only (set it to either 20Mhz or 40Mhz, not both)
    and also if possible, disable auto-channel function of your AP and
    manually select operating channel\bandwidth, so your wifi adapter
    won't have to switch between ever changing channels.
