You can try third party kernels/ROMs which may enable that spectrum but the legality may be an issue depending on your location. It's possible it's still a hardware limitation but more likely is that it's a software limitation.

You may have some luck fiddling with wpa_supplicant.conf per this post.


  As a hint, you need to look into wpa_supplicant.conf to use all the
  5.8Ghz frequencies with the parameters:
  
  p2p_oper_reg_class=
  
  p2p_oper_channel=
  
  For me Korea is 124 and 149
  
  But yes, you need to be rooted
