iwconfig and the wireless extension (WEXT) interface is mostly obsolete and I believe that it is in the process of being slowly removed from the kernel. Most modern wireless interface management tools on Linux use a more modern netlink-based interface, provided by the cfg80211 subsystem.

I would suggest that you try the iw instead of iwconfig.
