Or move the AP to a more auspicious location.

Support for 11n (ap mode) in OpenWrt (and linux generally) is a bit
shaky at the moment, I think.  I keep saying this, but ... I expect
things to be better in 6 months.  People are actively working on it,
including many of the radio vendors.

802.11n uses three antennas (typically).  Replacing three antennas
probably isn't practical if you want 11n as the cost of reasonable
quality antennas will exceed the cost of a different device.
