use panel or grids and certainly not OMNI's for such close range. Use the 40Mhz channel width and wireless "n" noise floor 112 shows some interference at ur site so try and choose the best freq. use Nv2, with 802.11 it still has a tendency to connect at 65.0 mbps or so. NV2 takes it beyon...

What is your signal level? Why do you use Omni antennas to connect two devices, you should use Panel type in this case
