A couple of items come to mind here: 1) The amplifier -- it is very possible the amplifier itself is decreasing the quality of the signal being transmitted. WIFI requires very linear amplification. It has been seen that many amplifiers actually distort the signal (especially when the power from the router is more than 2-3dbm ) so while you may have an LQ of 100% in ine direction it could be 0% in the other direction. 2) The Omni -- while omni's may have a place they can pick up noise from all directions, add this to the noise from the amplifier and you may be far enough out that thr node just can't hear you due to local noise. 3) Bullets are single chain devices, having multiple chains (Rocket or Nanostation) has proven to be a better receiver than just a bullet. (Signals while bouncing can change the plane they are in) 4) Distance Paramater -- Ensure this is set do the distance required on both nodes. There is no timeout in units trying to mesh, it will happen continuously. You may want to look at the OLSR Status page and see how the routes look and if you have an NLQ value for the node in question and what the % is and what the RTX cost on the route is . If you have 100% one way but 0% the other than you don't have a connection that would be useable. The PC attached plays no part in meshing only in accessing the services on the mesh.
