If you have external antennas you can (or at least could) actually try this. Having the RAM just behind the antennas (by holding them in an open case) with a clear line of sight to the router produced significantly worse results than moving the antenna 30cm in either direction. I can't remember which WiFi generation I was testing this with but I remember seeing something like a 40% reduction, worst case.
