- pmjordan 11y agoI can confirm similar local measurements with MacBook Pros and a D-Link DAP-2950 across a room with a wood partition blocking line of sight. If the AP is advertised as 600Mbit/s, chances are it only supports 1 or 2 streams (MIMO antennas) per band. Most laptops only have 2, but even so the signal quality will be much better wih a 3- or 4- way MIMO setup on the AP end. (The D-Link has 6 antennas, so 3-way MIMO for both 5GHz and 2.4.) In addition to number of antennas, orientation also makes a big difference. Finally, wireless access points seem to be one of those things where quality varies a lot. I hated wifi for its unreliability until I bought a decent (professional/small-to-medium-business grade) AP 8 months ago. Not a single connection problem since, even with the notoriously affected Mac hardware and OSX software versions.
