Revision 9.2, antennas 5db. I took dir-300 a.1 as a replacement, which, when connected via L2TP, even over a cable gave out more than 6 Mbps. I felt the difference immediately both in speed and in communication range. It breaks through two reinforced concrete walls without problems (the speed drops by half), 4 reinforced concrete walls - at the limit. In general, a good device for the money, I recommend.
