From my experience N900 is not powerful enough for high speeds, if I reach 2Mb/s on torrents the device gets non-responsive until speeds get down. And real life G speed is MAX 3Mb/s,it usually is about 1.6-2Mb/s for me. When accessing windows network it is even slower. So 12-24MBPS is the limit of G in real life, 54 is "in theory". ( I had many routers, laptops so I am talking from experience, no other knowledge ). In short. It is all OK, nothing is wrong or ever will get better. Hope I helped.
