I gave DD-WRT fw a try and the 2.4Ghz radio with 20Mhz BW the download was around 2Mbps. At the same location with VINILLA fw download was over 50Mbps.
The 5Ghz radio 80Mhz BW, VINILLA fw showed better (about +10%) transfer speeds that ramped up quicker too, compared to DD-WRT fw _________________ Home Network on Telus 1Gb PureFibre - 10GbE Copper Backbone
