well, Ive got some wi-fi analyser apps on my S3 to make sure i pick the right channel, got some 9dBi Antennas from TP-Link from a left over project and generally speaking I get about 60-70% signal from where i sit so I dont think i'll have much of a problem.
Im trying to find the spec/datasheet on how powerful my current edixmax repeater/extender is so i can compare them but i cant seem to dig up any solid info on broadcast strength and stuff like that. as for the SR20000G, Do want, but its way out of my price range - not that i need half of the features on it that are being advertised.
