Immediately got good signal and worked very well to hook me up to my apartment complexes weak WI-FI. I bought this to dump my bad thieving ISP by using the complexes signal and despite most neighbors getting poor or useless signal despite being closer to the office/having fewer intervening walls than me this works nicely. I have ordered a YAGI directional antenna to replace one of the stock ones to see if I can get a even faster/better connection but would not have bothered if this did not work so well out of the box as to encourage me to be greedy. Included install disc worked without problems on my Win7 machine.
