So i got my nexus 5 yesterday and i m satisfied so far but..Today i was in my class and the other students told me that there is wifi spot nearby that we could use.But my nexus 5 couldnt find it at all even when i moved near it. The android phones of the other people(galaxy s3 mini,lg g1 etc) could connect to it with 2 bars signal. Soo my question.. Why was nexus 5 the only phone that couldnt find the wifi spot?
