I have a samsung galaxy s4 that (so far) hasn't had any problems. I just moved and it won't connect to my home Wifi. It worked at my old house, works in public (mcdonalds wifi etc). I know it isn't the router/wifi because it works perfectly on my laptop, xbox, boyfriends phone etc.
Ive tried forgetting and reconnecting, battery pull, soft shutdown etc. Im not that techy so if theres anything I could do without having to go to someone that would be great.
