iphone 4s wifi latency

hello,

have problem iphone 4s, 5.0.1 non jb. if ping phone latency great 80-200+ ms while every other device responds 2-5ms. have tried on 10 different access point , same problem happens. iphone has huge latency. have tried close backgrounds apps. might problem? seems it's problem iphone , not access points.

 

you're right. 4s uses new wifi chip "i feel" isn't quite up-to snuff. 4s device drops when using airplay , i'm not one. can fixed via software update.
