Can not connect to Wi-Fi

can u connect to your wifi with a computer? Try resetting your wifi router. I had a similar problem with my iPhone at work( oh yeah, I use it at work all the time LOL, these #######s don't pay me enough for me to work diligently. I'm at work right now), checked the connection with a pc and couldn't connect either. So long story short the problem is most likely with your router.
