My iphone 4 wouldnt connect to Wi-Fi

I recently got Wi-Fi access in my room! I tried to connect my iphone ( it has two bars when I clicked on it ) i wrote the pass word in 100% right but It won't connect what's wrong and how can I fix it.

Make sure your Wi-Fi is actually working. Make sure you got the password right. Reset your iPhone and try again

When this happens to me, I usually turn off the Wi-Fi connection on my phone and leave my phone for a while. I then turn it back on and it connects straight away. The other thing you can so is to turn you own Wi-Fi off and on.

  • Wouldnt this be great if it happened? So there's not many jobs here in the US but if these major companies such as nike, apple etc. Would bring over there factorys from china wouldnt there be many jobs for americans here? I mean if you put these factories all over the US, that would slow down crime rate and would better the cities. Ofcourse that would mean that things would cost more but hey people will still buy iphones, shoes etc. On a daily basis no matter how expensive am i right?
  • Why won't my xbox 360 connect to the internet but will connect to my iphone hotspot? Ill play cod bo2 almost daily and my xbox will connect to my mobile hotspot on my iphone 4s fine, but out of no where it will lag out and disconnect me from xbox live, its not a hardware issue everything connects normally, full bars and everything the phone still lets me get on the internet, but my xbox will not, why D:?
  • My Wi-Fi won't connect on my laptop but will connect to my other devices (an iPhone and iPad)? I have a MacBook Air. Sometimes it does connect but other times it just won't. It takes ages connecting and then in the end comes up with the exclamation mark or is just blank. Is this a problem with my laptop? I've tried researching the problem but have found nothing.
  • My iphone will not connect to my home Wi-Fi. It can connect to any other network with no problems All my other devices at home connect with no problem, but once i updated my phone it won't connect here. I've reset the router, my network settings, forgot this network, even wiped out my phone and it still won't work. I changed the dns several times. Sometimes that works for a little while, but then eventually stops. What the hell?
