Why Is My Wi-Fi not working on my Iphone 4?

I used to be connected to my Wi-Fi, and then it just kicked me off. My dad has tried to add the password, but it does not connect. I use the Iphone as an Ipod so i do not have 3G.

Sometimes you need to switch it off and restart it again.

if you have 'Jailbreak' materials on the iphone, it is possible that you have downloaded something that doesn't agree with iphone Wi-Fi device. You may need to remove Jailbreak by using iTunes (and switching the apps back up on).

Sometimes, the way you hold the iphone can reduce the reception of Wi-Fi (a common antenna problem seen in iphone 4), try using the iphone while it is resting on the table without holding it.

Hope that helped.

  • Why is the emoji 2 app not working on my iphone 4? I have just downloaded emoji 2 on my iphone 4 but the new emoticons are not showing up in my keyboard. When i go to international-add keyboard.emoji isn't there as an option. I've tried deleting and readding the emoji keyboard I already had in settings, I've restarted my phone twice and I've tried both the japanese keyboards. Any suggestions?
  • Why is my iphone 4 screen not working? I dropped it from 2 feet and it landed on the bottom where the Speakers are and i caught it not even a second before it hits the ground, when i tried to turn it on the video i was watching stopped and the screen went blank. I know it still works in general because when i turn it on and drag where the slide is i hear a click, what happened and how can i fix it? i need to fix it within the next hour.
  • Why is Belkin Wi-Fi on iPhone not working? In settings it says that I have got the network and am logged in but in the top left hand corner it shows the mobile data symbol not the normal Wi-Fi one. I stopped using mobile data (lost signal) but when I tried to use Internet it said something along the lines of the webpage failed to load because safari is not connected to the Internet. This is really annoying and it is costing me loads to write this!
  • Why is apple jumping straight to iphone 8 and not 7s and 7s plus? In the past we saw the 4s,5s,6s,3gs, etc. But why not 7s? Can you tell me why they might be skipping the s series? Or is the iphone 8 going to be called the iphone 7s?
