How to connect your home internet to the Iphone 4?

I have the Iphone 4 and its confusing me. When I go to click on settings it won't let me click on Wi-Fi to connect it just says "no Wi-Fi". How can I connect my internet on my phone to my home wireless modem?

Also, when i click on settings > general > network > what does VPN stand for? Even beneath that it says no Wi-Fi: S
when I click bluetooth it never loads either
Someone please help me in this! Haha x

You need to have Wi-Fi in your home. Just because you have Internet does not mean it's automatically wireless. VPN is Virtual Private Network. It's used for enterprise and shouldn't really be anything you use.

It's hard to answer any of these things without a discussion. Call Apple Care.

Did have you have your Wi-Fi turned on

VPN is a virtual private network best for a company sponsored connection

You need to make sure your Wi-Fi is working, i would go somewhere with a Wi-Fi hotspot and try and connect that way, if it does then its your internet. If it still doesn't work plug your iphone into a computer and backup your phone then do a restore through itunes. Or you could take it to apple and they will diagnose the problem for free.

Settings>Wi-Fi (second listing under Airplane Mode)>tap on Wi-Fi (not the arrow, the word)>Choose a Network will show>enter your home network name>it will ask for your password, type it in.

  • Why can't my desktop connect to our Wi-Fi at home but does connect to moble hotspot? Suddenly my desktop won't connect to our Wi-Fi. All other devices such as laptops, phones and tablets connects just fine. I tried connecting it to my iphone's hotspot and it works. I tried to unistall and reinstall the wireless adapter but still won't work. I also tried to reboot the router and even tried to change the channel but still failed to make it work. Do you have any other way to make it work? I have windows 7 on my desktop.
  • Which would you get rid of, home internet or iphone if you lost your job? Assuming there was a job loss and you wanted to keep some service would you keep home interent or iphone I'm thinking you can use iphone still with the Wi-Fi.
