IPhone 5 hotspot unable to connect to computer through Wi-Fi?

Basically my mum bought the iphone 5 but it was broken because you can't hear anything without loudspeaker when talking to someone, so my mum received
the replacement iphone but it's hotspot won't connect to our computer, but the iphone before the replacement hotspot was working perfectly, can someone help?

The new phone may have a different hotspot SSID than the old one. Are you sure you're trying to connect to the new SSID? Did you turn hotspot on in Settings? Is the security key for the new one different than the old one? I'd try deleting the hotspot SSID in the computer and setting it back up fresh.

This is the fix! When you restored your iphone4 to your new 5 the settings conflict. Just do the above. Perfect!
